Flat Roof Repair: Do You Really Need It?

Not every failing flat roof needs replacing. On Winchester extensions a targeted repair often buys years — here is how to tell repair from replacement. Compton’s housing and setting mean some faults show up here more than elsewhere.

When it is not the answer: 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."

Anne T. · Winnall, Winchester

Our Process in Compton

How Flat Roof Repair Works in Compton

Survey confirms repair vs replace. Deck condition is assessed before quoting — rotten deck requires replacement before membrane repair or the failure repeats within 2–5 years. In Compton, the highest chalk escarpment wind exposure in coverage area means flat roof repair specifications are applied with an understanding of the Victorian farmhouse and modern infill housing stock.

The process

How a Compton Flat Roof Repair Job Runs

1. Free survey

A proper survey covers all elevations plus the loft — felt, daylight and timber — so we find where the water actually enters. Local knowledge of Compton — its streets and its housing stock — informs every survey.

2. Written quote

Afterwards, fixed price for the repair, within 48 hours.

3. Scheduling

We agree a firm date — usually within the week, and same-day for emergencies.

4. The work

On the day, localised membrane repair, flashing renewal or upstand re-dressing on a clean dry deck.

5. Cleanup & guarantee

Debris cleared, workmanship guaranteed.

Timescales

How Long Does It Take?

JobTypical duration
Patch repair2–4 hours
Flashing/upstand renewalHalf a day
Multiple-detail repair1 day

GRP and liquid repairs need a dry deck; we reschedule rather than seal in moisture. In Compton we confirm the likely duration on the survey, once we have seen the access and the roof.

Access

Getting Safely onto Compton Roofs

Single-storey flat roofs are reached from a tower or ladder. Scaffold is specified for: first-floor and higher flat roofs - always itemised in your written quote, never a hidden extra, and we arrange it.

Compton is a small downland village of period and modern homes on lanes where scaffold access needs planning but pavements are rarely an issue. Pavement scaffold and skip permits go through Winchester City Council; allow a few working days on streets like Place Lane, Compton Street where space is tight.

Guarantee

The Guarantee in Plain Terms

The repaired area is guaranteed for workmanship; we are honest that a repair on an ageing roof buys time rather than a new lifespan.

If a fault appears in covered work, we come back and put it right. No quibbling, no re-charge.

Good to know

Disruption, Mess & Weather in Compton

A few hours over one room with minimal disruption and debris cleared as we go. You do not need to stay home for external work — just power and access agreed in advance.

Repairs are timed to a dry window so the patch bonds properly. Exposed chalk-down position brings wind exposure on ridges and verges.

FAQ

Flat Roof Repair Compton — Questions

Patch repair on a Compton 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 Compton survey.

Compton's Victorian farmhouse and infill 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 Compton 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 Compton 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 Compton 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 Compton — 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.
