Torch On Felt Roofing in Sittingbourne , Kent

When installed correctly by professionals, a high-performance 3-layer bitumen felt system can last 20 to 25 years. In coastal areas like Whitstable and Margate, the key to longevity is the mineral cap sheet, which protects the roof from UV rays and salt corrosion. Regular maintenance, such as keeping gutters clear and removing moss, will also help extend the life of the roof.

Yes, it is one of the best options for garages. It is more durable than traditional "pour and roll" felt and more cost-effective than some modern membranes. Because it is fused to the roof, it provides excellent protection for garages that are detached and exposed to the wind.

While it is sometimes possible to add a new layer over old felt, we generally advise against it if the original roof is failing. Overlaying can trap moisture in the old timber deck, leading to rot that stays hidden until the roof becomes structurally unsafe. We prefer to strip the roof back to the boards to ensure the foundation is solid before we install the new 3-layer system.

If we are only carrying out a minor repair to a small area, you usually do not need to upgrade the insulation. However, if we are replacing more than 25% of the roof area, Building Regulations require us to bring the thermal insulation up to current standards. We can talk you through the best way to do this while we are providing your quote.

When installed correctly using a high-quality 3-layer system, you can expect a torch on felt roof to last between 15 and 25 years. The mineral cap sheet provides excellent protection against the sun and salt spray, which are common issues for flat roofs in Whitstable and Margate. Regular maintenance, like keeping gutters clear and checking for debris, helps maximise this lifespan.

Torch-on felt is often the most budget-friendly option while still being incredibly durable. While GRP fibreglass is seamless and EPDM rubber is very flexible, a 3-layer bitumen felt system is much thicker and more resistant to impact. It has been a "tried and tested" method for decades in the UK, making it a reliable choice for most domestic garages and extensions.

We cannot install torch-on felt during heavy rain because the heat from the torch won't bond the bitumen to a wet surface. However, if you have an emergency leak, we provide 24/7 emergency cover. We can arrive quickly to install a temporary waterproof cover or tarpaulin to stop the water ingress, then return when the weather is dry to carry out a permanent, high-quality repair.

It depends on the condition of the timber. When we strip the old felt, we inspect the decking. If the boards are "spongy," rotting, or water-damaged, we recommend replacing them with new OSB3 or plywood. Laying new felt over rotten wood is a waste of money as the roof won't be structurally sound. We will always give you a clear price for any timber work before we start.
