I can’t say enough good things about Josh, Jacob, and the team. From the beginning, they were professional, responsive, and genuinely cared about helping us through the process. Jacob did an excellent job communicating and the roofing work itself was done quickly and with great attention to detail. The whole experience felt honest and personal, not just transactional. What impacted me most, though, was the heart behind this company. In the midst of a challenging season for our family, there was a misunderstanding on my part regarding payment and scheduling. Instead of responding with frustration, Josh responded with incredible kindness, prayed about it, and chose to bless our family in a way we will never forget! Their work is excellent, but even more than that, they lead with integrity, compassion, and generosity. It’s rare to find people who care this deeply about serving others well. We are incredibly grateful and would wholeheartedly recommend them to anyone needing roofing work done!

Worked with them in February on replacing a roof that was losing granules and had a couple spots binding up showing signs it need replaced in the next year. Were able to work with them on pricing to match comparable quotes. Were quick to mobilize once I wrote a check. Install took less than a day, covered yard well (only have found one or two nails in the driveway by where the disposal trailer was) Repaired/re-caulked a couple spots inside without even asking (one was a stray nail shoot into drywall ceiling and others were probably cosmetic prior from settling). Followed back up with any concerns, made sure malarkey warranty paperwork was completed and delivered.

Great and very prompt service! It was very easy to set up an appointment online, and I received emails and texts confirming the appointment. Polite and friendly, and I was sent before and after pictures of the roof work they did! 10/10!

Our salesman, Andrew Garay, and his crew, did a great job with our roof replacement. We have know Andrew for many years from our association with our children’s school, Faith West Academy. Coach Garay spent many years helping young people mature. We highly recommend Andrew for your next roofing project.

Andrew was my point of contact for this whole deal and I’m so glad I got him! Down to earth type of guy and very easy to communicate with. Their entire process was very easy to follow and the pricing was very upfront. They definitely give off a local company looking to provide for their community. Installation day was seamless, guys showed up and immediately got to work. Roof and the vents they installed looked great! These guys will go above and beyond for you if needed and that will always be appreciated by this guy! I would 100% recommend RTU to anyone looking to get ANYTHING roof related looked at!

RTU arrived on schedule to perform our roof inspection, tune-up and installation of a solar roof vent. Took about 6 hours and everything on the proposal was completed. They removed all of the debris from around the house and provided pictures of the improvements. This is a professional group whose focus is to make sure their customers understand the project and then deliver on the agreed terms.

Selecting Roofing Technologies Unlimited for a roof repair in my home was an excellent decision. We found them Chat GPT when searching for a reputable roofing company that had favorable reviews. They recently completed the repairs and I want to recommend them as a company that not only does excellent work, but also as a company of great people of integrity. When Joshua came over to give us an estimate on the job, he immediately inspired confidence and trust that he knew what he was doing, could get the job done, and that he would do what he said. When we didn't know where to start, he took care of lining up everything that needed to be done. This was such a huge help to us. Character and trustworthiness are important to me, and I found these qualities in everyone I met in this company. Everyone was courteous and responded to all questions and requests in a timely manner. The repairs were done with professionalism and workmanship beyond my expectations. I recommend you consider them at the top of your list next time you need a new roof or any roof-related repairs.

Your electric bill climbs every summer. The AC runs nonstop, and that 100-degree Katy heat doesn’t let up. You’ve watched the number creep higher year after year. Maybe you’ve gotten a few solar quotes already and walked away more confused than when you started. The pitches sound great, the numbers don’t match each other, and you can’t tell who’s being straight with you. That’s where we come in. We install solar panels for Katy homeowners, and because Roofing Technologies Unlimited is a roofer first, we know how to mount your panels with your roof in mind.

When Solar Makes Sense for Your Home

The clearest sign is a summer electric bill that keeps growing. If you’re running 1,100 kWh a month or more in a 2,500 to 4,000 square foot home, solar starts to pencil out faster than most people expect. High usage is what makes the math work in your favor.

Your roof matters too. A south or west-facing slope with good sun and little shade from oak trees is close to ideal for panels here. If your shingles are getting older, it’s worth thinking about the roof before the panels, since you don’t want to pull a system off in a few years to replace what’s underneath it.

Some folks are simply tired of unpredictable bills and want to lock in their energy costs for the next two decades. Others are planning ahead before a roof replacement and want both done together. Either way, if you’re spending real money on electricity in this climate, solar is worth a serious look.

Our Solar Panel Installation Process

We start with a free inspection of your roof and a look at your energy use. We’ll check the condition of your decking, your roof’s orientation, and any shading, then talk through what size system actually fits your home. You get honest answers, not a hard sell. A solar energy system service in Katy TX should start with your roof and energy needs, not a one-size-fits-all system recommendation.

Once you decide to move forward, we handle the design and the permitting. Most of the Katy area runs standard permits that take a week to three weeks, and we manage the paperwork and inspections so you don’t have to chase anything down.

Then we mount the panels, wire the system, and set up the inverter. Because we do the roof work ourselves, there’s no subcontractor coordination and no finger-pointing if something needs attention up top. We finish by walking you through the utility connection and how your new system works.

Solar Panel Installation Cost in Katy TX

Pricing varies a lot based on system size, panel quality, and your roof. Across the Houston and Katy market in 2026, residential solar generally runs about $2.50 to $3.50 per watt installed before any incentives. A common 10 kW system often falls somewhere in the $25,000 to $34,000 range, and larger systems sized to the average Texas home can run a bit higher.

Several things move that number. Roof complexity, steep pitches, premium panels, microinverters, and added battery storage all push the price up, while permits and inspections typically add a few hundred dollars on top. One honest note for 2026: the 30 percent federal tax credit for purchased systems is no longer available the way it used to be, so check with a tax professional before counting on that discount if you’re buying outright this year.

Texas still exempts the added home value from your property taxes, which helps the long-term picture. We give you a clear, upfront quote with the costs broken out, so you know exactly what you’re paying for before you commit to anything.

Why Choose Us

We’re a family-owned company started by two brothers, Joshua and Michael Keith, and we’ve served Katy and the Houston area since 2022. Our customers have left us a 5.0-star rating across 97 Google reviews, and we hold licenses TMEL #51954 and TECL #31888.

Being roofers first is the real difference for solar. A lot of solar outfits farm out the roof work, but we do everything in-house, so the roof and the panels stay with one accountable team. We know Gulf Coast heat, hail, and wind, and we install with that weather in mind.

We don’t do bait-and-switch pricing or pressure tactics. We give honest advice, solve the actual problem, and stand behind our work, because we’re building trust here for the long haul.
