    Metal roof
    Morgan A.

    We used Factor for a pretty huge job that included installing more than 5,000 sq ft of metal roofing, extending the existing roofline, painting the house, and installing a ton of new fans and lights. I couldn't be happier with the results and Vlad and his team were a joy to work with.

    We hired Roofing Angels in late November 2025 to replace a leaking roof on our duplex, paid a…read more$1,000 deposit promptly, and what followed was nearly four months of delays, disorganization, and surprise charges. From the start, communication was poor. They repeatedly blamed permitting and city hall for delays, promising the permit was "always around the corner" and that we'd be first up once the new year started -- that never materialized on time. When heavy rains hit in mid-January and the leak was getting worse, I pushed them to tarp the roof in the meantime. They tarped the wrong unit of our duplex. The tarp was also done so poorly it was flying off the roof, and our tenant's unit continued to leak throughout. By mid-February they still hadn't broken ground, this time blaming the rainy season. Work only started after I pushed them again. Once the project was underway, the original estimate ballooned -- they came back asking for roughly $1,000 more for the solar work and additional roofing costs. We paid what we felt was fair and moved forward. The final straw: after they issued a "final invoice" and we paid it in full -- believing we were done -- they came back asking for an additional $3,250. They apologized for "any inconvenience" as if it were a scheduling mix-up, not a failure to communicate thousands of dollars in charges before issuing a closing invoice. The roof work itself may be fine, but the experience getting here was exhausting. Constant runaround, poor follow-through, a botched tarp job that made our tenant's situation worse, and financial surprises at every turn. We would not recommend or use them again.

    I had an excellent experience with Roofing Angels from start to finish. Ziggy, the project manager,…read morewas professional, attentive, and kept everything running smoothly throughout the project. He communicated clearly, answered all my questions, and made sure every detail was handled with care. The crew worked efficiently, kept the property clean, and delivered high-quality workmanship. The roof looks fantastic, and the entire process felt organized and stress-free. I highly recommend Roofing Angels and Ziggy to anyone looking for reliable, honest, and top-quality roofing work

    *Would Hire Again*…read more [Project Scope] Re-roof on a one story single family house, including new underlayment, drip edge, composite shingles, plus sheathing repairs and ventilation updates. FWIW, in my line of work we nit-pick over details & craftsmanship. I bring those expectations--for better or worse--to maintaining my house. Unsurprisingly, I tend to find some level of fault with any contractor. [Communication] The project manager (Danny) and front office (Melissa) were quick to answer the many questions I had via email, text, and phone. They were patient while I took my time selecting a contractor. They also coordinated directly with my solar contractor so the rooftop PV system was off the roof for no longer than necessary. The PM was out briefly each day to check the work and collect payment. [Availability] I didn't need the work done urgently, but Smart Roofing did start work within two weeks of signing the contract and finished within 3 days. [Warranty] One reason I chose this company was their standing as Owens Corning Platinum Preferred, which gets a workmanship warranty backed by Owens Corning (except the solar penetrations in our case), should the contractor ever go out of business. [Workmanship] Crews (separate tear-off and install) were on-time, respectful, and cleaned up each day. Overall, the work appears to be done well, though I'm no roofer. The way some of the holes in the roof were cut and flashings set did seem to be rushed, but so far it's watertight and that's what matters. The original sheathing had large gaps, which I asked to be fixed, although they may have done so without my asking, that wasn't communicated one way or another. They handled the addition of an exhaust vent flashing, relocation of a vent flashing, and removal of an unused vent flashing as per my request. [Issues] At some point, the furnace b-vent was pushed into the attic, breaking an elbow inside the attic. I ended up getting the part and doing the repair myself. Similar as well with the water heater b-vent: it was pushed down and crushed a section, but wasn't caught by the crew. Plus, the vent was reset at an angle so it's now pressed up against the house. Finally, while cleanup went fairly well, there was still trash and a few handfuls of nails scattered throughout the property, roof, and gutters--a small complaint and probably par for the course. Slightly-related... at no point did a Simi Valley building inspector come onto our property. For both inspections, a truck appeared across the street, yet no one got out. No looking at the back of the roof, no rooftop inspection, no check that sheathing was sound and work done correctly. What a joke, that $560 payment to the city. Thanks, Danny and crew, for the work!

Decided to do a full roof underlayment replacement, searched on Yelp and received 4 quotes with almost identical materials from 4 different licensed roofers. Quote from Evi at Smart Roofing is the lowest with a bit more coverage, and Evi always answered my questions in a timely manner. Eventually signed a contract with Evi, project started in March during the hottest week. Evi kept me posted on a daily basis, and their crews are friendly and hard working, cleaned up before leaving every day. 1st day to demolition, 2nd day for city inspection and material delivery, then it took 3 days to complete the installation of Westlake Royal TileSeal HT underlayment. Smart Roofing offers unlimited plywood and tile replacement as needed, and they do not subcontract, all crewmembers are employed by Smart Roofing. Evi brought company's insurance document along with different underlayment samples when coming for an estimate, my project is backed by 10-year labor warranty and 30-year underlayment manufacturer warranty. Need to wait for the rain season to see how everything holds up, many thanks to Evi and all the crewmembers.

One company didn't even bother to come out--just asked for measurements and sent a generic quote for basic Milgard windows. Another contractor did show up, but he was extremely pushy and basically demanded that I make a decision on the spot. He was also the most expensive of the three. Approved Contractor was the complete opposite experience. Their sales rep came out, took his time, was very relaxed and professional, walked me through all my options, and provided full license and insurance info. He left me with a written estimate and zero pressure. Their pricing came in right in the middle, but the service level made it the best value by a mile. Once my HOA approved the project, everything moved exactly on schedule. The windows were custom, and the team showed up within the four-week lead time they quoted. They installed all five windows in less than a day. They also removed the brand-new blinds I had just installed and put them back up perfectly--like they were never touched. Huge bonus. Communication was great the entire time. The installer met me in the morning so I could walk him through the space, and he called ahead before finishing so I could come back from the office, inspect everything, and sign off. The finished product looks fantastic. From the first phone call to the sales visit to installation day, the whole experience was smooth, honest, and professional. I'd absolutely recommend Approved Contractor Inc. if you're looking for quality window replacement without the pressure or runaround.

Since then I continue to experience bubbles, lifting, and flaking of my stucco and coating. They begrudgingly fixed the problem a few times.
