Dormer roofs

A dormer roof that has been patched several times in Great Sankey often has layers of old repairs that hide the real fault. Stripping back to the deck shows what has been going on, and lets the team rebuild the back-edge abutment properly rather than sealing over it again.

Warm roof insulation upgrades

Small commercial buildings in Great Sankey with large flat roofs can lose a lot of heat through them. Where the roof is being replaced, upgrading the insulation at the same time is required in most cases and helps reduce running costs for the occupier.
