Flat Roof Repair Colden Common

Honest advice

Do You Actually Need Flat Roof Repair?

Not every failing flat roof needs replacing. On Winchester extensions a targeted repair often buys years — here is how to tell repair from replacement. In Colden Common specifically, woodland-edge village where heavy tree canopy drives autumn valley and gutter blockage.

A single blister or split in an otherwise sound membrane
A localised leak traceable to one detail or upstand
A lifted edge or failed flashing at the abutment
Ponding at one low spot

Be honest with yourself: If the deck has rotted or the covering is failing in multiple places, patching is money wasted — replacement is the honest call. Read the full guide.

Customer Reviews

What Customers Say

★★★★★

"Extension flat roof had been leaking for two years. They surveyed, found a deck board that had rotted through, replaced it and applied GRP. Completely dry now."

Louise R. · Badger Farm, Winchester

★★★★★

"Previous roofer had patched with felt and charged full rates. This team replaced the full membrane in GRP with a proper warranty. Should have done it years ago."

Mark D. · Boyatt Wood, Eastleigh

★★★★★

"Good honest advice — told us repair was appropriate rather than pushing for a full replacement. Patch repair has held through two winters. Very happy."

FAQ

Flat Roof Repair Colden Common — Questions

Patch repair on a Colden Common extension flat roof: £300–£600. Torch-on felt section replacement: £400–£800. Full GRP replacement on a standard extension (20m²): £1,800–£2,800. Free survey — we confirm repair vs replace at survey and include both options in the written quote.

If failures are at one or two isolated locations and the surrounding membrane is sound, repair is appropriate. If the roof has failed at multiple points, has soft deck boards, or is over 30 years old with no previous replacement, full GRP replacement is likely better value. We confirm at the free Colden Common survey.

Colden Common's 1960s–70s woodland-edge properties typically have felt flat roofs on rear extensions added in the 1960s–80s. These membranes are now 40–65 years old — many are at or past end of design life.

GRP repairs require temperatures above 5°C and dry conditions — most Winchester winter days meet this threshold. Felt torch-on repairs can proceed in cold conditions. We monitor the forecast for Colden Common and carry out flat roof repairs on appropriate winter days.

Patch repair: 2–4 hours. Torch-on section replacement: half a day. Full GRP replacement on a standard Colden Common extension: 1–2 days. Full timelines are confirmed in the written quote.

Yes — deck condition is part of every flat roof survey. Soft deck boards require replacement before membrane repair — applying new membrane over rotten deck creates re-failure within 2–5 years. Deck replacement cost is confirmed before work starts, not discovered and charged afterwards.

GRP patch repairs: 10-year workmanship guarantee. Full GRP replacement: 25-year manufacturer warranty plus 10-year workmanship guarantee. Torch-on felt repairs: 10-year workmanship guarantee. Written guarantee issued on completion of all Colden Common flat roof work.

An active leak through a flat roof causing ceiling damage is an emergency. We provide same-day emergency flat roof response across Colden Common — call 01962 809171. We make the roof watertight in the same visit and book the permanent repair if specialist materials are required.

No — GRP requires stripping the existing membrane to a clean, dry deck. GRP applied over felt does not bond correctly and the manufacturer warranty is void. Full strip is always required for a warranted GRP installation.

We check and clear outlet drainage on every flat roof survey and repair visit. Blocked outlets are a primary cause of membrane failure — water that cannot drain ponds on the surface and accelerates deterioration. Outlet clearing is included in the survey, not a separate charge.
