If it's like their other stuff they sell with installers they're contractors they work with, they charge a fee for coming out to give you the estimate, and the fee is applied towards the roof job. So it's a "free estimate " if and when you get the job done by them.
Lowe's has prefferd contracts, who will come out and give estimates.
Lowes does have companies that that they out work too
Not that I know of. However, they may have a qualified pool repair professional to recommend!
