    *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.

The associate who first came to assess our roof and give us a quote was super informative and respectful. There was no "hard sell" and he patiently answered all of our questions even though we were in the middle of other renovations and told him we wouldn't be making any decisions that day. He said "no problem" and sent us the quote to look over. Two months later we booked the job and were thrilled with the results. The whole process was easy and exactly what you'd expect from a good roofing company. They showed up exactly when they said they would, did a wonderful job and cleaned up before they left. Four years later our gutters started to leak. Mind you, this company sub-contracts out the gutter installation, so it technically wasn't their mistake. Specialist Roofing & Repair sent out a supervisor and fixed the issue-- no charge, no delay. All under warranty. They are a WONDERFUL company that does a great job and treats their customers with respect. Cannot recommend them highly enough.

From start to finish, the communication was excellent. They kept us informed every step of the way with regular updates, drone footage, and photos so we could clearly see the progress being made. The crew was professional, honest, hardworking, and respectful of our property. Their pricing was fair and competitive, and there were no surprises along the way. The quality of the workmanship exceeded our expectations, and the final result completely transformed our home. We truly feel like we now have the best-looking house in our community. If you're looking for a company that delivers quality work, clear communication, fair pricing, and outstanding customer service, I highly recommend Complete Roofing.

He was also very honest and laid out the various solutions that were available for my particular situation. I received a detailed estimate for each portion of the project. As soon as I gave Ron the green light, he got the city permit and everything finished well within the two week timeline I had. The roof passed the initial and the final city inspection. They sent a full crew of people to work on the roof which is one of the reasons why the work finished so quickly. Some useful context: I am in the midst of renovating my 101-year-old home and have had to work with many contractors and company over the past few years. Complete Roofing was one of the best companies I've worked with -- very helpful, honest, professional and fast. They also cleaned up around my home afterwards -- not all companies will do this :)

The pricing was fair and reasonable, the workmanship was excellent, and the entire project was completed surprisingly fast without cutting corners. What stood out most to me was the communication. Tony always answered the phone, kept me informed throughout the process, and was straightforward and easy to work with. In an industry where communication can sometimes be difficult, that really mattered. The crew was professional, efficient, and kept the job site clean. The finished roof looks fantastic. I would highly recommend Roof Land to anyone looking for roof repair or a full roof replacement.

They promised a proper torch-down roof and sealed flashings -- instead, I got leaks after every rain, 8 failed repair attempts, and a cheap silicone coating to cover up their mistakes. It's interesting they are admitting their poor job in response here and are proud in their "prompt repairs", but why does a costly new roof need many repairs (all of which failed)?! If I wanted repair I just had repaired my existing roof! The images clearly show the poor job in installing torch down layer by roof land. A licensed inspector confirmed the work was defective and incomplete. I've been left with water damage and no resolution after over a year of stress. Do yourself a favor -- AVOID Roofland Roofing at all costs.

It was clear that they were a group of roofers who took pride in their work. * Installation was a key element of all that happened each day they were on the job - on the roof! In spite of the intense heat they pursued a course of integrity. * When I asked about the possibility of insulation Sean provided an excellent Low-e solution. We have a vaulted roof - no room for R30 to be laid in. So when Sean presented the Low-E Therma Sheet as a roofing underlayment, I was especially pleased. This CA "Cool Roof" alternative insulator is a reflective guard against the intense effect of the Sun during SoCal summer months. What a great value! * Another element that I appreciated was the high level of secondary contractors Sean included on his team. Tony was the HVAC contractor who walked us through all the issues in moving AC units so that the roof underneath could be properly addressed. * This critical area was of concern to many of the residents in our HOA. I appreciated the personal attention and quality work in taking care of our AC unit. * We received a 20 year warranty on the roof and a certification of cool roof installation. The cool roof application came with a rebate through IRS form 5695. DWP has a rebate which Sean alerted us to. * What a great value to receive such a quality roof from people who carefully serviced our requests. Were there problems along the way? Of course! But in each case I had personal access to Sean who always took time to listen and then act on our behalf to resolve. Excellent service!

They worked fast and left almost no mess -- I walked all the way around the house afterward and found very few nails or leftover shingles.

Look at this beautiful new roof -- we're thrilled with the results. Highly recommend Sean and One Stop Roofing!
