Abstract
Over the past two decades, blistering has been the most common problem with built-up roofs. The problem is most noticeable on hot, sunny days. Given that a perfect, void-free roof cannot be laid even under ideal conditions, there are nevertheless ways to reduce blisteriing. To address some of them: dry materials should be used in dry conditions. Not just dry conditions, but warm conditions as well, because voids in asphalt tend to occur more readily when asphalt cools quickly. With regard to materials, it's a good idea to use fibrous coverboards over all cellular plastic insulation so that gases formed during application can escape.
