Gaf Tpo Roof Failures

A recent study of everguard tpo roofs installed between 8 and 16 years ago found the all performed above astm standards for newly manufactured tpo.

Gaf tpo roof failures.

Fwiw we ve never observed such a failure in gaf s everguard tpo membrane what about the allan buick bers 2011 study on the roofs at unlv in las vegas that found high heat related failures of a 3 year old gaf tpo roof that resulted in replacement only 3 years later 2008 with a gaf tpo that was also failing only 2 5 years later. The second best performing class of membranes were gaf everguard tpo and firestone tpo which failed at 112 days and 105 days respectively. A recent study of everguard tpo roofs installed between 8 and 16 years ago found they all performed above astm standards for newly manufactured tpo. Gaf tpo roofing membranes include.

One of the major issues with tpo roofs has been premature aging and seam failures due to prolonged exposure to intense heat. At 1 66 per square foot generic tpo is 13 more expensive than high quality brand name pvc so the price war is lost. See page 9 top chart in sri executive summary. Tpo heat aging proposed specification failure.

Now tpo is more like epdm rubber with heat welded field seams. Gaf analyzed membrane samples from roofs across the us and studied thickness over scrim surface cracking and the ability to repair aging tpo membranes. It s no longer a truly heat welded system but is a hybrid of welded plus glued roof. Membrane failures were particularly frequent in the states that experience the most heat and uv radiation all year round.

Roofing shingles and materials plus factory certified roofers including ratings from real homeowners from north america s largest roofing manufacturer.

Gaf analyzed membrane samples from roofs across the us and studied thickness over scrim surface cracking and the ability to repair aging tpo membranes. Tpo also lost its competitive advantage by using peel stick flashing.

Gaf analyzed membrane samples from roofs across the us and studied thickness over scrim surface cracking and the ability to repair aging tpo membranes. Field failure has not occurred due to mechanical performance leaks are always the failure cracks or erosion. A recent study of everguard tpo roofs installed between 8 and 16 years ago found they all performed above astm standards for newly manufactured tpo.
