Choosing the Right Material for Your Sussex Flat Roof
As an independent roofer handling projects across Brighton, Hove, and Worthing, I am often asked what the best material is for a flat roof. Our coastal climate demands a system that can withstand intense sun, heavy rain, and constant temperature fluctuations. Over my years in the trade, I have found that nothing performs quite like Tecnatorch SBS Torch-On Mineral Felt in Charcoal.
The Power of Flexibility: SBS Felt vs. Fiberglass
One of the biggest advantages of Tecnatorch SBS modified bitumen is its incredible ability to expand and contract seamlessly as temperatures change. Many property owners initially ask me about fiberglass (GRP) systems, assuming that because the material is extremely rigid, it must be stronger. In roofing, however, extreme rigidity is actually a major disadvantage.
Buildings naturally shift and settle. When a rigid fiberglass roof faces structural movement, it cannot flex. Instead, it tends to crack, especially in vulnerable areas like internal corners, between two opposing walls, or around penetrating cast iron pipes. SBS torch-on felt absorbs this movement without compromising the watertight seal.
Superior Puncture Resistance and Self-Healing
Other synthetic single-ply plastics and rubbers also have their drawbacks; primarily, they are relatively easy to puncture or slice. Whether it is from dropped tools, fallen branches, or heavy foot traffic, a small tear in a thin membrane can lead to a significant leak.
Tecnatorch SBS felt offers excellent thickness and durability. Even more impressively, this material has self-healing properties. Minor penetrations, such as tiny nail holes, can actually seal themselves when the dark charcoal mineral surface is exposed to the high heat of the direct summer sun.
Long-Term Value and Simple Future Repairs
A well-installed flat roof using high-performance SBS felt will easily last 25 to 30 years. What makes it truly exceptional is what happens at the end of its lifespan. Unlike fiberglass or single-ply membranes that often require a complete and costly tear-off, an aging torch-on felt roof can usually be refurbished simply by torching a new layer of felt directly over the existing one. This makes long-term maintenance incredibly straightforward and cost-effective.
