Summer might seem like the season when your flat roof gets a break—but in reality, it’s one of the most important times for inspections and maintenance. Heat, UV exposure, and sudden summer storms can all take a toll on your roofing system.
For commercial property owners and facility managers, following a seasonal checklist helps extend roof life, reduce costly repairs, and ensure your building is ready for the months ahead.Here’s our summer flat roof maintenance checklist to keep your investment in top shape.
1. Inspect for Heat & UV Damage
Why it matters: Extended exposure to high temperatures and direct sunlight can cause membranes to crack, blister, or shrink—especially on older systems. Key steps to address this:- Have a qualified roofing professional assess for visible cracks, bubbles, or discoloration.
- Pay extra attention to south- and west-facing areas where sun exposure is strongest.
- Complete repairs promptly to prevent further deterioration.
2. Check for Ponding Water After Storms
Why it matters: Even in summer, heavy downpours can create pooling water, which accelerates wear and may indicate drainage issues. Key steps to address this:- Arrange post-storm inspections to identify areas where water lingers.
- Ensure drains and scuppers are clear to restore proper flow.
- Consider adding tapered insulation in low spots if ponding is recurring.
3. Examine Flashing & Seals
Why it matters: Flashing protects roof edges, penetrations, and transition points. Summer heat can cause sealant to dry out and crack. Key steps to address this:- Have all flashing inspected for gaps, lifting, or brittle sealant.
- Reseal or replace damaged sections before leaks occur.
- Confirm any work aligns with manufacturer specifications to maintain warranties.
4. Clear Drains, Gutters & Scuppers
Why it matters: Leaves, twigs, and debris can block drainage systems, leading to ponding or overflow damage during summer storms. Key steps to address this:- Remove debris from drainage systems to ensure free water flow.
- Install strainers or guards to help reduce clogs.
- Incorporate drain cleaning into routine maintenance.
5. Look for Signs of Foot Traffic Damage
Why it matters: HVAC servicing and other rooftop work often happen in summer—putting added stress on the membrane. Key steps to address this:- Inspect for punctures, scuffs, or torn seams in areas where work has been performed.
- Install walkway pads in high-traffic zones.
- Reinforce roof protection protocols with any contractors working on-site.
6. Schedule a Professional Roof Inspection
Why it matters: A professional can spot issues you might miss, use infrared scans to detect hidden moisture, and recommend cost-effective repairs. Key steps to address this:- Schedule at least one professional inspection during summer.
- Request a detailed report with photos for documentation.
- Use findings to plan preventative maintenance before fall.
