A: Hello Rich, glad to help. I would personally go with a EPDM Rubber that can be glued down to the roof deck & will provide UV protection. Grace Tri-Flex is great stuff but will not work in the example you provided. If you didn't go with the EPDM Rubber (Sometimes refereed to as a Pond Liner) I would go with Grace Ice & Water Shield Roll Roofing Underlayment. The EPDM Rubber however is the only item that was designed to be a primary roof & not just the underlayment. I hope this Helped.
A: Hello Ham, glad to help. Yes it can be, as an underlayment, not a primary layer or surface. IF it is in that environment also overlap a full 2 feet when installing starting from the bottom & working upwards. This is a propitiatory synthetic blended sheet. Hope this Helped.
A: This is made of woven synthetic material (kind of like tarps are made). Continuous moisture exposure should not degrade the material itself. Sunlight would affect it the most by causing it to break down but since it will not be exposed it should be fine. It would not be a good material for holding water though, but as a barrier it will be fine.
A: Hello Juan, glad to help. You will need 3 roles. Each roll covers 1000 square feet. Hope this helped.
A: Hello Timbuck2, this stuff is amazing! Placing under a metal roof I would personally prefer it to be mounted to furring strips 1st vertical & then horizontal to give the roof a breather channel. What I layed down was 1 inch x 3 inch dimensional furring strips. Attached the roof panels directly to the horizontal braces. I also had my strips situated with a gap of exactly 2 feet between the horizontal furring strips & included foam board insulation. when done I had a roof with a 1 inch vertical channel to help with breathing. My underlayment has survived quite well. This is what I did & it worked out great for me. BTW, I was coached by a few Professional Roofers to build my roof like that. It works well, very well. Go Ahead. Hope this Helped.
A: Hello JW, glad to help you. No. Grace underlayment should not be used at slopes less than 2:12, provided the slope is also acceptable to the primary roof covering. On slopes of less than 3:12, Grace membrane should be half-lapped a full 24 inches over the underlying course, shingle style. Hope this helped.
A: Ice & Water Shield is a self-adhered underlayment, and is designed form a seal with the roof deck, and around fasteners, to provide waterproofing protection from ice dams and wind driven rain. TRI-FLEX is a mechanically attached water shedding material. It sheds water, and does not seal to the roof deck, or seal around fasteners. In many geographies, a self-adhered underlayment is required by building code at the roof eave, and in valleys. TRI-FLEX will not satisfy this code requirement. In areas where self-adhered underlayment is required, you may use Ice & Water Shield at the roof eave and in valleys, and TRI-FLEX on the rest of the “field” of the roof.
A: This material is fairly tough. I would think it may last for several years if you keep it fairly clean (no leaves piled up). I have been using some of this that I had left over from roofing my home to cover some materials for over a year and it looks in good shape except for some staining (mine is gray not black). It is located in the shade though, may not last as long in direct sunlight.
A: Hello Turbo888, I wouldn't expect it to past the 6-7 month mark at the outside. Being draped & tied to the wire especially if you live somewhere with wind, I wouldn't count on it lasting that long at all. It is great stuff for roofing underlayment & is strong and tear resistant, however this stuff isn't made to perform this way. Hope this Helped.
A: Yes. If put on properly, it is waterproof. (I've had it on a shed, exposed, for almost a year without a leak)
A: No, this is not waterproof.
A: TRI-FLEX is a premium synthetic water-shedding membrane. When installed using fasteners with 1” plastic caps it will prevent the ingress of rain. Follow fastening and overlap guidelines to ensure protection against wind driven rain. For slopes < 4:12, the product should be half-lapped.
