Composition Roof Replacement Greater Seattle Roofsmart

We Install The “Big 3” Composition Roofing Brands
In Greater Seattle

Owens Corning. GAF. CertainTeed. We’ve Got Them All…
And The Experts To Help You Pick The Right One.


When it comes to composition roof installation, we do things a little differently from most Greater Seattle roofers. Instead of forcing you to buy one brand, we offer the industry’s Big 3: Owens Corning, CertainTeed, and GAF.

Why does that matter? Aren’t all composition roofing brands basically the same?

Yes and no.

There are plenty—and we mean plenty—of low-quality roofing brands out there. The kind that fails fast and just doesn’t last.

Those are the brands we DON’T offer.

The ones we do offer share all the features you want from your new roof: robust warranties, premium leak protection, amazing style, and more. There are, however, certain key differences among the individual products these brands offer that may make one better for your tastes and needs. We perform our SmartMatch™ Needs Analysis during your free quote to determine which to recommend for YOUR home, and why.

Bottom line: The last thing we want to do is restrict your choices and give you anything less than EXACTLY what you want. We believe you should have OPTIONS—and that’s precisely what we offer.

After all…

It’s your roof. It’s your money. It’s your home. Therefore, it’s your RIGHT to get the best possible solution for your roof replacement project. It all starts with expert advice from an egghead.

Owens Corning Total Protection Roofing System Greater Seattle Roofsmart

Owens Corning® Composition Roofing

Total Protection Roofing System™

Owens Corning’s Total Protection Roofing System offers Greater Seattle homeowners stunning beauty and incredible warranty protection. Owens Corning breaks down their roofing system into four categories:

#1: Seal

This two-part protection helps keep moisture away from your roof deck and consists of the following:

  • Ice & Water Barrier: Prevents damage associated with rain, ice dams, and shingle blow-off.
  • Synthetic Underlayment: A water-shedding barrier that guards against damage from wind-driven rain.
#2: Defend

Owens Corning shingles add a strong yet beautiful layer of defense to your home. The Total Protection Roofing System is comprised of three types of shingles:

  • Starter Shingles: These lock your primary shingles in place and ensure an effective seal along the eaves and rakes.
  • Shingles: Owens Corning offers a wide-ranging selection of beautiful shingles, including the popular TruDefinition® line.
  • Hip & Ridge Shingles: These shingles protect areas vulnerable to high winds WHILE adding stylish dimension to your roof.
#3: Breathe

Attic ventilation is vitally important, and Owens Corning treats it that way by offering top-quality ventilation solutions:

  • Intake Ventilation: Appropriate ventilation helps create a balanced flow where warm, humid air is constantly replaced by cool, dry air.
  • Exhaust Ventilation: This helps manage attic temperature and humidity to protect the components of your roof from heat and moisture damage.
#4: Comfort
Owens Corning offers several blow-in insulation options to increase the efficiency and comfort of your home. These attic insulation options meet current Department of Energy standards and can help you save big dollars on your energy bills.

Composition Roofing FAQ

Q: Why Do You Offer Multiple Composition Roofing Brands?
A: Because there is no “one size fits all” roofing solution that’s right for every homeowner. So instead of offering just one brand like most roofers, we offer the top three: Owens Corning, CertainTeed, and GAF.
Q: What, Exactly, Is A Composition Roofing Shingle?

A: It’s a type of roofing that goes by many names. If you want the geeky, technical term, it’s an architectural, asphalt composition roofing shingle with laminated fiberglass layers.

That’s a mouthful, so people typically use pieces of this description when talking about composition roofing. These names you probably do recognize:

  • Asphalt shingle roofing
  • Architectural shingle roofing
  • Laminated shingle roofing
  • Fiberglass shingle roofing

TomAYto. TomAHto. Whatever you want to call it, the important thing is choosing a quality BRAND of composition shingle roofing… and having it installed by passionate experts.

Q: What Is The BEST Roofing Brand: Owens Corning, CertainTeed, Or GAF?

A: Whichever one best matches your tastes and needs, competently installed. It’s really that simple.

The truth is that you CANNOT go wrong with any of these brands. We offer them all because, while they’re all top quality, each one has its own specific strengths and style. During your free consultation, we’ll perform our SmartMatch™ Needs Analysis to pinpoint the optimal solution for YOUR home.

Q: What Kind Of Warranties Do Composition Roofs Have?
A: The brands we offer carry the best warranty protection in the country. Our premium options boast warranties of 50 years… and some are even valid for a LIFETIME.
Q: Is There A Price Difference Among Owens Corning, GAF, And CertainTeed?
A: All three are priced roughly the same—within about 10% of each other. Since these brands have different lines of shingles and products, the actual cost is more so determined by the quality level of all the other components of your design, that with us, you choose.
Q: Why Choose RoofSmart For Composition Roofing Installation?
A: We’re the Greater Seattle roofing company that does more than install pretty new shingles. We go “under the hood” to check for —and fix—any hidden issues that many roofers miss.
