Nearly every flat roof around Minstead is a later addition on an older building. A garage, an outshot, a porch or a rear extension. So the job is nearly always about the junction where new meets old, and that is the first thing we look at.

How the trouble shows varies. Moss has taken hold across the surface and holds water in a green stripe. A dark patch has appeared high on a bedroom wall. Or the gutter under the roof runs over every time it rains properly. Buildings out in Minstead are spread about and no two of them are quite the same, so we turn up without assuming anything and without a price in mind. We get up safely, follow the falls, look into every outlet and at every abutment, and go inside wherever there is something worth seeing. Then you get a written price rather than a figure over the phone. If water is coming into a room under one of these roofs now, ring 07435 839745 and tell us where it shows.

Small roofs, and getting them right

Repairs, which is what most of these roofs need. Out among the trees the outlet is the usual offender, filled with leaf litter and moss until nothing drains at all.

After that comes a cracked fold, a risen blister, a seam that has opened at a lap, a trim off its fixings, or an upstand gone perished at the wall. None of those is a new roof. We follow the falls back from the stain to work out where water is really getting in.

Re-covering. A surface that has stopped bending has to come off. On the small, cut about roofs common in Minstead, torch on felt built up in three layers under a mineral cap sheet is the most forgiving thing to lay. A plain rectangle is quicker and tidier in EPDM rubber, one bonded sheet with nothing across the field. GRP fibreglass is laid wet and cures into a single skin with the trims part of it, so it suits anything walked on. Single ply gets welded at the joints and belongs on a large roof. A small roof can be a single day, a garage or an extension two to three working days.

Under the covering. Plywood, OSB, chipboard or older boarding, and the state of it decides the price more than anything else does. Firm decking can be covered over. Anything that gives underfoot comes off, and we look hard at the joists while they are open. Standing water is a fall fault, corrected with firrings or with insulation cut on a taper rather than papered over with a new surface. On a rebuild above a heated room the insulation belongs on top of the deck: rigid PIR with a vapour control layer under it, timber held above the dew point, interstitial condensation designed out. That is what BS 6229:2025 on flat roofs sets out and what Approved Document L asks for.

Everything it touches. A generous upstand and a cover flashing chased into the wall. A lead apron where lead is already on the building. A cavity tray where there is a cavity. Parapets and copings taken as part of the roof. A kerb built to carry 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 under it, because a new roof draining into a split gutter simply moves the damage down the wall.

How it runs

Re-covering a flat roof on a garage, porch or back extension

Thomas comes out from Boscombe to Minstead, gets up on the flat roof, presses on the deck and lifts an edge where he can, then writes the price himself. The quote splits out access, stripping the old covering, any new deck or firrings, the insulation, the membrane, each upstand, outlet and edge trim, and disposal, so you can hold it against anyone else's line by line. The whole job comes from one company.

On a Minstead property the flat roof is usually a garage, a porch, a dormer or a single storey addition at the back, often reached across a lawn or past a gravel drive rather than from the lane. Materials come in by hand if a vehicle cannot get close, and we never park on the open verge. The roof is made watertight before we leave each day, the offcuts and old felt go with us, and if the deck is rotten further in than we could see, we send you a photo and a separate figure, and the new boards wait for your go-ahead.

Re-covering in the same way as before is maintenance and needs no planning permission, with Planning Portal guidance marking the limit. The planning authority is the New Forest National Park Authority, and permitted development is narrower inside a conservation area, so anything that changes how a building looks is worth checking on the National Park Authority's interactive property map first. Building control applies separately wherever a new deck goes over a habitable room.

The deck, the falls and the way in

We do not price a Minstead flat roof by the square metre. The area is the quick bit to measure; the deck underneath is what decides the job.

How we reach it. A porch roof comes off a ladder. A garage or a single storey extension usually comes off a tower, and anything above a two storey wall wants a scaffold that stays up while the deck is open. Out in Minstead the tower often has to be carried round the house, because there is no hardstanding at the side. The work at height rules make that a priced line.

The state of the deck. Chipboard that has been wet under old felt for years goes soft and has to come off. Ply that is still firm can be covered. Under heavy tree cover a flat roof stays damp longer between showers, so we lift a corner before quoting rather than guess.

Falls and outlets. A roof laid dead level ponds, and leaves and needles block the outlet at the lowest point. Putting a fall back with firrings adds time, and it is what stops the pond. Each upstand, edge trim and outlet is priced on its own.

The system. An EPDM rubber membrane, GRP fibreglass and torch-on felt in layers all cost and last differently, and on a warm roof the insulation and vapour control layer are part of the price.

Ask anyone else quoting which system and how many layers, whether the deck is renewed or overlaid, whether the falls are corrected, and whether the scaffold and skip are included.

If it is coming through

Water dripping through under a flat roof

A split, a blister that has burst or a lifted upstand puts water straight onto the ceiling below, and a wet deck keeps rotting after the rain stops. Move what you can out of the way, catch the drip, and switch off lights on that ceiling if water is near them.

The first visit gets a temporary cover or patch over the failure and checks how far the water has spread through the deck, and the permanent repair is priced once we can see it. Our scheduled hours are Monday to Friday, 8am to 6pm. When it is urgent, call us instead of filling in the form, and if the phone goes unanswered we will get back to you as soon as we are able.

Worth knowing

What like for like actually means in a conservation area

Inside a conservation area the safe route is always like for like, and on a flat roof that is usually easy because so few of them can be seen from anywhere public. The catch is that like for like is not as simple as it sounds.

The mineral felt that went on these Minstead roofs decades ago is not what you would buy today, and a modern equivalent can look markedly lighter or greyer once it is up. If your roof is one of the ones you can see across the green or from a lane, that difference is the thing an officer would notice.

So we write the specification properly: which system, how many layers, what colour and profile the cap sheet is, what the trims and the flashings are made of. It gives you something to hand over if anybody asks, and it removes the argument before it starts. The same care applies to putting a rooflight into a slope that is visible, and if the building itself is one of the listed ones around Minstead, consent comes before the material changes rather than after.

Questions

Questions about flat roofs in Minstead

Do I need permission to re-cover a flat roof here?

You do not need permission for like for like work in Minstead. A new covering on an existing roof is maintenance, so there is nothing to apply for. It changes if the shape of the roof alters, if the appearance changes noticeably where it can be seen, or if the building is listed. Tell us the address and we will check before quoting.

Leaves keep blocking my outlet. Is there a fix?

Partly: a leaf guard at the outlet helps and so does making sure the fall actually runs to it, but on a roof under trees nothing removes the need to clear it now and then. What we can do is get the falls and the outlet sized right so a blockage backs up slowly, not instantly.

Can a flat roof be insulated without taking it off?

Sometimes from below, between and under the joists, but that turns it into a colder deck and needs a vapour control layer and ventilation thought through, or you trade a leak for condensation. If the covering is due anyway, insulating above the deck as a warm roof is the better answer.

How long will it take and what happens to the old roof?

A small roof is often a day, a garage or an extension two to three working days. The strip out is the messy part and it is the first morning. Everything that comes off leaves with us, the site is swept at the end of each day, and nothing is left open overnight.
