100% Silicone vs Elastomeric Roof Coating

🏢 Why We Use 100% Silicone for Commercial Flat Roofs (and Not Elastomeric)

When it comes to protecting a commercial flat roof here on the Gulf Coast, you can’t afford to cut corners. Between the brutal sun, heavy rains, and hurricane season surprises, your roofing system has to be tough—and stay that way.

At SJ&H Roofing, we specialize in liquid-applied commercial roofing systems, and we choose 100% silicone coatings over traditional elastomeric products every time. Here’s why.

💧 Elastomeric Coatings: The Problem No One Talks About

Elastomeric roof coatings have been around a long time. They’re marketed as flexible, reflective, and cost-effective—but here’s the truth most manufacturers don’t want to admit:

☠️ Elastomeric coatings break down when exposed to standing water.
Flat roofs always have ponding in certain areas—especially down here in Biloxi, MS. Elastomeric just can’t handle that kind of abuse.

☔ It washes off over time.
We’ve seen buildings where the white elastomeric was completely gone in 2–3 years. That’s wasted money, wasted time, and zero long-term protection.

🌤️ Sun + rain = bad combo for elastomeric.
UV rays cook it. Gulf Coast rain rinses it. It might look nice the day it’s applied, but it doesn’t last where it counts.

🦾 Why SJ&H Roofing Uses 100% Silicone Coatings

We don’t roll the dice with your building. That’s why 100% silicone is our go-to for commercial flat roofing systems.

✔️ Permanent ponding water resistance
Silicone holds up under standing water—period. You won’t see it washing off or blistering after a storm.

✔️ High reflectivity = lower cooling bills
Silicone reflects up to 90% of UV rays, which helps reduce heat transfer into your building. That’s money back in your pocket.

✔️ Flexible, breathable, and long-lasting
It expands and contracts without cracking. Plus, it doesn’t trap moisture—so your roof system breathes and lasts longer.

✔️ Low-maintenance and re-coatable
Need to recoat down the line? Easy. Silicone bonds to itself for a seamless, long-term solution.
