What flat roof work do we do in Potters Bar?

Garage roofs

Garage roofs in Potters Bar take the weather head-on, often with no shelter from surrounding buildings. Wind lifts loose edge trims, frost works at cracked felt, and leaves block small gutters. When several of these faults appear together, a new roof with fresh edges is usually better value than chasing each one.

Warm roof insulation upgrades

Kitchen extensions in Potters Bar, as elsewhere, produce a lot of moisture from cooking. Under a cold flat roof, that moisture can condense on the deck. A warm roof keeps the deck warm and puts a vapour control layer in the way, which lowers the risk considerably.

Flat roof repairs

Flat roofs in Potters Bar face the same enemies as anywhere else: rain driven against walls, leaves blocking outlets, sun drying out older felt and frost opening small cracks. People tend to notice when a stain appears on a ceiling after a storm, or when water is still sitting on the roof days after rain.
