What flat roof work do we do in Comber?

Green and sedum roofs

If you're replacing an old flat roof in Comber, it's worth deciding whether to add sedum at the same time. If the structure can take it, that is the ideal moment, because the waterproofing is new and the green layers won't need lifting for a long time.

Single-ply membrane roofing

If a flat roof in Comber has poor falls and ponding, a single-ply re-roof with tapered insulation can correct both problems at once. The tapered boards build the fall into the insulation, and the membrane is laid over the top, with outlets set at the new low points.

Flat roof replacement

Exposure matters too. Wind lifts tired edges, and repeated wetting and drying works at old joints, so roofs in exposed spots can wear faster than the same roof somewhere sheltered. Wherever your property is in Comber, a survey tells you whether the roof has years left or needs replacing now.

What flat roofs are typical in and around Comber?

In a town like Comber flat roofs are mostly on bungalows with flat-roofed side extensions and dormers and 1930s semis with flat-roofed garages and kitchen extensions. 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.
