Experienced roofers and facilities managers know mold on flat commercial roofs can degrade the roofing system and bring health risks. But while mold is a persistent problem for many roofs, this blog shows how Progressive Materials’ silicone coatings can resist mold on your roof.
Dangers of Mold
Mold thrives in environments with moisture, warmth, and organic material. Flat commercial roofs, especially those with poor drainage, provide optimal conditions for mold. Standing water can pool on the roof, creating a damp environment that encourages mold and mildew growth. Mold not only damages the roofing materials but can also seep into the building. This can cause health risks for employees or tenants because of poor indoor air quality.
Additionally, mold can degrade the roofing system itself. The organic matter that mold feeds on can break down roofing membranes. This can lead to leaks, cracks, and weakened areas in the roof. If left unaddressed, mold and moisture problems can result in costly repairs and disruptions to business operations. It can even bring potential litigation if health issues arise because of poor indoor air quality.
But what if mold has nothing to adhere to in the first place …
PM Resists Mold Growth
PM silicone roof coatings provide superior protection against the factors that contribute to mold growth. Here’s are some ways that silicone coatings help prevent mold:
- Inorganic Chemistry
Organic materials like wood and fabric can provide nutrients for mold growth. Being inorganic, silicone doesn’t provide an organic material source for mold to feed on. This means the mold has nothing to adhere to. Mold thrives on organic substrates, so the fact that silicone is made of inorganic compounds makes it inherently resistant to mold.
- Waterproofing Protection
Silicone coatings form a seamless, waterproof barrier on the roof. Unlike traditional roofing materials that can develop cracks and gaps over time, silicone coatings create a continuous membrane that prevents water from penetrating the roof surface.
- Moisture Resistance
Silicone coatings are highly resistant to moisture. Even in areas with high humidity or frequent rain, silicone coatings help keep the roof dry. Unlike other materials that can absorb moisture, silicone repels water, ensuring the roof stays dry and mold cannot take hold.
- UV and Weather Resistance
Silicone coatings can withstand harsh environmental conditions, including UV rays and extreme temperature fluctuations. This resistance helps prevent cracks, tears, or other damage that could create gaps where mold might grow. By keeping the roof in optimal condition, silicone coatings also reduce the need for costly repairs that might expose the roof to further moisture problems.
Conclusion
We’ve shown here that mold on flat commercial roofs is a significant problem that can result in damage and health risks. However, silicone roof coatings can be an effective solution. From their inorganic chemistry to creating a moisture-resistant barrier, silicone coatings resist mold growth. In a case where dirt builds up on a silicone roof, offering a breeding ground for mold, a simple power wash can wash off the debris, thus washing off the mold. Since the mold cannot grow into the silicone, it will wash away with ease. Investing in silicone roof coating is not just about improving the roof’s longevity; it’s about ensuring a healthier environment for those who work or live inside the building.
