Answer: One layer of No. 30 (or Type II) felt underlayment
Explanation: For an asphalt shingle roof in a moderate climate with an average slope, one layer of No. 30 (Type II) felt underlayment is typically recommended. It offers a good balance of durability, water resistance, and breathability while providing reliable protection beneath the shingles.
No. 30 felt is thicker and stronger than No. 15 felt, making it more resistant to tearing during installation and better suited for general roofing conditions. It is commonly used as a standard underlayment choice for quality asphalt shingle installations. |
