How do I know if I need a full new roof or just repairs?
If the roof is leaking in multiple areas, the covering is failing across large sections, or the underlying materials (felt, battens, timbers) are deteriorating, a full replacement is often the most cost-effective long-term option. We’ll inspect the roof and give honest advice on whether repairs are suitable or if a new roof is the better solution.
