Garage roof replacement in Harrow
Professional, hassle-free garage roof replacements in Harrow
Thinking of selling a house in Harrow? A buyer's surveyor will often flag an old cement garage roof as possible asbestos, and that can slow things down. Replacing it before you list, or as soon as it starts to fail, takes the question off the table. The Garage Roof Company has completed roofs across HA1, HA2 and HA3, from standard flat-roofed single garages to wider one-and-a-half garages. We remove the old sheets safely, fit a new steel roof and hand you a disposal note, usually within a single day. The price is fixed up front, there is no deposit*, and you only pay once you are happy with the finished roof.

Garages in Harrow
Harrow garages: flat roofs, wide bays and old sheets
A lot of Harrow's housing went up in the 1920s and 1930s, so streets of semis with a garage to the side or rear are common, many with flat roofs that were never meant to last this long. We also see wider one-and-a-half garages that have had extensions or workshops added. The usual problems are cracked or porous cement sheets, rotten edges and blocked or missing gutters. For each job we agree a fixed price from photos, then arrive with the new sheets cut to size. Old sheets come off whole, are double-wrapped and leave site with a licensed carrier. The new 0.7mm Plastisol-coated steel roof, in a colour such as Anthracite Grey, is fixed down the same day, with insulated sheets and new guttering available.
