Silicone & Acrylic Commercial Roofing Systems

A properly installed silicone roof coating can last between 10 and 20 years, depending on climate conditions and roof maintenance. Unlike traditional roofing systems that often require complete replacement, silicone coatings can usually be reapplied over the existing layer at the end of their service life. This “recoatability” means property owners don’t face the cost and disruption of a full tear-off. In Central Pennsylvania, where freeze-thaw cycles are common, silicone’s flexibility allows it to expand and contract with temperature changes without cracking. With regular inspections and basic upkeep, such as cleaning off dirt or debris that may compromise reflectivity, silicone roof systems can provide a reliable and cost-effective long-term solution for businesses looking to maximize roof performance while minimizing life-cycle costs.

Yes, one of the biggest advantages of silicone roof coatings is their ability to be applied directly over many common commercial roof types, including metal, TPO, EPDM, PVC, and modified bitumen. As long as the roof deck is structurally sound, silicone can serve as a restoration system rather than a replacement. This avoids costly tear-offs, reduces landfill waste, and minimizes downtime for businesses. Surface preparation is usually straightforward, requiring cleaning and priming in some cases, but it’s far less invasive than replacing an entire roof. For property managers in Pennsylvania, this makes silicone a practical upgrade option for aging roofs that still have good structural integrity but need enhanced waterproofing and UV protection. The ability to extend an existing roof’s lifespan while avoiding major disruptions is why silicone coatings have grown so popular among RTG Solution’s commercial roofing applications.

Yes, silicone coatings are highly reflective and help reduce rooftop temperatures by minimizing heat absorption. By lowering the surface temperature of a building, they reduce the strain on HVAC systems, especially during hot Pennsylvania summers. This energy efficiency can translate into significant savings on cooling costs over time, particularly for large commercial or industrial buildings with expansive roof areas. In addition, silicone’s reflective “cool roof” effect can extend the life of underlying roofing materials by reducing thermal stress and UV degradation. Some facility managers report energy savings of 15–30% after installing silicone coatings. While actual savings depend on the building’s design and energy usage, silicone remains one of the most cost-effective ways to improve energy efficiency and sustainability in commercial roofing.

Yes, unlike many other roofing materials, silicone is naturally hydrophobic, meaning it resists water absorption and ponding. This makes it an excellent option for flat or low-slope roofs that often struggle with drainage issues. In Pennsylvania’s climate, where heavy rains and snowmelt can create pooling water, silicone provides a protective barrier that doesn’t degrade or blister under standing water. This durability helps prevent leaks and extends the roof’s service life, making silicone coatings a superior choice for facilities with challenging roof slopes. Ponding water is one of the most common failure points we see  in commercial roofing systems at RTG Solutions, but silicone stands out by maintaining adhesion and waterproofing even under constant exposure. For business owners, this means fewer repairs, lower maintenance costs, and greater peace of mind during wet seasons.

Silicone coatings are known for being low-maintenance compared to other commercial roofing systems, but they still benefit from regular care. The most common task is cleaning the roof surface to prevent dirt and airborne particles from dulling the reflective “cool roof” surface. In Central Pennsylvania, seasonal debris such as leaves or snowmelt residue can collect and should be cleared to preserve reflectivity. Annual inspections are recommended to check for damage or wear at seams, penetrations, and flashing. In most cases, repairs are simple and additional silicone can be applied to restore waterproofing. Unlike acrylics or elastomeric coatings, silicone rarely needs frequent reapplication, which makes it cost-effective over the long term. With minimal upkeep, businesses can expect consistent performance and durability, making silicone an attractive option for property managers seeking dependable roofing with fewer headaches.

While acrylic and elastomeric coatings have their place in commercial roofing, silicone is often the superior choice in terms of durability and resistance to ponding water. Acrylic coatings may cost less upfront, but they tend to break down more quickly under standing water and may require more frequent recoating. Elastomeric coatings provide good flexibility, but they often lack the UV resistance and long-term waterproofing that silicone delivers. For property owners in Central Pennsylvania, where roofs are exposed to both intense summer sun and heavy snowmelt, silicone offers the best balance of performance, longevity, and energy savings. Though silicone coatings have a higher initial material cost, their extended service life, reduced maintenance needs, and ability to recoat without a tear-off often make them the more economical choice in the long run.
