 Trustindex verifies that the original source of the review is Google. 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!

 Trustindex verifies that the original source of the review is Google. 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.

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!

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.

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!

 Trustindex verifies that the original source of the review is Google. 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.

 Trustindex verifies that the original source of the review is Google. 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.

The grid went down again. Your panels are right there on the roof, soaking up Texas sun, and yet your house is dark. That is the part nobody warns you about. A standard grid-tied solar setup shuts itself off the second the power fails, so your panels can’t keep you running during an outage. We fix that by adding battery storage that holds your solar energy and keeps your essentials on when ERCOT can’t.

Katy homeowners deal with summer heat waves, hurricane season, and a grid that keeps getting squeezed. We install battery backup the same way we handle every roof in this area, with honest advice and work we stand behind.

When You Need a Solar Battery Backup

If you already have solar panels but still lose power every time a storm rolls through, that is the clearest sign. Grid-tied systems are built to disconnect during outages for safety, which means sunshine alone won’t keep your fridge cold or your AC running.

You also need storage if your home depends on power that can’t just stop. Think well pumps, medical equipment, a home office, or keeping food from spoiling during a multi-day blackout like the one Winter Storm Uri caused. Rising time-of-use rates push some folks toward batteries too. Storing your own daytime solar and pulling from it during expensive peak hours can soften the bite of a Texas electric bill. A solar energy system service in Katy TX can help you determine whether battery storage makes sense based on your energy use, outage concerns, and long-term goals.

Our Solar Battery Installation Process

A solar battery install starts with a site visit. We look at your electrical panel, your existing solar setup if you have one, and the loads you most want to keep running, then size the battery to match.

From there comes the design and the paperwork. That typically includes the electrical plan, the local permits, and the utility interconnection request, so you aren’t stuck chasing approvals on your own.

On install day the battery gets mounted, wired into your panel, and connected to a hybrid or AC-coupled inverter depending on your system. Most installs wrap up in a single day, and a good crew tests everything, sets up your monitoring app, and walks you through how it works before leaving.

Solar System Battery Installation Cost in Katy TX

Pricing varies a lot, so treat these as general Katy-area market numbers rather than a quote. A fully installed home battery system commonly lands between $13,000 and $22,000, and that range moves with capacity, brand, and how much electrical work your home needs.

Size is the biggest driver. A single battery covering essential circuits still runs many thousands of dollars installed, while whole-home backup with multiple batteries and 30 to 40 kWh of storage can climb past $22,000. Older homes that need a panel upgrade or new wiring push the total higher still.

One thing worth knowing for 2026: the 30 percent federal residential tax credit expired at the end of 2025, so cash and loan buyers can no longer claim it, and Texas has no statewide battery rebate. We’ll give you a clear, upfront quote so the number you see is the number you plan around.

Frequently Asked Questions (FAQs)

1. Do solar batteries work in Texas heat?

Yes, but placement matters. Batteries do best in a temperature-controlled spot like a garage or shaded utility area, which helps protect them from Katy’s 100-degree summers.

2. How many batteries do I need to run my AC during a Texas summer outage?

Air conditioning draws a lot of power, so backing it up usually takes two or more batteries totaling around 30 to 40 kWh. The right system gets sized around the exact loads you want covered during an outage.
