As flat roofing is susceptible to water damage, this may lead to extensive repairs during rainy seasons. The top coat of a foam roof needs to be recoated every 5-10 years, as it may be susceptible to UV radiation. As single-ply roofing only has one thin layer, it can be easily punctured and may require repairs.
