Can I Use Roofing Felt Under Endureed Synthetic Thatch Shingles?

SOPREMA

Pictured above are our Kilimanjaro synthetic thatch shingles from our Premium Collection on top of premium, self-adhering, waterproof underlayment. When installing standard asphalt shingles, many still choose roofing felt for a roofing underlayment. Sometimes, our clients ask us if roofing felt is suitable for use under Endureed’s premium synthetic thatch shingles.

The simple answer is: No. You can’t use roofing felt as an underlayment for our synthetic thatch shingles.

Roofing felt was the most common underlayment about 15 years ago. Then, synthetic underlayment products started taking over the roofing industry. Roofing felt consists of blends of cellulose, polyester, and bitumen or asphalt.

Should You Use Roofing Felt Under Premium Thatch Shingles?

It’s not appropriate at all to use roofing felt under our synthetic shingles. Yet, we can’t figure out why anyone would want to either.

Endureed synthetic thatch shingles are designed to last. Your premium synthetic thatch roof made from Endureed thatch shingles will most likely long outlive its warranty. Endureed thatch shingles are a high-quality, artificial thatch roofing product and you should not use outdated materials beneath our products. Think about this: It makes little sense to use a lesser-quality underlayment like roofing felt. The layers of synthetic thatch shingles you apply over it would far outlive the lifespan of roofing felt and consequently everything underneath it too!

So, don’t ever use roofing felt under our synthetic thatch shingles. Instead, use a high quality underlayment like a Soprema waterproofing membrane. See, you should use a premium, self-adhering, waterproof underlayment with a strong warranty. Choose an underlayment with a proven, long lifespan. Look, our products have a 20-year warranty. We want all products used alongside them to last at least as long too. It only makes sense. Right?
