Flat Roof Replacement in Costessey, Norwich - Felt Stripped, GRP and Lead Installed

A customer on Oval Road, Costessey, came to us with an ageing felt flat roof that had reached the end of its life. Felt roofs don’t last forever. Once they start to fail, the risk of water ingress climbs fast and ignoring it only ever makes the repair bill bigger.

Our team stripped the whole thing back and started fresh.

What the Job Involved

This was a full flat roof replacement from the deck up. Here’s what we did:

Stripped the old felt roof covering completely
Removed and replaced the roof boards underneath, giving the new system a solid, stable base
Installed a GRP (glass reinforced plastic) fibreglass roof system
Fitted lead flashing around the edges to create a proper waterproof seal

No shortcuts. No patching over problems.

Why GRP?

GRP fibreglass is one of the most durable flat roofing options available today. Once cured, it forms a seamless, watertight surface with no joints for water to work through. It handles the freeze-thaw cycles of a Norfolk winter far better than traditional felt, and it’s typically warrantied for 25 years or more.

For a customer who wants peace of mind, not a repeat job in five years – GRP is the right call.

The Role of Lead Flashing

The roof covering itself is only part of the picture. Where the flat roof meets a wall, chimney stack, or raised edge, you need flashing to seal the junction properly.

We used lead for this job. Lead has been the roofer’s material of choice for centuries for good reason, it’s malleable enough to follow complex shapes, durable enough to outlast the roof it’s protecting, and it creates a genuinely weatherproof seal when fitted correctly.

The Result

The customer on Oval Road now has a flat roof system built to last. Clean finish, properly drained, and fully sealed at every edge and junction.
