Flat roofing in West Parley

Sun lounges, garages and the wraparound at the back. On a West Parley bungalow the flat roof is rarely a small thing. A sun lounge, a garage joined to the house, a utility running the width of the back, a porch and the covered way between house and garage can add up to more flat roof than some houses have pitched.

Coverings in West Parley run from felt laid up in three layers with a mineral cap sheet to torch on felt over the top of it, GRP fibreglass, and single ply where the run is long. We strip a bay first, because the deck is what the quote turns on. Dry plywood or OSB will take a new covering. Chipboard decking that has been damp sags between the joists and comes off, and new boards are fixed down before anything is laid over them.

Falls, outlets and standing water. Ponding is the real fault behind a lot of wet ceilings, whether or not anyone names it. Water that sits on the surface works into every lap and seam and a frost splits them. It comes back to a fall that was never laid, firrings cut too shallow, tapered insulation squashed flat, or a rainwater outlet choked with moss washed off the main roof. We rebuild the falls so it drains at an outlet instead of holding in the middle, to the minimum in BS 6229:2025 on flat roofs, and check the gutter, hopper and downpipe below take it away.

The perimeter, the upstands and the seams. Very little goes wrong in the middle of a covering. It is the edge trim, the drip, the apron where the flat meets the tiled roof or the wall, the kerb round a rooflight and the laps. Felt blisters, bubbles and splits. Single ply lifts at a failed seam. Fibreglass cracks at a hard internal angle. What has failed is cut out, the upstand is carried up behind the covering to a sensible height, and the seams are welded or bonded rather than layered with more patches.

Openings, abutments and the build up. West Parley bungalows collect rooflights, because a flat roof is often the only way to get daylight into the middle of the plan. Every rooflight, lantern, Velux, hatch and soil and vent pipe needs a kerb and a collar. Where the flat runs into the main roof or a wall we chase in a cover flashing in lead. On a parapet we look at the coping and the cavity tray behind it. These roofs are cold roofs as built, insulation between the joists with a stale void above, which is where condensation collects and interstitial damp rots the deck unnoticed. Rebuilt warm, the insulation goes over the boards with a vapour control layer under it, which brings every joist inside the insulated envelope.

A flat roof cannot be priced honestly by the square metre, because the covering you can see is the smallest part of the decision.

Where it sits. A sun lounge behind a bungalow is reached off a tower on the lawn. A flat link between two pitched roofs has membrane or lead to dress up on both sides. A garage beside a detached house may have a two storey wall above it, and then it needs scaffold, which is its own line because of the HSE roof work guidance.

The deck. Many West Parley extensions from the seventies and eighties were decked in chipboard. Once it has been wet it goes soft and cannot be re-covered. Ply or OSB that is still firm underfoot can. Thomas lifts a corner before he quotes so the deck line is based on what is really there.

The falls and outlets. A roof laid dead level ponds, and a pond finds every weak lap. Putting a fall back in with tapered firrings is extra work, and it is what stops the next leak. Each upstand against the house wall, each edge trim and each outlet into a gutter is priced on its own. BS 6229 is the code of practice for these coverings.

With another quote in hand, ask which system it is (felt, EPDM rubber or GRP) and how many layers, whether the deck is being replaced or covered over, and whether the tower and the skip are in the figure.

West Parley is bungalow country, and that changes the shape of a flat roofing job in three practical ways. There is often a lot of flat roof per household, because the additions are all single storey and they tend to sprawl across the back.

The access is easy, so a tower usually does instead of a scaffold, and that saves a line on the quote. And the roof is usually visible from an upstairs window next door, which is the one time appearance matters on a roof nobody would otherwise see.

The other consequence is worth planning around. On a bungalow the flat roof often sits directly over the rooms you live in rather than over a garage you walk through twice a day, so condensation and a cold deck show up as damp on a ceiling rather than a wet patch on a concrete floor. If yours is going to be stripped anyway, that is the moment to build it back as a warm roof with the insulation above the deck. It is the cheapest it will ever be to do, and it deals with the problem instead of covering it over for the next owner.
