Legal Question in Consumer Law in Massachusetts

Unfortunately, it is possible that unless you retain a lawyer to make the warranty claims, the roofer, manufacturer, retailer, etc. will continue to point fingers at one another, whether or not their positions are valid. The good news, however, is that consumer protection statute likely apply here, under which you could make forceful warranty claims and possibly recover your attorneys' fees, and even double or triple your actual damages. If I were you I would hire an attorney to write and send a strong demand letter insisting the warranties be immediately honored, and reserving all rights to multiple damages and recovery of attorneys' fees.

I have handled these cases many time before; If you are interested in discussing your options, feel free to contact me directly, without obligation to you.
