Flat Roofing in Cromer

Flat roofs on garages, extensions and commercial buildings need the right system from the outset - poor installation is the most common reason they fail early. We install and repair flat roofs across Cromer using GRP fibreglass, EPDM rubber and felt systems, all with long-term guarantees.

What's involved

How we handle flat roofing

Flat roofs have a bad reputation, and it's largely undeserved - most of the problems people associate with them come from outdated felt systems or poor installation, not the concept itself. Modern flat roofing systems, installed correctly, are reliable, low-maintenance and genuinely long-lasting.

We work with three main flat roofing systems: GRP fibreglass, EPDM rubber membrane and reinforced felt. GRP is our most commonly specified system for domestic extensions and garage roofs in Cromer - it's seamless, highly resistant to ponding water, and carries a 25-year product guarantee. EPDM is an excellent choice for larger roof areas or roofs with more complex geometry, and modern reinforced felt systems are a cost-effective option where budget is the primary concern. We'll explain the differences and match the system to your building and budget.

Flat roofing looks straightforward but the details are what determine whether it lasts. Falls need to be set correctly so water runs to the outlet rather than pooling at the low point. Upstand heights, edge trims and penetrations - for pipes, rooflights or AC units - all need to be detailed properly, or that's where water will find a way in. A flat roof installed without proper attention to these points will start leaking within a few years regardless of how good the membrane itself is.

We survey the existing deck or new structure before specifying a system, and we install all flat roofs to current BS 6229 standards. New flat roof installations typically take one to three days depending on size and complexity. All our flat roof installations come with a workmanship guarantee alongside the manufacturer product warranty.

Flat roofs in Cromer typically cost between £70 and £120 per square metre installed, depending on the system chosen and access requirements.

Questions

What people ask first.

Flat roofs in Cromer typically cost between £70 and £120 per square metre installed, so a standard single-garage roof of around 15-18 square metres would cost roughly £1,050 to £2,160. GRP fibreglass sits at the higher end of that range, reinforced felt at the lower end. We provide a free survey and written quote for all flat roofing work.
A GRP fibreglass flat roof installed to manufacturer standards typically lasts 25 years or more with minimal maintenance. EPDM rubber membranes have a similar lifespan. Traditional mineral felt has a shorter life of around 10-15 years. The biggest factor in longevity is the quality of installation - particularly correct drainage falls and properly detailed junctions.
It depends on the system and its condition. GRP and EPDM roofs can often be repaired effectively if the damage is localised - a split, a lifted edge detail or a failed penetration seal. If a felt roof is more than 15 years old and showing widespread cracking or blistering, a full replacement to a modern system is usually better value than repeated patching. We'll give you a straight assessment when we survey it.
