When is a repair the right answer in Farnham?
Buying or selling a property in Farnham with a tired flat roof? A surveyor's report may flag damp, blistering or ponding. A targeted repair can deal with an isolated defect, and where the roof is near the end of its life we will explain that clearly so the cost can be planned.
In a town like Farnham, flat roofs are commonly found on 1960s and 1970s link-detached houses with flat-roofed garages and porches or terraced streets with flat-roofed rear kitchens and bathrooms. 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 Farnham?
For Farnham we use South East rates: £170–£550 is the guide for a localised patch repair, VAT included. We confirm the price once we've traced the leak or seen the damage.
| Job | Guide price inc VAT |
|---|---|
| Localised patch repair | £170–£550 |
| Upstand or flashing repair | £280–£720 |
| Outlet or drainage repair | £130–£390 |
| Emergency temporary weatherproofing visit | £200–£500 |
| Condition survey and leak investigation | £170–£330 |
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?
- Repairs with materials compatible with your roof system
- Inspection of the whole roof, not just the wet patch
- Upstands, flashings, laps and seams made good
- Leak path traced from the stain back to the entry point
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.

How much does a flat roof repair cost in Farnham?
£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.
Do I need building regulations approval for a flat roof repair?
Not usually for a patch repair. Replacing a large part of the covering over a heated room is treated differently and can bring in the thermal upgrade rules.
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.
