Crazing

Crazing is the development of a multitude of very fine cracks on single ply membranes such as TPO and PVC. It is similar to alligatoring.

PVC Roof Crazing

This PVC roof has moderate crazing. It needs to be coated before permanent membrane damage occurs.

Crazing on single ply membranes occur on the top layer above the reinforcing mesh. If deterioration continues, the craze can become a crack which results in roof failure. Widespread crazing allows water to penetrate the membrane causing roof leaks which can be difficult to isolate and repair.

Elastomeric roof coatings can be used to restore a crazed roof in good condition. Depending on the your roofs existing condition and configuration, elastomeric roof restoration can save up to 50% over re-roofing costs. The money spent on restoration is not a capital investment and does not need to be amortized.
