Cost-Effectiveness of Asphalt Shingle Layovers vs. Tear Offs
What’s everyones take on asphalt shingle layovers?
I know best practice is to do a tear off. But say you have a client that has one layer of architectural shingles on a 4/12 hip roof at the end of their life, but not terrible.. needing to be replaced on a budget.
Inspecting the sheathing from the attic shows some water markings around the normal places.. vents, stack, chimney. But nothing terribly rotted.
Can this work out okay.. or is this a bad idea for down the road?
