Can it be left uncovered?

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.
Asked by: Patsfan
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: 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.

Is this rubber? Is it toxic? Can be used to line a vegetable garden?

Asked by: hrad
This product is not designed for this type of application. I would suggest checking the garden section of Home Depot for a suitable product.

18 in. x 50 ft. Asphalt Roll Roofing Detail Membrane is rated 4.2 out of 5 by 26.
Rated 4 out of 5 by from I used this membrane to cover 33' of gable ridge... I used this membrane to cover 33' of gable ridge line on a timber frame barn I'm building. I discovered I could not apply it as one piece; too sticky and unwieldy to apply this way. I applied it in 3 foot lengths, overlapping as I went. Seemed to work well. Extremely adhesive to oak boards!

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from This product has great sealing ability. I purchased this product to seal the area where the lower level of my roof meets the wall of the 2nd floor of my house. The adhesion of this roof membrane is amazing but be warned that you only have one chance to put it down smoothly on the roof!! I recommend that you have a helper. Take your time when lining up the membrane and work with small, more manageable pieces. I also used this product around the flashing on my roof windows. I don't know of any similar product that is on the market today.

Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from What Took Me So Long To Find This Product I have a torched down roof and was getting leaks from cracks created by sun damage, so I found this stuff any wow do I love this product! I have never experienced something that sticks this well, so the downside is don't let it adhere to itself and be careful if you are going to try to install it on a windy day. I've used 100 feet of this product. The trick is to lay out your set amount and only pull enough backing paper to stick down one end and fold the backing paper underneath then slowly pull the backing paper from underneath, while making sure you don't get air trapped. After installing you have to coat it within a month with roof coating, so I used Solarflex white roof coating.

Rated 1 out of 5 by from The paper on the bottom kept tearing. You get done rolling it out and it looks nice neat. then yo... The paper on the bottom kept tearing. You get done rolling it out and it looks nice neat. then you realize that a tear started 5' in into putting it down and it ripped right down the middle the hole length. So ok I bought two rolls maybe I got a bad roll nope both rolls were like that. END results is that it looks like garbage.
