Flat Roof Rebuilds in Torbay

Full structural solutions for failed flat roofs. We replace rotten timber and install a new 20-Year Guaranteed torch-on felt system.

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 leads to sagging, major leaks, and unsafe conditions.

Warning Signs Your Deck Has Failed:

  • A 'spongy' or 'bouncy' feeling when walking on the roof.
  • Visible sagging, dips, or pooling water that doesn't evaporate.
  • Persistent leaks in the room below, even after repairs.
  • Damp patches or mould appearing on the ceiling.

If you notice any of these signs, a simple re-cover is a false economy. 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, correctly insulated, and completely waterproof for decades to come.

1. Structural Rebuild

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

2. Insulation & Waterproofing

This is the perfect time to install high-performance insulation. We then apply a multi-layer, high-performance torch-on felt system, starting with a vapour barrier and underlay, heat-bonding each layer.

3. Mineral Cap Sheet Finish

The final layer is a thick, mineral cap sheet. This provides a durable, weatherproof, and UV-resistant finish that protects the layers below and ensures maximum longevity for your new roof.

Why Choose a Full Rebuild Over a Repair?

A rebuild is an investment in your property. It solves the root cause of the problem, rather than just covering it up.

Long-Term Peace of Mind

A re-cover on a rotten deck will fail again, often within a couple of years. A full rebuild comes with our 20-year guarantee, giving you complete confidence that the job is done right.

Structural Safety

A sagging roof is a dangerous roof. Our structural rebuild replaces all weak components, restoring the roof's strength and protecting your property and family from potential collapse.

Improve Thermal Efficiency

A rebuild is the perfect time to install modern, high-performance insulation, bringing your roof up to current building standards. This will make your home warmer and reduce your energy bills.

Increase Property Value

A brand new, fully guaranteed flat roof is a major selling point. It removes a significant worry for potential buyers and adds tangible value to your home.

The Benefits of Our Torch-On Felt

While other systems exist, we specialise in high-performance, 3-layer torch-on felt because it offers proven, long-term reliability for the Torbay climate. It's not a 'paint-on' solution; it's an industrial-grade system built to last.

  • Unbeatable Durability: The multi-layer system is thick, tough, and highly resistant to punctures and tears.
  • Seamless Bond: The torching process fuses the layers together, creating a single, monolithic waterproof membrane with no weak joints.
  • Weather Resistant: The mineral cap sheet provides excellent UV protection and is robust enough to handle coastal wind and rain without degrading.
  • Proven Technology: It's a traditional system that has been trusted by professionals for decades to protect high-value commercial and residential properties.
