Fastener-sealing eave protection is very helpful at the eaves and the valleys. If No.30 ASTM Type ll or No.30 ASTM Type lV roofing felt is installed on the remainder of the roof with a continuous ventilation product on top of the felt and eave protection you will have a great roof. If using a Certi-LastÂ® or shake felt system product you only need the felt and eave protection. What is the CSSB recommended procedure for base or sheathing protection? No. 30 ASTM D226 Type ll or ASTM D4869 Type lV roofing felt.
