Which flat roofs are common in North Lanarkshire?
Flat roofs in North Lanarkshire sit on low-rise post-war blocks of flats, bungalows with flat-roofed side extensions and dormers and newer estates where the first extension roofs are now being replaced. 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 North Lanarkshire the application goes to North Lanarkshire Council (building standards). More on the rules.
Should I fix the edges and drainage or replace the whole roof?
Fix the edges and drainage on their own if the covering is in good condition and the deck is sound. If the covering is near the end of its life or the falls need correcting across the whole roof, it is usually better value to do everything together as part of a replacement.
Trims and outlets are bonded into the waterproofing, so replacing them means cutting into the covering around the edge. On a roof with plenty of life left, that is a worthwhile repair. On an old, brittle covering, the new detail can end up stronger than the roof around it, and correcting falls means taking the covering off anyway. Our repair or replace guide sets out how to decide.
Do flat roofs need overflows?
Roofs that drain to internal outlets or behind parapets should normally have an overflow, so that if an outlet blocks, water spills somewhere visible instead of rising over the upstands and into the building.
An overflow is usually a spout or weir set through the parapet or kerb at a level below the top of the upstands. When water runs from it, that is a sign the main outlet is blocked or overloaded. On a simple roof that drains over a drip trim into an external gutter, the open edge itself does the same job.
We look at where the water goes in heavy rain, how many outlets the roof has for its size, and whether the outlets, hoppers and downpipes are clear and properly connected. Leaf guards on outlets help on roofs near trees, as long as they are cleared regularly.

Why is my fascia rotting under a flat roof?
Usually because water is getting behind a loose or badly lapped trim, or running back under the edge because there is no proper drip. The fascia and deck edge are replaced and new trims are fitted to stop it happening again.
Can you add a new outlet to an existing flat roof?
Usually, yes. The outlet is cut in at a low point, connected to a downpipe or gutter, and the waterproofing is dressed into it with compatible materials. Whether it solves ponding depends on whether water can actually reach it.
How often should flat roof outlets be cleared?
At least once a year, ideally in autumn after the leaves fall, and more often for roofs under trees. A quick check after heavy storms is also worthwhile.
