Flat roofing specialists

Flat roofs offer a faster and simpler installation process while reducing long-term repair and maintenance costs. They provide practical space for placing air conditioning units and make solar panel installations less visible compared to sloped roofs, keeping your property looking neat and functional.

Homeowners across Bedfordshire, Buckinghamshire and Hertfordshire trust us for careful installation, strong materials, and a smooth, stress-free experience. We believe in doing the job properly the first time, with clear communication and workmanship you can rely on. As a family-run firm with over 10 years' experience, every flat roof we lay is fully guaranteed.

Flat roofing materials and options

Modern flat roofing has moved a long way beyond the old mineral felt that used to crack and blister within a few years. We work with the leading systems and will recommend the right one for your building and budget. EPDM rubber is a single-sheet membrane that is extremely durable and can last 30 years or more with very little maintenance. GRP fibreglass gives a tough, seamless finish that is ideal for dormers, porches and balconies. High-performance felt systems are torched on in layers for a reliable, cost-effective covering. Each option is fully waterproof, and we make sure the falls and drainage are right so water runs off properly rather than pooling.

Where flat roofs work best

Flat roofs suit a wide range of jobs, from garages, extensions and dormers to porches, outbuildings and larger commercial premises. They are quicker to install than a pitched roof, easier to access for maintenance, and make a tidy base for solar panels or rooflights. If you are extending your home, a flat roof can also keep ceiling heights and sightlines neat. For larger or industrial buildings, we can advise on suitable systems as part of our wider commercial roofing work, and we always make sure your guttering and outlets are matched to the new roof so rainwater is carried away cleanly.

Signs your flat roof needs attention

Flat roofs give plenty of warning before they fail if you know what to look for. Pooling or standing water that does not drain, blisters and cracks in the surface, lifted or peeling edges, damp patches on the ceiling below, and a green film of moss or algae all suggest the covering is past its best. Sometimes a targeted roof repair is all that is needed, but where the membrane has reached the end of its life a full re-cover is the sounder long-term choice. We will inspect the roof, explain what we find, and never push you towards a bigger job than you need.

FAQs

Common questions

How long does a flat roof last?

It depends on the system used. A quality EPDM rubber membrane can last 30 years or more, GRP fibreglass typically lasts 25 to 30 years, and modern felt systems give reliable service for many years. Correct installation, good drainage and occasional checks all help your flat roof reach its full lifespan.

Which flat roofing material is best?

There is no single best material, as it depends on the building, the budget and how the roof will be used. EPDM rubber is hard-wearing and low maintenance, GRP fibreglass gives a tough seamless finish ideal for smaller areas, and felt systems are a cost-effective choice. We will recommend the right option for your project after looking at the roof.

Why does water pool on my flat roof?

Flat roofs are not completely level but are built with a slight fall so rainwater drains away. Pooling usually means the falls are too shallow, the outlets are blocked, or the structure has sagged over time. Standing water shortens the life of the covering, so it is worth having it checked and corrected.

Can you put solar panels on a flat roof?

Yes, flat roofs are well suited to solar panels, which can be angled on mounting frames for the best output while staying out of sight from the ground. We make sure the roof covering is sound and properly sealed around any fixings so it stays fully watertight.
