Flat roof waterproofing
Flat roofs on extensions, dormers and garages are the most common source of roof leaks. We repair and replace flat roofs in felt, EPDM rubber and GRP fibreglass. See our flat roofing page. The Planning Portal says that in most situations, re-roofing needs building regulations approval. We'll explain what applies to your roof.
Flashing and leadwork
Wherever the roof meets a wall, a chimney or a roof window, flashing keeps water out. When it lifts or cracks, water runs straight in. See our leadwork page.
Damp from the roof, or something else?
Not all damp comes from the roof. Condensation, rising damp and plumbing leaks can look similar. Damp near the top of a wall or on a ceiling, that gets worse after rain, often points to the roof, gutters or chimney. We'll tell you if we think the cause isn't the roof, so you don't pay for roofing work you don't need. See our roof leak repairs page for how we trace leaks.
