The lashing rain and humidity of New Zealand’s climate demand a lot of most pitched roofs. However, when it comes to flat roofs there’s another element to consider—puddling. Since gravity can’t pull the water down and away on a flat roof, the water can settle and stagnate on slightly uneven sections of the roof. This has the potential to cause severe water damage, encourages pests to infiltrate roof systems, and can cause premature roof sagging.
Typical Built Up Roof (BUR) systems consist of alternating bitumen and fabric layers to repel water, and a modified bitumen roof membrane is asphalt-based roofing cement. Both are effective, but we tend to recommend rubber roofing.
A rubber roof coating is made from rubber and a combination of other plastic polymers, typically one called ethylene propylene diene monomer (EPDM). The rubber sheet membrane is easy to install, less harmful to the environment, and more flexible than the typical asphalt system. It has many other benefits, so get in touch with the experts at Auckland Commercial Roofing to enquire about them today.
