Roofing you can rely on, close to home
Coastal exposure means extra wear on Blackrock roofs. Our team handles salt-air damage, flashing repairs and full inspections, with no call-out fees.
Repairs, new roofs and guttering across Blackrock
Blackrock has everything from seafront period houses to modern apartments, and the roofs closest to the coast feel the salt air the most. We repair weathered slates and tiles, renew corroded flashing and gutter fixings, and fix flat roofs on extensions and apartment blocks.
