Can Pigeons Nest in Roof Overlaps?
Yes.
Some Arizona homes have sections where one roofline overlaps another, creating a protected gap underneath.
Those gaps can become attractive nesting areas for pigeons for the same reason solar panels do. They provide shade, overhead protection, and a place where the birds are harder to disturb.
What Is a Roof Overlap?
A roof overlap is an area where part of the roof extends over another section or structure and leaves an accessible space underneath.
Depending on the home, that opening may be several inches tall and run along a significant section of the roof.
If pigeons can enter it, they may use the cavity for roosting or nesting.
Why Do Pigeons Like These Areas?
Pigeons tend to prefer protected spaces.
An exposed roof ridge may be useful for sitting during the day, but a covered roof opening gives them much more protection.
Once pigeons find a sheltered gap that works, they may return to it repeatedly and eventually build nests inside.
How Can You Tell if Pigeons Are Nesting There?
Watch where the birds disappear.
If pigeons repeatedly land near the same roof section and then walk or fly underneath an overlap, that is a strong sign they are using the space.
You may also notice droppings building up directly below the opening.
Feathers or nesting material around the entrance can be additional signs.
Will Bird Spikes Fix the Problem?
Usually not if the pigeons are actually nesting inside the opening.
Bird spikes are better suited for exposed surfaces where pigeons are landing or sitting.
If the problem is an accessible cavity, physically closing the opening is usually a more direct solution.
The goal is to prevent pigeons from getting into the protected space at all.
What Is Roof Overlap Exclusion?
Roof overlap exclusion involves installing a barrier across the accessible opening while working around the shape of the roof.
The exact method depends on the construction of the home and the size and location of the gap.
It is similar in principle to solar panel pigeon proofing. Instead of trying to scare the pigeons away, you remove access to the nesting area they want to use.
Should Existing Nests Be Removed First?
Yes, accessible nesting material should be addressed before the opening is closed.
If pigeons have been using the area for a long time, there may be nests, droppings, feathers, and other debris inside.
The area should be checked before exclusion so you are not simply sealing over an existing problem.
Can Pigeons Move to Another Part of the Roof?
They can.
If a home has several protected openings, closing only one may cause pigeons to investigate another accessible area.
That is why it is useful to look at the entire property when there is an established pigeon problem.
Solar panels, eaves, rooftop AC units, and roof overlaps can all provide different nesting opportunities.
The Bottom Line
Roof overlaps can create excellent protected nesting areas for pigeons.
If you repeatedly see pigeons disappearing into one of these gaps, the most effective approach is usually to remove accessible nesting material and physically block the opening so they cannot return.
If your pigeon problem involves more than just the solar panels, Cheetah can evaluate additional nesting areas as part of the overall pigeon proofing project.
