Questions & Answers

Can I wrap it on my floor joists before installing a trex floor on my deck

Asked by: Kdog
I'm a roofing contractor and use this sort of membrane regularly. I intend to use this in conjunction with a Trex Rainescape system on my deck. Rainescape is a waterproofing system designed to shield the underside of your deck from precipitation. Rainescape suggests using their butyl tape and caulk at all joists and laps as the means to waterproof against fastener penetration leaks. Their tape is is extremely thin and anytime someone suggests caulk as a means of waterproofing beware. So this membrane, which is ice and water shield, has much more body (is thicker) than the Rainescape butyl tape. As such it will seal around the penetrating fasteners much better than the thin butyl tape and smearings of caulk. If you want to really go the additional extra mile get the HT version of this membrane (high temperature) designed to withstand heat generated by metal roofs. I don't think its necessary to go to this HT version but it certainly would be more forgiving against heat (if your deck is a darker color). As for concern that foot traffic might adversely affect it I doubt it. I expect it to compress somewhat from the weight but that's where the extra thickness provides extra forgiveness. The Rainescape system is better served utilizing a thicker more self sealing membrane such as this rather than their micro thin butyl tape. You'll have to cut the 36 inch wide roll down to workable 4-6 inch strips to cover the joists and trough seams etc... but considering the trouble involved in correcting a leaking Rainescape system probably well worth the effort.

Can it be used on CAMPER ROOFS????

Asked by: Sherry
It can be used on campers. Best to apply in the morning where as it gets Very sticky once the temp starts to rise. Make sure surface is clean of any debris,cut to size,peel and stick. Do not know how long it will last with different weather changes but is an excellent product and does what it was made to do.

Can I use ice and water shield roll roofing under a metal roof

Asked by: Daryl
Sometimes, but it depends. Grace's website states it "may be used on sloped roofs, under mechanically attached roof coverings such as asphalt shingles, slate, tile, cedar, and standing seam metal in many climate and assembly conditions (see limitations for additional information)." The limitations state "Do not install under copper, COR-TEN® , or zinc metal roofing in high altitudes" because of high temperatures. GRACE ULTRA™ is recommended in those applications. While many metal roofs cannot be installed over granular underlayment, since Ice and Water Shield is smooth (embossed) it may be compatible with your assembly. There are chemical concerns depending on your metal finish, so you should confirm with the metal roofing supplier. Many metal roofs are attached using screws, where Ice and Water Shield prefers smooth fasteners for the best seal. Note that grace makes GRACE ICE & WATER SHIELD® HT specifically for use under metal roofing. You would be well served to contact Grace's technical support and ask about your specific application to confirm the best product match.

Can i use this for a vapor barrier on a concrete floor before laying flooring

Asked by: Ritche
I would say yes. Might be a little over kill. It's an amazing product. I build tiny houses on wheels. I cover the entire roof with it. You will be doing the same thing.
