Rated 5.0 out of 5.0 by JuanSC GAF Stormguard
I had been requested by an insurance agent to use the GAF Stormguard on a roof that had very little slope. The home owner had the roof replaced 2 time before & it always leaked causing damage. During a recent storm a tree limb broke & the wind brushed the limb against the rolled roofing causing tares but the water did not get through. I would highly reccomend this product for problem areas.

Rated 1.0 out of 5.0 by DoItAllJim Poor substitute for Grace Ice & Water Shield
After running out of Grace Ice & Water Shield in the middle of a big roofing project, we hustled back to our local Home Depot to see if they restocked. They are now only carrying this GAF product, so we bought that instead. We couldn’t be more disappointed!
For starters, when rolling out on the roof to cut a piece, we were surprised to find that there are no convenient markings (like the Grace product) for 6” and 1 foot. No biggie. The roll was way harder to manage on our (only) 4 pitch roof also, because the middle of the slippery roll would telescope out and down the roof. The plastic reinforced paper release on the grace product doesn’t do this.
The real problems started when trying to pull the flimsy plastic release film off while the sun was shining. You can’t pull the whole width off at the same time – it is really designed for half a width at a time. This means that if you are used to unrolling and pulling the release at the same time, this method won’t work well. Maddeningly, even half of the release sticks and tears while pulling off if the sun is shining on the finish side.. (It was 5PM sun, so I’m surprised at this. The Grace product behaved much better in the same (or hotter) sunlight.
The real frustration comes when it is all down. It’s slippery! You can sit on the Grace on a 4 pitch, but not even close with the GAF non-granulated product.
This product is inconvenient, frustrating, and unsafe.

The release liner on this product is terrible. If the plastic release liner is nicked, the liner shreds as you attempt to remove the liner from the adhesive. They could also greatly improve the liner by applying the silicone release to the opposite side as well. That way if the liner folds back on itself to the adhesive, the liner could still be removed. For such an expensive product it is a shame that they choose to use a cheap release liner.

Rated 1.0 out of 5.0 by Expensivedissapointment Horrible doesnt stick to new sheathing peels away and lifts up
I paid almost $100 for this and it does not even stick to new sheathing. Horrible stuff, I will stick to GRACO going forward. This was an expensive lesson. This stuff does not stick to what it is applied to. Save your money and order the GRACO or go to a roofing supply store to get the GRACO.

Rated 1.0 out of 5.0 by Farmerdave Save yourself trouble and buy Grace...
As another reviewer stated, this stuff is near junk compared to Grace. I got some in a pinch from The Depot, laid out one run, and then went someplace else and got another roll of Grace.. It doesn't stick well even after laying in the sun for a day. 20 minutes in the sun with Grace and its almost liquid..fills all the gaps.. I will never buy Gaf again.. Terrible

Rated 2.0 out of 5.0 by djrich first time buyer
was somewhat dissappointed. Box says 2 square and should read slightly less then 2 squares.Product is 36" wide and when put on a 12'x 18' deck roof following 3" over lap it was 9" short of covering roof. Noaw I have to buy more of this slightly expensive product to finish before shingling

Rated 2.0 out of 5.0 by HandymanDC Very disappointed... twice
Purchased this product since Home Depot no longer carries Grace Brand without ordering.... Helping a friend reroof a porch roof. Used this across the entire low pitch 2 on porch roof over both old and new wood. Product sticks very well to hands and especially latex (Nytril) gloves but that's about it. Had to staple down the edges on both new plywood and existing 1 x 8 sheathing. Cut and overlapped on itself and it pealed up in 15 minutes so I took a few minutes and pulled off the top gray plastic so the sticky rubber would adhere to itself, again it barely stuck even to itself!! Had to use a few staples to hold it down. Tried using it again 2 days later this time as a quick repair on a chimney top that had some large cracks just to get through the next few days of possible heavy thunderstorms. Figured this would be great. Stick it down to concrete and bricks and at least it would shed the water off the top... again wouldn't stick at all.... tried pressing hammering... kept lifting up. Folded corners together glue to glue still had to use PLIERS to squeeze them together after they came apart twice!!! Oh and air temperature 85 today and 90 for the porch roof. Home Depot needs to look again at the product and especially GAF needs to check in with these reviews and find out why their product doesn't work well at all. I've never used Grace but this product actually created more work for me going over it again and again then if I used simple rubber liner or tar paper. I do hope it seals around the nails better than it sticks to the roof...
