Flat roof repairs in Letchworth Garden City

In Letchworth Garden City, as anywhere, a flat roof rarely leaks right above the stain. That is why our repairs begin by tracing the water back to where it gets in, whether that's an upstand, a lap, an outlet or a wall above the roof, before we cut back to sound material and repair it properly.

When is a repair the right answer in Letchworth Garden City?

Buying or selling a property in Letchworth Garden City with a tired flat roof? A surveyor's report may flag damp, blistering or ponding. A targeted repair can deal with an isolated defect, and where the roof is near the end of its life we will explain that clearly so the cost can be planned.

Letchworth Garden City's flat roofs are mostly on 1930s semis with flat-roofed garages and kitchen extensions, with plenty on shops with flat-roofed rear stores below flats too. The East of England is the driest part of Britain, with parts of the Anglian region around 630 mm a year, so summer heat and UV, not rainfall, do most of the ageing on a felt roof.

How much does a flat roof repair cost in Letchworth Garden City?

For Letchworth Garden City we use East of England rates: £160–£530 is the guide for a localised patch repair, VAT included. We confirm the price once we've traced the leak or seen the damage.

Localised patch repair£160–£530
Upstand or flashing repair£260–£680
Outlet or drainage repair£130–£370
Emergency temporary weatherproofing visit£190–£470

What do you check and do on a repair visit?

We inspect the whole roof, not only the spot that is leaking, and tell you what we have found before any work starts.

A typical visit covers the covering itself (splits, blisters, crazing, lost chippings and open laps), the upstands and flashings at walls, edge trims and drips, outlets and gutters, any rooflights, and how water sits on the roof after rain. Where it is safe to do so, we check the deck for soft spots. Every roof is treated as fragile until a competent person has confirmed otherwise, and edge protection goes in before anyone works near an open edge.

The repair itself means cutting back to sound material, drying the area and repairing with the same system. We clear the outlets while we are up there, because a blocked outlet is a common reason a repaired roof leaks again. What the repair covers, and what it doesn't, is set out in the written quote.

What's included?

  • Inspection of the whole roof, not just the wet patch
  • Leak path traced from the stain back to the entry point
  • Outlets and gutters cleared while we're on the roof
  • Upstands, flashings, laps and seams made good

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.
