Tile Roof Services

We live in an area where there are tile roofs all around. The aesthetics blend so nicely into the surrounding environment. Although the tiles may last nearly forever unless a homeowner wants to change the look, the underlayment is subject to our extremely hot temperatures and over time begins to crack, and allow paths for leaks to form. In other words, a tile underlayment needs to be replaced every so often.

Replacing the tile underlayment in Arizona requires careful consideration of several factors.

Here are some things to keep in mind:

  1. Timing: Replacing the tile underlayment is a major project and should be done when the weather is dry and mild. Avoid scheduling the project during monsoon season because your roof will be exposed for a bit..
  2. Removal of Tiles: The tile underlayment cannot be replaced without removing the tiles first. This requires expertise and care to avoid damaging the tiles. Choose a roofing contractor with experience in tile roof replacement and underlayment replacement.
  3. Type of Underlayment: There are different types of underlayment available for tile roofs, such as asphalt-saturated felt, synthetic underlayment, and rubberized asphalt, G40, and modified bitumen. Consider the pros and cons of each material and choose the one that is best suited for Arizona’s climate and your specific needs. Just as a note, TraVek Roofing will NOT use synthetic material for an underlayment on any roof because we cannot stand beside its integrity.
  4. Local Building Codes: Make sure the replacement underlayment meets local building codes and regulations. This may include requirements for moisture barriers and flashing.
  5. Ventilation: Proper ventilation is essential for a tile roof to perform well in Arizona’s hot climate. Make sure the replacement underlayment includes proper ventilation to avoid moisture buildup and reduce energy costs.
  6. Contractor’s Experience: TraVek has more than 200 years of combined experience, and has completed thousands of tile underlayment replacements in Arizona. We are licensed, insured, and bonded.

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.
