When is a full timber deck rebuild necessary?

A full rebuild is necessary when the roof's underlying structure is compromised. This includes rotten timber joists, widespread failure of the wooden deck, or if the roof is sagging. A simple re-covering will not fix these fundamental structural problems.

What is a 3-layer torch-on system?

It's a traditional and highly reliable method of waterproofing. It involves applying three separate layers of bitumen felt using a torch to create a single, thick, and seamless waterproof membrane that is extremely durable.

When a Simple Repair Isn't Enough

Sometimes, just replacing the top layer of felt doesn't fix the real problem. Years of slow water ingress can cause the underlying timber joists and wooden deck to rot, compromising the structural integrity of your roof. This can lead to sagging, major leaks, and unsafe conditions.

A full rebuild is the only guaranteed long-term solution to restore the safety, performance, and peace of mind that your property deserves.

Our Rebuild & Waterproofing Process

We follow a meticulous process to ensure your new flat roof is structurally sound and completely waterproof.

Structural Rebuild

We strip the roof back to its joists, replace any rotten timbers, and install a solid, new 18mm OSB3 structural deck to form a robust foundation.

3-Layer Torch-On System

We apply a multi-layer, high-performance torch-on felt system. Each layer is bonded by heat to create a single, thick, and seamless waterproof membrane.
