“Protect Your Investment And Safeguard Vulnerable Areas”

Protect Your Home From Wind-Driven Rain And Damaging Ice Dams With A Waterproof Leak Barrier

weatherwatchA Quality Leak Barrier Will:

Create a 100% watertight seal that keeps water out at the most vulnerable areas of your roof (at the eaves and rakes, in valleys, around chimneys, etc.).

Weather Watch®, a quality leak barrier, will:

  • Protect your home by preventing costly repairs due to wall or ceiling staining
  • Help prevent leaks due to water damming in your gutters, wind-driven rain, and, in the North, damaging ice dams

Weather Watch® leak barrier is a key part of the GAF Smart Choice® Roof System Solution.

Don’t Put Your Home At Risk

  • The Codes Are Clear...
    Protection against ice dams is required at eaves.
  • But Be Prepared...
    Ice dams can still occur in areas where the average temperature is above 25°F (not to mention wind-driven rain).
  • Avoid The Risks...
    If you are in an area that requires leak barrier protection–and if there is a leak– you could be putting your insurance coverage at risk by not installing it!


Protect Your home With Premium "Breathable" Roof Deck Protection

deckarmorPremium Roof Deck Protection should protect your home and “breathe” at the same time (amazingly, most so-called premium products do NOT breathe!)

It provides a critical extra layer of protection between your shingles and your roof deck — to help prevent wind-driven rain (or water from other sources) from infiltrating under your shingles and causing damage to your roof structure or to the inside of your home.

In addition, a premium quality roof deck protection will:

  • “Breathe” to allow moisture from inside your attic to escape (to help prevent structural decay, mold, and mildew)
  • Provide longer-lasting leak protection than conventional “felts” (which can rot or become brittle before your shingles reach their useful life)
  • Lay flatter so your shingles will lay flat and uniform

Deck-Armor™ Roof Deck Protection is a key part of the GAF Smart Choice® Roof System Solution

The very best roofing systems require premium, breathable roof deck protection

Deck-Armor™ Roof Deck Protection combines exceptional strength and superior breathability to help protect your home against roof rot and other costly damage!

  • Exceptionally strong: At least 600% (i.e., 7 times) greater tear strength than standard #30 felt!
  • Revolutionary “breathable” technology: Helps prevent inside moisture from becoming trapped within your roofing system—and causing mold, mildew, and expensive structural damage
  • Premium construction: Exceptionally durable, non-asphaltic construction will not rot or become brittle (unlike conventional asphalt felts which can disintegrate over time)
  • Long-Lasting Protection: Backed by a 25-year ltd. warranty against manufacturing defects
  • Looks Better: Unlike conventional asphalt felts, resists wrinkling or buckling, so it lets your shingles lay flatter for a better-looking roof
  • Versatile: Can withstand UV degradation for 180 days when left exposed

Conventional organic felts can absorb moisture, causing severe buckling and wrinkling —and a terrible-looking

Deck-Armor™ Premium “Breathable” Roof Deck Protection resists moisture, so it lays flatter for a better-looking roof!

Deck-Armor™ premium roof deck protection combines high tear resistance and nail pull-through with a special slip-resistant surface for exceptional walkability — even on steeper pitches!

WARNING: “If your roof can’t breathe, the result can be decay, mold, mildew and costly structural damage!"

Today’s modern homes are built weathertight — so common moisture (from cooking, bathing, cleaning, etc.) has less chance to escape. Using non-breathable roof deck protection can create a barrier that traps harmful moisture inside your roofing system. Over time, that can cause roof rot, mold, mildew and costly structural decay.

That’s why GAF does not recommend the use of non-breathable roof deck protection under its shingles!


The Perfect Finishing Touch For Your New Roof Should Be A Distinctive Ridge Cap Shingle

seal-a-ridgeA Protective Ridge Cap Shingle Will:

  • Insure reliable protection at the highest-stress areas of your roof (the hips and ridges)
  • Provide a higher quality and more cost-effective alternative to using cut-up strip shingles as your ridge cap

Seal-A-Ridge® distinctive ridge cap shingles are a key part of the GAF Smart Choice® Roof System Solution, and have even earned the prestigious Good Housekeeping Seal.

Homeowner’s Best Choice

  • The Right Colors: Designed to complement the color of your roof’s shingles.
  • Stays In Place: Dura Grip® self-seal adhesive seals each piece tightly and reduces the risk of shingle blow-off.
  • Uniform Look: Machine-cut design delivers a uniform look; much better than using cut-up strip shingles.
  • StainGuard® Ltd. Warranty: Helps assure the beauty of your ridge cap shingles against unsightly blue-green algae (Tuscaloosa, AL plant only).*
  • Peace Of Mind: Covered by a ltd. wind warranty against manufacturing defects.shingle-camelot-logo-stainguard


Poor Attic Ventilation Can Ruin Your Insulation, Destroy Your Shingles, And Raise Your Energy Bills!


Why Take Risks?

It is estimated that 9 out of 10 homes in North America do not have proper attic ventilation. Why? Because most people are unaware that attic ventilation can impact the longevity of their entire home!

For example, in the summer, an improperly ventilated attic can cause heat to build in excess of 160°F. This superheated air eventually penetrates the ceiling insulation into the living area below.

Types of damage that can result include:

  • Premature aging of your roofing system (“fried” shingles)
  • Warping, cracking, or breaking down of wood framing
  • Damage to siding, exterior or interior paint, and wallpaper
  • Higher energy costs

A properly ventilated attic can help reduce the load on your air conditioner by moving the superheated air out of your attic before it builds up and causes damage.

In the winter, various household appliances, bathtubs, showers, and cooking vapors can contribute to excess moisture build-up. Improperly ventilated attics will allow this moisture to collect and cling to the underside of the roof. There, it will condense and fall, soaking the attic insulation and reducing its efficiency

Additional structural damage can include:

  • Roof deck warping and rotting of the wood frame
  • Mildew growth
  • Buckling of shingles and felt

Finally, attics should be properly ventilated to help prevent ice dams in cold northern climates. During the winter, ice and snow on a roof will melt and run down the deck to the cooler eaves. This run-off can re-freeze, creating an ice dam that will trap moisture on the roof. The moisture can eventually back up under the shingles and enter your home — causing hundreds or thousands of dollars of damage to your ceilings and walls. Adequate attic ventilation will reduce the amount of initial melting that occurs on your roof, thereby reducing the chance that ice dams will form.

Proper Attic Ventilation

V_AirFlowProper attic ventilation systems allow a continuous flow of outside air through the attic (see illustration at right), protecting the efficiency of the insulation and helping to lower temperatures in the living space.

It consists of a balance between air intake (at your eaves or soffits) and air exhaust (at or near your roof ridge).

The FHA (Federal Housing Administration) recommends a minimum of at least 1 square foot of attic ventilation (both intake and exhaust) for every 300 square feet of attic space. For example, if your attic is 900 square feet, you need a total of 3 square feet of ventilation. This amount is generally divided equally between intake and exhaust ventilation (i.e., 11/2 feet of each), to insure proper air flow through the attic.


Help Prevent Shingle Blow-Off And Eliminate Waste With An Eave/Rake Starter Strip

Pre-Cut Eave/Rake Starter Strips Are One Of The Most Overlooked Parts Of A Roofing System!

weatehrblocker-photoThat’s because it’s easy for a contractor to use a cut-up shingle as the “starter” course on your roof. Unfortunately, cut-up shingles may not have properly positioned adhesive to ensure adequate wind resistance.

Using a pre-cut eave/rake starter strip will:

  • Provide a cost-effective alternative to using cut-up shingles as your starter course
  • Include a high-quality, properly positioned adhesive that will tightly lock your shingles in place to help prevent blow-off
  • Be easy to use and install, with no cutting on the roof

WeatherBlocker™ Eave/Rake starter strip is a key part of the GAF Smart Choice® Roof System Solution.

Homeowner’s Best Choice

  • Versatile: Can be used with most English, metric, premium and oversized shingles.
  • Great Performance: Dura Grip® adhesive locks the first course of shingles in place, reducing the risk of shingle blow-off.
  • For Maximum Protection: Also install along rake edges to help protect shingles from wind uplift (and avoid the mess of hand-sealing the rake edges).

Professional’s Best Choice

  • Saves You Time & Labor: No more wasted time cutting thick laminated and strip shingles allowing you to offer greater homeowner value.
  • Eliminates Waste: No need to waste premium shingles for starter strips.
  • Safer: Perforated design eliminates cutting.
