Coverage & How Much You Need:
One roll measures 22 in. x 120 ft. and covers 220 sq ft (1 square) laid flat. Allow for laps at eaves, hips, valleys and end laps, which reduce effective coverage, so order slightly more than the nominal roof square. The 22 in. width is convenient for horizontal courses on shake and shingle roofs.
Fit and Compatibility:
Install under cedar shakes, wood shingles, asphalt shingles or tile as the primary underlayment layer. Fasten per the roofing manufacturer's instructions; cap nails or standard felt laps per code apply.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
A 30# organic felt like this VulcaSeal roll is a dependable, code-recognized choice under shakes and shingles where a heavier felt than 15# is desired. The 22 in. width lets you run a clean course layout typical of shake roofs. Account for lap loss and weather exposure limits; felt should be covered promptly after installation to keep it flat and dry.
Handle rolls carefully to avoid back strain on the roof, and install underlayment only in dry conditions per manufacturer instructions and local code.
