A TPO roof lasts between 15 and 30 years, with an average lifespan of around 22 years. Your roof’s lifespan depends largely on how you care for it. Regular roof maintenance and timely repairs can help extend your roof’s lifespan by preventing minor issues from becoming major problems that shorten its functional duration.
TPO has several qualities that make it a top roofing option. Apart from being one of the least expensive roofing options, it’s fairly resistant to tears, impact, punctures, fires, and wind uplift. The material is flexible enough to handle thermal expansion during hot weather and contraction during cold weather. TPO is also less likely to experience mold, mildew, and algae growth, as well as dust buildup.
TPO roofing is waterproof. It consists of hot-air welded seams that create a water-resistant membrane. If you live in an area that experiences heavy rainfall regularly, you can apply a fluid coating over your TPO roof to make it even more waterproof. Whatever you decide, be sure to have your pro weigh in; they’ll have the experience to tell you the best option.
