Synthetic Underlayment for Tile Roofs

Is Synthetic Underlayment Recommended?

We have not been a fan of synthetic underlayment for several reasons. Did you know that nail holes in synthetic underlayment for tile roofs can pose a water infiltration risk? This is exactly why we feel you should be very cautious when considering synthetic underlayment; its inability to adhere to nails, potentially compromising your roof’s waterproofing.

Why Do We Not Recommend Synthetic Underlayment?

There is a Nail Hole Vulnerability.  Synthetic underlayment, unlike other types of underlayment, lacks the ability to effectively seal around nails. When nails are driven through the underlayment during tile installation, it creates holes that synthetic materials do not adhere to, leaving an open path for water to enter your roof system.

That leaves water intrusion concerns. Without a secure seal around nail holes, water can easily find its way into your roof structure, leading to potential leaks, moisture damage, and costly repairs. These vulnerabilities can jeopardize the integrity of your roof, compromising its ability to protect your home.

In regions like Phoenix, where wind-driven rain can occur during storms, the lack of adherence between synthetic underlayment and nails becomes even more problematic. Strong winds can force water through the gaps around the nails, exacerbating the potential for water infiltration.

What Type of Underlayment Does TraVek Recommend?

Proper underlayment is essential for a watertight tile roof. Opting for alternatives like modified bitumen underlayment ensures a secure and reliable seal around nails, minimizing the risk of water penetration and providing superior protection against leaks.

Modified bitumen underlayment has proven to be reliable, and offers excellent nail adhesion, meaning it effectively seals around nails to create a tight barrier against water infiltration. Its reliable adherence and compatibility with tile roofing systems provide enhanced waterproofing, reducing the risk of leaks and water-related damage.
