Commercial roof coatings are essential to extending the lifespan of a roof by protecting it from elements like sun, rain, and pollutants. However, improper application, subpar materials, and inadequate preparation can lead to premature failures, leaving the roof vulnerable to damage. At Rainstoppers Roofing in Charleston, WV, we specialize in quality roofing services designed to maximize roof durability and performance.
1. Insufficient Preparation and Cleaning
One of the most common reasons commercial roof coatings fail is inadequate surface preparation. Roof surfaces need thorough cleaning and inspection before applying any coating. Dust, grime, or even small debris on the surface prevents the coating from properly adhering, causing early peeling or bubbling. Additionally, all seams and flashing areas should be treated with flashing-grade coating before the primary coat is applied, ensuring complete and secure coverage.
Key Insight: Studies show that up to 50% of coating failures stem from improper preparation.
2. Application Errors: Moisture and Incomplete Coverage
Coating a roof requires strict adherence to application guidelines. The roof must be completely dry before coating because any moisture can cause the coating to blister or peel. Additionally, coating application should be uniform, forming a monolithic (seamless) membrane across the entire roof. Coating around structures, rather than underneath, can leave gaps, allowing moisture infiltration and faster deterioration.
3. Choosing Low-Quality Materials
The quality of coating materials directly impacts the longevity of a commercial roof. While some building owners try to reduce costs by selecting cheaper products, these often lack durability and tend to degrade quickly under intense weather conditions. High-quality coatings are designed to withstand UV exposure, wind, and rain, whereas low-quality options may crack or delaminate over time, requiring frequent reapplication and increased maintenance costs.
Did you know? In the U.S., about 30% of commercial building owners experience coating failures due to substandard materials.
4. Inexperienced Installation Teams
The complexity of commercial roof coating requires skilled professionals. Hiring an inexperienced crew can lead to poor application and higher chances of error. Experienced roofing contractors are well-versed in manufacturer specifications, ensuring the coating is applied according to guidelines that maximize longevity and effectiveness. With an untrained team, critical steps may be overlooked, and shortcuts may be taken, ultimately compromising the roof’s protection.
Conclusion
Understanding the common reasons for commercial roof coating failures can help building owners make informed decisions that protect their investment. At Rainstoppers Roofing, we prioritize quality materials, expert preparation, and skilled application to ensure reliable, long-lasting roof protection.
