Dormer roofs in Ballymoney

We replace dormer roofs on loft conversions and older houses in Ballymoney. Small roofs at height reward careful work, so each job uses proper scaffold, a warm-roof build-up and new edge details. You get the scaffold cost in the quote, not as an extra once the job is under way.

What does a dormer roof in Ballymoney need?

High, exposed dormers in Ballymoney take the full force of the wind and rain. Edge trims loosen, flashings lift and the felt at the drip edge cracks. Once the faults spread around the perimeter, a new roof with fresh trims usually lasts far longer than another round of repairs.

In and around Ballymoney, flat roofs are typically found on 1960s and 1970s link-detached houses with flat-roofed garages and porches, and on newer estates where the first extension roofs are now being replaced. 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.

Is GRP or EPDM better on a dormer roof?

GRP fibreglass is often the first choice on a dormer, because it is laid as a liquid resin over a mat and forms neat, rigid edges, corners and drip details on a small roof. It cures to a hard surface that copes with occasional foot traffic during window cleaning or maintenance.

EPDM rubber works well on a plain rectangular dormer and can usually be laid as one sheet, with no field joins. Unlike GRP, it does not depend on resin curing conditions on the day. Torch-on felt can be used, but working a torch close to timber cladding, fascias and tiles needs extra care, so a cold-applied system is often chosen instead.

We recommend the system after surveying the dormer, its edges and how it meets the main roof.

Building control in Northern Ireland

In Northern Ireland, Technical Booklet F1 sets roof insulation at 0.18 W/m²K when a roof over a heated room is renovated or newly built, where that's feasible. The district council's building control should be contacted before work starts, and we prepare the details it asks for. More on the rules.

Can a dormer roof be replaced without scaffold?

Rarely. A tower or full scaffold is usually needed to give a safe working platform and edge protection at that height.

Not by as much as the size suggests. Scaffold and the extra detailing at height mean a small dormer roof often costs about the same as a single garage roof.
