Customer's reviews

JCIS Inc did above and beyond what was required and maintained fantastic communications throughout the job. Juan and his crew were very professional, courteous, and kept me informed throughout the entire job. I highly recommend them for roofing and all the repairs that have to be done for the roof to be put on right. His contract was thorough and price was fair. No surprises. I couldn't have asked for anything more than what I got. Very grateful to Juan and his crew for their attention to detail and professionalism in wanting to do every part of the job correctly. I could not be in town for the work and Juan's photos, videos, and phone calls made me feel like I was observing the whole project. That was unexpected and super nice. ~ Ben B
We bought a Kaufman & Broad house (mass production and they only build to make it through the warranty period - then the next day fail). Our roof had several leaks this last winter and we also wanted to add solar. JCIS and Juan were contracted by the solar company and we could have not found a better roofing company if we tried to do it ourselves. We did a full roof replacement and it was scheduled to take 4 days. Juan and his team completed the full replacement and did repairs in three major areas of leaks in just 2 DAYS! The project was pretty crazy with a dumpster, tools, hoses everywhere, etc. and they left our property clean ( like nothing was done. The also added new venting for the attic to cool and painted all the new stuff to match the roof. JCIS was great and super happy with them. ~ Mike L
We used JCIS Roofing to perform a roof lift and lay in preparation of a solar system installation. Juan was the lead Supervisor of the installation crew. He along with the installers were very courteous and professional. Juan answered our many questions to our satisfaction and went into detail about materials used and how they would be installed. JCIS Roofing Manager, Julian, suggested a change to the design of the solar layout that in essence enhanced the aesthetic appeal of the solar panel layout. We were very thankful that JCIS had the ingenuity to make that change and give our solar project a much better appearance. Thank you JCIS for your quality installation and your experience that made our project so great. ~ K S
