Was clearing small trees at edge of hay fields. A small tree fell on my roof with the result that I have a few cracks in the orange roof above the top right work light. Cracks are not more than a 3-4 inches long. Given that the cost of a new roof is over $2K CDN I will not be replacing .... So I am looking for suggestions on most durable method to "fix" cracks to make waterproof and does not look too bad ... I am thinking of using epoxy and plastic weld. Any suggestion on type of epoxy or other method to patch up?
