I am very grateful to Leandro and his team for their help with two roofing projects at my house. The results were truly satisfactory, and they were responsible, professional, and had very reasonable prices. I highly recommend them.

I had a roof leak in late 2024, and several companies quoted me thousands of dollars just to add sealant — without even going up on the roof to investigate. Leandro was completely different. He and his team inspected the issue both inside the house and on the roof, and even used a drone in addition to an in-person inspection to pinpoint the problem. They discovered missing ridge caps, pipe collars, kick-out flashing, and more. His team is extremely dedicated, thorough, and their pricing is excellent. I highly recommend Leandro and his company honest, professional, and detail-oriented from start to finish.

My gutters were fallen off. He cleaned and repaired the gutters, cleaned roof looks like a new roof, I will be calling this team again also will referring him to others. 😊 pleased with the service.

I am very pleased with Apper Construction quality of work, expert advice, and reasonable pricing. They replaced the roof and gutters. The work on the roof is complex work for it is multi levels and steep. They extended the gutters so that water from the highest roof level drops into another. They did the roof in one day and cleaned up the site. I recommend Elejandro for any size job.
