  Alex came out and gave us an estimate and explained the process from start to finish, easy to understand. They also rebuilt and painted the wooden structure around the chimney. Highly recommend LB Harbors

  My roof needed a lot of structural repair so even though it was a lot of money their base price was fair and I felt it was money well spent. Just as importantly, I felt I could trust them with their communication and professionalism.

  Fantastic experience with LB Harbors Roofing! Alex was quick to respond and scheduled the inspection right away. Jesus was professional, knowledgeable, and took the time to clearly explain everything and provide a fair, honest estimate. The crew showed up on time, worked efficiently, and delivered excellent workmanship exactly as promised. They kept everything clean throughout, and the final cleanup was spotless. The whole process was smooth, well-organized, and stress-free. Jesus even followed up to make sure everything was perfect. I’m extremely happy with the results and highly recommend LB Harbors Roofing!

  We did the whole house roofing with LB Harbors Roofing last May, and I promised to write good reviews if the roof has no leaking during the coming raining season, and it has no problem so far. So I give out a five star. Professional and well communication, Alex, thanks for your good job!

August is a great time to check if your gutters need cleaning. When gutters fill up with leaves and debris, water can back up and cause trouble for your roof and foundation—especially once the seasonal rains arrive. We recommend booking a gutter cleaning this month so your home is ready. Clean gutters help water flow where it should, keeping your roof and foundation safe from damage. Reach out if you'd like to schedule gutter cleaning or have questions about your roof. We're always here to help.2 days ago
