There was 1/2 a day before heavy rain and then snow was to come and we had leaks in multiple places on the roof. I swept the loose debris and dirt off and then sprayed the 50' running crack with CanSeal roofing. The great thing is Canseal Instantly sets and is actually waterproof right away. It rained hard a few hours later and CanSeal held just fine!
