ArmorLay 25 Synthetic Roofing Underlayment 04' x 250'

Cool Gray color. Great product. Very durable. Made it through winter snow and spring rain on a low slope roof, double layers with heavy overlap without anything covering it. This year I went new layers over the old and painted elastometic over the top. Will do metal roof over that. Holds up to intense UV exposure for more than 90 days.Fastened with plastic head roof nails.Will not rip in high winds.Lays flat.Great for new construction or temporary waterproofing.Great valueBest roofing underlayment coverage for the cost.

This was so easy to use, I’m a 60 yr old woman redoing the roof myself and I was very glad I purchased this. It had very good grip, lightweight and never tore. I felt safer walking in it than the asphalt shingles already down. I would highly recommend using this to anyone needing waterproofing and gripping for any project.

Very good product i like and if i had received an undamaged roll i would have given a 5 rating. I tested a small piece forming a cup and after filling with water it is waterproof, I also noticed how well it stays down and unlike roofing felt or tar paper it stays put and will not tare.

Great product. Works great for my metal roof. Not slippery at all and very strong. Much cheaper than other brand.

Light weight to work with. Covers more area per roll compared to roofing felt paper. Simplex nails hold it down well even in high winds. I recommend highly.
