Expert Verdict — Reviewed by the SuperArbor Pro Desk
A 30# felt is the traditional choice under wood shake and heavier shingle roofs because it adds a robust water-shedding layer. Keep the felt flat and wrinkle-free and fasten it sufficiently to prevent blow-off before the covering goes on. In high-wind areas follow your local code's underlayment lapping and fastening requirements.
Felt rolls can be slippery, especially with dew or frost; wear fall protection and slip-resistant footwear while installing.
Add Tarah Shakeliner 30# felt to your material list for a dependable underlayment course.
