Edge trims, outlets and drainage across Moray

If your flat roof in Moray has lifted trims, a rotting fascia, overflowing gutters or water that won't drain away, it's worth having the edges and drainage looked at before the problem reaches the inside of the building. We'll tell you whether a targeted repair will do, or whether the roof needs more.

Which flat roofs are common in Moray?

Flat roofs in Moray sit on newer estates where the first extension roofs are now being replaced, terraced streets with flat-roofed rear kitchens and bathrooms and shops with flat-roofed rear stores below flats. 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 Moray the application goes to Moray 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.

Why does water sit on my flat roof?

Water sits on a flat roof because it can't drain off fast enough: the falls are too shallow, part of the roof slopes the wrong way, the deck has sagged between joists, or an outlet is blocked or set too high.

Current guidance on flat roof design (BS 6229) means most roofs need to achieve a finished fall of at least 1:80, and roofs are commonly designed with a steeper fall, such as 1:60, so that building tolerances and deck deflection still leave enough slope. Many older roofs were built with less, or have settled over time.

A small amount of water that clears within a day or two of rain is often tolerable. Deeper ponding that lingers adds weight, holds dirt and debris, can shorten the life of some coverings and turns any small defect into a leak. A patch won't fix it, because the problem is the shape of the roof. The fix is to correct the falls, either with firring pieces under a new deck or with tapered insulation in a warm roof, or to add or lower outlets so water has somewhere to go. Our ponding water guide explains this in more detail.

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.

What's the difference between a drip trim and an edge trim?

An edge trim finishes the edge of the roof and holds the waterproofing down. A drip trim has a profile that throws water clear into the gutter. On many roofs a single trim does both jobs.

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.
