What flat roof work do we do in Coleraine?

Flat roof repairs

Flat roofs in Coleraine face the same enemies as anywhere else: rain driven against walls, leaves blocking outlets, sun drying out older felt and frost opening small cracks. People tend to notice when a stain appears on a ceiling after a storm, or when water is still sitting on the roof days after rain.

Single-ply membrane roofing

On exposed sites in Coleraine and elsewhere, mechanically fixed single-ply is specified with a fixing pattern based on wind uplift, with extra fasteners at corners and edges. That makes it a strong option for commercial roofs where wind loads are a concern.

Balconies and roof terraces

Door thresholds are a common reason for balcony work in Coleraine. Where a door was fitted with a low step-out and no drainage channel, water driven against the frame finds its way under the sill. Re-waterproofing gives the chance to rebuild that detail properly.

What flat roofs are typical in and around Coleraine?

In a town like Coleraine flat roofs are mostly on 1960s and 1970s link-detached houses with flat-roofed garages and porches and bungalows with flat-roofed side extensions and dormers. Local weather shapes the specification. Northern Ireland averages roughly 1,150 mm of rain a year, spread over many wet days, so a roof that sheds water quickly to clear outlets lasts far longer than one that holds puddles. Approximate 1991–2020 regional averages based on Met Office data.
