Cosmic Renovation & Roofing reviews

Gareth hired Cosmic Renovation about two years ago to replace the Spanish-style tile roof on his home. He found their sales approach refreshingly straightforward — they walked him through the process and details without the pushy upsell other companies tried, and their price landed in the middle: not the cheapest, but fair for what they promised. Their project manager, Blake, guided the job and kept Gareth updated at every stage, which made the whole process easy to follow. The value showed up in the workmanship: two years on the new roof is holding up exactly as intended. What stuck with him most was the combination of clear, pressure-free explanation and steady communication from Blake — plus a roof that still performs two years later.

Mae on Mars owns an 80-year-old house and discovered a leak running from a near-rooftop patio down into the dining room wall. Ben came out, assessed the damage, and warned that final cost would depend on what turned up once crews pulled up the patio flooring. It turned out to be messier than hoped, but Ben laid out a clear step-by-step plan and pricing, then scheduled separate crews for the demolition, waterproofing, drainage work, and reinstall. The team worked around her schedule, returned calls when issues cropped up, and kept the multi-stage job moving along faster than expected. Crews cleaned and hauled away debris after each phase, treated the house respectfully, and even handled her occasionally excitable dog with patience. The patio now looks repaired and she walked away confident the waterproofing is solid. The detail that stuck with her was that upfront clarity about scope and cost made a messy teardown far less stressful — she plans to hire them again for future projects.

Craig H. hired the company for what was pitched as a two-day, $8,000 job and quickly discovered things went very differently. He found that the estimator who gave the quote never climbed onto the roof despite promising to oversee the work. Instead two independent workers showed up who didn’t understand the full scope; after under four hours they declared the job finished while the estimator/foreman still hadn’t appeared. Craig had to call the estimator, then beg the crew to wait until the rest of the work could be explained; less than an hour later they left, and the estimator never checked their work. The company initially wanted the full $8,000; after an argument with the owner Craig pushed the price down to $6,270, with the owner insisting—rudely—that he should be happy the crew finished quickly. The lasting outcome: about two years later one of the two work areas is leaking again, leaving the failed oversight and the post-job dispute as the most memorable parts of the experience.

Tarell bought his house about a year ago and discovered it needed a new roof and attic insulation, so he called Cosmic Renovation and Roofing in Concord, CA. He connected with a helpful phone rep named May who smoothed out the scheduling, and a friendly crew showed up to clean the attic, install new insulation, and replace the roof. The team left the jobsite tidy and the work completed as promised; what stayed with him most was May’s assistance on the phone and the crew’s thorough attic cleanup before installing the insulation.

May owns an 80-year-old house with a nearly roof-top patio that started leaking into the dining room wall below. She discovered the problem and brought Ben in, who assessed the situation and was candid that the final price would depend on what showed up once the patio flooring came up. Once the team tore into the patio they found a mess, but Ben explained the multi-step repair, spelled out pricing for each stage, and organized separate crews for demolition, waterproofing, drainage, and reinstall. The crew worked around her schedule, Ben returned calls promptly when issues popped up, and the whole staged project moved along faster than she expected. Each team was polite, cleaned and carted away debris after every phase, and even handled her occasionally annoying dog with patience. The patio now looks good and she feels the waterproofing is solid; she plans to hire them again for future work.

Tony J. started out pleased with three bathroom remodels on his ranch-style home—enough that he praised the job lead—but the project unraveled over follow-up work. He discovered the team didn’t consistently meet standards, though the lead would send them back to fix things he called out. The turning point came when the job failed a building inspection for a simple, non-dangerous electrical issue; over the next two years he chased broken promises as May and Jennifer repeatedly delayed completing the correction. Frustrated, he filed a complaint with the State Contractors License Board, and only after that complaint did the company rapidly get the electrical work done to clear the case. Separate grout problems had already shown up around a tub and floor where caulk should have been used; Cosmic eventually attempted repairs more than a year after the original work, but the tile technician then went beyond the brief—smearing grout across both bathroom floors in the wrong color and leaving a multicolored grout mess. That botched repair remains unresolved, so he ended up with a project that required regulatory intervention to finish and a cosmetic fix that made the bathrooms look worse.

Bert T. needed a tile roof repaired on his home and contacted Cosmic to handle it. They addressed the problem promptly, charged a reasonable price, and sent a professional crew that completed the work correctly. He appreciated the quick, affordable fix and plans to hire them again for future projects.

Dushun chose Cosmic Renovation & Roofing for a residential roofing and home-improvement job after the project manager, May, stood out during the sales process. May’s persistence in getting timely answers, returning calls when promised, and combining professionalism with a personable approach won him over and left him feeling like a client rather than an unpaid project coordinator. The roofing crew matched that standard: they arrived on time, worked professionally, and coordinated smoothly with other contractors so the job got done right the first time. The whole experience felt straightforward and well-managed — and the practical takeaway for anyone calling them is simple: ask for May, who kept schedules, communication, and contractors aligned throughout the project.

After the company replaced her roof, May discovered the workmanship was shoddy: crews arrived who didn't know Zaki, the owner, and she never met the project manager. The workers appeared to be unlicensed, roadside hires, and when the roof began leaking in over 15 areas she ended up in arbitration with an individual named Jennifer who pushed through a ruling that blamed a window for the damage. Jennifer’s solution required buying more than 40 windows from the same company as the only fix, a conclusion May labelled fraudulent. Later the company sent a lone worker to fulfill warranties; he refused to speak or allow photos, covering his face with his hands, then left without making repairs. The roof kept leaking, and as of 10-16-2025 the problem remained unresolved. The lasting image from her experience is stark: a roof leaking in multiple places and an arbitrator’s recommendation to buy dozens of windows instead of fixing the roof.
