What More is There to Know About Underlayment?
People ask how often they should replace the underlayment. The lifespan of tile roof underlayment in Arizona can vary depending on several factors, including the type of underlayment, the quality of installation, and environmental factors such as weather and sun exposure.
Typically, traditional felt underlayment has a lifespan of about 15-20 years in Arizona. There is G40 and Modified Bitumen, modified bitumen being the highest quality but G40 being very good. There is also synthetics, but jump to the last paragraph and read our warning about synthetic underlayments.
It’s important to note that in Arizona, the harsh sun and extreme temperatures can cause underlayment to degrade more quickly than in other areas. Therefore, regular inspections of the roof are recommended to identify any issues and ensure that the underlayment is functioning properly.
Overall, the lifespan of tile roof underlayment in Arizona can vary, but it’s important to choose a high-quality underlayment and have it installed by an experienced and reputable roofing contractor to ensure that it lasts as long as possible. Regular maintenance and inspections can also help to extend the lifespan of the underlayment and prevent costly repairs.

A VERY IMPORTANT MESSAGE: We say “Buyer Beware” when others tout that the newer synthetic underlayments can have a longer lifespan, up to 50 years or more, and that they are more durable and resistant to tearing, wrinkling, and water damage compared to traditional felt underlayment. In our opinion and experience, synthetic underlayments are not good. Just a real quick comparison to how it works is, imagine you are pounding a nail through a synthetic tarp bought from one of the big box stores. You have just created a way for water to enter through that tarp. When you use a material like G40 or Modified Bitumen, that material will snuggle up to the nail and create a seal that water will not go through. We very often see the leaks from synthetic underlayment that others have installed, and we will not install it because we know it will leak.
