It's crucial to have ice and water shield installed on/around certain areas of your roof, like roof valleys, around penetrations, and on roofs with specific pitch. Because of its importance, every roof needs to have it.
At Bonac, we install ice and water shields to protect roofs from the elements, to provide that extra protection that valley metal can't.
