Differnce between Grace Ice and Water Shield and Corning Starter shingle roll, other than width?

Can the 36" wide roll of Grace I & W Shield be cut into 9" W pieces? What is the difference between this product and Corning Starter shingle roll, except width?
Asked by: Edina
Starter shingles on a roll are designed to cover any gaps between the butted edge of shingles, primarily for decorative reasons. Grace Ice & Water Shield is designed to provide protection from leaks caused by ice dams or wind driven rain. In many regions, use of a product like Grace Ice & Water Shield is required by building code, and starter shingles will not satisfy this requirement. We would recommend you use both product types.

How Bad is the smell?

There is a warning: Due to its slight asphaltic odor, do not apply where membrane is exposed to interior living spaces. I am building a playhouse approx 8 x 10 x 6 foot high with a 2.5/12 pitch roof. The roof decking is 1/2 inch exterior plywood. The rafter beams are exposed inside. I do not intend to "finish" other than painting the interior of the playhouse. Is this a bad choice for this application? Is this product okay to use in the San Francisco Bay Area, or do I need to use the ULTRA version?

Ice & Water Shield 36 in. x 75 ft. (225 sq. ft.) Roll Roofing Underlayment in Black is rated 4.5 out of 5 by 60.
Rated 2 out of 5 by from Ice and water shield Rip cord was a help but the paper edge would often tear off and I would have to lift up the side and try to grab the center rip cord edge to continue the lay down. At that point a wrinkle would occur. You have to be very patient or you will find yourself throwing large waded pieces off the roof. I found the Owens Corning product with the two separate plastic sheets far superior but the adhesive not as good as the Grace product

Rated 5 out of 5 by from Excellent Product This product REALLY seals and keeps the water out. It adheres to the sheathing - no nails required, and self-seals any nail holes created by shingling or any other activity. The only drawback is that it is a little awkward to install in large sheets, because the material is floppy and wants to stick immediately to anything as soon as the backing paper is removed. For this reason the directions suggest about 15 feet as the maximum length piece to work with. On the other hand, it can be shaped around almost anything, and cut into smaller pieces for patching around obstacles. Because it bonds to itself so well, you can even install it vertically and cut patch pieces to fix small "oops" locations. It is somewhat expensive, but in the context of an entire roofing job, maybe 10% of the whole cost. But why scrimp on materials when you want a roof that will be trouble-free for at least 20 years? All-in-all, a truly great product. I won't use anything else.

I also used it as flashing under and on top of the edges of two skylights by cutting 6 inches wide strips. It sticks to plywood, but once it touches metal flashing it is impossible to pull away. Laying it down requires two people on both sides to: peel away the paper with one hand (each person) and smoothing out the rubber shield on the surface ...... while holding it 4-6 inches above surface. I tried to do it alone and I wasted 7 feet, because once it folded, it was impossible to pull it apart. But that's why this stuff is so good. My wife was willing to help and together we applied it on entire roof. I wish they had this stuff 20 years ago.

Rated 3 out of 5 by from Sticky stuff It's a good product if you can lay it out flat and straight. I had a difficult time trying to lay it out without wrinkles and sticking to it self.

This is a good product and I would have rated it higher except for the fact that when I installed it the "RIP CORD" feature that is suppose to help slit the paper backing in half to make easier to install actually RIPPED a hole though the entire product while I was laying it down in the valley of my roof. The "RIP CORD" was embedded so deep into the rubber in some parts it just split right through the rubber instead of just the paper. This was very annoying since I was trying to protect the roof valleys and it splits a hole right in the valley, not to mention the premium price you are paying to install it. This was my first run so I learned from it and never used the "RIP CORD" feature again and didn't have any problems with the other valleys. I will use the product again and I do recommend it....... JUST DON'T USE THE RIP CORD......IT SUCKS!!! and it will "RIP" a hole in your expensive underlayment!

Rated 5 out of 5 by from Grace ice and water shield This was recommended by contractors and I can see why. It's everything as advertised and more. Easy to apply and no worries of a leak on a 2-12 pitched roof again

Rated 5 out of 5 by from Great product by VERY sticky I installed this product over the entire 24x10 ft roof over an existing deck. It took two days to install. The first day was about 70 degrees outside and everything it touched, even slightly, it stuck to, creating wrinkles in the underlayment. It actually laid down so poorly that after 3 rows out of 7 or 8 rows, I decided to stop and regroup. The next day, it was about 50 degrees outside and I went at it again. A totally different experience! The product was nowhere near as sticky and was much easier to lay down. It was easy to lift the product and relay it. In fact, I actually pulled up (with a lot of blood, sweat and tears) most of what I laid the previous day and relaid it. This time it laid down perfectly with no wrinkles. In the end, I was very happy with the product and was thankful for the 20 degree drop in temperature between the two days. This was my first time laying the product and I did it by myself. I think installing it with the help of another person would make it much easier but it can be done by one person. If you're installing it in the summer, it will be treacherous to deal with. In the late fall or early winter it will be a breeze.
