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.

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.

Dormers with a roof slope of less than 9,5 degrees on a shingles roof
If you want to get more space and light into your house, then you can build up a dormer on your roof or add a winter garden to the outer wall of your house. Dormers avoid the potential valleys that will be created. Usually these solutions have very low sloped roofs. Sometimes these slopes are even less than 9,5 degrees, making them not suitable for standard roofing materials. Roof parts such as valleys, very flat curved parts or low slope inclinations might all be dangerous spots for driven rain and water, snow accumulation and ponding water.
To have all of these details 100% secure, IKO launched a unique solution: the installation of the “Thermo-adhesive system” in combination with IKO bitumen shingles (nailing not required).
In this blog post you will find out how to install IKO Shingles on dormers with a low roof slope.
