Frequently Asked Questions

Commercial roof leaks are commonly caused by weather exposure, aging materials, drainage issues, and general wear and tear. Problems such as ponding water, blistering, and damaged roofing membranes can quickly worsen without proper maintenance. Regular inspections from a professional commercial roofing company that CA businesses trust can help identify and resolve issues early.

Single-ply roofing systems are a popular choice for commercial properties because they are durable, energy-efficient, and cost-effective. Materials such as TPO and PVC offer strong resistance to UV rays, chemicals, and weather damage while helping improve energy efficiency by reflecting heat away from the building. Working with a trusted commercial roofing contractor that CA businesses rely on helps ensure proper installation and long-term performance. With routine maintenance, single-ply roofing systems can provide reliable protection and minimal upkeep for many years.

Yes. As an experienced commercial roofing contractor CA property owners rely on, we provide fast and dependable emergency repair services for both flat and sloped roofing systems. Our team works quickly to restore your roof and minimize damage to your property.

Flat roofs are especially vulnerable to standing water, UV exposure, and temperature fluctuations. Routine maintenance from commercial licensed roofers in CA can significantly extend the life of a flat roofing system and prevent costly repairs.

For commercial buildings with flat roofs, it is recommended to do an inspection at least once per year. This inspection should be done within the first year of the new roof. Regular maintenance on the roof is key to preventing problems with the roof and potential problems with the structure of the building.

Alex Pinelli
Peterson roofing was phenomenal for our commercial needs. Ben (the owner) personally came out for the initial inspection and beginning of the project to kick it off. The team was responsive, on time, and very professional.
Angela Alvarez
Great customer service and very detailed on the information I was given. They were on time and finished the job in a timely manner. Definitely will use again.
Linda Petersen
I had a flat commercial property roof that was leaking and contacted several roofing contractors. Peterson Roofing was by far the most responsive and professional in conducting an inspection and promptly providing a bid complete with multiple pictures along with three options for addressing the problem. I chose to squeeze a few more years out of the existing roof rather than replace and I was not pressured in any way to take the more expensive route. Ben, the owner, provides personal honest service and is a true professional. There is no doubt that I will return to Peterson Roofing for ongoing maintenance and eventually replacement. I highly recommend them.
Mike & Anna Dean

I highly recommend their service, they are trustworthy, responsible, reliable and fair. If they can get your job on the schedule I would say don't hesitate and do business with them, you will not regret it. They just completed a very challenging concrete building at 160Ft height... they overcame any and all obstacles/issues with this roof and went above and beyond to make sure all was 100% not just to my satisfaction but to their higher standard.

Dee Nietschke
We have a mini storage business that was aging therefore in need of a roof coating. We didn't have any leaks but wanted warranty to protect our customers storage contents. They were very helpful and did a neat and tidy job caring for our customers during the process. We wouldn't hesitate to use them again.
Danny MacPhail
I’ve been working with been for about 3 years now and I’ve always appreciated his thoroughness and attention to detail. He provides quality service and has integrity in his field. He won’t try to “win the bid” nor will he tell you something needs repair when it doesn’t. I couldn’t more highly recommend.
Caroline Nunes
Ben and his wife, Sarah, were incredibly friendly and reliable. Our roof had begun leaking through our ceiling and from the first phone call to the in-person estimate to the repair was only about a week's time total. Both the estimate and the invoice included pictures of the work needed to be done and the repairs once they were complete, with a brief explanation of what the pictures were. Highly recommended!
Keith
Peterson Roofing has the knowledge and level of integrity that I trust to inspect, repair and install roofs for my clients and friends. I recommend them to anyone that has roofing needs. They will give honest answers regarding your roof and they do some of the best work I've seen. In addition, they answer your calls and show up when they say they will. If you need a skilled and honest roofing contractor, call Peterson Roofing.
Josh Letras
I'm a Realtor and one of the hardest trades to find honestly without price gouging, by far has been roofing. I met Ben a few years ago and that is all it took for me to start using him. He is responsive, honest and a delight to work with. He won't call it to be fix unless it really needs to be fixed. He has saved my clients HUNDREDS to THOUSANDS of dollars when other roofers gave astronomical bids. You won't regret calling Peterson Roofing!
Amy Badger
I have worked with Peterson Roofing often over the past two years in scheduling Roof Inspections for our Real Estate clients and have been THRILLED with the incredible job that they do EVERY time! Their reports are professional, detailed with pictures and have found issues that other inspectors have often missed. Ben is our go to Roof inspector because of the high caliber of his work and incredible prices. We are so grateful for the wonderful quality and value that he provides to our clients. I would highly recommend Peterson Roofing to anyone looking for a clear picture of the current state of their roof and a fair price to have it repaired.
Breana Trigueiro
I could not be any happier with the service that Peterson Roofing provides for my buyer and seller clients. Ben goes above and beyond, and I can always count on his honesty and professionalism in any recommendations and repairs he makes for my clients. Look no further for your roofing needs!
Marlinda Martins
Replacing my old shingle roof was a major undertaking so I took great care in selecting a company to do the job. Peterson Roofing did an excellent job and I’ve gotten several compliments on how well the new roof looks on the house. His workers were polite and kept the site clean at the end of every day. Ben and his wife were responsive to my calls and the job was done in the time quoted. I would highly recommend Peterson Roofing to anyone looking to replace an existing roof.
Brian Sturdivant
Every step of the way in the process of my roof tear off and dry rot repair couldn’t of gone any better. Ben is very communicative and was truly concerned about the amount of work that was needing to be done and the costs that come with that. That is when you know you picked the right roofing company. They did an amazing job and I will not have to worry about my roof for years to come. The crew did a great job and it was obvious they took pride in their work. I wouldn’t hesitate for a second to recommend Ben Peterson and his crew!!
Doug Higginbotham
Peterson Roofing is my go to for all roofing needs. Whether needing small repairs or large total roofing replacement, Ben and his crew always deliver excellent work with fair prices. Others might come in with lower prices but the work won't be the same quality.
Linda Bongatti
Ben is one of the most honest roofing contractors around. He is the only Roofing contractor I know that takes pictures to show where repairs might be needed. As a realtor, it is very important to have trust in contractors I recommend. Ben is the best in the business. I Would highly recommend to family and clients!! My clients love him!!
Terry Holliday
it was a pleasure to do business with them and would recommend them to others.
Don Wright
Easily the best quality roofing company in the Central Valley! Ben and his crew never let me down and I use him all the time. Peterson Roofing is always my number 1 choice for any of my clients. Their installs are the highest quality as well as their inspection reports. If you want cheap then Peterson Roofing isn't for you, but if you want quality and a long lasting roof then give them a call.
Jesus Pineda
Great work and very helpful. Would definitely recommend to any one looking for roof work.
Cara Baumgarte
Peterson Roofing is an amazing company. I’ve had the pleasure of working with them on replacing my roof on a home I just purchased. Mr Peterson had inspected my roof during the home inspection. He was very honest. His employees are top notch. I would highly recommend them for roof replacement or repair. Integrity and honesty is what this company is. By far the best company I’ve worked with on my remodel
Patrick Brinson
Ben and his crew were very professional and responsive from the start! They were prompt on answering questions in a way that I could understand, and even though they found more dry rot than I would have liked them to, I feel confident knowing that they inspected everything thoroughly and repaired it appropriately. Friendly quality service for a reasonable price!
Dale Andrews
Quality and Customer care are what these guys are all about. Start to finish my experience with Peterson roofing was too notch. The owner Ben is a super nice guy and very honest. Mike and the crew that worked on my house were some of the most professional individuals I have ever had work on my house. They did great work, very polite and left no mess what so ever. Over all a very pleasant experience and I’ll refer all my family and friends to Peterson Roofing.
Jennifer Pelter
Our old shingle roof was in sad shape. We called 4 different companies and Peterson Roofing was responsive, friendly and accommodating to our busy schedule. The owner came and met with us and checked out the current condition of the roof and talked us through the material options, the timeframes and what would be needed to ensure our roof was up to all code regulations and high-quality. We were given an estimated start date and ended up getting on the schedule early because they had an opening! The roof was completed in less than 7 days. The crew was friendly, professional and timely. The owner facilitated and managed the entire process pre-, during and post-, and provided updates throughout. I am beyond pleased with the service, professionalism and quality of our amazing new roof! I highly recommend Peterson Roofing.
