俺的那個是啥Foam roof, 上星期叫roofing company come to see see.
說是到期要換新的roof, 推薦用:
1, tear off existing roofing and remove.
2. For flat areas, install a 28# fiberglass base felt attached to the deck,
install two layers of 11-14 fiber glass type IV finishing felts.
3. apply white roof coating
保用4年, 要價8,000刀 (2000 sq ft).
俺覺得貴啊, 這東西還是recoat every 2-3 year .
28 # fiberglass 是啥?
