Don’t wait for the first leak call. Get ahead with a fast roof check.

<<Before Puget Sound's rainy season, property managers should clear and test drainage, inspect seams, flashings, penetrations, rooftop units, edges, and traffic areas, review leak history, confirm roof access, and assign repair priorities with photos and follow-up dates.>>
Rain exposes conditions that dry-weather inspections may not reproduce, but waiting for interior water is an expensive way to find a blocked drain or open flashing. A seasonal review should focus on the routes water takes and the details most likely to interrupt building operations.
The checklist does not promise a leak-free season. It gives the property team a documented baseline, a list of correctable conditions, and a faster way to respond if water appears.

Remove leaves, sediment, branches, construction debris, and vegetation from drains, scuppers, gutters, downspouts, and flow paths. Confirm strainers and covers are secure and that discharge points are not blocked.
Look for dirt lines, displaced ballast, staining, algae, or surface deposits that show where water has been holding. Chronic low areas may need design review rather than another cleaning visit.
Seams, wall flashings, curbs, pipes, drains, edge metal, transitions, and previous repairs should be checked for openings, movement, loose components, or deteriorated sealant. Rooftop units deserve attention because service work and vibration can affect nearby details.
Review access routes and walk pads for punctures, compression, dropped fasteners, sharp debris, and damage from equipment contractors. Record new rooftop work so responsibility and follow-up do not disappear between vendors.

Collect the date, weather, room, ceiling location, photos, and previous repair for each known leak. Water may travel inside the assembly, so the map should guide investigation rather than assume the defect is directly above the stain.
For multi-tenant or multi-building properties, standardize how occupants report water. A complete record is more useful than separate emails that never reach the roof file.
Confirm safe roof access, keys, ladders, escorts, tenant contacts, interior protection supplies, and the person authorized to approve emergency containment. Keep roof plans, warranties, reports, and recent repair photos in one accessible location.
Prioritize known open conditions before cosmetic items. If work cannot be completed immediately, document temporary limitations and the permanent follow-up required.
Timing | Property manager action | Record to keep |
|---|---|---|
Before rainy season | Clean drainage, inspect details, repair priority defects, and confirm access | Dated photos, roof map, open-item list, and responsible person |
During a leak | Protect interiors, record conditions, avoid unsafe roof access, and request diagnosis | Time, weather, room, photos, affected operations, and containment actions |
After the event | Verify permanent scope, inspect related areas, and update the roof history | Repair photos, findings, limitations, invoice, and next inspection date |
Flat Roof Pros connects roof condition, drainage, leak history, and building operations in one seasonal plan. Findings are documented so the property manager can authorize immediate corrections, schedule planned work, and monitor lower-priority conditions.
How often should roof drains be checked during fall?
The interval depends on nearby trees, debris load, roof design, and weather. High-debris roofs may need checks more often than a fixed annual visit.
Can maintenance prevent every rainy-season leak?
No. Maintenance reduces known risks and helps detect change, but severe weather, hidden conditions, new damage, and building-system problems can still cause water entry.
Should a property manager walk the roof during a storm?
Only when access is authorized and conditions are safe. Interior protection and documentation may be the appropriate first action when the roof is wet, windy, dark, or otherwise hazardous.
What should be included in a seasonal roof report?
Include roof areas, drainage, defects, photos, priority, recommended action, completed work, open limitations, and the date for follow-up.
Flat Roof Pros can inspect commercial and multi-family roofs, clear maintenance priorities, and organize findings for property management follow-through.
