BUILDING PRODUCTS FOR A BETTER FUTURE

There’s a reason why more roofers and homeowners are turning to synthetic roofing underlayment. Actually, there are lots of reasons—and one of the biggest is that synthetic underlayment makes for an easy installation job that is prone to fewer problems over the lifespan of the roofing system. That said, mistakes are still possible, and that’s why we’re going to show you how to avoid some of the most common ones. Read below to learn more.

1. Understanding Product Specifications

Getting the specs right is key when working with synthetic roofing underlayment. You’ll find important details like weight, tensile strength, and how breathable the material is on the packaging or in the technical sheets. If you don’t get these right, you might end up with a roof that doesn’t hold up or perform as expected. Make sure the underlayment you choose is a good fit for your roof, considering the local weather and the type of roof you have. Also, double-check that it meets the building codes in your area. Getting familiar with these specs means you can pick the perfect underlayment for a roof that lasts.

2. Proper Storage and Handling

Handling and storing your synthetic roofing underlayment correctly is just as important as choosing the right one. Keep it dry and off the ground in a cool, shaded area to prevent moisture damage and warping. When moving rolls, be gentle to avoid creases or tears that could compromise its effectiveness. Also, ensure it’s stored away from direct sunlight, as UV rays can weaken the material over time. Proper care before installation ensures the underlayment remains in top condition, ready to provide the best protection for your roof.

3. Correct Installation Techniques

Proper installation of synthetic roofing underlayment is crucial for long-lasting roof protection. Ensure the material is laid flat and smooth to prevent water accumulation underneath. Adhere to the manufacturer’s recommended overlap measurements to seal out moisture effectively. Use the appropriate fasteners to secure the underlayment, preventing wind uplift or displacement. While efficiency is important, careful installation guarantees that the roof is well-protected. A carefully installed underlayment forms a reliable barrier, safeguarding the rooftop against the elements.

4. Weather Considerations

When choosing and installing synthetic roofing underlayment, weather conditions play a pivotal role. Select a product that’s suited for your local climate. That can mean a UV-resistant product if you anticipate the roof will remain uncovered for a while, or a product—like for example, peel-and-stick underlayment—that can help you protect the rooftop against ice dams and moisture infiltration. Keep in mind, too, that installation on a dry, calm day helps prevent complications like moisture trapping or misalignment due to wind.

5. Choosing the Right Underlayment for Different Roof Types

Selecting the ideal synthetic roofing underlayment depends on your roof type. Steep-sloped roofs require underlayments with strong traction to prevent slips during installation. For low-slope roofs, look for products with high moisture resistance to combat potential water pooling. Metal roofs benefit from underlayments that reduce noise and are resistant to high temperatures. Understanding the specific needs of your roof type ensures the underlayment not only fits perfectly but also enhances the roof’s durability and functionality. Making the right choice here is key to long-term protection and performance of your roofing system.

6. Ensuring Adequate Ventilation

Adequate ventilation is crucial when installing synthetic roofing underlayment. It’s not just about protecting your roof from the elements—you also need to prevent moisture buildup that can lead to mold and structural damage, especially on low-sloped roofs where pooling can be a problem, or in areas where high humidity proves problematic. Where needed, choose an underlayment that allows your roof to breathe so that you can promote air circulation and reduce the risk of condensation.

7. Regular Inspection and Maintenance

Regular inspection and maintenance are key to maximizing the lifespan of your synthetic roofing underlayment. Even the best materials can succumb to wear and tear, so it’s important to check for signs of damage or exposure after severe weather events. Look for tears, punctures, or any areas where the underlayment may have come loose. Addressing these issues promptly can prevent water infiltration and more extensive damage to the roofing system.

8. Choose a Reliable Brand

When it comes to choosing a synthetic underlayment, your best bet is to go with a reliable, well-known brand that is backed by a solid warranty. With Epilay’s products, you get both—a quality product, plus a warranty that offers protection against defects. For example, our most lightweight product—Protectite PlasFelt—offers a 20-year limited warranty. And if you’re looking for synthetic underlayment that offers a lifetime warranty, check out our peel-and-stick products like EpiStik Plus.

No matter which Epilay synthetic underlayment you choose, you’ll be getting a quality product designed to work with a broad variety of roofing materials and in just about every climate. Choose the thickness you need for your next product, and be sure to follow the provided installation instructions. Between that and the tips provided above, you can make it easy to avoid all the most common problems when it comes to installing underlayment.
