What should you do about a roof leak in Hammersmith and Fulham?
In Hammersmith and Fulham, as elsewhere, many flat roofs sit over rooms that matter: kitchens, bedrooms, shops and offices. A sudden leak can damage ceilings, flooring and stock within hours, which is why getting the roof temporarily weathertight comes first and the permanent fix follows.
In and around Hammersmith and Fulham, flat roofs are typically found on Victorian and Edwardian terraces with flat-roofed back additions, and on mansion blocks and purpose-built flats with large flat roofs. 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.
What's included?

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.

Can you repair a flat roof in the rain?

What causes a sudden flat roof leak?
Common causes are storm damage that lifts seams, edges or trims, outlets blocked by leaves so water backs up over upstands, and old felt cracking after a cold snap. Sometimes the cause is a wall or coping above the roof rather than the roof itself.
