Is this product water proof while laying exposed till you finish

Asked by: Trey
Yes. If put on properly, it is waterproof. (I've had it on a shed, exposed, for almost a year without a leak)

Will this product work on a roof with a less than 3/12 pitch?

Asked by: TM
Hello TM, good question. Grace underlayment should not be used at slopes less than 2:12, provided the slope is also acceptable to the primary roof covering. On slopes of less than 3:12, Grace membrane should be half-lapped a full 24 inches over the underlying course, shingle style. Hope this Helped.

Tri-Flex 48 in. x 250 ft. Synthetic Roll Roofing Underlayment is rated 4.7 out of 5 by 89.

I've had this exposed on a kennel roof for almost 18 months without a tear or failure (haven't had time to shingle yet). Won't shingle over this due to the time exposed, but this underlayment is the best I've ever used. Used it on a 14' x 35' shed and had to put the last 2 courses on in a stiff 15+ mph breeze (try doing that with felt!). Good traction while shingling. It does tighten up with exposure, but that helps take wrinkles out that could impact shingle placement. Great underlayment!

Rated 5 out of 5 by from Just expensive tar paper, returned to get ICE Shield instead. Just expensive tar paper, returned to get ICE Shield instead. Note : the weight of roofing products is not described on web page.

Rated 2 out of 5 by from PROBLEMS WITH PRODUCT. Product shrinks when sun hits it or hot. It lifts out of the valleys. I bought this because of the claim that is could stay uncovered up to six months. The listed problems occurred after a few days of alternating rainy and hot periods. 1st It didn't feel stable under foot as it was being laid. A problem when 20 feet up. It slides on the roof held only by stretching nail holes. I worry about leaks at nail holes because of stretching when you walk. 2nd When the product heated up it got real tight. -Enough so that is revealed seams in the rolls that pulled apart. 3rd This was the worst part. When it tightened up from the sun. It lifted out of the valleys. This required the product being cut and new felt being placed before shingling. Overall. I will not use this product again.

Rated 5 out of 5 by from Great Under lament Works really well easy to install, excellent durability, much better than felt. A little slippery when wet, only complaint I wish it had more lines for shingle alignment.

Rated 5 out of 5 by from Best investment I could have made After tearing off my old roofing and seeing how the felt paper was just crumbly apart I was so glad I bought the Grace Triflex underlayment . It is strong & lightweight & I won't be worried about it deteriating

Rated 5 out of 5 by from easy to use, light weight This material is thin and light weight. Very easy to use. It doesn't stretch or crease easily. It's as easy to cut as paper. It seems to be as waterproof as advertised and it won't absorb water and wrinkle and buckle like tar paper. It's easy for a one man operation to cut a piece to the entire length of the roof, tack one end down and stretch it out across the whole roof without a massively heavy roll sliding down the roof. Lots of material on a roll.

Rated 5 out of 5 by from Great product! Easier to install than felt. Tougher and more durable than felt. Lasts longer than felt - up to months before cover. Cheaper than felt. So why does anyone use felt? Well pleased.

Rated 4 out of 5 by from Excellent as temporary roof covering. Excellent as temporary roof covering. Has held up very well for more than 18 months while preparing to re-shingle.
