我們剛收到保險公司的通知,在一個半月後 renew 房屋保險之前,要做 " Insurance company will want either (1) the roof cleaned or (2) an inspection by a licensed roofing contractor that addresses the discoloration in the inspection report.這房子的roof 有二十年了
(Discoloration is natural, occurs over time, and is usually not indicative of a problem. )
上來問問這種 Discoloration 的 roof cleaned 如何去做? 有contractor 能做嗎?
有經驗的房東給些 建議, 謝謝。
