Edge trims, outlets and drainage across North Yorkshire

Across North Yorkshire, ponding on flat roofs is usually caused by shallow falls, a sagging deck or outlets that are blocked or set too high. A patch won't fix that. We explain whether new outlets will help or whether the falls need correcting with firring or tapered insulation as part of a replacement.

Which flat roofs are common in North Yorkshire?

Flat roofs in North Yorkshire sit on newer estates where the first extension roofs are now being replaced, 1960s and 1970s link-detached houses with flat-roofed garages and porches and bungalows with flat-roofed side extensions and dormers. England averages roughly 870 mm of rain a year; the Pennine side of Yorkshire is wetter and windier than the east, so we specify for the site rather than the county. 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 North Yorkshire the application goes to City of York Council, Middlesbrough Council, North Yorkshire Council and 2 other councils. 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.

How long do flat roof trims and outlets last?

Properly fixed GRP or aluminium trims and well-installed outlets should last about as long as the waterproofing they are part of. What shortens their life is poor fixing, movement in a rotten deck edge and blockages that are never cleared.

A quick check of outlets and gutters each autumn, and again after storms, prevents most drainage problems. Look for leaves and silt in outlets, gutters pulling away from the fascia, trims that have lifted or split at joints and staining on the wall below the edge. The maintenance guide lists what to check and when. Only check what you can see safely from the ground, a window or a ladder at the edge, and never walk on a roof that isn't designed for it.

It depends on where the roof is: in North Yorkshire that's City of York Council, Middlesbrough Council, North Yorkshire Council and 2 other councils. 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.

Do new trims need building regulations approval?

Not usually on their own. Approval only becomes a question if the work is part of a larger re-roofing job or alters the structure.

Can a flat roof be re-laid with better falls?

Yes, as part of a replacement. Falls are corrected with tapered firring pieces under a new deck or with tapered insulation in a warm roof build-up.

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.
