Commercial Roof Replacement
The Reliable Commercial Roof Replacement Company in Orange County
The roof of a commercial building is vital to its structure. Like all roofs, however, commercial roofs can sustain damage, wear and tear due to aging, or weaken as a result of various factors. When this happens, your roof becomes more vulnerable to escalating damage.
For example, weakened seams might lead to pooled water leaking into the roof itself. Severe weather and high winds might take a harder toll on a roof that is already aging. And of course, every roof system type has its own projected lifespan.
While it is often possible to repair damage without replacement, there comes the point in every roof’s lifespan when a full replacement makes more sense than endless repairs. Perhaps there’s so much damage that repairs aren’t an economical choice. Or maybe the roof is nearing the end of its life cycle, and there are likely to be more and more repairs in the future. In both cases, it usually makes the most sense to pursue a commercial roof replacement, rather than try to push an aging or damaged roof past its life expectancy.
Call our Experts for a Free Replacement Inspection
If you’re wondering whether you’re ready for a commercial roof replacement, call our experienced Orange County commercial roofing consultants at Guardian Roofs. We’ll be able to address any questions you have and schedule an appointment to have your current roof inspected so that we can help you choose the right new roof system based on your needs, your business goals, your budget, and your time frame. We understand that a commercial roof replacement is a significant investment, so we will make every effort to guide you through the process step by step.
When is it Time for a Commercial Roof Replacement?
We don’t push clients toward commercial roof replacement versus commercial roof repair. Instead, we thoroughly inspect your building and your current roof. We want to make sure that if we’re recommending a full replacement, it’s the option that makes the most sense for you practically and economically.
For example, some aging roofs can be revitalized merely with a new roof coating. This will depend on the current condition of the roof, the type of roof system it is, and the structure of your commercial building.
Here at Guardian Roofs, every member of our team is highly trained and experienced in our industry. We know how to read the signs of easily repairable damage versus the indications that it’s time to invest in a full replacement. There are certain red flags that we look for, with some of the biggest and most recognizable being large cracks, significant leaks, or missing pieces.
Of course, there are also many smaller tells that might not be obvious to the untrained eye, but our team will catch them! If you’re noticing signs of damage to your roof, it’s important to give us a call as soon as possible. Damage to a roof can escalate very quickly into damage that affects your entire building. For instance, leaks can result in mold, fungus, or mildew throughout your building as moisture builds up. That’s not a risk you want to take.
Reliable Replacements
No matter what the style of roof system you have, or the materials used in its construction whether it be a flat roof, single-ply, or multi-family roof, we can take a look and reliably figure out whether a repair or a replacement is in your best interest. Whether your roof is large or small, modern or aging, sloped or flat, we have the knowledge and expertise you need on your side.
If you are considering a roofing repair or replacement, call Guardian Roofs today. We’ll be happy to answer any questions you have or set up an appointment.

My wife and I are so impressed. Thoroughly professional in every aspect! The timeliness was accurate from the moment we met Doug and then Diana and their follow up and follow through were outstanding!! The Crew were so clean and neat, showing … More up before their start time with complete respect and deference for our property. Quite frankly , we have never met or had a professional experience like this before. Each night they left the property clean as can be .... and took great pride in their work!! Such polite crew that we were delighted to see them daily.
Thank You Guardian!! KUDOS.
Everyone there deserves all the benefits and credit as they reflect your company's integrity and supreme work ethics.
Cannot recommend highly enough!! -
My home in Pasadena was built in 1896, and after it sustained significant wind-related roof damage following the Eaton Fire back in early January of 2025—a destructive wildfire that impacted nearby Altadena—I knew I needed a roofing company … More with the expertise to restore and protect a structure of this age. Guardian Roofs & Energy Solutions delivered at every step.
Although my home is a historic property, it is not an official contributor to Pasadena’s Historic Preservation Program. That said, Guardian approached the project with the same level of care, respect, and craftsmanship you would expect for a landmark building. They went above and beyond to ensure the structural integrity and historical character of my 125+ year-old home were preserved throughout the entire process.
Estimator Justin Sudduth was outstanding—he provided a detailed breakdown of the scope of work, including tear-off and removal of old roofing layers, radiant barrier sheathing, laminated shingle installation, upgraded flashing, new ventilation systems, and more. His communication was clear and proactive, helping me understand each phase of the project and how it would contribute to both performance and longevity.
What truly set Guardian apart was their ability to navigate the permitting process and coordinate with city officials, even ensuring appropriate documentation for the home’s age and significance. While my property wasn't subject to formal historic review, their commitment to following best practices in preservation and compliance was evident and deeply appreciated.
On site, Bill Scot, the operator, led a highly skilled and professional crew. They were punctual, respectful of the property, and maintained a clean, organized job site throughout. Bill’s oversight and communication ensured the entire project stayed on track and was executed with excellence.
Guardian didn’t just repair my roof—they honored the history of my home while strengthening it for the future. Their professionalism, attention to detail, and respect for both modern standards and historical elements make them an exceptional contractor.
If you’re seeking a roofing company that can handle complex, age-sensitive projects—especially those involving post-disaster recovery or historic homes—I wholeheartedly recommend Guardian Roofs & Energy Solutions. They’ve earned my trust and gratitude.

We just got a new solar roof from Guardian and I want to give a 5 star shout out to Carlos Castellanos and his team for the great job they did. They were on time and kept everything clean at the end of the day. They arrived with a smile … More and were a pleasure to work with. They were not scheduled to work the day the inspector came but Carlos felt it looked like rain so he coordinated with the inspector and came in the afternoon. He and his crew stayed until the roof was covered and it did rain that night. They came back the next day and finished the roof. Wonderful crew. It was a pleasure to work with them.

5-Star Review for Mario and Guardian Roofs
I cannot recommend Mario and Guardian Roofs highly enough! From start to finish, the experience was exceptional. Mario worked with my schedule, ensuring the project began at my convenience, and … More everything was done on time. The crew was professional, careful, and hard-working, leaving the site spotless each day.
What truly sets Guardian Roofs apart is their attention to detail and fairness. Their pricing was reasonable, and Mario was always available, promptly returning any calls or texts. They were the only roofing company that painted the replaced fascia boards at no extra cost—a small but impactful touch that shows their commitment to excellence.
Mario himself was personable, honest, and went above and beyond to ensure the project met and exceeded our expectations. He made sure we were completely satisfied before considering the job done.
Thank you, Mario, and the entire crew at Guardian Roofs, for the outstanding work! If you’re looking for a roofing company you can trust, look no further. They are the best in the business! -
Both my wife and I have been extremely satisfied with everyone from Guardian Roofs. Doug Hein is one sharp guy. My neighbor and I were so impressed with him that we both decided to get our roofs done after meeting with 5 different companies. … More
Mario was the superintendent responsible for the job and called me consistently to see how things were going and answered every question I had. Alex was my main contact throughout the job and arrived at 7:00 am everyday which I appreciated. He was very personable and I did my best to let him do his job. Whenever there was an area that had to be addressed, Alex would talk to me prior to changing anything without my permission. Freddie did a fantastic job of laying out the tiles and was very efficient and clean. My house was cleaned every day and I never had any issues. Mona Portillo along with Helen were great to work with from the office as well. As I mentioned earlier, Guardian Roofs went above and beyond my expectations!! Thank you for making us very happy.
