Asphalt roofing still remains the most popular choice for roof replacement in Philadelphia and New Jersey, but how do you choose a shingle that is right for your home? Today, we will look at the pluses and minuses of the two most popular shingles on the market today; Owens Corning Duration Shingles & GAF Timberline Shingles.

Before we get into the differences, let’s compare the similarities. Both shingles offer a “limited lifetime warranty” and both are dimensional shingles. Dimensional shingles are what you see on homes that have re-roofed in the past 15 years. The dimensional shingles are more durable and better looking than the flat 3-tab shingles you see on older homes.

Owens Corning Duration Shingles

TruDefinition® Duration® Shingles with patented SureNail® Technology offer a high-end, premium look, which gives your home the aesthetics you desire, at an attractive price. Available in popular colors, TruDefinition® Duration® Shingles provide:

• A Limited Lifetime Warranty (for as long as you own your home)

• 130-MPH Wind Resistance Limited Warranty

• Algae Resistance Limited Warranty

• Bold, lively contrast

• Complementary shadow lines and greater dimension


Because almost every shingle roof manufacturer offers a ‘limited lifetime warranty’ it is the consumer’s job to read the fine print. Unfortunately, these product warranties only cover material and do not cover installation, removal or disposal of faulty shingles in the event of a manufacturer defect.

To protect against this, Owens Corning offers homeowners peace-of-mind by providing a list of Owen’s Corning Platinum Preferred Contractor Philadelphia that offers the Platinum Plus Warranty, a 50 year non-prorated warranty covering both labor and materials on the entire job!

GAF Timberline Shingles

GAF was the first company to really embrace the concept that you are not just installing shingles but in actuality you are installing a roof system. That is why they also offer extended warranty coverage, GAF GOLDEN PLEDGE WARRANTY Philadelphia when you install any GAF Lifetime Shingle & At Least 5 Qualifying GAF Accessories such as TimberTex ridge shingles and they’re premium breathable underlayment DeckArmor.

  • Premium Construction… Exceptionally durable, non-asphaltic construction will not rot or become brittle (unlike conventional asphalt felts, which can disintegrate over time)

GAF Timberline Shingles are the most popular roof shingle installed in PA, NJ and DE which means they are easy to acquire and are readily available in every color.

Owens Corning Duration Shingles vs GAF Timberline Shingles: THE DECISION

In the end, you can’t go wrong with either shingle but in our opinion the BEST SHINGLE TO INSTALL in PHILADELPHIA is…Owens Corning Duration Shingles!

The final decision comes down to the fact that Owens Corning Duration Shingles offer the revolutionary SureNail Technology which increases the wind warranty and prevents loose or missing shingles in a wind storm.

Although, GAF roofing offers a Premium Roof Underlayment in Deck Armor, you experienced roofing contractor can combine the Deck Armor Underlayment with either shingle. So for the best of both worlds we recommend Owens Corning Duration Shingles with GAF Deck Armor Underlayment!
