Wanting to get some feedback on the topic of ridge cap directions for asphalt shingle roof coverings. It’s always been my understanding that you determine ridge cap direction by evaluating where the prevailing wind will most likely be coming from a majority of the time.
With that being said, I’m seeing a lot of homes in my area with ridge caps changing direction midway down the ridge. So they will have a center shingle and then fan the cap out in opposite directions from the center, almost seemingly for looks rather than functionality. Seeing this a lot on new construction as well. Am I missing something here? Is there some methodology behind that practice or is it just crews not understanding the thought process behind ridge cap direction?
