When is a repair the right answer in Winchester?

Older flat roofs in Winchester, as elsewhere, are often covered in felt that has lost its chippings and dried out. One leak on a roof like that is a warning sign. We repair it, check the rest of the covering and tell you honestly whether replacement belongs in next year's budget.

In and around Winchester, flat roofs are typically found on 1930s semis with flat-roofed garages and kitchen extensions, and on lock-up garage blocks on estates. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain.

How much does a flat roof repair cost in Winchester?

At South East guide rates, a localised patch repair comes to £170–£550 including VAT. We confirm the price once we've traced the leak or seen the damage.

How long will a flat roof repair last?

A well-made repair on a roof that is otherwise sound should last as long as the covering around it. It can't add years to the rest of the roof, though.

If your felt roof is twenty years old, a perfect patch still leaves twenty-year-old felt around it, and the next weak point will appear in its own time. That is why we give you an honest view of how much life the roof has left, so you can decide whether a repair now and a planned replacement later is better value than replacing straight away.

Simple care helps any repair last. Clearing leaves from outlets and gutters, keeping people off roofs that aren't designed for foot traffic, and looking over upstands and edges after storms all catch small problems before they reach the ceiling. Our maintenance guide lists the checks worth doing each year.

What's included?

  • Fixed price confirmed in writing before work starts

Building regulations in England

Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.

Who checks building regulations for a flat roof in Winchester?

Where the work needs approval it goes to Winchester City Council building control, or a registered building control approver. We tell you at the survey whether your job needs it and deal with the paperwork as part of the quote.

How much does a flat roof repair cost in Winchester?

£170–£550 for a localised patch repair, at South East guide rates including VAT. We confirm the price once we've traced the leak or seen the damage.

Can you repair the roof if the ceiling is already damaged?

Yes. The roof is fixed first so the ceiling can dry out, and then a plasterer or decorator can make it good. Any wet insulation within the roof should be checked, as it may need replacing.

Will a repair affect my roof's guarantee?

It can. If the roof is still under a manufacturer's material guarantee, the repair should normally use that manufacturer's products and methods, so share any guarantee paperwork with us before work starts.
