Key Takeaways

• Start with build specs: timber grade, cladding type, and frame size indicate real strength.
• Prefer pressure treatment for lower upkeep and longer anti‑rot cover in British weather.
• Match roof materials to exposure; EPDM and high‑grade felt offer reliable protection.
• Solid floors with treated bearers improve lifespan and resist damp from the ground.
• Security upgrades—strong locks and tough glazing—deter theft and damage.
• Assess British shed manufacturers and UK shed companies by warranties, install options, and reviews.
• Balance price with total cost of ownership to find the best garden shed brands UK and top shed makers UK.

What to Look for in a High-Quality Garden Shed

Choosing a shed is easier when you judge the build, not just the look. Check the shed specifications, the timber source, and how the roof and floor are put together. Aim for a secure garden shed that balances strength, weatherproofing, and value over time.

Timber grades, cladding types, and frame thickness

Dense, slow‑grown Scandinavian redwood offers stability and fewer knots. On walls, tongue and groove vs overlap is the key call: T&G or shiplap sheds shed water better and stay tighter in wind, while overlap is a budget choice.

Compare 12mm vs 19mm cladding. Thicker boards feel sturdier, muffle noise, and resist warping. Frames matter too: 28x44mm framing is common for light use; workshops often step up to 38x63mm with closer stud spacing for extra rigidity.

Pressure treatment vs dip treatment

Pressure-treated sheds are impregnated under vacuum, helping preservatives reach the core. Many brands back this with long anti‑rot guarantees. Dip treatment is a surface coat that looks neat on day one but needs regular re‑coating.

If you are near hedges or damp ground, pressure treatment plus raised bearers slows rot and mould. It is a straightforward upgrade that pays back in reduced upkeep.

Roofing options: felt, EPDM, shingles, and metal

Mineral felt is the entry point; polyester‑reinforced versions last longer than basic 3‑tab. An EPDM shed roof comes as a single piece of rubber, ideal for pent designs and known for 20‑plus years of service with minimal fuss.

Bitumen shingles suit apex roofs and give a neat, tiled look. Metal sheeting is tough and shed‑ready, though it benefits from insulation to soften rain noise and limit condensation.

Flooring and bearers for longevity

A heavy-duty shed floor uses 18–22 mm tongue‑and‑groove boards on treated joists. OSB3 is common and fine for light storage, but T&G handles point loads better, such as tool chests and bikes.

Set the shed on ventilated, pressure‑treated bearers to lift it off splash‑back and wet ground. Airflow under the base keeps the floor dry and reduces swelling.

Security, locks, and glazing choices

For a secure garden shed, look for a 3‑lever or 5‑pin lock, a hardened hasp and staple, and security hinges fixed with coach bolts. Anti‑tamper screws at strike plates are a smart extra.

Toughened glass shed windows resist impact and stay clearer than styrene. For workspaces, consider double glazing or polycarbonate panes. Add a breathable membrane behind cladding and check eaves height and door width to make daily use easier.

Feature	Better	Good	Budget	Why it matters
Cladding	19 mm T&G/shiplap	16 mm T&G	12 mm overlap	Thicker boards reduce warping and improve weather seal; tongue and groove vs overlap sets water run-off and rigidity.
Framing	38×63 mm	28x44mm framing	25×38 mm	Heavier frames boost stability and screw-holding strength for shelves and hooks.
Treatment	Pressure-treated sheds	Dipped + yearly top-up	Untreated	Deep preservative penetration resists rot, cutting maintenance and extending life.
Roof	EPDM shed roof	Polyester-reinforced felt / shingles	Basic mineral felt	Single-piece membranes reduce seams; reinforced felt and shingles add durability and style.
Floor	18–22 mm T&G heavy-duty shed floor	18 mm OSB3 with extra joists	11–12 mm OSB3	Thicker T&G handles heavy loads and resists sagging over time.
Glazing	Toughened glass shed windows	Polycarbonate	Styrene	Safety glass improves clarity and impact resistance; polycarbonate is light and shatter‑safe.
Security	5‑pin lock, hasp & staple, coach-bolted hinges	3‑lever lock with hinge screws	Padbolt only	Better hardware deters forced entry for a secure garden shed.

Timber vs Metal vs Plastic Sheds: Which Is Best for British Weather

British rain, salt-laden winds, and sharp cold test every outbuilding. Choosing between timber sheds vs metal sheds and plastic sheds UK calls for a cool look at upkeep, comfort, and security. The aim is simple: weatherproof sheds UK that stand up to daily use without fuss.

Consider your site first. A flat, drained base, clear airflow, and a roof finish that sheds water cleanly will help any choice last longer.

Durability and maintenance in a damp climate

Well-built timber, especially pressure-treated softwood with raised bearers and drip details, copes with wet spells when recoated on exposed faces. Cedar boards add natural oils and keep their shape, which suits weatherproof sheds UK where looks matter.

Galvanised, powder-coated steel resists rot and pests. Yet coastal spray can bite if coatings are scratched, so touch-ups and firm anchoring are key. HDPE and resin models are rot-proof and light to clean, but UV-stabilised panels are vital to limit fade and flex over time.

Insulation, condensation, and ventilation considerations

Timber is the easiest route to insulated sheds. Fit foil-backed PIR or mineral wool with a vapour control layer, then line the interior for steady temperatures and low noise in rain.

Metal shells swing in temperature and are prone to condensation in sheds without anti-condensation felt, thermal breaks, and trickle vents. Add a breathable liner and seal cold bridges around frames.

Plastic needs good cross-ventilation to curb moisture. Retrofitting insulation is limited, so choose reinforced panels and bright interiors to reduce heat build-up.

Security and lifespan trade-offs

For secure garden sheds, brands such as Asgard and Trimetals use heavy-gauge steel, shrouded locks, and ground bolts to resist prying. Timber security depends on frame size, door bracing, and robust locks from makers like Yale or ERA.

Plastic units are light and quick to assemble but usually need steel reinforcement at hinges and hasps. Expect 10–20 years with UV care; premium pressure-treated timber with EPDM roofing and quality paint can exceed two decades; top metal units also reach 20+ years with coatings intact.

Material	Weather Performance	Condensation Control	Insulation Options	Security Profile	Typical Lifespan
Timber (treated softwood/cedar)	Breathes well; suits weatherproof sheds UK with regular recoating and good detailing	Lower risk; natural airflow reduces condensation in sheds	Excellent: PIR or mineral wool plus vapour control layer and lining	Strong with thick frames, braced doors, and quality locks	20+ years with EPDM roof and maintenance
Metal (galvanised, powder-coated)	High rot resistance; watch for coastal corrosion and protect coatings	Higher risk without anti-condensation felt, vents, and thermal breaks	Good with liners and breaks; reduces rain noise and heat swings	Very strong; Asgard and Trimetals excel for secure garden sheds	20+ years with intact coatings and anchoring
Plastic/HDPE (UV-stabilised)	Rot-proof and low upkeep; relies on UV stability and reinforcement	Moderate; needs cross-ventilation to limit moisture	Limited retrofit; choose insulated panels if offered	Basic out of the box; stronger with steel-reinforced hasps and frames	10–20 years depending on sun exposure

Key takeaway for buyers: weigh timber sheds vs metal sheds against plastic sheds UK by site exposure, need for insulated sheds, and the level of secure garden sheds required for your tools or bikes.

Build Quality Benchmarks: Joinery, Fixings, and Treatments

Build quality shows in the bones first. Reputable makers of heavy duty sheds UK publish clear shed framing sizes, specify corrosion‑resistant hardware, and document their treatment regime. Look for brands that state materials by grade and process, not vague marketing lines.

Framing dimensions and joint integrity

For strength, workshop frames should step up to 38 x 63 mm or 45 x 70 mm, with tight stud centres, full‑height corner posts, and diagonal bracing to stop racking. Doors need ledged and braced construction; on premium lines, mortice‑and‑tenon joints keep everything true under load.

Window units are safer when beaded internally, denying easy removal. Robust shed framing sizes pair with housed door frames and straight, planed timber to resist twist. These choices separate light garden stores from true heavy duty sheds UK.

Galvanised fixings and anti-rot guarantees

Hardware should be galvanised fixings or stainless steel to prevent rust streaks. Expect heavy tee‑hinges or solid butt hinges with coach bolts, plus drip edges and barge boards that protect vulnerable lines. For flat or low‑pitch roofs, EPDM must be fixed with the right adhesives and perimeter trims.

A stated anti-rot warranty of 10–25 years only has weight when the timber is treated through‑and‑through and the base stays dry and ventilated. Makers who include exterior‑grade fastener packs and detailed install guides show they understand long‑term performance.

Factory treatments and on-site preservation

Durability starts with kiln‑dried softwood and factory pressure treated sheds using Tanalith E or similar, then finished with micro‑porous coatings from Teknos or Sikkens where specified. In the UK climate, a breathable membrane behind cladding and a damp‑proof course at the base reduce moisture ingress.

On site, seal every cut end with a top‑tier wood preservative UK, keep 50–100 mm ground clearance, clear gutters, and carry out yearly checks. These steps, combined with correct galvanised fixings and verified shed framing sizes, underpin any credible anti-rot warranty on heavy duty sheds UK.

Design and Use Cases: Storage, Workshops, and Garden Rooms

Choose the form by function. A garden storage shed works best when space is simple and efficient. Place a pent roof against a boundary to push rain to the rear, and fit a wide double doors shed for mowers and bikes. Add shelving to lift boxes off the floor. Overlap cladding can keep costs down for basic storage while still doing the job.

For a workshop shed UK, headroom matters more. Aim for higher eaves and strong frames around 38 x 63 mm with 19 mm tongue-and-groove cladding. Go for opening windowed sheds with toughened glazing to vent dust and fumes. EPDM roofing gives long life. Plan cable routes for sockets, task lights, and an insulated shed workspace that stays steady through the seasons.

A garden room shed should feel like a small studio. Use full insulation to walls, roof, and floor, plus a breathable membrane. Double glazing helps with comfort and sound. Cedar or painted shiplap lifts the look, and colour-matched trims can mirror your home.

Consider apex vs pent roof early. Apex brings a classic line and central headroom; pent delivers modern style and tidy run-off. Place doors and windows for light and privacy, away from prevailing wind and tight fence lines. Keep a ramped threshold for easy access with bikes or barrows, and check distance to boundaries to meet height rules for outbuildings.

Optional upgrades can shape daily use. Add a veranda for shade, internal partitions to split storage from a bench area, or an integrated bike store with reinforced locks. Many windowed sheds accept security packs with hidden hinges and hasps, ideal for tools or hobby gear.

Use Case	Core Features	Roof Choice	Doors & Windows	Fit-Out Tips
Garden storage shed	Overlap cladding, compact footprint, strong floor	Pent for boundary siting and rear run-off	Wide double doors shed; fixed windows or none	Wall shelving, hooks, ramped threshold, moisture control
Workshop shed UK	19 mm T&G cladding, 38×63 mm frame, higher eaves	Either; apex for central height, pent for wall storage	Secure single or double doors; opening windowed sheds with toughened glass	EPDM roof, power points, task lighting, insulated shed workspace zones
Garden room shed	Fully insulated walls/roof/floor, breathable membrane	Apex vs pent roof chosen for style and light	Double glazing, ample windows, refined door furniture	Cedar or painted shiplap, heating option, blinds for privacy

Layout shapes comfort and security. Keep glazing where daylight lands, and place benches under clear sightlines. A discreet side door can help if tools are heavy. With mixed-use designs, separate clean and dusty zones, and route electrics high to protect the workspace.

Small touches add polish: colour-match paints to the house, align gutters to soakaways, and position an outdoor socket for chargers. When space is tight, a slim annex for bikes beside the main shell can free the interior for work or leisure.

Delivery, Installation, and Aftercare Services in the UK

Choosing how your shed arrives and goes up matters as much as the model you pick. Across the shed delivery UK landscape, options range from a simple drop-off to a full shed installation service with garden shed base preparation. Plan ahead to match your budget, site, and schedule.

Kerbside delivery vs full install and base preparation

Kerbside drop-off suits confident DIY buyers. Panels arrive flat-packed, and you handle assembly and fixings. Ensure a clear route from the road and a dry, level spot ready to build on.

A full shed installation service removes hassle. Premium makers and regional specialists can assemble on site and offer garden shed base preparation, whether a concrete slab, paving, or a timber subframe. A solid, level base protects the frame, helps doors align, and supports drainage.

Lead times, scheduling, and site access

Shed lead times vary by season and spec. Off-the-shelf units can arrive in days, while bespoke or larger workshops may take four to ten weeks in spring and summer. Confirm dates early to secure your slot.

Installers need access details in advance. Share gate width, turning space, parking, and any steps or tight corners. Most teams require an obstacle-free route and agreement if items must pass over a neighbour’s boundary.

Warranty terms, maintenance plans, and support

A robust shed warranty UK typically includes long anti-rot cover on pressure-treated timber, provided the base is correct and the building is maintained. Painted finishes often carry shorter cosmetic cover. Check for storm exclusions, lock and glazing terms, and conditions that void guarantees, such as soil contact or unapproved changes.

Good aftercare is simple but important: periodic re-coating, light lubrication on hinges and locks, and quick roof checks after harsh weather. Many British brands provide UK-based helplines, spares, and service visits, with optional maintenance plans to keep protection active throughout the warranty period.

Pricing Tiers and Value: Budget, Mid-Range, and Premium Sheds

Understanding shed prices UK helps you match build quality to your plans and site. Think about how you will use the space, how long you need it to last, and the shed base cost before choosing. Balance first price against durability to find long-term value sheds that fit your garden.

What you get at each price point

Budget sheds often use overlap or thin tongue-and-groove cladding at 7–12 mm, lighter 28 x 28 or 28 x 44 mm frames, sand felt roofing, and simple locks. They suit light storage if you keep up with treatment and checks.

Mid-range designs step up to 12–19 mm tongue-and-groove, 28 x 44 or 38 x 50 mm framing, toughened glass, and heavy-duty polyester felt or optional EPDM. Pressure treatment and better hardware make them ready for hobby work or a small workshop.

Premium sheds UK raise the bar with 16–22 mm cedar or high-grade redwood, 38 x 63 mm+ framing, EPDM roofs as standard, double glazing, factory paint, and pro installation. Insulation options turn them into usable rooms across more months of the year.

Hidden costs: bases, electrics, and upgrades

Your budget should include the shed base cost. A timber base can run about £200–£600, while paving or concrete ranges from about £500 to £1,500+ depending on size and groundworks. Good drainage and level footing protect the structure and interior.

Electrics—armoured cable, a consumer unit, sockets, and lighting—often add £400–£1,500+. Insulation and lining may cost £300–£2,000+. Also plan for delivery to remote areas, removal of an old unit, anchoring kits, security packs, guttering, and water butts.

Cost of ownership over 10–20 years

The total cost of ownership shed view matters. A pressure-treated shell with a strong roof and decent glazing can outlast a cheaper build that needs frequent preservatives and roof swaps. Repairs, call-outs, and lost time add up.

Look at how often you will use the space and if it supports power tools or a desk. Usable, insulated spaces improve comfort and protect contents, making them long-term value sheds. Over time, premium sheds UK can retain appeal and function, which supports future resale.

Tier	Typical Build	Use Case	Indicative Extras	Ownership Outlook
Budget	7–12 mm overlap/T&G, 28×28–28×44 mm frame, sand felt	Light storage, seasonal use	Preservatives, basic security, occasional felt replacement	Lower upfront shed prices UK, higher maintenance over time
Mid-Range	12–19 mm T&G, 28×44–38×50 mm frame, heavy felt or EPDM	Workshop, hobby space, regular use	Power, insulation, improved locks and glazing	Balanced total cost of ownership shed with fewer repairs
Premium	16–22 mm cedar/redwood, 38×63 mm+ frame, EPDM, double glazing	Garden room, office, multi-purpose	Pro install, full electrics, factory paint, heating options	Higher initial outlay, strong longevity and value retention

When comparing budget sheds with mid-range and premium options, map the numbers across base, power, and upkeep. This keeps shed prices UK in context and shows how each choice affects the total cost of ownership shed across its life.

Compliance and Practicalities: Planning Permission and Bases

Before you order materials, check how planning permission garden shed UK rules apply to your plot. Most small buildings are classed as Permitted Development outbuildings, but height, siting, and garden coverage still matter. A sound base and smart water management are just as crucial as the walls and roof.

Permitted Development in England, Scotland, Wales, and NI

Under Permitted Development outbuildings, a single-storey shed usually passes if it sits behind the principal elevation, stays under set height caps, and uses less than half the garden. Keep structures within the boundary rules and avoid blocking sight lines or rights of way.

Limits vary by nation. England allows different overall heights depending on distance from the boundary, while Scotland, Wales, and Northern Ireland set their own size and placement thresholds. In conservation areas or near listed buildings, seek local authority advice early.

Plan anchoring into the base design for exposed coasts or high ground. Good fixings reduce racking and help meet safety expectations without complicating the planning permission garden shed UK process.

Concrete slabs, paving, and timber bases compared

Choose shed base types to match weight and use. A cast concrete slab suits heavy workshops and garden rooms, offering a dead-flat, long-term platform. Paving flags over a compacted sub-base work for small to mid-size stores and can be lifted or extended later.

Pressure-treated timber frames with adjustable feet are quick to install, reduce digging, and boost airflow under the floor. Make the base fractionally smaller than the shed footprint so rain cannot bridge and soak the cladding.

Add a membrane and barriers as standard. Lay a DPM on concrete and fit a DPC for sheds between timber bearers and the base to stop rising damp. Confirm level across diagonals before fixing down.

Drainage, damp-proofing, and airflow

Effective drainage for sheds starts with falls away from the walls. Grade the surrounding ground, use gravel skirts, and add French drains for wet plots. Fit gutters and route downpipes to a soakaway or water butt to keep splashback off the base.

Maintain 50–100 mm ground clearance under timber floors and ensure cross-flow openings for steady shed ventilation. Pair vents high and low to purge moist air, and keep vegetation trimmed back to prevent trapped moisture.

Combine barriers and breathability. Use a DPC for sheds at contact points, seal cut ends, and avoid blocking underfloor voids. These steps prolong fixings, preserve cladding, and align with best practice for Permitted Development outbuildings.

Base Option	Best For	Key Advantages	Watch-outs	Moisture Controls
Concrete slab	Heavy workshops, garden rooms, machinery	Highest load capacity; ultra-stable; long lifespan	More excavation; curing time; higher cost	DPM on slab, DPC for sheds under bearers, gutters to drainage for sheds
Paving flags	Small to medium sheds, budgets, phased builds	Modular; easy to adjust; good value	Needs precise levelling; joint movement over time	Compacted sub-base, slight fall, perimeter gravel for drainage for sheds
Timber frame with adjustable feet	Uneven or sensitive sites; quick installs	Minimal digging; excellent airflow; relocatable	Lower mass; requires firm pads and bracing	DPC for sheds on contact points, open voids for shed ventilation

• Confirm the project fits planning permission garden shed UK guidance before purchase.
• Match shed base types to building weight and soil conditions.
• Prioritise drainage for sheds, DPM/DPC layers, and reliable shed ventilation.

FAQ

Who makes the best garden sheds in the UK?

The best maker depends on how you’ll use the shed, budget, and the finish you expect. For premium, installed buildings with top joinery and paint systems, consider Crane Garden Buildings, The Posh Shed Company, and Malvern Garden Buildings. For strong value, Power Sheds, Tiger Sheds, and Forest Garden offer pressure-treated ranges and quick lead times. For high security, Asgard and Trimetals lead with galvanised steel units, some with Secured by Design options.

What timber grades and cladding should I look for?

Choose dense, slow-grown Scandinavian redwood with 16–19 mm tongue-and-groove or shiplap cladding for weather resistance. Overlap cladding is a budget choice and needs more maintenance. Check frames: 28 x 44 mm is standard; 38 x 63 mm or larger is ideal for workshops and longevity.

Is pressure treatment better than dip treatment?

Yes. Pressure treatment drives preservative deep into the timber and typically carries 10–25 year anti-rot guarantees. Dip treatment is a surface coat and needs annual re-coating. Look for Tanalith (or equivalent) and factory kiln-drying for best results.

Which roof covering lasts longest: felt, EPDM, shingles, or metal?

EPDM rubber is a single-piece membrane that can last 20+ years and suits pent roofs. Heavy-duty polyester-reinforced felt outperforms basic sand felt. Bitumen shingles look smart on apex roofs. Metal sheet roofing is durable but can be noisier unless insulated. Ensure proper drip edges and trims.

What flooring and bearers improve shed lifespan?

Opt for 16–22 mm tongue-and-groove floorboards on pressure-treated bearers. Raised, ventilated bearers keep splash-back and damp at bay. OSB3 is common but less robust than T&G. Maintain 50–100 mm ground clearance for airflow.

How do I secure a shed against theft?

Fit a 3-lever or 5-pin lock, heavy hasp and staple, and security hinges fixed with coach bolts and anti-tamper screws. Choose toughened safety glass or polycarbonate glazing. Metal sheds from Asgard or Trimetals provide integrated locking shrouds and thicker steel for higher resistance.

Timber vs metal vs plastic—what’s best for British weather?

Pressure-treated timber with good detailing breathes well and is easy to insulate. Metal resists rot and insects but needs anti-condensation treatment and firm anchoring. Plastic (HDPE) from Lifetime or Keter is low-maintenance and corrosion-proof, though insulation options are limited. Consider site exposure, maintenance plans, and security needs.

How do I handle condensation and insulation?

Timber sheds accept insulation easily: foil-backed PIR or mineral wool with a vapour control layer and internal lining. Metal sheds benefit from anti-condensation felt, thermal breaks, and trickle vents. Plastic sheds need cross-ventilation; insulation upgrades are modest. Add breathable membranes behind cladding on higher-end timber builds.

What are the key build quality benchmarks?

Look for robust framing (38 x 63 mm+), close stud spacing, full-height corner posts, and diagonal bracing. Premium doors are ledged, braced, and ideally mortice-and-tenon. Windows should be internally beaded. Specify galvanised or stainless fixings, heavy tee-hinges, and proper EPDM adhesives and trims.

Do UK shed brands offer installation and base preparation?

Many nationwide retailers provide kerbside delivery of flat-pack panels. Premium makers and regional specialists such as GBC Group and Malvern Garden Buildings offer installation and, in some cases, base construction. Ensure clear site access, a level base, and confirmed lead times before booking.

What delivery lead times should I expect?

Modular house brands like Power Sheds and Garden Buildings Direct can deliver in days. Premium and bespoke buildings from Crane or Bakers Garden Buildings may take 4–10 weeks or more during peak seasons. Plan ahead in spring and summer.

What warranties are typical for garden sheds?

Pressure-treated sheds often include 10–25 year anti-rot guarantees, subject to correct base, maintenance, and no ground contact. Painted finishes may have 1–3 year cosmetic cover. Review terms for storm exclusions and lock coverage, and keep up with aftercare such as re-coating and roof checks.

How much should I budget for a proper base?

Approximate costs vary by size and groundworks: timber frame bases from around £200–£600, paving or concrete slabs from roughly £500–£1,500+. Include a damp-proof membrane for concrete and a damp-proof course between timber and base. Keep the base fractionally smaller than the shed footprint.

What are hidden costs to factor in?

Allow for electrics (armoured cable, consumer unit, sockets, lights), insulation and lining, delivery to remote areas, removal of old sheds, anchoring kits, security packs, and guttering with a water butt or soakaway. These can outweigh initial savings on a budget shed.

Do I need planning permission for a shed in the UK?

Most sheds fall under Permitted Development if single-storey, not forward of the principal elevation, within height limits, and occupying less than 50% of the garden. Rules differ across England, Scotland, Wales, and Northern Ireland, and special areas may have extra controls. Check local guidance before ordering.

What base type should I choose: concrete, paving, or timber?

Concrete slabs offer the most stable platform for heavy workshops and garden rooms. Paving on a compacted sub-base suits small to medium sheds. Pressure-treated timber bases with adjustable feet are quicker and improve airflow. Ensure good drainage, ground fall, and secure anchoring on exposed sites.

Which brands are known for craftsmanship and materials?

Crane Garden Buildings, The Posh Shed Company, Bakers Garden Buildings, and Rowlinson are noted for higher-grade timber, joinery, and finish options. Retailers such as Tiger Sheds, Forest Garden, Shedstore, Waltons, and Power Sheds provide wide ranges, pressure-treated options, and UK support. Look for FSC timber, EPDM upgrades, and transparent specs.

How do I choose the right design for storage, a workshop, or a garden room?

For storage, choose pent roofs for boundary placement, wide doors, and shelving. For workshops, prioritise higher eaves, 19 mm cladding, 38 x 63 mm frames, ventilation, toughened glazing, and EPDM roofing. For garden rooms, specify full insulation, double glazing, breathable membranes, and painted finishes like Teknos or Sikkens systems.

What is the cost of ownership over 10–20 years?

A pressure-treated shed with robust roofing and proper base usually costs less to maintain than a cheaper unit needing frequent re-felting and preservatives.
