      Q:Our roof deck is old hemlock 1X12 boards, with up to 1/4 inch gaps between boards. Should we fill those gaps?

        Q:How long is the product capable of withstanding exposure to sun and elements without a completed roof system ?
        by|Oct 26, 2022
        1 Answer
        Answer This Question

        A:  This product is UV resistant up to 180 days. However, please note, that doesn't mean the product should be used as a temporary "waterproof" roof. Since this product is not self-sealing, such as peel and stick underlayments, this product is intended to shed water under the primary roof covering - not be waterproof. For further information, please call our technical team at 877-GAF-ROOF. Thank you

          Excellent traction and walkability. No tearing under normal installation traffic. Has a tiny bit of stretch because it is a cloth.

          Other Possible Uses
          I realize this is a roofing product, but I'm thinking that due to its breathable nature, and the synthetic strength of the product, it could be used over insulation, say under a mobile home, or in my case the basement of my barn over the floor joists (insulation) where a vapor barrier would not work. What are your thoughts?

            Disappointed
            I bought this thinking it would be the cats meow. Very similar to VaproSheild. Not as waterproof as it looks or claims to be. Super easy to install, but doesn’t hold up well to a mid to heavy rain. If you’re looking to temporarily be water and weather tight before roof cladding, this doesn’t do the task. It’s almost like it absorbs water before it repels it.

            Response from GAFProductExpertDec 11, 2020
            Hello, thanks for the feedback. However, this product is not intended for use as waterproofing or watertight before the primary roof covering, such as shingles, are installed. This is clearly explained in the installation instructions on each roll. It is intended as a water-shedding underlayment for use under the primary roof covering. For a dry-in solution, you should probably consider a peel and stick waterproof underlayment or potentially tarping the roof before you're ready to install the final roof covering. Thank you for your feedback. gaf

            Installation excellent.
            Cannot comment on long-term performance as just finished installing. But this product is easy to cut, VERY tough for abrasion-resistance and tearing. Decent slip resistance. Would definitely use it again.

            Highly Recommended
            After deciding to replace the shingles on a leaky section of roof I picked up some deck armor and other products from home depot. Not having done any roofing for decades it took a little longer than I thought it would. At one point, with half the roof shingled, I ran out of daylight. Nothing to do but duct tape the deck armor (where nailed, and on appropriate edges) and hope it didn't rain. At 5:00am I wake up to sound of pouring the rain. It rained for about 8 hours with just the deck armor on the upper half of the roof. No leaks! The product doesn't claim to be waterproof but it saved my bacon big time. Also, walking on it in the middle of day to make sure everything was secure was easy as it wasn't slippery at all. I do recommend having someone to help put on this product if you live in an area that is windy. The wind can catch the material and blow it out of position quite easily.
