Structural carpentry is the load-bearing skeleton of a building — the roof, the floor, the beams that hold everything else up. Done correctly, it's invisible: nothing sags, nothing cracks, nothing creaks. Done incorrectly, it's the most expensive mistake a homeowner can make, because everything finished on top of it has to be ripped out to fix it. Ridgeline's structural carpentry is the work other builders call us in for. We cut traditional roofs to engineer-stamped drawings, install trussed roof systems on new-builds, frame complex hip-and-valley intersections, and integrate steel beams with timber framing on extensions and conversions. Every structural job is built strictly to engineer's drawings, with proper fixings (not just nail guns), correct timber grades and full Building Regs compliance. Where calculations are needed, we work with trusted structural engineers we've used for years. Whether you're a homeowner extending your property, a self-builder framing a new home, or a main contractor needing experienced carpenters who can read a drawing — we deliver the structural work to a standard your Building Control inspector will sign off without comment. ### Best for Self-builders needing roof and floor structures cut on-site - Extensions requiring complex hip-and-valley roof intersections - Loft conversions with engineered floor joists and steel beams - Main contractors needing reliable subcontract carpenters - Insurance reinstatement work after fire or storm damage ### When you'll need it - New roof construction on an extension or new-build - Re-roof projects requiring rafter or truss replacement - Loft conversions needing structural floor and roof work - Removing load-bearing walls and installing new beams - Repairing roof structures after storm or fire damage The cost of getting it wrong ## What happens when structural carpentry is botched. Bad structural work doesn't show up immediately. It shows up six months, a year, or five years later — and by then, fixing it means tearing out everything built on top. ### Sagging floors and cracking ceilings Undersized joists or wrong timber grades cause floors to deflect over time. The cracks downstairs are the first warning. ### Roof spread Without proper ties or ridge support, a cut roof slowly pushes the supporting walls outward — a structural failure that's expensive to remediate. ### Building Control rejection Inspectors reject work that doesn't match the engineer's drawings. You pay twice: once for the wrong work, once to fix it. ### Insurance void Structural work that doesn't comply with Building Regs invalidates your home insurance — including any future claims unrelated to the work. ### Resale problems Survey reports flag structural defects aggressively. A botched roof structure can knock 5–10% off a sale price or kill the sale entirely. Our Process ## A clear, step-by-step system from first call to final handover. - 01 ### Drawing Review We review the structural engineer's drawings and confirm timber spec, fixings and any details that need clarifying. - 02 ### Materials & Setting Out Correct grade timber, engineered joists, fixings and connectors ordered and delivered to plan. - 03 ### Cut & Frame Precision-cut on-site or assembled from prefabricated trusses, all to drawing tolerances. - 04 ### Inspection & Sign-off Building Control inspection at structural stage; any required adjustments completed immediately. - 05 ### Handover to Following Trades Structure handed over plumb, level and ready for roofing, plastering or floor finishes. The Benefits ## What you actually get when Ridgeline delivers your project. ### Engineer-spec accurate Built strictly to drawing — no 'near enough', no improvisation on load-bearing elements. ### Building Regs compliant Every job inspected and signed off by Building Control without rework. ### Trusted by main contractors We're the carpenters local builders call when their reputation is on the line. ### On programme We turn up when we said we would and finish when we said we would. Self-builders and contractors plan around it. ### Steel-and-timber composite Confident handling of structures combining steel beams with engineered timber — common on conversions and extensions. ### Single point of responsibility One firm responsible for the whole structure — not five subcontractors blaming each other when something fails.

Structural carpentry isn't one job — it's a category. Here are the specific structures we build most often and what each requires. ### Traditional cut roofs Cut on-site from individual rafters, ridge boards and wall plates. Used on extensions, character properties, and any structure where prefab trusses aren't viable. Requires skilled carpenters who can read pitch, set out birdsmouths and cut intersecting hips and valleys. ### Trussed roof systems Factory-engineered roof trusses lifted into position and braced. Faster than cut roofs and ideal for new-builds and large extensions. Requires precise wall plate setting-out and proper diagonal and longitudinal bracing. ### Hip-and-valley intersections Where two roof planes meet at angles, accurate hip-and-valley framing is critical to prevent leaks and sagging. We've built these on extensions across the North West for over a decade. ### Engineered timber floor joists I-joists and metal-web joists for spans where solid timber isn't practical. We size, cut and install to manufacturer-specific guidance for openings, cuts and bearings. ### Steel beam integration Many extensions and loft conversions require steel beams to remove load-bearing walls. We coordinate with steel suppliers and structural engineers, then frame the timber structure correctly onto and around the steel. ### Wall plates, lintels & openings Properly bedded wall plates, correctly sized lintels and structurally framed openings — the small details that decide whether the structure performs for a century or starts cracking in five years.
