Review on Zinc Protect - Roof Strip for Moss and Mildew Prevention, 2.5-Inch Width, 50-Foot Length Zinc Strip by Luis Norman

My shingles were replaced 8 years ago and black mold started to form on my north roof. After removing the form, I installed the strips along (just below) the ridge like I did on my old roof. It keeps mold at bay and lasts longer than the expected lifespan of premium shingles. But I highly recommend your roofer incorporate this when they install a new roof (which I forgot!). I can only assume that most of the zinc shafts sold there are rebranded, so it becomes a question of price, which is usually only a few dollars apart. The biggest difference was that I get free shipping with Prime and competitors (construction companies) kill you on shipping. As such, this review is for my intended use only and I have not used it for any other purpose.
