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.

(see the related link) the sun and it takes 225 earth days. It takes Venus about 225 Earth days (224.70069 days) or about 0.6152 Earth years to make an orbit of the Sun. That's a bit over 7 Earth months. Venus spins slowly clockwise as seen from its north pole, so the rotation period (Venus day) is actually longer than its year, taking about 243 Earth days.
