Flat roof repairs in Portslade

When is a repair the right answer in Portslade?

Flat roofs in Portslade face the same enemies as anywhere else: rain driven against walls, leaves blocking outlets, sun drying out older felt and frost opening small cracks. People tend to notice when a stain appears on a ceiling after a storm, or when water is still sitting on the roof days after rain.

In and around Portslade, 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 Portslade?

Guide price in Portslade: £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.

Should I repair or replace my flat roof?

Repair it if the defect is isolated and the rest of the roof is sound, dry and still well within its working life. Replace it if leaks keep coming back, cracking or blistering is widespread, the insulation is wet or the deck feels soft underfoot.

A useful test is to ask whether a repair would still look sensible if a second leak appeared somewhere else a few months later. On a roof near the end of its life, patching one split tends to move the problem rather than solve it, and repeated call-outs soon add up to a large share of the cost of a new roof. On a roof that is a few years old with one storm-damaged lap, a repair is the right answer and we will say so.

Our repair or replace guide sets out the signs in more detail, and the lifespan guide gives typical service lives for each system.

What's included?

• Upstands, flashings, laps and seams made good
• Repairs with materials compatible with your roof system
• Inspection of the whole roof, not just the wet patch
• Outlets and gutters cleared while we're on the roof

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.
