JosephHDATL, the PDF you linked to does not appear to be the product that this question was asked about. If you find the correct one, I would be interested in reading it myself.

Rated 3.0 out of 5 by 11 reviewers.
Rated 4.0 out of 5.0 by Easy and fast to work with - great for DIY Sheds and Lean To roofs. Cheapest way to make a roof to keep rain and the sun away. Easy and fast to work with - great for DIY Sheds and Lean To roofs. I have used both the white and copper color on 3 sheds and a 180 sq ft lean too roof (car port style), some small over the door way small lean to roofs. Remember install works best when it is HOT out. The hotter the better. Roll out and let it "relax" in the sun just like the directions say. TIP: if you are putting this on a temporary roof or shed you don't need to coat the roof felt entirely with Henry's adhesive cement - 50% or less works fine and saves time and materials. Once the tar and Henry's melt the roof is not going anywhere - you learn this when it is time to tear a temporary roof off and dissemble. Use LOTS of staples with the tacker aka hammer stapler to apply the roof felt. Sometimes I didn't use enough and as I repositioned the roof it pulled the roofing felt up - what a mess!! Be sure to start at the bottom and work up - same as you would with shingles. Remember, per the instructions - this is NOT FOR A FLAT ROOF. The minimum slope is 2 foot drop over 12 feet? I have gone below the minimum and still had no problems. TIP - I recommend the thinnest underlayment as the real think products are very difficult to roll out and get them to lay flat and can result in carpeting or bulges. TIP - cutting - use a 4' level and box cutter razor but cut / score from the back side. For small custom pieces use a pair of metal sheers. TIP - a heavy roller really helps spread the adhesive and flatten everything. TIP: position the striped line that shows the correct overlap. Have fun! October 9, 2014
Rated 1.0 out of 5.0 by poor quality The product is very thin and if you happen to bend it, and you will, it will crack and you'll end up with a damaged new roof. October 23, 2015
Rated 5.0 out of 5.0 by Low-Slope Roofing Specialist I use Mineral Guard for low slope roofs. Not flat roofs, low slope roofs. It's not designed for flat roofs. On a low-pitch roof though, Mineral Guard keeps water off. I've never had problems with it. July 31, 2015
Rated 1.0 out of 5.0 by no warranty Read the one paragraph warranty. This product carries no guarantee against leaks. Only a manufacture defect. Unlike a previous poster this product is designed to go under shingles. Read the paper work. It is designed to go in valleys, under dormer flashing. It is not capable of handling any ponding water. It is for low slopes. Most manufactures refer to it as a utility product with no wstranty . It is very brittle and difficult to get to lay flat on a hot day. There are better products. March 14, 2015
Rated 5.0 out of 5.0 by not an underlayment after reading a few reveiws, I realized people where using this produ t as an underlayment ( or in some cases a waterproofing membrane. with that said, this product is neither of those. this product IS and only is a roll of one giant shingle, meant for low slope roofs ( generally 1/12 to 3/12 slope). any less of a slope ( puddling water metioned in one review)use a flat roof system, any more regular 3 tab shingles are fine. when installing each coarse should overlap by at least 3" and when two pieces are butted together overlap by at least 6", use a roof cement to seal them. and seal all nails showing nails January 29, 2014
Rated 5.0 out of 5.0 by Great when used as an underlayerment for tile roofs I live in Albuquerque at an elevation of 5600 ft. Tile roofs are popular here but often fail to live up to their advertised life of 30 years. After about 15 years the underlying roofing paper dries out, shrinks and rips leading to leaks in the roof. Rolled roofing provides an added barrier of protection given its ability to withstand the elements on its own; its thicker with a mineral top layer. For a homeowner like myself its easy to work with, rolls out flat and is easily nailed down using cap nails. I've redone over 1200 sq ft of my roof thus far working by myself. How did I find out about using rolled roofing as an underlayerment for tile roofs - from local roofing contractors. As a side note, its not for use on flat surfaces; there must be a slope capable of shedding water. March 17, 2013
Rated 1.0 out of 5.0 by Not Quality This stuff is absolutely the worse. I had a small roof to repair this year, 12x24 so I purchased several rolls had to dig to the back of the pallet to get new ones that hadn't been returned. Should have been my first clue. I used tri-flex for the underly which saved the job. Story: this year I had to replace a roof so I had to cut out the rotted roofing and replace it and then put down all new sheathing sealed it and then put down the Grace Tri-flex (love it) for the underlay. After I put down the underlay I laid out this rolled roofing to let it stretch for a couple of days. In the middle of the summer we had a overnight downpour. The next day I went to check the underlay it worked great and all the rain did was beaded up like a car with a new wax job. However the rolled roofing was soaked really bad. Fortunately we had a lot of heat for several days to let it dry out. I couldn't return it so my next choice was to coat it. It took about four coats of Solar Flex and now it is waterproof. But if you use just this rolled roofing by itself you're in for a lot of leakage. The reason I can say it's waterproof is that we have had a lot of humidity this year and so far all it has done is roll off. I have checked after we have had the heavy humidity and like I said it is just rolling off, not pooling and not soaking through. Hope this helps. August 19, 2014
Rated 1.0 out of 5.0 by This product does not stand up to ponding water I have been in the roofing company for years, and this product WILL NOT withstand ponding water, is the worst system for hail damage. This is not a membrane roofing system. It is completely an asphalt shingle in a long roll. If you want a good roofing system, then you need to look elsewhere. Just remember, you get what you pay for, so if you pay for the cheapest roofing system, you will get the poorest roofing system as well. February 6, 2013
