My contractor re-used the existing flashings on my roof and after he finished installing the new shingles, he left! I’ve left several messages with the company and no one will come back to install new flashings. Shouldn’t that be included in the work?
If the contract didn't specify the installation of new flashings, it wasn't included in the original scope of work. Be sure that all items of work to be done are included in the contract before signing it.
