ice and water..

我没看到他们用ice and water, valley 就用两层underlayment, metal valley.
alpha1232022-07-19 18:33:43
难道ice water 覆盖所有roof?

好主意
borisg2022-07-19 18:37:40
we have snow here, the requirement is

肯出钱就覆盖整个房顶!
alpha1232022-07-19 18:50:41
Deck + underlayment + ice water + shingle? , 其实没必要吧
alpha1232022-07-19 18:51:11
Valley 处用ice water 就行吧。
hhtt2022-07-19 18:57:41
Deck + ice water shield + shingle.
hhtt2022-07-19 19:04:45
我这建议是根据你这两层Felt Paper,所作的建议,与其两层,那还不如直接全铺Ice Water Shield?
alpha1232022-07-19 19:05:58
你们是wooden deck, 我那用的就是ply wood deck,
alpha1232022-07-19 19:06:47
Ice water 贵呀, underlayment 便宜哪。

我的屋顶就是这样的,铺满了deck, 前屋主弄的。但是,现在我要换屋顶了,不知该怎么办

在valley出用e and water shield ,满足SWR也会显示在wind mitigation 报告上
alpha1232022-07-20 00:12:14
什么是SWR
Hebe201801012022-07-20 11:41:24
Secondary water resistance
