Industrial roofs offer seagulls vast expanses of open roof on which they can nest and raise there young in absolute safety at height away from predators. Most industrial roofs have protrusions such as vents and skylights, behind which the gulls can build a substantial nest.
Which species can cause problems?
Seagulls (herring Gulls & Black-Backed Gulls)
What are the problems?
Gulls can pull away roofing materials such as insulation to form nests causing damage
Nest materials, food debris and feathers can block the roof’s drainage systems causing leaks and floods
Old nests deteriorate into a peat-like substance from which vegetation can grow, damaging roof sheets and blocking gutters
Gulls can peck holes in fragile roof lights whilst opening shell fish by hammering them with their beaks on the roof’s surface
The roof will be aggressively defended against human access during the nesting season causing access problems.
Lice, ticks, mites and maggots associated with the infestation can find their way inside the building affecting the occupiers.
How can I stop the problem?
On large surface area roofs there are four main solutions depending upon the severity of the infestation:
Use Bio-Acoustics for light pressure infestations where the birds are perching only without a food source nearby
For medium pressure infestations where the birds are either perching or roosting use a Live Predatory Response (Falconry)
Use Netting for heavy pressure infestations where the birds are nesting and/or there is a food source present
Managing Out The Pest is an annual nest removal programme which can also combat this problem.
