Keystone Roofing & Building covers Finchley and the surrounding area, from quick repairs after a storm to full roof replacements and extensions.
Finchley is mostly Edwardian and 1930s semis and terraces, so bay window roofs, porch canopies, chimney stacks and tired concrete tile roofs are common jobs. Our registered office is on Ballards Lane, N3.
Every job starts with a free inspection and a written, itemised quote. If a repair will do, we’ll quote for a repair.

Questions from Finchley
Do you cover East Finchley and North Finchley as well as Church End?
Yes. Our registered office is on Ballards Lane, so all of Finchley — N2, N3 and N12 — is on our doorstep.
The ceiling above my bay window is damp. What is causing it?
On Finchley’s Edwardian and 1930s houses it is usually the flashing where the bay roof meets the wall, or rotten timber in the bay roof itself. We check both before quoting.
