The roof looks amazing and the quality of the work is very noticeable. Hailey provided outstanding customer service and kept us informed throughout the entire project. Highly recommend them!"

"I reached out to Apollo Roofing for an estimate because I had persistent leaks during the winter. I had called several roofers to get quotes for myself and my husband. Apollo?s estimate was the most reasonable price, and it didn?t compare to any of the other companies we contacted. Sam provided an estimate quickly, efficiently, and was incredibly professional and knowledgeable about roofs. We decided to go with Apollo Roofing, and it was the best decision we?ve ever made. We love our new roof, and we haven?t had any leaks since we had it installed."

"Tesla came by and said that I need a new roof before they can install the solar. Jacob was referred to me and came by the next day and helped me a lot to understand the roofing system to install leak barrier under roof to seal the screws drilled in"

"We recently had our roof replaced by ODR Roofing, and I couldn’t be happier with the experience. From the start, communication was excellent—Oscar was incredibly helpful and kept us updated at every step of the process. He took the time to explain our options, gave thoughtful recommendations, and made sure we felt confident in our decisions. The entire project was handled quickly and efficiently without compromising on quality. The workmanship was outstanding, and the attention to detail really showed in the final result. What could have been a stressful project turned out to be smooth and worry-free thanks to their professionalism and reliability. I highly recommend ODR Roofing for anyone looking for a seamless, high-quality roof replacement with top-notch customer service."

Roofing questions, answered by experts

While you technically can add a roof over shakes or shingles, it’s not a good idea. Roofing over existing roofing creates a moisture barrier underneath the new roof and since the trapped material is wood, you can expect a moisture problem. While you could get away with installing a new roof over asphalt or steel, wooden roofs should be removed, new underlayment installed, and the new roof installed over that. Also, the extra weight would add strain to your roof structure.

Whether or not the terms of your roofing estimate are negotiable depends on the contractor. Some professional roofers will be willing to budge on labor fees to some extent, while others will simply walk away from the potential work rather than lower their fees. In most cases, it’s best not to negotiate the terms, as lower labor charges could lead to your contractor cutting corners. Material costs aren’t negotiable, but you could purchase them yourself to try to save on delivery fees and markups.

There are several signs that indicate you’ll need new underlayment. Clear signs include missing or damaged roofing and exposing the underlayment to the elements. Additionally, if you notice water damage in your home by the roof after a storm, it could indicate that your underlayment may need to be replaced. If your gutters aren’t draining properly, it could also lead to rotting or water damage to the underlayment.

The best way to know if your roof can support solar panels is to hire a structural engineer. They’ll look at your roof and approve the design of your solar panel system or suggest changes. The best roofing for solar panels is made from strong materials like asphalt shingles and metal, but tile and gravel will work. Softer materials like thatch or temporary structures are not a good fit.

Yes, you have to get on the roof to cut a hole for solar tubing. It's not possible to complete the job from inside your house by simply cutting through the ceiling. So if you want to go the DIY route, remember to use safe ladder practices. If you’re not comfortable climbing on your roof to install solar tubes, hire a pro who has the tools and expertise to do the job safely.
