What should you do about a roof leak in Farnham?
Leaves and debris build up in outlets and gutters on flat roofs around Farnham, especially under trees. A blocked outlet can turn a normal rainstorm into a flood over the upstands. Clearing it is often part of the emergency visit, and the permanent fix looks at why it blocked.
Farnham's flat roofs are mostly on newer estates where the first extension roofs are now being replaced, with plenty on bungalows with flat-roofed side extensions and dormers too. 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.

Should the roof be repaired or replaced after an emergency leak?
It depends on what the inspection finds once the roof is dry. A single storm-damaged area on a sound roof can usually be repaired. Widespread damage, wet insulation or a soft deck point towards replacement.
Emergencies tend to happen on roofs that were already near the end of their life. A storm lifts a tired seam, or a winter of frost opens cracks in old felt. We will give you a straight answer about which applies to your roof, and our repair or replace guide explains how to weigh it up.
Water that got in during the leak needs to dry out. Saturated insulation inside a roof doesn't insulate well and can keep the deck damp, so if it is soaked, it will need replacing as part of the permanent work.

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 I put a tarpaulin on my flat roof myself?
We'd advise against it. Getting onto a flat roof in bad weather is dangerous, and many roofs and rooflights are fragile. Contain the water indoors and call us instead.
Is a leaking ceiling dangerous?
It can be. A ceiling that is bulging or sagging may be holding water and could come down, so keep people out of the room beneath it. Water near light fittings or sockets is a serious electrical risk, so isolate that circuit if you can do so safely.
