万能的房坛,请教南加州 flat roof 已经20年了,补过几次漏雨。如果想装太阳能板, 是必须要重新换roof (报价$33000), 还是整个coating一层就可以($22000)?谢谢
about roof during whole life of solar panel (at least 20 years).
I thought coating Is only for shingle roof. must be large house.
我觉得都好贵
Slope roof 不仅仅是外观与功能,是改了受力结构,需要structure engineer评估;4,你原来的平顶也可能有HOA/building 的 高度限制而导致。
用PVC。
