What flat roof work do we do in Gravesend?
Commercial flat roofing
A commercial re-roof in Gravesend has to fit around customers, staff and deliveries. We agree working hours, skip positions and access routes before we start, keep fire exits clear throughout, and choose a flame-free system where your site does not allow hot works near stock or occupied rooms.
Torch-on felt roofing
On larger roofs in Gravesend with poor falls, torch-on felt pairs well with tapered insulation, which builds the fall into the insulation boards. That deals with ponding properly while adding insulation, rather than patching the low spots and waiting for the next leak.
Extension and kitchen roofs
Selling a house in Gravesend with a tired extension roof can raise questions in the buyer's survey. A recent replacement, with building control sign-off where needed and written guarantees, gives a buyer confidence and removes a likely point of negotiation.

What flat roofs are typical in and around Gravesend?
In a large town like Gravesend flat roofs are mostly on bungalows with flat-roofed side extensions and dormers and newer estates where the first extension roofs are now being replaced. The climate is part of the brief. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain. Approximate 1991–2020 regional averages based on Met Office data.
Who approves flat roof work in Gravesend?
Where approval is needed it goes to Gravesham Borough 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.
