What flat roof work do we do in Bodmin?
Flat roof replacement
A flat roof in Bodmin is often worth replacing because it is the weak point of the building: heat escapes through an uninsulated deck, rooms below are cold in winter and hot in summer, and condensation marks the ceiling. A warm-roof replacement deals with comfort as well as leaks, so it is worth considering before the roof fails outright.
Extension and kitchen roofs
Ponding against the house wall is a common reason for replacing an extension roof in Bodmin. When the deck dips near the wall or the fall runs the wrong way, water sits against the abutment and eventually gets in. A new roof with corrected falls moves the water to the gutter.
GRP fibreglass roofing
If a flat roof in Bodmin has already been patched with fibreglass that keeps cracking, a full GRP replacement on a new, properly fixed deck often solves the problem. Cracks usually come from movement in the boards beneath, so renewing the deck and reinforcing the joints deals with the cause.

The South West averages roughly 1,260 mm of rain a year and many roofs face wind off the Atlantic, so we specify fixings and edge details for wind uplift as well as drainage. Approximate 1991–2020 regional averages based on Met Office data.
Who approves flat roof work in Bodmin?
Where approval is needed it goes to Cornwall Council building control, or a registered building control approver. Replacing more than half of a roof over a heated room usually counts as renovating a thermal element, so it is insulated to current standards and notified to building control. How the rules work.
