Flat roofing in Upton

Garages, side returns and the room built across the back. Upton is full of the kind of housing that came with an attached or detached garage and later gained a utility, a dining room or a conservatory roof across the back.

Add porch canopies and flat topped dormers and that covers most flat roofs in Upton. The coverings are three layer built up felt topped with a mineral cap sheet, torch on felt laid over it later, and GRP fibreglass on the more recent work. Pricing starts by stripping a bay and looking at the deck. Plywood or OSB that has stayed dry can be re-covered as it stands. Chipboard decking that has been wet for a few winters sags between the joists and has to be lifted, with new boards fixed down before a membrane goes anywhere near it.

Making the water leave. Ponding is behind a great many flat roof leaks. Standing water pushes into every lap and seam and a hard frost opens them. The reason is usually no fall at all, firrings cut too shallow, tapered insulation crushed by somebody walking on it, or a rainwater outlet blocked with grit. We rebuild the falls so the roof drains at an outlet rather than in the middle, to the minimum set out in BS 6229:2025 on flat roofs, then run water over it and watch the gutter, hopper and downpipe take it away.

Trims, upstands and seams. Flat roofs give up at the perimeter and the penetrations. The edge trim, the drip, the apron flashing where the roof meets the house, the kerb round an opening and the laps are the places to look. Felt shows a blister, a bubble or a split. Single ply lifts at a failed seam where the weld was rushed. Fibreglass cracks at a sharp internal angle. The failed area is cut out, the upstand is rebuilt behind the covering at a proper height, and every lap is welded or bonded so the roof finishes as one skin.

Openings, abutments and the build up. A rooflight, a lantern, a Velux, an access hatch and any soil and vent pipe each get a kerb and a collar, not a ring of mastic. Against brickwork a cover flashing is chased in and formed in lead, and a parapet has its coping and cavity tray checked. Upton roofs of this age are cold roofs, with insulation between the joists and a still void above where condensation gathers and interstitial damp rots the deck from below. A warm roof deals with it properly. Insulation above the deck, vapour control layer under the insulation, no void at all, and timbers that stay dry through the winter.

We do not work to a square metre rate. On a flat roof the new covering is the quick part, and what lies under it sets the time.

Where the roof is. A garage at the end of a drive comes off a tower and you barely notice us. An extension on the back of a terrace means carrying everything through a side passage or the house. A flat-topped dormer over a bedroom needs a scaffold that stays up while the deck is open. The work at height rules make that a priced line.

The deck. Plenty of Upton garages and extensions of that era were decked in chipboard. Once it has been wet it swells and crumbles, and it has to come out. Sound ply can often stay. That one question moves the price more than anything else, which is why we lift a corner before we write a figure down.

Falls and outlets. Many older flat roofs were laid dead level, or drain towards an outlet that has since been built over. Firrings to put a fall back, and new upstands, edge trims and outlets, take time, and they are what stops a roof ponding rather than a new membrane laid over the puddle.

Put a few questions to any other quote: which system, and how many layers; is the deck renewed or overlaid; are the falls corrected; and are the scaffold and skip in the price?

Upton drains into Poole Harbour, and the harbour catchment brings in nutrient neutrality. It is a phrase that worries people unnecessarily, so it is worth being plain about where it applies. Re-covering an existing flat roof, repairing a garage roof or rebuilding a tired extension roof creates no new accommodation, so the rule does not touch the work at all. There is nothing to calculate and nothing to wait for.

It only engages when a scheme creates a new dwelling or separate overnight accommodation, such as an annexe or a holiday let. An extra bedroom in your own house does not normally bring it in, but where it does apply the application has to deal with nutrients before Dorset Council can grant it. That is a planning delay rather than a roofing one, and it can run to months. So if the flat roof is maintenance, book it and get it done. If it is part of a new dwelling or annexe, start the planning side first and let the roof follow, because the roof will be ready long before the permission is.

Upton itself is a Dorset Council address for planning and building control. Thomas Hannen owns the business and comes out himself to look at your garage or extension and price it. A verified customer gave the firm 10 out of 10 on Checkatrade. Coming out to look is free, and so is the written quote that sets every item out.

Most repairs in Upton 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.
