Roofing Companies near Diamond Bar

“I was looking for industrial roofers who could take on a large project without turning it into a drawn-out mess. The building needed a roof replacement, and there were enough prior repairs up there to make the project messy from the start.

The team remained practical the entire time. They removed the old membrane, repaired damaged areas beneath, and installed a new low-slope roofing system with proper flashing and edge details. They also coordinated inspections and kept the rooftop access organized, which helped more than I expected. The work speaks for itself. The roof looks right, drains correctly, and gives me a lot more confidence than what was there before.“

“American West installed a new insulated roof and earthquake bracing for me on my Mother's home. They were very polite, well organized and efficient. My Mother said the roof has made the home much quieter than before. She hasn't had an earthquake yet so we don't know how well they'll work, but I'm sure, being Southern California, we'll have one soon enough. I know I feel better knowing she's protected now. I'm very happy with Kent, his crew and the job they did for us. I give them 5 stars.“

“True Life Savers! I honestly don’t know what we would have done without Fitzhauer Construction today.

We discovered an active roof leak in multiple rooms right in the middle of this massive Christmas storm, which the news has described as one of the most intense Southern California has experienced in many years.

I found Fitzhauer on Yelp and called them in a panic. Even though they were clearly at capacity due to the extreme weather, they were incredibly compassionate and managed to squeeze us in for emergency tarping to help mitigate the damage.

Ryan and Brian were absolute professionals. Despite the pouring rain, they went up on the roof and handled the emergency mitigation immediately.

What truly stood out was how patient, honest, and down-to-earth they were. Ryan took the time to walk me through their findings, showing photos of the areas of concern they identified, so I could clearly understand what was happening and why immediate action was needed.

It’s rare to find such a customer-centric, dedicated team willing to help during a crisis holiday weekend. They prevented what could have been a major disaster for my home. If you’re looking for a trustworthy roofing company that truly cares, look no further. Highly recommended.“

new plywood and fascia boards. A complete new solid structure. Our wants and needs changed daily as the roof was being repaired. For example, add this and that, please, and if Rudy can do it, he'll do it. There wasn't anything he and his crew couldn't do. Every add-on has a cost, and you get what you pay for with him. The main thing is that he's an honest person and treats his crew with respect! His crew is trustworthy and like all his other reviews. Yes, they clean up and use blower every day before leaving.
