I have a ~1 inch crack from a middle edge up. Anyone fixed a small crack with success? I’m thinking drill a hole at the top of the crack to stop it and cover it with lap sealant.
I would go with Dicor its easy to install and easy to remove in a few years to reseal as it ages. Others may last a bit longer but are a real pain to remove as they age and they will. The harder it is to get the old stuff off the more risk of damage to roof or skylight.
