Flat Roofing in Ashmore

The perimeter, because that is what lets go. An edge trim is not decoration. It holds the covering down at the one place wind can get a grip on it, and its drip is what throws water clear of the fascia.

Where fixings have pulled on an Ashmore roof we renew the trim and fix into sound timber rather than screwing back into the same holes. Upstands are carried high enough that driven rain cannot climb over them, and every open edge is priced on its own.

The abutments and the parapet. An upstand against a wall takes a lead cover flashing dressed into a chase. On the older stone and flint work the chase becomes a lead apron worked over the face instead, because cutting deep into a wall like that costs more than it cures. A parapet gets its coping bedded and a cavity tray put in behind. On a roof in Ashmore, this is nearly always where the water is getting in.

What goes back over the top. EPDM rubber on an Ashmore garage or porch, a single sheet with its laps bonded cold and no heat anywhere. GRP fibreglass laid wet over new ply and curing into one skin, which suits a roof carrying a lot of edges. Built up felt in three layers under a torch on mineral cap sheet, still the toughest surface to walk on. Single ply hot air welded where the area is large enough to be worth it.

The boards, and the fall across them. Chipboard decking that has been wet for years has to come off. Ply that gives underfoot goes with it, and OSB is what most of it goes back in. The joists get checked while everything is open and the falls are put right with firrings or tapered insulation, so water leaves at an outlet instead of pooling. A roof laid with no fall at all is the usual reason one fails early.

Insulation, and anything coming up through it. A warm roof puts PIR above the deck with the vapour control layer under it, holding the dew point out of the timber. A cold roof keeps insulation between the joists and has to breathe, or condensation and interstitial damp rot the deck from below. BS 6229 covers how it is built and Approved Document L what it has to reach, and a re-cover engaging either goes through building control. A rooflight, a lantern, a Velux, a loft hatch, a soil pipe or a vent pipe gets its kerb built up and a collar formed, never a bead of mastic. Then the rainwater outlet, the hopper, the gutter and the downpipe are checked before we price the covering.

We do not quote flat roofs by the square metre. What is under the covering decides the job. The deck. Sound boards can simply be covered. Wet chipboard, or old planks on an outbuilding that sag between the joists, are replaced before anything goes on top. We lift a corner before quoting, because nothing moves the price more.

The falls. A roof that ponds was laid flat, or has an outlet that silted up. Firrings restore the fall towards the outlet, which takes longer than a straight re-cover and is why the new one lasts.

Where it drains. The ground in Ashmore is a clay that shrinks and swells, so roof water should go to a proper drain or gully well clear of the wall rather than onto the soil by a footing. Approved Document H covers where it may go.

The system and the edges. EPDM, GRP and torch-on felt membranes are detailed differently at upstands, abutments and edge trims, and each outlet is priced on its own.

Access. A garage comes off a tower, and a roof higher than a two storey wall is worked from scaffold, which the work at height rules oblige us to price openly. A lane with nowhere to park means carrying by hand.

Check any other price for the named system and number of layers, new decking or not, firrings or not, and whether scaffold and skip are counted.
