Ice And Water Shield Entire Roof

I just recently asked grace about this.

Ice and water shield entire roof. The situation was a slate roof on a 120 yr. The guy also talks about how the ice water shield seals itself around roofing nails which helps to distinguish it from a traditional underlayment product e g. Ice and water shield the whole roof. Ice and water shield is a great product that can be used in spots to protect the most vulnerable areas of your roof or as a whole roof underlayment to protect from ice dams water dams storms and leaking in any area of the country and any weather.

Ice and water protector sometimes also referred to as ice and water shield is a waterproof roof underlayment membrane developed to protect vulnerable areas on a roof from ice and water damage. In the video it s been installed on the entire roof. The video shows you exactly what ice water shield looks like and where it s installed. Underlayment typical 15 tarred felt underlayment provides back up protection against water intrusion only as long as the primary roofing material.

Do you need to put it on the entire roof or and also do you need felt as well in addition to the ice and water shield. And the question was to what extent do you need ice and water shield on the roof. From hud path best practices guide.

Ice and water protectors sometimes called ice and snow shields in cold climates are made with polymer modified bitumen. And they were talking about putting on i guess ice and water shield. Old brick firehouse currently used for dead storage by the town i think one small room is heated but not the whole building. The arguement that oh i would hate to be the next guy having to remove the ice and water shield couldn t you just remove the shingles leave the ice and water down and then put new ice and water on top of the old.
