GAF Lifetime Roofing System

There's more to a roof than just shingles; let the GAF Lifetime Roofing System protect the integrity of your home.

The GAF integrated roofing system utilizes top quality materials to shield your home from wind, rain and other elements that could cause damage and lead to costly repairs. GAF roofing is built with the quality that you can depend on and is backed by a lifetime warranty – ensuring you’re always protected. With options that suits all budgets and designs, GAF takes the hassle out of replacing your existing roof.


What is GAF?

GAF is North America’s largest manufacturer of roofing. The GAF Lifetime Roofing System offers 6 unique features to ensure your home is protected for years to come.

1  Lifetime Shingles

GAF was also the first to offer a Lifetime ltd. warranty on all its laminated shingles.** You have many great Lifetime Shingle choices, including GAF architectural Timberline® Shingles and sophisticated Designer Shingles — all manufactured with Advanced Protection® Shingle Technology.


2  Cobra® Attic Ventilation

Effective attic ventilation is critical for a long-lasting roof. It helps remove excess heat and moisture from your attic to promote energy efficiency in your home and help extend the life of your roof.


3  Roof Deck Protection

Roof Deck Protection provides an exceptionally strong, critical extra layer of protection against wind-driven rain between your shingles and your roof deck. Some even allow moisture to escape from your attic!

4  Starter Strip Shingles

Pre-cut starter strips are one of the most overlooked parts of a roofing system. They save time, eliminate waste, reduce the risk of shingle blow-off and may even help qualify for upgraded wind warranty coverage (see GAF Shingle & Accessory Ltd. Warranty for details).


5  Leak Barriers

Leak Barriers help protect the most vulnerable, leak-prone areas of your roof: valleys, eaves, and rake edges. They provide exceptional protection against leaks caused by roof settling and extreme weather.

6  Ridge Cap Shingles

The perfect finishing touch for your new roof should be a protective and distinctive ridge cap shingle. It enhances the beauty of your home while guarding against leaks at the hips and ridges.

Did You Know?

A way to prolong the life of your shingles is to install proper ventilation. Asphalt shingles should never be installed on flat roofs as it does not have a slope for water to flow away.



7 Signs you Need a New Roof

There are several reasons why you might need a new roof. If you haven’t replaced your roof in a long time, it’s likely it has been impacted by weather damage or corrosion, and may not be protected against harsh weather conditions ahead. Another reason to replace your roof is for aesthetic appeal. With a variety of stylish and innovative shingle styles and colours, a new roof is a great way to boost your curb appeal.

If you’re unsure, here are 7 signs you might need a new roof:

1  A leak in the attic.

After a strong storm or wind-driven rain, take a look in the attic for signs of leaking. Ice damming can also cause water to enter the house if you don’t have an adequate shingle underlayment or if the flashing (the aluminum or steel used over roof joints, like chimneys and pipes) has deteriorated.


2  Blistering or peeling interior or exterior paint.

When paint starts to peel off, the cause is likely trapped moisture in the house due to excessive temperature or high humidity from poor attic ventilation. The air in the attic needs to flow freely from the soffit to the ridge to reduce humidity. Make sure there is a vent in areas such as the kitchen or bathroom. Dryers should vent outside.


3  Stains on interior ceilings and walls; mold or mildew growth.

If you see stains or, even worse, mold growth inside your home, it may be caused by inadequate or faulty shingle underlayment that is allowing water to seep into the house. Inadequate ventilation could also be the culprit, which causes excessive moisture— conditions in which mold and mildew thrive.


4  Exterior decay, sheathing, and/or siding.

Poor attic ventilation is again a possible cause, but any condition that results in excess moisture can contribute to decay. One way to combat the problem is to put a vapor barrier between the insulation and the inside of the house, which can reduce the amount of moisture that goes into a wall and help the moisture escape from the wall.


5  Missing, cracked, or curled shingles.

If you see that your shingles are dry or practically break when touched, that means they have reached the end of their useful life and it’s time to invest in a new roof.


6  Dark, “dirty-looking” areas on your roof.

This could mean your roof has vegetation, fungus, mold, or algae growth, or that the shingles’ protective granules have been lost. This doesn’t mean you need to replace your roof, but these stains can reduce curb appeal. Cleaning the shingles is an option, but that could shorten their life. Fortunately, StainGuard® protection is available on many GAF Shingles, including Timberline® Cool Series Shingles, Timberline® Natural Shadow® Shingles, and Timberline® ArmorShield™ II Shingles. (StainGuard® protection is available only on shingles with StainGuard®-labeled packaging. See GAF Shingle & Accessory Ltd. Warranty for complete coverage and restrictions.)


7  Excessive energy costs.

A possible cause of higher cooling costs could be insufficient attic ventilation, requiring the cooling system to run excessively. In warm weather, inadequate ventilation will trap hot air in the attic, causing air-conditioning systems to work harder, or leaving your home’s interior hotter and less comfortable. In both hot and cold weather, moisture in the attic can become trapped and condense on the rafters if it’s not insulated properly. This moisture can drip down onto the insulation and reduce its effectiveness, potentially increasing energy costs.

Don’t Forget!

Clean up tree debris! A little leaf or a few pine needles are fine, but if they collect and are deep enough to hold moisture, they need to be taken off the roof. Anything that traps moisture will cause mildew to form, block gutters, or cause extra weight on the roof. A rake or air blower can be used to clear the roof, but take care not to damage the shingles.


* The word “Lifetime” means as long as the original individual owner of a single family detached residence (or the second owner in certain circumstances) owns the property where the shingles are installed. For owners/structures (e.g., a church) not meeting above criteria, Lifetime coverage is not applicable. See limited warranty for complete coverage and restrictions. Installer certification is only for installations covered by GAF system warranties. Maximum wind coverage requires special installation. See limited warranty for complete coverage and restrictions.
