Coverage & How Much You Need:
One roll is 36 in. x 72 ft. and covers 200 sq ft, or 2 squares, before lap allowances. For eaves or valleys, calculate the linear footage of the vulnerable area at 3 ft wide per course and allow for the manufacturer's required lap, so one roll typically protects roughly 60-70 linear feet of eave.
Fit and Compatibility:
Use with shingle and other steep-slope roof coverings, and pair with mechanical synthetic underlayment such as Titanium UDL50 over the remaining deck. Primer may be needed on certain decks per the manufacturer's instructions; sold separately.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
PSU30 is the classic choice for ice-and-water protection at eaves, valleys, penetrations, and chimneys - the self-sealing laps mean nails from the roof covering penetrate a bonded membrane, not a loose sheet. Roll it firmly and install within the manufacturer's temperature window for the adhesive to bond properly. On the open field, pair it with a mechanically fastened synthetic like UDL50 to keep labor and cost down.
The membrane surface can be extremely slippery - always wear footwear with good traction and use fall protection, and follow the manufacturer's temperature and priming requirements.
Order Titanium PSU30 peel & stick underlayment for watertight protection at your roof's most vulnerable areas.
