Product Overview

Grace Ice & Water Shield HT fully-adhered, smooth surface roofing underlayment is specifically designed for high temperature applications such as metal roof assemblies. It delivers all the advantages of Grace Ice & Water Shield roofing underlayment with thermal stability metal roofs require. Not all high temperature roofing underlayments are the same. Grace Ice & Water Shield HT is an excellent high temperature ice and water barrier that follows in the footsteps of the original Ice & Water Shield, but is specially formulated to meet the higher service temperatures that are inherent to metal roofing systems. Grace Ice & Water Shield HT is formulated with a proprietary adhesive with temperature resistance of up to 260°F. The membrane forms a watertight bond to the roof deck, and seals around fasteners to around the nail of the primary roof covering and thus maintains its waterproof integrity on the roof deck. It also creates a strong bond to the roof deck. Grace Ice & Water Shield HT delivers optimal balance of adhesion and thermal stability for superior performance under the most demanding conditions.

  • Temperature resistance up to 260° F: Provides premium waterproofing for metal roofs
  • 120 day exposure: Delivers consistent performance over long, unpredictable construction cycles
  • Strong adhesion to the roof deck: Helps ensure a watertight seal, protecting roofs from harsh weather conditions
  • High quality seal around roofing nails: Delivers strong roof leak protection; providing peace of mind against costly call backs
  • Forms superior laps: Provides watertight installation with no special treatment of the laps
  • Dual barrier protection - rubberized asphalt is combined with polymeric film to form two waterproofing barriers providing maximum protection
  • Delivers optimum balance of adhesion and thermal stability for superior performance under the most demanding conditions
  • Protects under all standard sloped roof coverings - Grace Ice & Water Shield HT protects under slate, tile, cedar shakes, metal and conventional asphalt shingles
  • Protects roofs from wind driven rain and ice dams

Customer Questions & Answers

Coatings AFTER it cures?!

The instructions say to coat it after 30-120 days. But with what? Reflective coating that you use on rubber or tin roofs? Thanks~
Asked by: UglyBoY
It's on a fairly mild pitched roof already covered with EPDM. There is NO way to cover it with shingles, etc.

how is it install

Asked by: joe1111
I would not attempt to do any bigger piece than 3' long without an extra pair of hands because once it touches ANYTHING, it sticks! The same goes for ANY breeze....VERY sticky.

Ice & Water Shield HT 36 in. x 75 ft. (225 sq. ft.) Roll Roofing Underlayment in Black is rated 4.5 out of 5 by 36.

It is reasonably easy to install, although I didn't have the requisite experience and made a few beginner's errors. The unknown is how it will perform over the next 30 years...I have every confidence that it will perform well. This was the recommended type of underlayment for a metal roof because of its high temperature rating.

Rated 5 out of 5 by from A dry suit for your roof that will last forever imo We put the Grace HT on our old cabin in the U.P of Michigan. After removing the old original roll roofing. We applied the Grace HT to the entire roof, which has many dormers and valleys. Went on as expected as we had done our research prior. The roof deck is very old rough pine various width boards. Those old boards will never see the light of day again. The metal roofing was installed and I am confident that if a leak should occur in the metal, the Grace will not let it penetrate. And the inside of the cabin should stay much cooler in summers. Darn good stuff imo........

Rated 5 out of 5 by from Great water barrier with strong adhesion I bought enough of this for a double layer but soon realized that one would have been more than enough. There is no way water will penetrate this. Someone commented that this does not stick well, but I found it to stick to nearly everything. The only thing it doesn't seem to stick well to is damp wood. Particularly treated wood that is new and still damp. Dry/clean sheathing will have no problem grabbing onto this. The instructions say to nail it down for sloped roofs, but check this out. I had to repair a 8 foot vertical wall along the side of the chimney that had severe water damage. After the repair, I covered the section with this and it stuck like crazy... to everything. I didn't even nail it to the 8' vertical wall and it stuck. The only nails came from the vinyl siding that I later covered the wall with a week later. The only down side I can come up with it that it is expensive. If I had known how good this was, I would have only bought enough for one layer and saved some money. You get what you pay for and this is well worth it.

Rated 5 out of 5 by from Great product Although this stuff is an little tricky to put down, I can't imagine a roof leaking after applying. I used it to seal my camper tip out prior to putting my rubber roof back down after repair water damage.

Rated 5 out of 5 by from Excellent quality. This product really does the job. It is very tough and durable, sticks like crazy, and best of all, appears to be 100% waterproof. My amateur roofers seemed to have no problem applying it either. I expect this to last for many years. Well worth the money.
