Flat Roofing in Hampton — EPDM, GRP & Felt

Modern flat roofing for extensions, garages and dormers — fully watertight and built to spec, with low-maintenance systems we'd put on our own homes.

Looking for a flat roofer in Hampton?

We install and replace EPDM rubber, GRP fibreglass and torch-on felt flat roofs on extensions, garages and dormers from our Hampton base. The right system depends on the deck, the shape of the roof and how it is used, so we look at the roof first and recommend one option in a written, itemised specification.

How we work on flat roofing jobs

Most failing flat roofs we see are let down by what sits under the covering: a soft deck, ponding caused by poor falls, or insulation that has become wet. That is why we prefer to strip back, check the deck and falls, and put in insulation to current building regulations rather than laying a new membrane over an old problem.

HRD is family-run, with 10+ years' experience and full insurance. We handle upstands, trims, outlets and any rooflights as part of the same job, so the edges — where flat roofs usually leak — are detailed by the same people who laid the main surface.

Choosing EPDM, GRP or felt

The right covering follows the roof rather than a sales preference. EPDM suits broad, simple roofs where a single sheet can minimise field joints. GRP creates a hard, seamless finish and works well around visible edges and more detailed shapes when the deck is stable and conditions are suitable for installation. Modern felt remains a practical option for awkward forms and tighter budgets.

Whichever surface is chosen, the less visible work matters just as much: the deck must be sound, the falls must lead water to the outlets, insulation must suit the build-up, and upstands and trims need enough height and careful detailing. We inspect those elements before setting out the written specification.

Frequently asked questions

Which flat roof system is best?

EPDM rubber and GRP fibreglass both offer 20+ year lifespans. We recommend the right one based on the deck, access and budget.

Can you replace a leaking flat roof?

Yes. We strip back, check the deck and insulation, and install a new fully bonded waterproof system.

How long does a flat roof last?

Modern EPDM and GRP roofs typically last 20–30+ years when installed correctly.

What should I compare in a flat-roof quote?

Compare the deck, falls, insulation, membrane or resin system, upstands, outlets, trims and guarantee. A covering price alone does not show whether the complete roof build-up has been allowed for.

Can a new covering go over the old flat roof?

Sometimes, but stripping back allows the deck, falls and insulation to be checked. Covering over trapped moisture or a soft deck carries the old problem into the new roof.

Do you repair flat roofs or only replace them?

Both. A local split, a lifted seam or a failed upstand can often be repaired. If the deck is soft or water has spread through the insulation, we explain why a strip and replacement is the better value.
