A single-ply membrane roof consists of plastic, modified bitumen, and synthetic rubber sheeting that is laid over the roof deck, usually in a single ply.
Single-ply membrane roofing are installed in three basic ways:
- fully adhered
- mechanically attached
- loose laid with ballast
If properly installed and properly maintained, a single-ply membrane roof should last up to 15 to 20 years or more. Roof penetrations and seams are the most vulnerable parts of single-ply membrane roofing and should be carefully designed and installed. The material must also deal with ultraviolet light deterioration.
With some membrane roofing, a protective coating can be used to protect it but the coating should be reapplied periodically. Other membrane types such as PVC (Duro-Last), TPO, and EPDM (rubber) do not require coatings. Check carefully for surface degradation on an unprotected roof, fading of the coating on a protected roof and also for signs of water ponding or poor drainage.
No matter what the problem is with your membrane roof, Commonwealth Roofing has earned the title “The Roofers” and will give you solid advice on whether you need roof repair or roof replacement.
