What flat roof work do we do in Carrickfergus?

Flat roof replacement

Selling or letting a property in Carrickfergus can also prompt a replacement. A buyer's surveyor will usually flag a flat roof near the end of its life, and a recent replacement with written workmanship and material guarantees answers that question before it turns into a negotiation point.

Flats, HMOs and block roofs

A block roof in Carrickfergus is a long-term asset, so we talk about whole-life cost as well as the price today. A longer-life system with corrected falls can mean fewer reactive repairs and fewer rounds of consultation over the years, and the survey explains the options in plain terms.

Extension and kitchen roofs

Condensation drives some replacements in Carrickfergus. Older extension roofs were often built cold, with insulation between the joists and no reliable vapour control. Warm air from the kitchen reaches the cold deck, moisture builds up and the timber suffers. A warm roof deals with the cause, not just the stain.
