Flat roofing in Walhampton and Portmore

Roofs over rooms you live in. A flat roof over a kitchen or back extension leaks into a ceiling rather than into a garage, so it gets the most care. The deck has to fall to an outlet instead of sitting dead level, and where the roof meets a door the threshold needs enough height under it that water backing up cannot run indoors.

GRP fibreglass cures into one skin with its trims and suits a roof with plenty of detail. Single ply, welded at the joints, suits a larger roof with long straight runs. Behind any wall or parapet the upstand has to be formed, not sealed.

Repairs and re-covering elsewhere. A cracked fold, a burst blister, an opened lap, a trim off its fixings or an outlet packed with debris are hours rather than days. Where a covering has gone hard it comes off. A bin store or plain garage takes EPDM rubber, bonded down in one sheet with nothing crossing the middle. A roof full of upstands takes torch on felt, three layers under a mineral cap sheet. Two to three working days is normal for a garage or a small extension.

Deck and insulation. Plywood, OSB or chipboard, and the chipboard is the one that softens. Firm decking is covered over, soft decking comes out and the joists get inspected while they are bare. On a Walhampton and Portmore roof, ponding means the fall is wrong or the outlet has been built over, and firrings or tapered insulation correct it. Over a heated room the rebuild belongs as a warm roof: rigid PIR above the deck, a vapour control layer under it, the timber held above the dew point and interstitial condensation designed out. BS 6229:2025 on flat roofs sets it out and Approved Document L applies wherever there is a room below.

Abutments, openings and rainwater. An upstand with a cover flashing chased into the wall. A lead apron where lead is already there. A cavity tray where the wall has a cavity. Parapets and copings, which on an older building are very often exactly where it is failing. A kerb built for a rooflight, a lantern, a Velux, a hatch, a soil pipe or a vent pipe. Then the drip, the edge trim and the gutter, hopper and downpipe, because a downpipe that cannot cope puts water down a wall everyone can see.

A flat roof is judged by what is under it, so Thomas comes out himself, lifts an edge where he can and presses on the deck before he writes a word. His quote then shows access, stripping the old felt or asphalt, any replacement deck boards or firrings, insulation, the membrane, and every upstand, outlet and edge trim, plus disposal. His quote is the one price for all of it, from the first board to the final trim.

Where a flat roof can only be reached through the house or across a neighbour's garden, we agree the way in with you, and any managing agent, along with where materials sit and on which days. Garages and single storey extensions behind the older cottages usually come off a tower in the garden. At the end of each day the roof is made watertight, and old covering and offcuts leave in our bags. If the deck has rotted beyond what we could see, we stop, photograph it and price it, and carry on only when you say so.

The New Forest National Park Authority deals with planning. Re-covering like for like needs no permission, and Planning Portal guidance shows where that stops. Permitted development is narrower inside a National Park, so anything that alters the look of a building deserves a check on the Authority’s interactive property map first. Walhampton itself lies in the Forest South East Conservation Area, and a Portmore address is worth checking on the same map. Building control is a separate matter and applies where a new deck and insulation go over a room you live in.

Please phone rather than using the form. Once a flat roof has split, blistered or peeled at an upstand, water gets into the deck and carries on spreading after the rain stops. Catch the drip, clear the room under it and stay off the roof itself.

Our first visit puts a temporary cover on and gets the water away, and we check how much of the deck is wet before pricing the permanent fix. If a flat roof is leaking into a flat below, let that neighbour and the managing agent know so their ceiling can be checked. Our working week is Monday to Friday, 8am to 6pm. A missed call about a leak gets returned as soon as we can.

If you live in a flat or a maisonette in Walhampton and Portmore, the roof over your head usually belongs to the freeholder and is paid for out of the service charge, not by you directly. So when a ceiling stains, the fastest route is not ringing a roofer.

It is finding out who manages the building and telling them, in writing, what has happened. We will still come and look, and we will put what the roof actually needs in writing so you have something to send them.

There is one thing worth knowing early if you sit on a residents' company or a management committee. Where work would cost any single leaseholder more than a set amount, the leaseholders have to be formally consulted before it is committed, under section 20 of the Landlord and Tenant Act 1985. That moves the timetable rather than the roof, and it is a great deal easier arranged in spring than in the middle of a wet November. Getting a written itemised quote in front of people early is usually what unsticks it.
