When most building owners think about flat roof damage, they usually picture storms, aging materials, or standing water. However, one problem that often goes unnoticed is wildlife activity. Birds, squirrels, raccoons, and other animals can cause surprising amounts of damage to commercial EPDM rubber roofs, leading to costly repairs if left unchecked.
At The Flat Roof Guys, we’ve seen firsthand how wildlife can shorten the lifespan of an otherwise healthy flat roof throughout Northeastern Pennsylvania, including Scranton, Wilkes-Barre, Hazleton, Bloomsburg, and surrounding communities.
Birds Can Create Drainage Problems
Birds frequently gather on commercial rooftops because they offer a safe place to rest. Unfortunately, nesting materials, feathers, and debris can clog roof drains, scuppers, and gutters.
When drainage systems become blocked, rainwater has nowhere to go. Water begins ponding on the roof surface, increasing stress on the EPDM membrane and raising the risk of leaks.
Routine roof inspections can identify these issues before they become expensive problems.
Squirrels Love Rooftop Equipment
Squirrels are excellent climbers and often access commercial roofs by using nearby trees or utility lines.
Once on the roof, they may:
- Chew wiring around HVAC equipment
- Damage insulation
- Tear protective coverings
- Build nests around rooftop mechanical units
While they rarely chew through EPDM itself, the damage they cause around rooftop equipment can create entry points for water.
Raccoons Can Be Surprisingly Destructive
Raccoons are strong, curious animals capable of pulling loose flashing, lifting edge metal, and damaging rooftop accessories while searching for food or shelter.
Even small openings around rooftop penetrations can become much larger after repeated wildlife activity.
Wildlife Can Damage Roof Accessories
Many commercial flat roofs contain vents, pipe boots, HVAC curbs, and other penetrations. Animals often investigate these areas because they provide warmth or shelter.
Repeated movement around these components can loosen sealants and create gaps where water eventually enters the building.
Prevention Is Always Less Expensive
The best defense against wildlife damage is regular preventative maintenance.
Professional inspections help identify:
- Loose flashing
- Damaged sealants
- Blocked drains
- Signs of nesting
- Animal entry points
- Roof damage before leaks develop
Removing nearby tree branches and keeping rooftop debris cleaned away also makes commercial roofs less attractive to wildlife.
