Rolled AsphaltĪll of these are considered outdated by modern construction standards. – Can be punctured by a sharp object, falling tree branches, etcīuilt-up roofs are manufactured using built-up layers of either tar-saturated paper and liquid tar with gravel, asphalt, rolled asphalt, or modified bitumen.Īs the roof is installed, more and more layers are added to increase durability and longevity, hence the name “built-up”.Īmong them are: 1. – Require expensive expert installation and equipment (PVC and TPO) – Exterior penetrations, such as pipes, chimney, HVAC equipment can cause leaks without proper flashing work – Membranes that have seams are prone to leaks (EPDM) – Resistant to inclement weather: snow, ice, rain, wind, fire – DIY installs and repairs are possible for EPDM rubber – Systems with hot air welded seams (PVC and TPO) are water proof – Long lasting: high end membranes last up to 30-40 years It is typically recommended to install a membrane that is at least 50 mil thick.
The average thickness ranges from 45-90 mil. The ones most commonly used are around 10 feet. All membranes range in width from 6-18 feet. Single-ply means that there is just one layer of membrane as a waterproofing and weather surface. Each has very different formulations, durability specs and cost.
It important to know that these single ply membranes are NOT equal in quality and longevity.
