Roof Carpentry for Sunningdale's Larger Homes
Sunningdale and Sunninghill are dominated by substantial 1930s to 1960s detached houses, with a meaningful number of genuine Victorian and Edwardian villas on the roads around the golf club and Wentworth. Both bring generous roof spans and rooflines that were never built to a standard geometry, which is exactly the situation a cut roof — built rafter by rafter on site — is suited to.
Most of our Sunningdale roof carpentry work falls into two categories: cut roofs for single and two-storey extensions on these larger plots, and loft conversion roof carpentry in properties where the existing roof space is generous enough to justify converting it into habitable space. Both require working from an engineer's or architect's drawing, cutting timber to the specified sizes and grades, and leaving the structure ready for Building Control inspection.
Dormer framing is a frequent request on Sunningdale loft conversions, where the pitch and depth of these older roofs often allow for a genuinely usable room once a dormer is formed. We frame dormers to the engineer's design and to the dimensions set out on the planning drawings, so the finished opening matches what was approved — important on the more prominent Wentworth-area roads where planning scrutiny tends to be closer.
Every structural roof alteration we carry out in Sunningdale is designed by a structural engineer or architect before we start cutting timber; our role is to build precisely to that approved design and leave the work accessible for Building Control.

What We Do
Roof Carpentry We Carry Out in Sunningdale
Cut Roof Construction for Extensions
Rafters, ceiling joists and a ridge board or structural ridge beam built on site to match the pitch and geometry of the existing Sunningdale house.
Dormer Framing
The structural opening cut in the main roof, dormer cheeks and front wall framed, and the dormer’s own small roof built, tying into the existing rafters either side.
Loft Conversion Roof Carpentry
New structural floor joists, reinforced or replaced rafters, and new ceiling joists or collar ties sized to the engineer’s specification.
Hip and Valley Carpentry
Hip and valley rafters set out and cut accurately so the roof covering has a true surface — common on Sunningdale’s hipped roof extensions.
Roof Joists and Structural Ties
Ceiling joists, collar ties, and structural floor joists sized and fixed to the engineer’s specification, positioned to clear headroom and stairwell openings.
Ridge Beam and Ridge Board Installation
A structural ridge beam, often steel-flitched, lifted and fixed for larger spans, with rafters tied into it to the design specification.
Scope
What We Leave to Other Specialists
Roof carpentry, as we carry it out, is structural timber work only. We do not supply or fit roofing membranes, felt, battens for tiles, roof tiles or slates, leadwork, flashing, or guttering. Those trades follow on from the carpentry, usually a roofing contractor or leadworker working to their own specification.
We hand over a finished, inspected timber structure ready for the roofing trades to batten, felt, tile and weatherproof. We also do not design roof structures — structural alterations are carried out to a structural engineer’s or architect’s design, and the completed work is inspected by Building Control.

Common Questions
Roof Carpentry in Sunningdale — FAQs
Do you cover Sunningdale and Sunninghill for roof carpentry?
Yes. Sunningdale and Sunninghill sit within our core working area alongside Ascot and Virginia Water, and we regularly carry out cut roof and loft conversion carpentry on the larger detached houses in SL5.
What is cut roof carpentry, and why does it suit Sunningdale extensions?
A cut roof is built rafter by rafter on site rather than lifted into place as prefabricated trusses. Sunningdale's mix of 1930s-60s detached houses and older villas rarely have a standard roofline, so a cut roof is usually the only practical way to tie a new extension roof into what is already there.
Can you frame a dormer for a loft conversion on a period Sunningdale property?
Yes. We cut the structural opening in the main roof, frame the dormer cheeks and front wall, and build the dormer's own roof structure, tying it into the surrounding rafters. On a period villa this is coordinated with the planning drawings so the dormer sits correctly on the existing roofline.
Do you design the roof structure, or just build it?
We build to a structural engineer's or architect's design; we do not design roof structures ourselves. If you do not yet have a design, we can recommend engineers we have worked alongside in the Sunningdale area.
Do you fit roof tiles, felt, or leadwork?
No. Roof carpentry, as we carry it out, is structural timber only. We do not supply or fit membranes, felt, battens for tiles, tiles, slates, leadwork or guttering — that work follows once our carpentry has passed Building Control inspection.
Will Building Control need to inspect the roof structure?
In almost all cases, yes. Structural roof carpentry falls under Building Regulations and is inspected by the local authority or an approved inspector before it is covered. We leave the structure accessible for that inspection.
How long does a cut roof take to build on a Sunningdale extension?
A single-storey extension roof typically takes a roof carpentry team three to six days, depending on size and complexity — longer where there are hips, valleys, or dormers. We give a specific timeline once we have seen the drawings or the roof itself.
What areas near Sunningdale do you cover for roof carpentry?
Sunningdale, Sunninghill, Ascot, Virginia Water, Windsor, and the rest of Berkshire and South Buckinghamshire.
