UV exposure and resistance of underlayment

Anywhere the underlayment is exposed directly to sunlight, UV radiation will accelerate its deterioration. Even though an underlayment can serve as a temporary, short-term roof cover, it’s necessary to install shingles over this underlayment within 2 or 3 weeks. UV radiation can make the polypropylene fabric peel off first; however the bitumen part will still be watertight. Anyhow aesthetically it doesn’t look good. So installing the shingles as soon as possible is highly recommended.

UV exposure and resistance of underlayment shingle

Remember:

The underlayment is a key component of the roofing system. The price difference between underlayment options usually adds up to a few hundred euros in your overall roof replacement project. If you are investing in high quality IKO shingles that will improve your home’s value for years to come, choosing a better quality, more durable, water-resistant underlayment is well worth the extra cost. That is why IKO the professional range of Armourbase underlayments is highly recommended.
