Silicone Roof Coatings in San Antonio and Austin

Standing Water and Strong Sun: Where Silicone Earns Its Place

Silicone is the coating chemistry we reach for when a commercial metal roof in San Antonio or Austin holds water after rain and bakes in the sun all summer. It resists standing water and UV better than acrylic, but it is not right for every roof, and choosing it sets how the roof can be recoated from then on.

We apply silicone as part of a full metal roof coating system: rust treatment, primer, seam and fastener details, then the silicone field coat, with the roof in service throughout.

Why Choose Silicone Roof Coatings?

Silicone copes well with summer heat, strong UV and sudden downpours. What it offers:

• Ponding Resistance – Holds up where water sits on the roof after rain, conditions that soften acrylic

• UV Stability – Stays flexible after long-term sun exposure

• High-Solids Coverage – Goes on thicker per coat than acrylic, so fewer coats reach the specified thickness

• No Chalking – Resists cracking and chalking, though it holds dirt and needs washing to stay bright

• Seamless Application – Creates a monolithic barrier over your existing roofing system

Ideal Use Cases in San Antonio and Austin

Silicone coatings are best suited for:

• Low-slope metal roofs where water sits at end laps and gutters

• Metal roofs on buildings that cannot shut down for a tear-off

• Metal roofs that leak at laps and fasteners while the panels stay sound

• Roofs the owner plans to keep recoating with silicone

Flat membrane roofs are a different case. If the membrane is worn out or the insulation under it is wet, a coating only hides the problem, and a TPO recover or replacement is the better answer.

Our Silicone Coating Process

1. Comprehensive Roof Survey

   • Assess the roof’s condition, slope, drainage, and compatibility

   • Identify panels to replace and details to reinforce

2. Cleaning and Surface Prep

   • Remove all debris, grease, and biological growth

   • Power wash and prime if needed for adhesion

3. Metal and Detail Treatment

   • Seal cracks, flashing gaps, or seam issues

   • Reinforce penetrations and vulnerable edges

4. Silicone Application

   • Spray or roll-apply silicone to specified thickness

   • Ensure a seamless, ponding-resistant finish

5. Final Quality Control

   • Perform post-application inspection

   • Record the finished thickness and recoat guidance for your files

Silicone vs. Acrylic: Which is Right?

Choose silicone where water lingers and you are content to recoat with silicone in future. Choose acrylic on well-drained metal roofs where a cleaner, brighter finish matters; our page on acrylic roof coatings covers that side of the choice.

Why Total Cladding and Roofing?

A straight answer on chemistry — After more than 20 years on commercial roofs, we recommend silicone, acrylic or no coating at all based on the roof in front of us, not on what is easiest to sell.
