How much does a flat roof repair cost in Merseyside?

Guide prices including VAT at North West rates. We confirm the price once we've traced the leak or seen the damage.

Which flat roofs are common in Merseyside?

Flat roofs in Merseyside sit on lock-up garage blocks on estates, 1930s semis with flat-roofed garages and kitchen extensions and 1960s and 1970s link-detached houses with flat-roofed garages and porches. The North West is one of England's wetter regions, averaging roughly 1,290 mm of rain a year, so falls, outlets and well-detailed upstands matter more than the membrane colour. Approximate 1991–2020 regional averages based on Met Office data.

Building regulations in England

Replacing more than half of a roof over a heated room usually counts as renovating a thermal element, so it is insulated to current standards and notified to building control. Renovated roofs over heated rooms are insulated to around 0.16 W/m²K where that's feasible, and new extension roofs are built to 0.15 W/m²K. In Merseyside the application goes to Liverpool City Council, Wirral Council, St Helens Borough Council and 2 other councils. More on the rules.

How long will a flat roof repair last?

A well-made repair on a roof that is otherwise sound should last as long as the covering around it. It can't add years to the rest of the roof, though.

If your felt roof is twenty years old, a perfect patch still leaves twenty-year-old felt around it, and the next weak point will appear in its own time. That is why we give you an honest view of how much life the roof has left, so you can decide whether a repair now and a planned replacement later is better value than replacing straight away.

Simple care helps any repair last. Clearing leaves from outlets and gutters, keeping people off roofs that aren't designed for foot traffic, and looking over upstands and edges after storms all catch small problems before they reach the ceiling. Our maintenance guide lists the checks worth doing each year.

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.
