What we do
Every layer above your ceiling, mastered.
From emergency leak repair to full slate restoration, one crew handles the whole envelope — roof, gutters, flashing, and chimney — so nothing falls between contractors.
Roof Replacement
Careful re-roofing with natural slate, clay tile, concrete tile, or standing-seam metal — specified for the character of your home and the demands of British weather.
Roof Repair
Leaks, slipped tiles, failed flashing, storm damage. We find the true source, fix it properly, and stand behind the repair in writing.
Preventive Maintenance
Seasonal inspection programmes that catch small failures before they become interior damage — with photo reports after every visit.
Gutters & Flashing
Cast iron and aluminium gutters, lead flashing, valleys and eaves details — the work that moves rainwater safely away from your home.
Chimney & Masonry
Repointing, crown rebuilds, counter-flashing and stone repair, true to the masonry craft our name is built on.
Storm & Insurance Work
Emergency response, documented damage assessments, and clear support for your insurer when severe weather leaves your roof exposed.

Why Corner Stone
A roof is only as honest as the hands that build it.
We started as masons — the name comes from the stone our founder set on his first chimney job. Twenty-five years later, that same standard holds: do it right, document everything, and never sell a roof a house doesn’t need.
- In-house crews only — no subcontracted labor, ever

Word of mouth
Neighbors talk. Roofs prove it.
“Three companies quoted us a full replacement. Corner Stone showed us photos, fixed the actual leak, and saved us nearly twelve thousand dollars. That honesty is why they’ll roof every house we ever own.”
“The crew treated our 1928 slate roof like a restoration, not a demolition. Every tile matched, every copper seam soldered clean. It looks better than the day the house was built.”
“A branch came through the roof at 11pm in a windstorm. They had it tarped by 1am and the insurance paperwork handled by Friday. You cannot put a price on that kind of calm.”
