Flat roofing in Milborne St Andrew

Outbuildings, stores and the room added on the back. In Milborne St Andrew the flat roofs are on the things that were added later: a garage, a workshop, a log store, a boot room, a lean to across the back of the house, and now and then a flat topped dormer.

The coverings are torch on felt, older built up three layer felt finished with a mineral cap sheet, GRP fibreglass from a decade or so ago, and occasionally a small lead flat over a bay. We strip a section before we price, because the deck is what the job turns on. Plywood or OSB that has stayed dry can be re-covered. Chipboard decking that has taken water sags between the joists and has to come off, with new boards fixed down before any membrane goes near it. From there it is EPDM rubber, fibreglass, a new torch on system, or single ply on a long open roof.

Water that will not leave. Ponding is the proper word for it, and it does more harm than it looks. Water sitting on a roof pushes into every lap and seam and the first frost opens them. It comes down to a fall that was never laid, firrings cut too shallow, tapered insulation crushed underfoot, or a rainwater outlet blocked with leaf litter from the trees around the lane in Milborne St Andrew. We reset the falls to drain at an outlet, to the minimum in BS 6229:2025 on flat roofs, and check the gutter, hopper and downpipe below actually take it.

The details, which is where it leaks. Not the middle of the covering. The edge trim, the drip, the apron against a wall, the kerb round an opening and the laps. Felt gives you a blister, a bubble or a split. Single ply lifts at a failed seam. Fibreglass cracks at a sharp internal angle where the deck has been moving. We take out what has failed, form the upstand behind the covering instead of in front of it, and weld or bond the laps, so the finish is one skin instead of a patchwork.

Openings, abutments and how it is put together. A rooflight, a lantern, a Velux, a hatch or a soil and vent pipe wants a kerb and a collar. Where the roof meets brick, flint or cob rendered wall we chase in a cover flashing in lead so it can move without splitting. On a parapet we check the coping and whether a cavity tray sits behind it. Older roofs in Milborne St Andrew are cold roofs, insulation between the joists with a stale void above, and that is where condensation collects and interstitial damp rots the deck unseen. A warm roof puts that right. Insulation is fixed over the deck with the vapour control layer below it, so warm air never meets a cold surface and the timbers keep their strength.

We do not price a Milborne St Andrew flat roof by the square metre. The area takes a minute to measure. The deck and the falls under the covering are what decide the job.

Reaching it. A garage roof beside a drive is a tower job. A dormer on a cottage roof, or an extension tucked behind a house that fronts the main road through Milborne St Andrew, means scaffold carried through a garden, and the platform has to stay up for as long as the deck is open. That is why, under the work at height rules, access has its own line.

The deck. Chipboard that has taken water for years goes soft and has to be cut out and replaced. Ply that is still firm can be re-covered. Nobody can tell which you have from the ground, so Thomas lifts a corner before he writes a figure, because this is the biggest swing in the price.

Falls and outlets. A roof that holds puddles was either laid dead flat or drains to an outlet that has since blocked. Firrings put the fall back, which is extra timber and extra time, and every upstand, outlet and edge trim gets its own price, since those joints are where leaks start.

The system. Torch-on felt, single ply and liquid membranes differ in layers, labour and how they meet an old wall.

Ask any other quote whether the deck is being replaced or covered over, whether firrings are included, which membrane system it is, and whether the skip is in the figure.

Milborne St Andrew has a surprising number of listed entries in and around the village, mostly farmhouses, cottages, walls and outbuildings rather than anything grand. That matters for flat roofing because listing covers the whole building, including a modest lean to or a store attached to it, and it does not stop at the front elevation. A felt roof on a listed outbuilding is still part of a listed building.

So the first question on an older property in Milborne St Andrew is not which membrane you prefer. It is whether the building is listed, and if it is, whether listed building consent is needed before anything comes off. Consent is separate from planning permission and it can apply even to work that looks like plain repair, particularly where an old lead flat would be replaced with a modern covering. We will tell you honestly if we think a job needs it, and put the roof in writing either way so you have something to send with an application. On the newer houses in the village none of this applies at all.

We are about 20 miles away, at our base on Wolverton Road in Boscombe, and cover the village with Dewlish, Puddletown and the Winterborne villages across DT11. For planning and building control your council is Dorset Council.

Most repairs in Milborne St Andrew need no application at all. What decides whether a change to the outside of your house does is who the council is, whether a conservation area or a listing applies, and whether the place sits in a protected landscape.
