换房顶问题# Living

Tar and gravel roof隔热太差,想换成closed-cell foam roof,问题:
1)foam roof是不是经济实用的选择?有啥注意事项?
2)能不能在现有的房顶上直接喷上foam?貌似现有房顶不漏水。
3)在南湾要多少$/sq ft?
4)有没有靠谱的contractor推荐?
谢谢!

$8.5 looks good? 看来加州是啥啥都贵,啊---
roofing-installers.com (serving AL, GA, NC, FL, TX):
"A spray foam roof is also fairly inexpensive, especially for a commercial
roof product. We install this type of roofing for, on average, between $3.50
and $4.75 per square foot. "
