Protect Your Property...
Help prevent wind-driven rain from leaking through the roof deck, or melting ice and snow (caused by ice dams in harsh winter climates) from leaking into property’s interior
Add Extra Protection...
In valleys and at eave and rake edges — the most leak-prone areas of the roof. Strongly recommended for chronic problem areas like skylights, dormers, vent pipes, chimneys, and other flashing areas
Won’t Leak...
Helps ensure a 100% watertight seal
Avoid Costly Repairs...
Due to staining on interior walls and ceilings
Better Appearance...
Fiberglass reinforcement helps resist wrinkling and buckling — lays flatter under shingles
Saves Labor...
Split-back release film peels off in sections, for faster installation and superior property owner value
Peace Of Mind...
