Alpine Roofing

I hired Alpine Roofing to replace the roof shingles on my house. The only reason I replaced the roof shingles was that some blew away in a wind storm, and I got scared it could lead to a leak. Up until this point, I never had a leak. I hired Alpine Roofing to replace the entire roof. I paid $3,700.00 as agreed in the contract. Since then, my roof has been leaking. It's leaking into the master bedroom via the ceiling light. It's also leaking into the garage. Luckily, I haven't had an electrical problem. I've complained numerous times, and they sent people numerous times, almost every year since they replaced the roof. They keep doing patch jobs. They won't show me any pictures. How many times am I supposed to call them back?

Can they just finally fix the roof as per the agreement? I'm scared that this is going to lead to other major issues, as I have expressed to them on numerous occasions. They just keep sending inexperienced people to patch up the previous person's mistake. I would like for them to redo the entire roof as per the specifications of the contract or issue a full refund so I can get someone more qualified to complete the work.
