TOUGHER: Unlike #15 felt that tears and rips easily under foot or high wind, SHINGLE DOG 15 will withstand much tougher installation conditions. SHINGLE DOG 15 is 25X stronger than 15# felt. Now that's junkyard dog tough!

LIGHTER: One roll of SHINGLE DOG 15 covers 10 sq. and weighs only 20 lbs., that's 6X lighter than #15 felt. One roll of SHINGLE DOG 15 covers 1000 square feet. Use fewer rolls, use less truck space, lift and carry a lot less weight on every job.

SMARTER: Upgrade from #15 felt, and forget about tearing, ripping, wrinkling, blow offs, hot oily surfaces, water absorption, and long term dry-out & cracking that plagues #15 felt. Wider rolls, fewer rolls, more coverage per lap, faster installation vs. #15 felt. Get a cooler grey surface, and synthetic construction impervious to mold growth. Now that's smart!
