Keystone Roofing & Building covers Mill Hill and the surrounding area, from quick repairs after a storm to full roof replacements and extensions.
Mill Hill mixes 1930s semis and detached houses with older properties around the Mill Hill Village conservation area, where we match existing tiles and slates to keep the roofline right.
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 Mill Hill
Can you match the old tiles on my Mill Hill house?
Usually, yes. We source matching or reclaimed tiles and slates so repairs blend in, which matters around the Mill Hill Village conservation area.
Do I need permission to re-roof in Mill Hill Village?
Like-for-like replacement usually does not, but changing materials in a conservation area can. We can advise and check with Barnet Council first.
