Answer: 
Grace Roof Detail Membrane adheres aggressively to common building materials such as plywood, OSB, vinyl, and metal surfaces. It is UV protected for temporary exposure. It should be covered with the roofing material, or metal flashing within 30 days.

I have a corner leak where addition met rubber roof and there is a deck on the rubber roof. Can I use this in the corners and up the wall 2 feet and not put roofing over it? It will have siding and deck, so sun exposure is not an issue.

Answer: 
Personal opinion: I would not use it in that way. Even though there is no sun exposure it is meant to be covered and I would recommend doing so.
On the wall cover with 30# roofing felt or Tyvek, etc.
On the roof portion I would cover it with the same material as your current roof (rubber roofing).
You already have a leak. This indicates you already have a problem with one of these systems: Read More

On the roof portion I would cover it with the same material as your current roof (rubber roofing).
You already have a leak. This indicates you already have a problem with one of these systems: siding, roofing or flashing. This material is to be used as a soft flashing, not a roof and not even a covering for sheathing (such as felt paper). It is meant as a last resort protection when all else fails and, water should have a way to drain off of the membrane without being left to stand for long periods, especially over its seams.
Your suggested use might work as a temporary fix, but I doubt it will be a permanent solution.
If, for example, you use this at the joint between wall and roof; the portion extending over the roof may be subject to standing water where the edges lap over your rubber roof. I would expect this weak area to eventually cause the Grace Membrane to lift up and peel back. This would again expose the leaking area to water, if that's where the leak is. If there is no leak there, then you haven't gained anything by covering it with the new membrane.
I used the similar product (Ice & Water Shield, "IWS") in the same way you suggest on a front hall "flat" roof with parapet walls on 3 sides and a house wall on the fourth. The IWS was applied directly to the roof sheathing & house wall. I took the IWS 18" up the house wall and covered the roof sheathing with it. Rolled roofing was then applied over the roof & up the walls the same distance as the IWS. It was then covered with aluminum flashing (back flashing). In this way all the otherwise exposed edges of the IWS were either covered and protected with metal flashing or roof coating.
All the large manufacturers of materials like these have excellent printed material (online pdf) and technical support staff. It wouldn't hurt to take advantage of those resources if you have any doubts about how to proceed. Read Less

Answer: 
The product is designed for temporary exposure, and needs to be protected from sunlight within 30 days. Additionally, the material is not designed to be applied directly to rubber roof materials such as EPDM, TPO, Neoprene, or PVC.

Rated 4.5 out of 5 by 22 reviewers.
Rated 5.0 out of 5.0 by Exactly what I needed I made a little free library and needed something to seal under a cedar roof. This was it. It stuck to the wood sub roof and I was able to staple the miniature cedar pieces to it and through a severe storm everything stayed dry. Perfect. July 19, 2016
Rated 5.0 out of 5.0 by A+ for roof penetrations The best product for base flashing chimneys. Under the step flashing and shingles. Turn up masonry @ 3-4". No more leaks July 19, 2016
Rated 5.0 out of 5.0 by Very good product. I've had very good experience with this. I recommend it. May 7, 2016
Rated 5.0 out of 5.0 by Best option for the money IMO I don't usually write reviews. I have been using this stuff for years and will not use anything else. There might be something better out there, but I know this membrane works. I read a few reviews on here and some people are having trouble getting it to stick. If it is cold, you need to heat it up. If the membrane is cold, you will not be able to press it into the wood grain on your roof, old or new. Which brings me to the next problem, it does need to be pressed into the surface you are protecting. Use a vinyl tile roller if you can, or at least slide a scrap piece or 2x4 over it with some body weight on it. The rubber backing has to be pressed into the wood. If it is 90 degrees out side and you are in the sun the work will be much easier, it will stick to whatever it touches and heaven help you if you need to remove it. As far a cutting goes, most versions of the Grace products have a very fine wire running in either 4 or 6 inch increments. They call it "rip cord" or something like that. Just grab where the wire is (you may have to fish it out or grab it with channel locks) and pull at a tight angle to the direction of the seam, it splits right apart. Don't be discouraged by the poor reviews, if you are not sure how to install this, or just about anything for that matter, look it up on you tube and watch the video by the guy who looks like he probably does it for a living. This also works great around doors and windows. Use a heat gun or hair dryer if it is cold out. Good luck to you, that is all. March 31, 2016
Rated 3.0 out of 5.0 by membrane Didn't work quite the way I thought it would, everything is great about it but the adhesive isn't that spiffy February 11, 2016
Rated 4.0 out of 5.0 by Lightwell roof repair. Needed to install a drain in small lightwell area and used GraceRoof Underlayment membrane. Easy to work with in layers. I did two layers then used aluminum roof coating to finish the job. Only reason I didn't rate it 5 is I want to see how it handles rain after a year. October 8, 2013
Rated 5.0 out of 5.0 by Grace Roof Detail membrance This water-ice barrier has excellent properties. It seals well and probably seals around screws and nails driven into it to some degree. It just takes a little practice to apply the barrier since it is very sticky and you will usually get only one chance to put it on a surface. If it sticks to itself, it is best to start over. However, the challenges to applying the material are a testament to how well it will serve as a barrier. I have not had experience with other brands, but I think this one is worth the higher price.
