Flat roof repairs across Highland

A repair is the right call for many flat roofs in Highland: one defect, a sound deck, dry insulation and plenty of life left in the covering. Where that isn't the case, we will say so and explain why. Either way, you'll know what you are paying for and why before anyone starts work.

Which flat roofs are common in Highland?

Flat roofs in Highland sit on lock-up garage blocks on estates, bungalows with flat-roofed side extensions and dormers and 1930s semis with flat-roofed garages and kitchen extensions. Scotland averages roughly 1,570 mm of rain a year, with the west far wetter than the east, so drainage, falls and wind uplift are part of every specification we write. Approximate 1991–2020 regional averages based on Met Office data.

Building standards in Scotland

In Scotland a building warrant is usually needed for alterations, structural work and new roofs; like-for-like repairs to a covering can be exempt. Section 6 of the technical handbooks sets a domestic roof benchmark of 0.12 W/m²K, applied as far as reasonably practicable on an existing roof. In Highland the application goes to The Highland Council (building standards). More on the rules.

Why does a flat roof leak in one place but drip somewhere else?

Because water rarely comes through the ceiling directly below the hole. It gets in at one point, runs along the deck, a joist or the top of the insulation, and drips wherever it finds a low spot or a gap in the ceiling.

That is why a patch over the damp patch so often fails. Before we repair anything, we work back from the stain to the likely entry point and check the usual weak spots: upstands where the roof meets a wall, flashings and cavity trays above them, laps and seams, outlets and gutters, drip trims, rooflight kerbs, and any fixings or cables that pass through the covering. The fault is frequently at an edge or a wall rather than in the middle of the roof.

Sometimes the cause isn't the roof at all. Defective pointing, a failed cavity tray or a cracked coping above the roof can let water in behind the upstand, and condensation in a cold roof can look exactly like a leak. Our guide to flat roof leaks covers these causes. If the path can't be found by inspection, a leak tracing survey is the next step.

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.

Which council handles building standards for a flat roof in Highland?

Who carries out the repair?

Vetted roofing teams working under S&K Property Investments and Improvement Ltd, part of the S&K Group, which is the company you contract with. The price and scope are agreed in writing before work starts.

Why does my flat roof only leak in heavy rain?

Usually because water only reaches a weak point when it builds up: a partly blocked outlet, a low spot where water ponds, or an upstand that is too low for the depth of water. Wind-driven rain against a wall above the roof is another common cause.

Can you repair the roof if the ceiling is already damaged?

Yes. The roof is fixed first so the ceiling can dry out, and then a plasterer or decorator can make it good. Any wet insulation within the roof should be checked, as it may need replacing.
