No, this stuff is super bomber. I've seen it last without roofing material over it through some of the most brutal winters around. Don't waste your time or money with felt paper.

In my opinion it is not necessary but many project specifications require it. Check with your local building codes.
I did install a 30 lb felt paper over the ice and water shield just to rest easy at night

Can you use shingles over ice and water shield?
That means I will have to use nails which will penetrate ice and water shield.
Is this acceptable? what are the other options to finish up the roof?

Answer: 
a roll is about 75ft. long. assuming that the area that you mentioned is 16ft in height and 20ft. in length then you will need 6 lengths of 20 ft. at 36in. wide over lapping 3in. starting at the bottom (6 x 20 = 120 ft.) two rolls = 150 ft. you will have about 30 extra fee of material left over.

Answer: 
It covers approximately 200 square feet, so you will need about 4 rolls. Cut it into 8' to 10' pieces for installation and overlap your pieces by 6". Make sure to use the rip cord feature, it makes installation a lot easier.

Customer Reviews

Rated 4.4 out of 5 by 54 reviewers.
Rated 5.0 out of 5.0 by 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. October 18, 2016
Rated 5.0 out of 5.0 by 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 October 25, 2016
Rated 2.0 out of 5.0 by 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 September 23, 2016
Rated 3.0 out of 5.0 by 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. September 27, 2016
Rated 5.0 out of 5.0 by Great product This is easy to install and works beautifully to make my very flat roof water tight. Great product. August 16, 2016
Rated 4.0 out of 5.0 by Spendy but inspires confidence I used this underlayment on a low sloping roof in a windy rainy and sometimes icy climate. The sheeting was also a little rougher than I'd like. This material is almost like a thick rubber than bridged the small gaps and softened the edges. It helped a lot to have a partner to help roll it. It is VERY sticky and could turn into a mess quickly! August 11, 2016
Rated 5.0 out of 5.0 by Best on the Market! I have bee using this for as long as I can remember, it may cost a bit more that other brands, but your home is worth the extra! Shed style roofs, just do the whole thing, other roofs I use 6ft eve November 10, 2015
Rated 1.0 out of 5.0 by Waste of time and money The backing does not release, it tears in random strips. The adhesive on the backside edges will mess up the handling. The temperature should be below freezing when applied unless you want a giant mess. July 16, 2016
