What should you do about a roof leak in Hillingdon?
Flat roofs in Hillingdon, as elsewhere, often fail during the first heavy storm of autumn or after a hard frost, when an old seam finally opens. That is often when people find water running down a wall or through a light fitting, and a temporary repair is needed quickly.
In a town like Hillingdon, flat roofs are commonly found on kitchen extensions and roof terraces behind period houses or mansard and dormer loft conversions. The Thames basin is one of the drier parts of Britain at roughly 730 mm of rain a year, but summer heat is the bigger test here: dark membranes on south-facing roofs swing a long way in temperature.

How long does a temporary repair last?
A temporary repair is designed to hold for days or weeks, not years. It buys time for the roof to dry and for the permanent work to be planned.
Temporary sheeting can be lifted by high winds, and a cold-weather seal on a wet surface won't bond as well as a proper repair. We recommend booking the permanent repair or replacement promptly rather than relying on the temporary fix through a season. If the temporary work moves or the leak returns, call us again.
Once the permanent work is done, how long it lasts depends on the repair and on the rest of the roof. Our lifespan guide gives typical service lives for each roof system.

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.

Why can't you give me an exact arrival time?
Because we would rather not promise a time we can't keep. Demand spikes after storms and safe working depends on the weather, so we send a team as soon as one is available and keep you updated.
Can you repair a flat roof in the rain?
A temporary repair can often be made in wet weather if it is safe to work. A permanent repair needs a dry surface for the materials to bond, so it is done once conditions allow.
