Shiplap vs Tongue & Groove Sheds
Shiplap Cladding vs Tongue & Groove Cladding: Shiplap Cladding is best for summerhouses, garden rooms, visible garden buildings where appearance matters (£1,500 – £5,500 (complete shed)). Tongue & Groove Cladding is best for workshops, heavy-duty sheds, exposed sites, maximum weather protection (£1,400 – £6,000 (complete shed)).
- Area served
- Edinburgh, Lothians, Fife & Falkirk
Both shiplap and tongue & groove are premium cladding options that far outperform basic overlap. But which is better for your shed? Here's a detailed comparison for Scottish conditions.
Head-to-Head Comparison
Shiplap Cladding
Best for: Summerhouses, garden rooms, visible garden buildings where appearance matters
Typical cost: £1,500 – £5,500 (complete shed)
Pros
- Rebated overlap sheds rain effectively
- Attractive shadow-line appearance
- Good weather resistance
- Allows some timber movement
- Slightly easier to replace individual boards
Cons
- Not quite as tight a seal as T&G
- Slightly less structural contribution
- Can trap water in the rebate if not treated
- Marginally less wind-resistant
Tongue & Groove Cladding
Best for: Workshops, heavy-duty sheds, exposed sites, maximum weather protection
Typical cost: £1,400 – £6,000 (complete shed)
Pros
- Tightest possible joint between boards
- Maximum weather resistance
- Strongest structural contribution
- Excellent wind resistance
- Smooth, flat wall surface
Cons
- Less forgiving of timber movement
- Can split if boards expand significantly
- Individual board replacement slightly harder
- Flat appearance — some prefer shadow-line
Scottish Weather Suitability
In Scotland's driving rain, both shiplap and T&G perform significantly better than overlap. The difference between them is more subtle — both provide effective weather protection when properly treated and maintained.
T&G has a slight edge in extreme weather. The full tongue joint creates a tighter seal than the shiplap rebate, making it marginally better at keeping out wind-driven rain in very exposed positions.
Shiplap has an advantage in handling timber movement. The rebated design allows boards to expand and contract slightly without opening gaps, which can be beneficial in Edinburgh's variable conditions.
Cost Breakdown
Shiplap and T&G sheds are similarly priced. Shiplap boards cost marginally more to machine, but the difference at shed level is typically less than £100.
The real cost difference comes from board thickness. Both styles are available in 12mm, 15mm and 19mm+ thicknesses. Thicker boards cost more but last significantly longer.
We recommend minimum 15mm for either style in Scotland. The additional cost of 15mm over 12mm is around £100-200 for a standard 8×6 shed — excellent value for the extra durability.
Planning Guidance
Both cladding types are equally acceptable under Scottish planning regulations. Neither has any advantage or disadvantage for planning purposes.
In conservation areas, planners may express a preference for one style over the other based on local character, but this is rare for garden sheds.
Both styles can be stained in natural wood tones that blend with Edinburgh's stone architecture, which is preferred by planners in sensitive locations.
Our Verdict
Both shiplap and tongue & groove are excellent choices for Scottish conditions. The difference between them is much smaller than the difference between either and budget overlap cladding.
Choose shiplap if appearance is important — the shadow-line look suits summerhouses, garden rooms and buildings that are a feature of the garden. Choose T&G for maximum weather protection on workshops, utility sheds and exposed sites.
Edinburgh Shed Centre uses both styles depending on the application. We're happy to advise which suits your specific situation — and both come with our quality build guarantee.
