About Roofing & Exteriors
Everything above the brickwork — and everything that protects it.
We've been roofing and improving exteriors across Greater Manchester since 1998. Full re-roofs, flat roofs, fascias, soffits, guttering, cladding, dormer transformations and storm repairs — every aspect of the building envelope, handled by one trusted team.
Roofing is the one job on your house where a small problem, ignored, becomes a very expensive one. Slipped tiles, failing lead flashing, blocked gutters and worn dry ridges all let water in — and by the time you see a stain on the ceiling, the joists behind it are already wet.
We handle everything above the brickwork — full re-roofs, flat-roof replacements, fascia and gutter renewal, chimney and lead work, cladding and dormer transformations, plus emergency storm repairs across Greater Manchester.

Aftercare
Two checks a year saves five-figure bills.
- Clear gutters and downpipes every spring and autumn — leaves and moss cause more roof damage than storms
- After a storm, look up from the pavement — any slipped tile visible from below wants attention within a week
- Check the flashing around chimneys and where roofs meet walls — lifted or split lead lets water straight in
- Keep trees near the roof cut back — branches abrading tiles and dropping debris shortens roof life dramatically
- If you see a stain appearing on an upstairs ceiling, call us that week — not next month
