FAQs on LIBERTY™ roll roofing
The LIBERTY™ SBS Self-Adhering Roofing System applies quickly thanks to its convenient peel-and-stick components — meaning it applies without torches, open flames, or hot asphalt. Plus, when installed as a complete 2-ply system, it passes UL 2218A Class 4 impact-resistance testing.
The LIBERTY™ SBS Self-Adhering Roofing System consists of:
- LIBERTY™ Asphalt Primer, providing a strong foundation that promotes adhesion
- LIBERTY™ Self-Adhering Base/Ply Sheets, the first layer of protection designed for use as a waterproofing membrane
- LIBERTY™ Flashing Cement, providing excellent bonding strength along end laps, perimeter edges, penetration flashings, and metal-edge flashing
- LIBERTY™ Self-Adhering Cap Sheets, an SBS-modified, granule surfaced roofing membrane
The LIBERTY™ SBS Self-Adhering Roofing System is easy to install, making it a great choice for both homeowners and contractors who want quick and convenient protection for their low-slope roof with slopes between 1/4:12 and 3:12 without sacrificing durability or aesthetics.1
First, inspect the roof deck for any signs of needed repair. Then, brush or roll on the LIBERTY™ Asphalt Primer to help strengthen the bond between the roof deck and the LIBERTY™ Self-Adhering Base/Ply Sheet.
Cut the base/ply sheet into 7–10 foot sections before cutting the first layer in half lengthwise. Starting at the low point of the roof, lay it down, overlapping 6 inches at the ends. Hold the membrane, peel the edge of the liner, and press that down onto the deck. Then, just pull down the line to release the film.
After, use your trowel to apply Liberty Flashing Cement to the base sheet where the metal will sit. Lay the metal into place, overlapping the metal edge by about two inches. Fasten the metal with two rows of nails, staggered four inches on center. But don’t nail through your overlaps. Keep those clean.
Next, cut the LIBERTY™ Self-Adhering Cap Sheet—7 to 10-foot lengths. Just remember in order to have proper stagger, offset end laps by a minimum of 36 inches. Starting at the low point again, line the cap sheet up with the edge metal, with the selvage edge at the high side of the roof. Then, just like our Base Sheet, fold the top half back, peel off the release film—just the top half—and roll it down.
