Prevent Gulls From Nesting On Your Rooftops This Spring

Feb 20, 2025

While gulls can be a nuisance in any season, nesting season, which begins in March and April is when gulls are most territorial and aggressive to other gulls and humans alike! Biologically, gulls will return to where they were born or previously nested to lay eggs, so if your property has experienced gull issues in the past, you may be at risk of returning nesters this Spring. However, proper management of gulls and gull egg removal is not a simple process, and requires permits and approvals by multiple regulators, including the United States Department of Agriculture (USDA), the United States Fish & Wildlife Service, and in some instances, State regulators. Gulls are protected under the Federal Migratory Bird Treaty Act, and as such, you may find yourself hosting hundreds of unruly and destructive “guests” this May, if you don’t take action now to secure permits.  

As it’s February, there’s still time to take action. Here are 4 signs your rooftop is vulnerable to nesting gulls. If you identify with these signs, contact us, before it’s too late. 

4 Signs Your Rooftop Is Vulnerable To Nesting Gulls

Before selecting a site to nest, gulls will scout different locations. There are telltale signs to their behavior that might alert you in advance of their intentions to nest on your property:

  1. Loafing: If you see gulls repeatedly spending time on your property, chances are they’re scoping your building as a potential site to nest. 
  2. Increased Droppings: When you begin to see more than the usual amount of gull waste on your rooftop or around the building, it’s time to take action. Gull droppings are acidic and can harm rooftops and equipment: bacteria from gull waste can get into HVAC systems and create a health risk inside the building. Accumulation of fecal matter can also clog roof runoff drains and cause general damage to the roof itself. 
  3. Increasing volume of gull sounds: Gulls are social creatures. Colonies range between 30-1000 birds and become deafening when disturbed. If your rooftop has been selected as a nesting ground for gulls, chances are, you are at risk of dozens, if not hundreds of gulls. 
  4. Rooftop debris: The appearance of debris like twigs, rocks or pebbles on your roof is a good sign that gulls may be taking an interest in your rooftop. 

When to Call an Expert

Managing gulls on your own in nesting season is not recommended – from a safety, effectiveness, and legal perspective. In addition to navigating the complexities of multi-agency permitting requirements, the most effective management of gull conflicts is built around a deep knowledge of bird biology and behavior.
