What Are The Signs An Industrial Building Requires A Roof Coating?
Signs an industrial building requires a roof coating include visible rust, corrosion, and frequent leaks. These problems suggest the metal roof’s protective layer is deteriorating, compromising its integrity and waterproofing capabilities. Addressing these signs early with a high-quality roof coating can prevent further damage, reduce maintenance expenses, and enhance the building’s energy efficiency.
The signs an industrial building requires a roof coating are:
- Visible Wear and Tear on Metal Surfaces
- Water Damage Indicators
- Energy Inefficiency Signs
- Physical Damage to the Roof
- Ageing and Weathering of the Roof
- Structural Movement and Shifting
- Frequent Maintenance and Repairs
1. Visible Wear and Tear on Metal Surfaces
Visible wear and tear on metal surfaces, such as rust and corrosion, indicate the need for an industrial roof coating. Corrosion can undermine the roof's structural strength, making it more prone to leaks and other issues. Addressing rust early can extend a roof’s lifespan by up to 50%, according to the National Federation of Roofing Contractors (NFRC). Applying a protective coating can prevent further rusting and enhance the roof’s durability.
Problems at the seams, such as separation or gaps, can lead to water ingress and more extensive damage if not addressed. Ensuring the seams are properly sealed with a coating can prevent leaks and maintain the roof’s resilience. The NFRC highlights properly coated seams can reduce leak incidents by 70%.
2. Water Damage Indicators
Water damage indicators, like persistent leaks and water stains, suggest the need for a waterproof roof coating. Metal roofs can develop leaks around fasteners, seams, or penetrations, leading to significant interior damage if untreated. The NFRC notes 40% of water damage in industrial buildings stems from compromised roofing.
Standing water on the metal roof after rain indicates drainage problems. Ponding can lead to accelerated roof surface deterioration and increased risk of leaks. A waterproof coating can improve drainage and protect the roof. Waterproof coatings can extend the roof's life by up to 25 years, according to the NFRC.
3. Energy Inefficiency Signs
Energy inefficiency signs, such as increased energy bills, indicate a reflective roof coating may be needed. A noticeable rise in energy costs can result from poor roof insulation.
