A lot of that work follows the county's own shape: flat roofs on the coastal bungalows of Tendring, on the post-war commuter stock nearer London, and on the extensions behind the market-town cottages inland.

Flat Roofs Built
To Shed Water.
A flat roof is only as good as its details: the falls, the trims, the outlets and the joints. Cousins Roofing Contractors bring generational experience to every flat roofing job in Essex, so your extension, garage or dormer stays dry for the long term, not just until the next downpour. Essex flat roofs follow the county's spread.
The bungalows at Clacton and Frinton on the Tendring coast were built with flat-roofed garages and porches that take the North Sea weather head on, the post-war estates of Harlow bring their own flat-roofed stock, and the market towns like Maldon and Saffron Walden mix period buildings with modern extensions.

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.
