What flat roof work do we do in Holywood?
Balconies and roof terraces
Balcony membranes in Holywood wear out like any roof, but faster where they are exposed to foot traffic, furniture and planters. Once the topcoat has worn through or cracked around posts and edges, a full re-waterproofing usually lasts longer than repeated patching.
Garage roofs
Water from a failing garage roof in Holywood does not always stay in the garage. On an attached garage it can run down the house wall or track under the flashing, and a blocked or broken gutter can spill onto the drive or a neighbour's property. Replacing the roof deals with the source.
Flat roof repairs
Older flat roofs in Holywood, as elsewhere, are often covered in felt that has lost its chippings and dried out. One leak on a roof like that is a warning sign. We repair it, check the rest of the covering and tell you honestly whether replacement belongs in next year's budget.

What flat roofs are typical in and around Holywood?
In a town like Holywood flat roofs are mostly on 1960s and 1970s link-detached houses with flat-roofed garages and porches and newer estates where the first extension roofs are now being replaced. Weather matters on a flat roof. 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.
Who approves flat roof work in Holywood?
Where approval is needed it goes to Ards and North Down Borough Council building control. In Northern Ireland, renovating or replacing a roof over a heated room usually means meeting Technical Booklet F1, and building control should be contacted before work starts. How the rules work.
