What flat roof work do we do in Havering?

Flat roof replacement

Flat roofs in Havering get replaced for the same reasons as anywhere else: the covering has reached the end of its service life, leaks keep returning after repairs, or water ponds because the deck has sagged. Once the boards are soft or the insulation is wet, a full strip usually costs less than another round of patching.

Torch-on felt roofing

Torch-on felt suits property owners in Havering who want a dependable, layered roof without paying the top price per square metre. With two or three bonded layers, a single small defect in one sheet need not lead to a leak, which is a real advantage on larger roofs that are hard to inspect often.

Garage roofs

Garage roofs in Havering are often replaced when the deck gives way. Chipboard decks swell and soften once they get wet, and you may see sagging between joists or feel the roof flex underfoot. Replacing the deck and covering together is usually more economical than repeated repairs.
