The following roof repair procedure only applies to mild to moderate alligatoring on a built up roof. Severe alligatoring will use too much product and you may be better off with other alternatives. Don't hesitate to call us for technical support.
- Thoroughly clean the roof area to be repaired. If the alligatoring is all over the roof, pressure washing is recommended.
- Small hairline cracks can be filled simply by applying EnergyGuard Aromatic Polyurethane and working it in with a roller or putty knife. For larger areas, you can embed SeamStitch Polyester Fabric into the coating and create a smoother, reinforced surface.
