HM-HS140-I
Silicone Roof Coating
100% silicone-based HM-HS140 is a single-component roof coating designed to provide a durable, watertight, breathable, and weatherproof barrier. Resistant to natural weathering, HM-HS140 offers excellent performance and long-lasting protection.
This versatile coating can be applied directly to various surfaces, including spray-applied polyurethane foam, EPDM, PVC, aged acrylic coatings, concrete, asphalt BUR, granulated modified bitumen, metal roofs, and masonry walls. It demonstrates outstanding primerless adhesion to many substrates, as confirmed by ASTM D6694 testing standards.
Cost-Effective: Achieve the benefits at half the cost of a roof replacement.
Hassle-Free Installation: Simple and efficient application process.
Guaranteed Performance: Up to 20-year leak-free warranty.
Weather Resistant: Resists rain wash-off, against ponding water, providing greater flexibility during installation.
Eco-Friendly: Environmentally conscious solution for sustainable roofing.
Seamless Protection: Forms a completely seamless and durable membrane.
UV Resistant: Maintains performance without chalking or degrading under UV exposure.
Save Money:
Howell silicone roof coating costs approximately 50% less than a full roof replacement. Why?
No need for roof tear-off, cutting project time in half.
Requires only half the crew size compared to a replacement.
Half the time, half the crew, half the cost.
Effortless Installation:
Follow an easy three-step process:
Clean, prep, and coat.
In most cases, primers aren’t required.
The applied coating resists washing off during rain.
Exceptional Warranties:
Choose watertight warranties of 5, 10, 15, or 20 years for lasting peace of mind.
Environmentally Friendly:
PM silicone roof coatings offer multiple eco-friendly benefits:
Low VOC emissions.
Reflects up to 88% of UV rays, reducing energy costs and extending HVAC lifespans.
Prevents tons of roofing waste from ending up in landfills.
Can be recoated when needed, reducing waste further.
Seamless Protection:
Since most leaks occur at seams, a seamless coating eliminates these weak points. Routine maintenance will significantly extend the lifespan of the coating.
