Best Underlayment for Tile Roof in San Antonio

The Longevity of Your Tile Roof Depends on the Quality of Your Underlayment

A tile roof lift and relay is a critical service for restoring and maintaining tile roofs. Tile is a highly durable and long-lasting material, but it can be vulnerable to moisture intrusion if the underlayment begins to fail. That means replacing the underlayment for your tile roof is crucial for increasing its lifespan and keeping your roof in excellent condition.

At Dolan Roofing & Construction, we always advise homeowners to choose a high-quality underlayment for their tile roof. While alternative options can be cheaper, a higher-quality underlayment is likely to save money in the long run. Here’s what you need to know.

Is Underlayment Necessary for a Tile Roof?

Not only is underlayment necessary for a tile roof, but it actually may be even more important than the roof tiles themselves. While roofing tiles resist damage from storms, wind, and more, the underlayment is the source of water resistance for tile roofs. Without it, a tile roof would quickly fail and allow moisture to easily penetrate through to the interior of the home it protects.

Tile roofing is highly durable and can last for 50–100 years—or even longer. It’s long been a favored roofing material, particularly for warmer climates like we see here in San Antonio, due to its cooling properties as well. With such impressive durability, it’s easy to assume that the roofing material alone provides adequate protection for your roof. But the underlayment is not to be overlooked!

What Is the Best Underlayment for a Tile Roof?

Underlayments vary in terms of quality, cost, and water resistance. Here at Dolan, we recommend Westlake Royal (formerly Boral) TileSeal™ as the underlayment of choice for tile roofing projects.

All tile roof underlayments provide some protection against moisture, the primary point of failure for tile roofs. However, there’s a significant difference between water resistant and waterproof. TileSeal™ is a fully waterproof material that provides superior protection for your roof for much longer than other, cheaper underlayments. While alternative underlayments do have their place, especially when considering budgetary concerns, we always recommend TileSeal™ as the top product.

How Often Do You Replace Underlayment on a Tile Roof?

Typically, the underlayment on a tile roof should be replaced every 10–20 years or so. The exact frequency can vary depending on the climate in the area and a host of other factors.

The quality of your roof’s underlayment also matters here, as well. With a high-quality underlayment like TileSeal™, it’s more likely that your roof will go 20 years or longer without needing to replace the underlayment. More inexpensive underlayment materials, however, may need to be replaced after just 10 or 15 years. 

Don’t Skip Your Annual Roof Inspection

Because the lifespan of your underlayment can vary (just as the lifespan of a roof varies), it’s important to regularly monitor the condition of your roof. The first line of defense against underlayment failure is to schedule a roof inspection at least once per year. A roofer with expertise in tile roofing will be able to examine your roof and assess the health of the underlayment along with the health of your roof tiles. If necessary, they may recommend a tile roof relay, which may also entail replacing your underlayment. Keeping an eye on the health of your roof is a surefire way to avoid expensive roofing issues.
