Metal roofs are built to last, but in North Texas, even the toughest systems eventually show signs of age. Between UV exposure, hail, seasonal rain, and temperature swings, older metal roofs often begin to leak at seams, fasteners, and penetrations. The good news? You don’t always need a full replacement.
A high-quality silicone coating system can restore and protect your metal roof for many years — if it’s installed correctly.
As the owner of Shepherd Metal Roofing, I’ve restored dozens of metal roofs across Dallas–Fort Worth using approved silicone systems. Whether your roof is R-panel, standing seam, or another commercial metal profile, here’s what you need to know before choosing a Roof Coating Contractor DFW.
What Is a Silicone Metal Roof Coating?
A silicone roof coating is a seamless, waterproof membrane applied directly over your metal roof. Unlike traditional paint, silicone is a high-performance elastomeric product engineered to flex, stretch, and withstand long-term UV exposure.
Silicone performs best on:
- Aging R-panel roofs
- Standing seam metal roofs
- Metal roofs with seam leaks
- Metal systems with fastener back-out
- Roofs with minor surface rust
A properly installed silicone coating essentially gives your roof a new protective skin for a fraction of the cost of replacement.
Why Silicone Is Ideal for DFW Metal Roofs
DFW weather is brutal on metal roofing — heat, hail, and humidity wear these systems down over time.
Benefits of silicone coatings in North Texas:
1️⃣ UV Resistance
Silicone doesn’t chalk, crack, or degrade under extreme sun exposure — a huge advantage in Texas.
2️⃣ Waterproofing Power
Silicone stands up extremely well to standing water, making it ideal for low-slope metal roofs.
3️⃣ Flexibility
It moves with the roof during thermal expansion, preventing splits and seam failures.
4️⃣ Cost Savings
Restoration typically costs 30–70% less than full replacement.
5️⃣ Energy Efficiency
White silicone coatings reduce heat absorption and lower cooling costs in the summer.
The result is a long-lasting roofing solution that performs beautifully in DFW’s harsh environment.
According to the Metal Construction Association, coating systems are one of the most effective ways to extend the life of aging metal roofs.
Common Problems Silicone Coatings Solve
Before recommending a silicone coating, we evaluate the roof for issues such as:
- Fastener back-out
- Open or separated seams
- Rusted areas
- Cracked or dried sealant
- Failed flashing
- Minor panel dents
- Small punctures or leaks
A silicone coating won’t fix structural issues — but it’s the perfect solution when the roof is still sound but leaking due to age or weather exposure.

Choosing the Right Silicone Coating System
Not all silicone products are created equal. The coating you choose should depend on:
- Roof pitch
Low-slope roofs benefit from high-solids silicone.
- Roof condition
Heavy rust requires a rust-inhibitive primer.
- UV exposure
White silicone offers maximum reflectivity.
- Desired warranty
10–20 year warranties are available depending on coating thickness.

How a Certified Contractor Installs Silicone Coatings
Proper installation is everything. A cheap coating job will fail within a few years, while a certified installation lasts decades.
Here’s the step-by-step process for silicone metal roof coating restoration in DFW:

Full Roof Inspection
We identify leaks, rust areas, fastener issues, and panel movement.

Power Washing / Surface Prep
All dirt, oils, biological growth, and loose paint must be removed for adhesion.
Rust Treatment & Primer
Rust-inhibiting primer is applied where needed.

Fastener Replacement & Tightening
Any loose or worn fasteners are replaced with self-sealing screws.

Seam Reinforcement
We embed poly-mesh or butyl tape into seams and penetrations to strengthen them.

Flashing Repair
All vents, curbs, skylights, and edge flashings get resealed.

Silicone Application
Silicone is applied by roller or spray at the manufacturer-required thickness.

Final Inspection & Warranty
We document the installation and provide warranty paperwork.
How Long Do Silicone Metal Roof Coatings Last?
Depending on coating thickness and application method, silicone coatings typically last:
- 10 years at 20 mils
- 15 years at 25 mils
- 20 years at 30 mils
After that, the system can usually be recoated, giving your roof multiple life cycles.
This makes silicone coating one of the most cost-effective metal roof solutions in DFW.
