Grace Ice and Water Shield HT Self Adhering Underlayment

I don't know why, but one roll arrived as announced, but the rest two days later. In fairness to the company, the final shipment arrived by the time promised. Only had one tracking number. The product was all in good shape.

Some Insurers discount Homeowner policies for using wind resistant self-adhesive underlayment instead of felt, this is self sealing with screws (or nails) in case a homeowner wants to add metal roof in the future over asphalt shingles or tripods for weather stations dishes or antennas This is the high Temperature version especially for Hotter Southern States ( @ wildfire areas or Global Warming Areas) so the stuff does not melt under metal roofs

We had to remove shingles on our roof to make way for a room addition but because we were doing the work ourselves we needed something good to protect our house while we added the new roof. This worked great. It was a bit hard to handle in our tight work area and with grit from the old roof a constant cleaning problem but it sealed the old roof from rain and that was the important thing.
