Repairs done right
A repair is only worth doing once.
Too many roofs are “repaired” at the stain on the ceiling, not at the crack above it. We trace every leak to its true source, use matching materials, and stand behind the work in writing — so the same patch doesn’t fail in the next storm.
- Free roof survey with photo report — no obligation
- Fixed-price quote before any work starts
- Matching slate, tile and lead kept on the van
- 5-year workmanship warranty on every repair
What we repair
Every common roof failure, put right.
One crew handles the whole roof — tiles, flashing, valleys, chimneys and gutters — so a repair never gets lost between contractors.
Leak Detection & Repair
Water stains on a ceiling rarely point to the real entry. We trace the leak back to its source — failed flashing, a cracked tile, a perished seal — and fix it at the cause, not just where it shows.
Slipped & Broken Tiles
High winds and frost lift and crack slate and concrete tiles. We replace individual tiles, re-bed ridges, and re-fix verges so the roof plane is whole again.
Flashing & Valley Renewal
Lead and apron flashing around chimneys, abutments and valleys is where most roofs fail first. We dress new lead, reseal joints, and renew valley troughs to move water cleanly away.
Chimney Repairs & Repointing
Repointing crumbling mortar, rebuilding damaged chimney stacks, re-bedding pots, and renewing soakers and counter-flashing — masonry repairs done by hands that started in stone.
Storm & Emergency Response
Fallen branches, torn felt, missing ridges. We make the roof safe fast, tarp and temporary cover where needed, and document everything for your insurer.
Felt, Membrane & Underlay
Perished sarking felt and torn underlay let water past the tiles. We renew failed membranes and restore the secondary defence every roof relies on.

Word of mouth
Neighbours talk. Dry ceilings prove it.
“A leak three roofers had “fixed” kept coming back. Corner Stone found a cracked soaker under the lead and sorted it properly. Dry through every storm since.”
“Storm took out half a ridge and a dozen slates. They were out the same morning, made it safe, and had it fully matched and repointed by the next day.”
“Chimney was crumbling and leaking into the bedroom. Repointed, re-flashed, and re-bedded — tidy crew, fair price, and the warranty is in writing.”
