Compatible with multiple substrates and backed by a 10-year limited warranty, this underlayment is a reliable choice for professional-grade roof protection. ## Description The MFM Wind and Water Seal is a self-adhering roof underlayment with a non-slip polymer film. It has a high-temperature, rubberized asphalt adhesive that will not crack or dry while remaining protected by a split release film that is removed once the underlayment is installed. Make sure to install Wind and Water Seal underlayment with proper ventilation, because it is considered to be a vapor barrier. Wind and Water Seal is compatible with most sealants and primers and can be applied to plywood, OSB, foam insulation, house-wrap, rigid vinyl, and masonry, as long as the surface is clean and dry before application. This particular underlayment is ideal for protection against ice dams or weather conditions such as wind-driven rain because of its reliable, uniform thickness. It is recommended to apply this underlayment in temperatures over 50° F on decks that have a minimum slope of 3:12. This protective barrier is most effective when stored out of direct sunlight. Once applied, Wind and Water Seal must be covered within 60 days of the installation. MFM backs the Wind and Water Seal with a 10-year limited warranty. High elongation, flexible, and accommodates to the contraction and expansion of the application surface The minimum slope is 2in. per foot for installation. Self seals around fasteners. Overlapping guidelines for easy installation. Test Method Codes: ASTM D 5147, ASTM D 1970, ASTM E 96, ASTM D 903/1970.

I am a diy-er, and we are building our own house. I have always used asphalt underlayment and have recently become a convert to synthetic underlayments. This Wind & Water underlayment is the best of both worlds - it is heavy and obviously impregnated with some sort of asphalt, yet it also has the synthetic covering attached. I read somewhere that this underlayment sticks 'aggressively' to the roof decking. This is absolutely true. After applying this, my grandson and I decided that even a tornado would not take this stuff off the plywood we put it on; the tornado might rip the plywood apart piece by piece, but By God, there'd be this W&W underlayment on every single piece. UNFORTUNATELY, the underlayment ALSO sticks 'aggressively' to: Itself, the back of the peel-away paper, gloves and any other object it comes in contact with. Think heavy, large pieces of flypaper. We have 60 mph winds fairly often, so I am not complaining - we need this to stick on the roof without the metal for about a month until we can get the roof on (delays!!), but during application, we also lost a bit of material to mishaps in handling that resulted in this stuff stuck permanently into some unusable configurartion. Application: Today was about 85 or 90 degrees with a breeze of about 15-20 mph. The roofing underlayment became very pliant, which may have contributed to its 'aggressive' sticking, and the rolls are heavy. The rolls can be cut with heavy-duty kitchen shears. We tried several ways to apply this. Tips that worked for us on a 2:12 roof: Do not apply in winds of 15-20+ mph. The wind will catch and twist the peel-away paper and flip it onto the sticky surface. Trying to unstick the paper will sometimes result in disfiguring the underlayment; this is more probable the warmer the underlayment is. If you must apply with the wind, start on the side of the roof from which the wind is coming, adhere the end and then start pulling the paper off, thus rolling the underlayment along. Once you have a few feet down, step over the roll so that you are now following the underlayment down the roof. The action of your peeling the paper off the sticky side of the roll, along with the wind, will roll the underlayment along. Before you reach the end of the roof, stop and cut to size, then lay the underlayment down and ease the last of the paper out from under it. This stuff doesn't stretch well, but if you really mess up an area, overlaps are not too noticeable. The rolls are heavy and awkward but manageable for a 49 year old female in reasonable shape. We found that stepping all over the underlayment worked better than trying to roll it down. (Party on the roof at Nana's!) Overall, despite its price, the product was reasonable to put up and it sure seems to be on there. I will update this review should the underlayment decide to fall off. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/17924349-mfm-wind-and-water-seal-underlayment-single-roll](https://www.desertcart.id/products/17924349-mfm-wind-and-water-seal-underlayment-single-roll) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-10*
