Why Texans Love It:
- Reflects up to 90% of sunlight
- Can reduce roof surface temperature by up to 50°F
- Works well on flat and low-slope roofs
- Adds waterproofing benefits
Best For:
Homes and commercial buildings in Dallas, Houston, and San Antonio with flat or metal roofs.
2. Silicone Roof Coatings
What It Is:
A highly durable, moisture-resistant coating ideal for extreme conditions, like the ones you’ll find in Central and South Texas.
Why Texans Love It:
- Excellent UV resistance
- Handles ponding water well (great for flat roofs)
- Long-lasting with minimal maintenance
- Reflective enough to significantly cut cooling costs
Best For:
Flat commercial roofs or homes in humid areas like Austin and Corpus Christi.
3. Acrylic Roof Coatings
What It Is:
Water-based coating made from acrylic resins. Acrylic coatings are known for their bright white finish and cost-effectiveness.
Why Texans Love It:
- Very reflective (up to 85% sunlight reflectance)
- Affordable compared to other types
- Easy to apply and recoat
- Good balance between cost and performance
Best For:
Budget-conscious homeowners in cities like Lubbock, Midland, or Waco.
4. Polyurethane Roof Coatings
What It Is:
Tough and durable coating with strong resistance to impact and foot traffic—perfect for roofs that are walked on frequently.
Why Texans Love It:
- High reflectivity
- Ideal for hail-prone areas (hello, North Texas!)
- Strong adhesion to many surfaces
- Adds a protective layer to extend roof life
Best For:
Homes and buildings in storm-heavy areas like Fort Worth and Amarillo.
5. Aluminum Roof Coatings
What It Is:
A blend of asphalt and aluminum flakes that gives roofs a shiny, metallic finish and decent reflectivity.
Why Texans Love It:
- Reflects sunlight while sealing small cracks
- Adds a shiny finish that deflects UV rays
- Helps extend the life of older roofs
Best For:
Older homes in dry regions like West Texas need basic protection and reflectivity.
6. Bitumen-Based Reflective Coatings
What It Is:
A darker-colored coating that’s made more reflective by adding white or aluminum particles.
Why Texans Love It:
- Works well on existing asphalt roofs
- Balances cost with performance
- Helps keep older roof systems functioning longer
Best For:
Residential roofs in suburbs around Dallas or San Antonio with aging asphalt shingles.
7. Thermoplastic Roof Coatings (TPO)
What It Is:
TPO (thermoplastic polyolefin) coatings are popular in new constructions and commercial buildings due to their bright white appearance and energy efficiency.
Why Texans Love It:
- High solar reflectance and thermal emittance
- Resists dirt and chemical buildup
- Durable and energy-efficient
Best For:
Commercial properties in Houston, Dallas, and Austin need top-tier energy savings.
8. Cool Asphalt Shingle Coatings
What It Is:
A transparent coating is applied over traditional asphalt shingles to reflect more sunlight.
Why Texans Love It:
- Let homeowners keep their current shingles
- Saves on roof replacement costs
- Adds protection against heat and UV damage
Best For:
Homeowners across Texas are looking for an affordable way to improve energy efficiency without replacing the roof.
9. Reflective Metal Roof Coatings
What It Is:
Designed specifically for metal roofs, these coatings boost reflectivity and protect against rust and corrosion.
Why Texans Love It:
- Keeps metal roofs cool
- Prevents rust in humid or rainy regions
- Helps lower attic temperatures
Best For:
Homes and barns in rural parts of Texas, like the Hill Country or East Texas, where metal roofs are common.
10. Radiative Barrier Coatings
What It Is:
These are advanced coatings that reflect heat radiation away from the roof surface. Often combined with attic radiant barriers.
Why Texans Love It:
- Best paired with attic insulation
- Significant reduction in interior temperatures
- Ideal for areas with intense sun exposure
Best For:
Homes in South Texas and the Rio Grande Valley, where sun intensity is highest.
How to Choose the Right Cool Roof Coating for Your Texas Home
Step 1: Understand Your Roof Type
Flat roofs work well with elastomeric, silicone, or TPO coatings. Sloped shingle roofs may benefit more from clear reflective coatings or radiant barriers.
Step 2: Consider Your Local Climate
If you live in a humid part of Texas, go with coatings that resist moisture (like silicone). If hail is common, polyurethane is a better bet.
Step 3: Match It with Your Budget
Acrylic and aluminum coatings offer great performance at a lower price, while silicone and polyurethane tend to be pricier but last longer.
Step 4: Don’t Forget Rebates and Incentives
Many Texas cities and utilities offer incentives for energy-efficient roofing. Look for programs in Austin, Dallas, and San Antonio to offset the cost.
