Flat roofing in Furzehill

The fault list, roughly in the order they show. Water standing on a Furzehill roof where it was laid level. An outlet blocked, or swallowed by a later extension. A fold that has cracked. A blister that has gone. A lap that has opened up.

A trim off its fixings. A perished upstand where the covering turns up the wall. Every one of those is a repair, and a repair is what we will quote you if a repair is what it needs.

What a re-cover actually involves. Off comes the old surface. Then the deck gets its inspection and the falls get corrected, before a single new roll is opened. Only then the covering. A plain garage takes EPDM rubber, bonded down in one piece with nothing crossing the middle. Anything walked on takes GRP fibreglass, laid wet and cured into a single skin with the trims built into it. A roof cut about with upstands takes torch on felt, three layers built up under a mineral cap sheet. A large roof takes single ply, welded at the joints. Two to three working days is normal for a garage or a small extension.

Decks and insulation. Plywood, OSB and chipboard, and around Furzehill it is the chipboard that has given up. Firm boards get covered over, soft boards come out and the joists get looked at while there is nothing sitting on them. Falls are set with firrings or by cutting the insulation on a taper. On a rebuild the insulation goes above the deck as rigid PIR with a vapour control layer beneath it, which keeps the timber warm, puts the dew point outside it and leaves interstitial condensation nowhere to happen. Wool packed between joists with no ventilation path is the arrangement that quietly rots, and it is why BS 6229:2025 on flat roofs and Approved Document L both send the insulation upward.

Everything at the edges. A kerb built for a rooflight, a lantern, a Velux, a hatch, a soil pipe or a vent pipe. An upstand and a chased cover flashing at the wall. A lead apron where lead is already there. A cavity tray where the wall has a cavity. Parapet and coping made good. Drip and edge trim set out properly. Gutter, hopper and downpipe below, clear and running, because none of the work above counts for anything if the water ends up on the wall.

Thomas climbs up to the flat roof, lifts an edge of the covering where he can to look at the deck, and writes the price himself. The quote is a list you can check: getting up there, taking off the old felt, any deck boards or firrings, insulation, the new waterproof membrane, every upstand, outlet and edge trim, and clearing away. The whole job comes from one company.

Furzehill's flat roofs are mostly over garages, porches and rear extensions built onto post-war houses and bungalows. Most can be reached from a tower on the drive. The roof is never left open overnight; if the deck is exposed at the end of a day, it is sheeted and battened down. Waste is taken away as we go and the drive swept. If wet chipboard or a rotten joist appears under the old felt, Thomas sends a photo and a price and waits for your go-ahead.

Re-covering an existing flat roof is maintenance, so no planning permission is needed and Planning Portal guidance shows the limits. Building control comes in if you deck over a habitable room, convert a garage, or renew most of a covering so the insulation must meet Approved Document L; that means a building notice or full plans to Dorset Council. No conservation area covers Furzehill, and a listed building needs listed building consent first.

Water through a flat roof usually lands on the ceiling of a garage, a kitchen extension or a porch. Move things out from under it, and if water is near a light fitting, switch that circuit off.

Our booked hours are Monday to Friday, 8am to 6pm, so for this please phone rather than filling in the form; an unanswered call is returned as soon as possible. We get the split, blister or lifted upstand covered and the roof dry, then check how much of the deck has gone before pricing the permanent job, because a wet deck keeps rotting after the rain stops.

Furzehill has no conservation area, and the listed buildings are farmhouses and cottages around the lanes rather than anything in the housing, Wilksworth Farmhouse among them. For an ordinary house that means nobody has an opinion on what goes on your flat roof.

It is a technical choice, not a planning one. The nearest conservation area is Burts Hill and Merrifield at Colehill, a short way off, so if you live toward that side it is worth checking the boundary with Dorset Council.

So let the roof choose. If it is a plain rectangle over a garage with no penetrations, EPDM rubber goes on as one sheet and there is nothing to fail across the middle of it. If people will walk on it, or there is a rooflight, a step or a lot of trim work, GRP fibreglass cures into one piece with its edges and takes the traffic. If the roof is cut up, has several upstands and abuts an older wall, torch on felt in three layers is still the most forgiving thing to lay. And if the deck has to come off anyway, that is the moment to build it back as a warm roof rather than repeat the cold roof that failed. Ask any quote which of those it is pricing, and why.
