Polymeric Rubber
Polymeric rubber is a synthetic mix of EPDM (rubber) and TPO (plastic), so this type of roofing material is generally classified as a rubber/plastic mix. These products were first offered in the 1990s, and they have enjoyed relatively positive publicity since their introduction, leading to an increase in the number of structures being roofed or re-roofed with this material.
The advantages of polymeric rubber roof systems include UL 2218 Class IV impact resistance, quick installation, limited warranties up to 50 years, wide variety of choices, UL class “A” fire rating available, UL Wind Rating up to 80 miles per hour, durability, and lighter weight than slate.
The disadvantages of polymeric rubber roof systems include their durability as rubber and plastic compounds tend to lose their plasticity over time, their average lifespan is not last as long as slate (a frequent material polymeric rubber shingles/tiles are compared to), their non-recyclable or biodegradable nature, and the fact that their contact with conventional roofing sealants such as tar or caulk may void a warranty or accelerate the affected product’s deterioration.
Donan Engineering’s team of professional engineers has the knowledge and experience to successfully study polymeric rubber & faux material roof systems for proper installation, material defect, wear and tear, storm damage, and other potential causes of roof system failure.
