On this page, you can learn about various roof types and materials. Over time, the elements attack roof components and accelerate deterioration. Initially, most of the deterioration is superficial but as time goes on, various roof components such as capsheets, flashings, penetration seals, drains and others begin to fail. The elements are then allowed to directly attack the roof membrane, seams, seals, mastic and other critical weatherproofing components. If this process is not controlled, premature roof failure and costly replacement are inevitable.By performing necessary maintenance and renewing damaged roof elements, the roof can be revitalized and perform like new for many years. Most weathered roof surfaces can also be upgraded with energy star, fluid-applied systems to conserve energy costs.
Below is a listing and brief description of the most common roof categories.
Thermoset MembranesThese roofs are “rubberlike” and are actually made of large pieces of synthetic rubber. When welded together, the rubber pieces are chemically bonded, forming a single-layer membrane. When stretched, they will elongate, but will return to their original shape when released. Included in this category are the following types of membranes:EPDM (Ethylene Propylene Diene Monomer)- lifespan = 12-15 yearsHypalon (CSPE)- lifespan = 15-20 years
