Flat roof repairs in Fareham

When is a repair the right answer in Fareham?

Landlords and managing agents in Fareham need a repair done properly once, rather than a quick fix that brings tenants back on the phone a month later. We trace the leak to its source and confirm the price in writing, so the repair can be approved and booked without guesswork.

In and around Fareham, flat roofs are typically found on newer estates where the first extension roofs are now being replaced, 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 Fareham?

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

Why does a flat roof leak in one place but drip somewhere else?

Because water rarely comes through the ceiling directly below the hole. It gets in at one point, runs along the deck, a joist or the top of the insulation, and drips wherever it finds a low spot or a gap in the ceiling.

That is why a patch over the damp patch so often fails. Before we repair anything, we work back from the stain to the likely entry point and check the usual weak spots: upstands where the roof meets a wall, flashings and cavity trays above them, laps and seams, outlets and gutters, drip trims, rooflight kerbs, and any fixings or cables that pass through the covering. The fault is frequently at an edge or a wall rather than in the middle of the roof.

Sometimes the cause isn't the roof at all. Defective pointing, a failed cavity tray or a cracked coping above the roof can let water in behind the upstand, and condensation in a cold roof can look exactly like a leak. Our guide to flat roof leaks covers these causes. If the path can't be found by inspection, a leak tracing survey is the next step.

What's included?

• Upstands, flashings, laps and seams made good
• Inspection of the whole roof, not just the wet patch
• Repairs with materials compatible with your roof system
• 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.
