Flat Roofing Essex FAQs
What types of flat roof do you install in Essex?
We install and repair all the main flat roofing systems, including GRP fibreglass (a seamless, extremely durable finish ideal for extensions and garages), high-performance felt, and liquid-applied coatings. We assess your roof, explain the options honestly, and recommend the right system for your property and budget.
How long does a flat roof last?
It depends on the system. A properly installed GRP fibreglass flat roof can last several decades because it has no seams to fail, while modern high-performance felt systems also deliver long service life when installed correctly. All our work comes with a solid guarantee for complete peace of mind.
Do you repair flat roofs as well as install new ones?
Yes. From persistent ponding and leaks to failed joints and blistering, we diagnose the fault and carry out the repair properly. If a repair is genuinely all your roof needs we will say so; if the covering has reached the end of its life we will quote honestly for a full replacement.
Which areas of Essex do you cover for flat roofing?
We are based in Chelmsford and cover the whole of Essex plus London, working within roughly a 50-mile radius of Chelmsford. That includes Brentwood, Basildon, Colchester, Braintree, Billericay, Epping and the surrounding towns, as well as London boroughs.
