GAF FeltBuster Synthetic Roof Underlayment (48" x 250')

GAF FeltBuster is a high-traction synthetic roofing underlayment designed to protect decks beneath shingles. The durable polypropylene construction resists tearing and moisture while its medium-gray surface stays cooler than traditional black felt for easier installation.


Key Features:

  • Enhanced Traction Surface: Special spunbond top layer improves walkability compared to typical asphalt felts
  • Durable Synthetic Build: Non-asphaltic polypropylene resists tearing, moisture absorption, brittleness, and oil leaching
  • Cooler Working Surface: Medium-gray finish can be up to 30°F cooler than black felt for more comfortable installs
  • Lightweight, Wide Roll: 48-inch width and 10-square coverage per roll speeds application over large areas
  • Better Aesthetics: Lies flatter to reduce wrinkle telegraphing for a cleaner-looking roof

A Sleek, High-Performance Base for Beautiful Rooflines

FeltBuster’s cool gray surface lays impeccably flat, creating a refined foundation that elevates any shingle pattern. I love the wide-format roll—it streamlines coverage and keeps seams clean for a polished silhouette. Pair it with dimensional shingles and crisp metal accents to highlight roof geometry. It’s a discreet essential that ensures a resilient, luxe finish from the very first layer.


Upgrade your roof’s first line of defense with GAF FeltBuster for durable, cooler, and easier installation performance.

I could be a foot model now!!!
Size: 1 pair black L
I wear work boots almost all of the time so I bought these to put on my feet with salycylic acid to moisturize and try to get rid of a stubborn corn on the ball of my foot. It helped drastically after a few nights of lounging in the house with them on.

Favorite treat
Flavor Name: Duck & Veggies, Size: 5 Ounce (Pack of 1)
My dog loves these treats the best, and the spoiled pooch has tried many! I love that these are super small sized, not messy, and low calorie which allows for lots of reinforcement while training. I also appreciate that the ingredients are very clean.

Buy these only if you love your dog
Flavor Name: Duck & Veggies, Size: 5 Ounce (Pack of 1)
I was looking for a dog treat that didn’t have sugar. And let me tell you these training treats are not only delicious to the dogs, but I love that the ingredients do not include any sweetener. I don’t think it’s a good idea to give our dogs tons of sugar, unless we’re brushing their teeth every day like we do for our own teeth. So for the longevity of my puppies teeth, she’s gonna get these high-quality yummy Yum‘s. I love that I can break them apart and make more treats out of the treats they gave so the bag last for months, even with daily training.

Perfection!
Flavor Name: Duck & Veggies, Size: 5 Ounce (Pack of 1)
Wonderful treat. My pups go wild and bounce around with pure joy. I have to hide the bag because these two figured out a whole MacGyver plot to snag them when I wasn’t looking. Cheeky little boys.
