Flat roofing in Hangersley

Detached and integral garages. The biggest single group of flat roofs in Hangersley. Most are three layer felt, two underlays and a mineral cap sheet, on a chipboard, plywood or OSB deck, and they fail in a predictable order: the cap sheet weathers, a lap opens, the deck gets wet at that corner, and then it spreads.

Caught early it is a strip and re-lay in EPDM rubber or a modern torch on system. Caught late it is new decking first.

Dormer tops and cheeks. A flat topped dormer is a small roof with a lot of edge, and the cheeks either side are usually the real problem. Water tracks down a cheek, behind an apron that was never dressed in, and shows up below as a roof leak. We re-form the upstands and take the covering high enough that driven rain cannot get behind it.

Wide flat sections and links. Hangersley houses of this era often have a long flat run over a rear extension or between two pitched roofs. Those suit single ply, welded at the laps and mechanically fixed, or GRP fibreglass where there are kerbs and steps in the level. On a large area the falls matter more than the material, and firrings are what create them. Where headroom is tight, tapered insulation does the same job above the deck.

Cold roof to warm roof. Almost everything of this age in Hangersley was built as a cold roof: insulation between the joists, a void above it that was supposed to breathe and usually does not. That is why so many of these roofs are damp underneath without ever having leaked. Rebuilt as a warm roof, the PIR goes over the deck with a vapour control layer beneath it, the timber stays on the warm face and never reaches the dew point, and condensation and interstitial damp stop being an annual problem. BS 6229 covers both build ups and is the reference we work to.

The details that decide it. Blisters and bubbles, a split or crack in an old covering, a lifted or failed seam, ponding and standing water at a low spot. At the perimeter the edge trim, the drip and the apron. Where a roof meets brickwork, a chase cut and a lead cover flashing rather than mastic, and on a parapet the coping and cavity tray. Openings mean a rooflight, a lantern or a Velux on a kerb, plus any soil pipe or vent pipe. Then the downpipe, the hopper above it, the gutter and the rainwater outlet.

A garage, dormer or extension roof in Hangersley has no rate per square metre. Measuring takes minutes; the deck, the falls and the edges decide the job.

Reaching it. In Hangersley, a detached garage on a gravel drive, a dormer top on a chalet and a wide flat section over a rear extension are not the same job, however alike they look on paper. A tower is enough for a garage. Above a two storey wall, scaffold stays up the whole time the deck is exposed, and the work at height rules make that access its own line.

The deck. Many garage roofs were boarded in chipboard, which swells and crumbles once water gets in; ply lasts better but can delaminate. A soft deck has to be replaced, and we cut a small inspection hole or lift an edge before quoting, because the deck is the largest swing in price.

The falls and outlets. Most failed flat roofs never had a proper fall, or the outlet is choked with leaves. Firrings correct the fall, and each upstand, edge trim and outlet is priced individually.

Warm roof upgrade. Insulation boards on top of the deck raise the roof level, so upstands, edge trims and sometimes a door threshold have to rise with it.

Any other roofer quoting in Hangersley should be able to tell you which membrane system they use, whether the deck is being replaced, and whether firrings are going in to fix the falls.

Most repairs in Hangersley 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.
