What flat roof work do we do in Hemel Hempstead?

Garage roofs

Garage roofs in Hemel Hempstead 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.

Flat roof replacement

Selling or letting a property in Hemel Hempstead can also prompt a replacement. A buyer's surveyor will usually flag a flat roof near the end of its life, and a recent replacement with written workmanship and material guarantees answers that question before it turns into a negotiation point.

Warm roof insulation upgrades

Kitchen extensions in Hemel Hempstead, 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.
