Pitched roof construction in Alton for extensions, loft conversions, garages and new builds. We build from the wall plate up, with the structure, membrane, battens and covering all done by one team.
A pitched roof is built either with cut timbers on site or with trusses made to order. Cut roofs suit awkward shapes and extensions. Trusses go up faster on a straight run. We work out which is right for the span and the shape of your building.
More Information
An extension roof that meets the house needs the right pitch and the right tile, or it stands out. We match the covering and set the pitch to line through with the main roof where possible, then flash the join properly so it does not leak.
Warm air rising from the house has to escape or it condenses on the cold timbers. New roofs are ventilated at the eaves and the ridge to keep air moving. It costs very little to build in and prevents damp timbers a few years down the line.
STILL NOT SURE?
Often, yes. Replacing a flat extension roof with a pitched one drains better and lasts longer. It needs the walls checked for the extra load and usually needs building regulations approval. We look at the structure first and tell you if it works.
A garage or single storey extension roof usually takes about a week from first timber to last tile. Larger roofs take longer, and the weather plays a part. We give you a realistic timescale with the quotation rather than a best case one.
Yes. We often come in to do the roof once the walls and wall plate are ready, then hand back for the internal work. Talk to us early so the roof is priced and booked in, because it is the part that holds up everything after it.
Prestige Roofing works as a construction company as well as a roofer, which means we build pitched roofs from scratch rather than only recovering them. Over 10 years around Alton we have built roofs for extensions, garages, loft conversions and outbuildings. Free quotations on all of it.
