Spring 2026 is predicted to bring a higher-than-average risk of severe thunderstorms, with warmer Gulf of Mexico temperatures fueling storm development across the Southeast and Midwest, according to Capital City Roofing's spring forecast.
For multi-site operators, the risk is not just roof damage. It is the discovery, after a storm, that you cannot file an insurance claim because you do not have the documentation the carrier requires.
The Documentation Gap
Most commercial roof warranties require at least one documented annual inspection by an authorized contractor to remain valid. An increasing number of commercial insurance carriers now require biannual inspection records as a condition of storm damage claim payment, according to Nations Roof's quarterly outlook.
For a 200-location portfolio, that means 400 documented inspections per year. Most operators are not close to that number.
What Inspectors Look For
Blocked or undersized drainage systems top the list. Standing water accelerates membrane deterioration and increases structural load, according to commercial roof inspection guidelines. Other critical items:
- Membrane condition (blistering, cracking, ponding)
- Flashing integrity at penetrations and edges
- Gutter and downspout flow
- HVAC unit curb seals (a major leak source)
- Previous repair quality
The Multi-Tenant Complication
Shared roofing systems in multi-tenant retail centers create coordination challenges between tenants and landlords, according to WaterTight Roofing analysis. Water intrusion in one unit can affect neighboring businesses, creating liability exposure that a single inspection cannot resolve.
What to Do Before Storm Season
- Schedule inspections for every location before May. Document everything with photos, timestamps, and inspector credentials.
- Check your insurance policy language. Know exactly what documentation is required for storm damage claims.
- Verify warranty compliance. Pull your roof warranty files and confirm inspection frequency requirements.
- Prioritize drainage. Blocked drains are the number one cause of preventable roof damage, and the cheapest to fix.
- Budget for it. Proactive roof maintenance cuts total lifecycle costs by up to 50%, per industry studies.
