Looking for an economical, yet attractive solution for your low-slope or flat roof?

GAF’s LIBERTY™ SBS Self-Adhering Roofing System is designed to provide exceptional protection for low-slope roofs and still complement the rest of your home’s shingled roof areas.

It’s also one of the easiest and safest solutions available for low-slope roofs. Other low-slope roofing systems require special tools, torches, open flames, hot asphalt or toxic, solvent-based adhesives. But LIBERTY™ Roofing Systems are applied without torches, open flames, hot asphalt, or messy solvent-based adhesives.

That means they’re easy to install, even by a small roofing crew. And you don’t need bulky equipment like hot tar kettles cluttering up your driveway and smelling up your home.

The LIBERTY™ SBS Self-Adhering Roofing System has earned the prestigious Good Housekeeping Seal in the US.

With warranties available for up to 20 years and the Roofsimple quality and care we offer on all our systems, you can rest knowing that your roof will protect your home for years to come.

Aluminum Drip Edge

The drip edge is often seen as less important than other components of a roof. But the truth is, it’s key to extending your roof’s life.

The natural surface tension of water causes it to cling to the shingles at the edge of the roof and run back up under the shingles — or on to the facia board. The drip edge forces water to cling to the flashing instead, then directs the water down and away from the edge of the roof.

Drip edges also protect the roof from wind and wind-driven rain.

An F4 aluminum drip edge refers to the style and size of the flashing. Many roofers use type C flashing which may not extend as far up the roof under the shingles or as far down the face of the facia board. The style of the flashing also makes a difference.

Though not as pronounced as a type F5, the type F4 still has a longer leading edge than most other flashing commonly used. This means the drip edge itself is further away from the facia board creating a more effective drip edge and protecting the roof and facia board more completely.

Why aluminum?

Many roofers still use galvanized drip edges because they’re less expensive, but aluminum is far less prone to corrosion and creates a smoother finish as well.

Our Liberty SBS Self-Adhering Roofing System includes all-aluminum drip edges, adding to the longevity and the protection of your roof.

Pipe Collars

Water penetration is one of the most destructive forces a roof has to defend against. Several areas of a roof are prone to leaks, and vent pipes are among those.

Stack pipes, or “vent stacks,” are the pipes leading from the waste pipes to the outside of the building, often going through the roof. These pipes allow the sewer gases to escape to the outside. But they also present a leak hazard.

Since the pipes penetrate the surface of the roof, extra protection is needed to ensure water won’t enter the home through the hole created for the pipe.

Pipe collars, or pipe sleeves, are a type of flashing created especially for vent pipes.
