Apply High-Temperature Synthetic Underlayment

What happens here

After the roof decking is in place, apply a high-temperature synthetic roofing underlayment over the entire surface. This material, often referred to as 'ice and water shield,' is self-adhering and crucial for providing a waterproof barrier, especially important for the unique radius roof where there are no traditional purlins to screw into. The high-temperature variant is used because it adheres better as temperatures rise, and protects the wood from overheating, warping, or cracking. Ensure proper overlapping of the edges to prevent water intrusion.
