Commercial Roof Maintenance for Flat Roofs

Flat roofs are commonly used in commercial buildings due to their cost-effectiveness and easy accessibility. These roofs are typically made from materials like Thermoplastic Olefin (TPO), Ethylene Propylene Diene Monomer (EPDM), and Polyvinyl Chloride (PVC), offering durability and weather resistance. However, they can experience issues such as water pooling, membrane punctures, and UV damage, necessitating regular maintenance. Effective flat roof maintenance involves regular inspections to identify and address potential issues early, ensuring the roof remains functional and extends its lifespan.

How Many Inspections Should I Get Per Year?

What Needs to Be Inspected?

Regular inspections are crucial for maintaining the integrity of flat roofs. It is recommended to conduct inspections at least twice a year, typically in the spring and fall. These seasonal inspections help identify and address damage caused by extreme weather conditions. Additionally, more frequent inspections may be necessary if the roof has a history of issues or if severe weather events occur.

During a flat roof inspection, focus on key areas prone to damage. Inspect the drainage systems to ensure there are no blockages that could cause water pooling. Check seams and flashing for signs of wear and separation. It is also important to look for cracks, blisters, and membrane integrity. Roof penetrations such as vents and HVAC units should be inspected for leaks and wear. See the commercial roof maintenance checklist for flat roofs below for a full list.
