From standing-seam metal to reflective coatings, here are the roofing systems that cut cooling costs in the Central Texas heat - and what to look for when choosing one.
Which Roofing System Actually Cuts Your Cooling Bill?
If you are shopping for energy-efficient roofing options in Central Texas, the material you choose matters more than most contractors will tell you. Central Texas summers push attic temps past 150 degrees on a dark asphalt roof. The right system can knock that down significantly - and lower your monthly utility bill in the process.
At OSAAT Construction, we work with homeowners across Killeen, Harker Heights, Copperas Cove, and the surrounding area every day. Here is what we have seen work.
Standing-Seam Metal Roofing
Metal is the top performer for energy efficiency in hot climates. A standing-seam metal roof reflects solar radiation instead of absorbing it, and the air gap between the panels and the deck adds a layer of insulation. Christopher Navas, our co-owner, came from the metal-roofing manufacturing side of the industry - so we have direct distributor relationships that keep material costs competitive.
OSAAT is a Worthouse Certified Contractor, which means we install modular and standing-seam metal systems to the manufacturer's exact spec. That certification also backs the product warranty.

Reflective Roof Coatings
If a full replacement is not in the budget right now, a reflective coating applied over an existing commercial or low-slope roof can cut solar heat gain by a meaningful amount. We offer roof coatings as a standalone service - and we will tell you honestly whether your existing deck is a good candidate or whether a tear-off makes more sense long-term.
Architectural Shingles with Reflective Granules
For homeowners who prefer asphalt, today's architectural shingles are a step up from the 3-tab shingles installed on most Central Texas homes built before 2010. Many carry a 30-year rating and use granules designed to reflect more UV than older products. On every roof replacement we do, we pull the old material all the way to the decking - no overlay - so the new system performs the way it was designed to.
What to Ask Before You Choose
- What is the roof's current deck condition? A coating or new shingle over a soft deck is money wasted.
- Does your HOA restrict metal or specific colors? Some Central Texas neighborhoods do.
- Are you filing an insurance claim? Storm damage is often the trigger for a replacement. We walk you through the insurance process at no extra cost and meet the adjuster on-site.
- What is your timeline? We can tarp quickly and schedule around your schedule.

Frequently Asked Questions
What is the most energy-efficient roofing material for Central Texas?
Standing-seam metal is the top performer in hot climates. It reflects solar radiation, runs cooler than asphalt, and lasts significantly longer. Reflective roof coatings are a cost-effective option for existing flat or low-slope roofs.
Does an energy-efficient roof qualify for a tax credit?
Some metal and reflective roofing products qualify for federal energy-efficiency tax credits. We recommend confirming eligibility with your tax advisor, since the specific product and installation year both affect the credit.
How do I know if my roof needs a full replacement or just a coating?
We inspect the deck condition first. If the decking is solid and the existing surface is in reasonable shape, a coating can extend the roof's life. If there is rot, soft spots, or significant storm damage, a full tear-off to decking is the right call - and we will tell you which one honestly.
