"I recently used Cal Property Pros LLC for a roof cleaning, and I could not be more impressed with the service we received! From start to finish, Greg was professional, personable, courteous, and thorough. He arrived on time, explained the process in detail, and took the time to assess my roof?s needs. My roof looks brand new, and I can already see the improvement in its overall appearance. I highly recommend Greg from Cal Property Pros LLC for anyone in need of roof cleaning. He is reliable, trustworthy, and delivered fantastic results. Worth every penny!"

"Fred and his crew were professional. Showed up on time. Showed pictures of roof condition before cleaning. Fair price for services. Rated quality of work 4 stars only because I can't see roof after cleaning. I will hire them again"

"Avi's and his crew were exceptional with their customer service and craftsmanship. As an example to how Avi treats his customers, Avi called me Saturday night to say he would be over at 8:30 Sunday morning to tarp my roof knowing there was a 30% chance of rain on Monday. Note, I did not have to call Avi...he called me to let me know he was coming over to protect my home. Avi was always available for communication. When he wasn't on-site working with his crew, he would ALWAYS be available via text and cell phone. Avi was also professional when having to adjust his work around 3 other Contractors installing insulation, ducts and electrical work. There was always full cooperation and the project went smoothly. Avi and his crew paid close attention to getting my new flat roof to drain properly and after a recent rain, I went up on my roof just to admire how well the water found its way to the drains. His work work was exception and if I ever had another roof project, I would call Avi without hesitation."

"All work done as presented. However, final test will be the next big rain to see if the leak is fixed. I feel confident that it is fixed. George was the estimator and supervisor of the work. He has many years of experience in the field and comes across as trustworthy and competent. It was a pleasure to deal with him."

"Dana the owner has worked with me directly and taken care of multiple roofs for me. Each and every project I’ve brought to him has went so smooth from beginning to end. Great price, he and his worker’s communicate very well and have exceeded the expectations set before each install. Great company and great team. Recommend to anyone for any type of roofing needs."

"They worked hard removing all the finish and applying the first coat of stain and sealant. They have come back two more time to sand and reveal to ensure a smooth finish as requested. They are always on time. I would reuse their service Nice people
