"Very professional company to work with. Was having leaks over the years after multiple handy man repairs, but those usually dont last especially after the hurricane we just had. When it was time to re-roof, I came across Clear View. Communication was excellent. There was not a single time someone didnt answer my call or call me back ASAP to answer any questions I may have had. Their price was right in line with the other estimates I had received, so it really came down to who can provide me with the most trustworthy work. They were on top of the project from start to finish, and completed the job exactly when they projected. Ive already recommended them to my neighbors and family members, Overall, I would work with them in the future. Definitely"

"Corey was able to come and resolve our issue in a timely manner. Best way to communicate is through a phone call. Leave a message if it's not answered and they will get back to you as soon as they can. Had a leak in my roof that kept springing up. He had someone come look at it the same day, and they're able to patch it up just before the rain. I'm grateful for the quick resolution."

"Excellent service and quality work; Tore off an old 40-year roof and replaced and repaired plywood/fascia; installed new torch down roof. Oscar's crew showed up ready to work and got the job done before the rain started. Cleaned up and removed old tv cable wiring and left everything in top shape. Charged a fair price, and provided a very professional job! Highly recommend this company."

"Overall they were quick to respond, set up estimate, and once booked was able to perform work within a few days (after 72 hour contract signing). Francisco was very up front and honest. The two gentlemen that came to do the repair work were very nice and answered any questions I had. Couldn't asked for nicer people. Their customer service skills were top notch as well as the work they performed. My only reason for 4.5 stars was they were a little bit late but not drastically and I had to call the office to make sure they were still going to show up. Again once they showed up they got right to work and did a wonderful job. I've already given their name and number to a friend of mine for her to get an estimate on her house. If I need more work done or once I need a complete roof replacement, I will be calling them."

"a top notch professional, timely job, with a fair price. I had a few leaks on my flat roof during all the rains and Adrian did a great job taking video of the roof issues I was having & providing video with the quote, then took step by step videos to show me the repairs being done. Very pleased with this service, and customer interaction, very timely. He explained the potential future issues I could expect with my 20 year old roof, but did not pressure to upsale me on something I didn't need right away. I will look to him when I do get ready to replace my whole roof. I am picky, an extreme do it yourselfer, an Engineer, and it's hard to find something involving a house I don't have a pretty good knowledge about, but I was impressed with this company and discussing roofing and best practices that suited my needs. Very happy with their work. -18Dec2019"
