Pigeons nest on roofs because they find shelter, safety from predators, and often food nearby
Pigeons roost on roofs for the same reason they choose ledges, bridges, and other high structures: protection and a vantage point. Once a few birds settle in, they leave droppings that attract more pigeons, and the problem compounds. Pigeon waste is acidic and can damage roofing materials, clog gutters, and create slip hazards. The birds also carry parasites and can introduce disease to areas where people live and work.
Removing pigeons requires a two-step approach: making your roof inhospitable to them right now, and preventing new birds from landing later. Neither step works alone. Scaring away the current flock without blocking future access means they will return within days. Blocking access without removing the birds already there leaves them trapped and stressed, which can make the problem worse before it improves.
Key Takeaways
- Pigeons return to roofs where they have nested before, so removing the current flock is only half the solution.
- Physical barriers like netting, spikes, and wire are the most reliable long-term deterrents; sound and visual scares work temporarily but lose effectiveness within weeks.
- Cleaning droppings and removing food sources (open trash, pet food, fallen seed) makes your roof less attractive to new birds.
- Professional removal is worth the cost if the infestation is large, if you are uncomfortable working at height, or if pigeons have nested inside your attic or soffit.
Remove the birds already on your roof
Start by identifying where the pigeons are actually roosting. Check your roof edges, gutters, vents, and any recessed areas where they gather. Look for droppings, feathers, and nesting material as signs of regular use.
For a small number of birds, a combination of noise and visual deterrents can work in the short term. Reflective tape, pinwheels, or predator decoys (plastic owls or hawks) startle some pigeons, but they learn quickly that these are not real threats. Ultrasonic devices and noise makers have mixed results; pigeons habituate to them within two to four weeks. If you use these methods, move them every few days to prevent the birds from recognizing the pattern.
If the flock is large or these methods do not work, you may need to contact a licensed pest control or wildlife removal service. They can use live traps, netting, or one-way doors to remove birds humanely. Many jurisdictions have rules about how pigeons must be handled, so check local regulations before attempting removal yourself. Some areas require that trapped birds be released, while others allow euthanasia only under specific conditions.
Install physical barriers to prevent landing and nesting
Roof spikes are the most common and cost-effective barrier. They are thin metal or plastic strips with pointed projections that make landing uncomfortable without harming the birds. Install them along roof edges, ledges, gutters, and any flat surface where pigeons perch. Spikes work best on narrow surfaces; they are less effective on wide, flat roofs where birds can land between rows. Expect to pay $1 to $3 per linear foot for materials and installation, though prices vary by region and roof complexity.
Netting physically blocks pigeons from entering an area. It is the best choice if birds are nesting under eaves, in soffits, or around vents. Install netting at least 3 inches away from the surface so pigeons cannot peck through or reach behind it. Netting requires careful installation to avoid gaps and must be checked regularly for damage. It is more expensive than spikes—typically $5 to $15 per linear foot—but it is also more durable and works on any roof shape.
Bird wire (also called tension wire or electric track) is a thin, nearly invisible cable strung across roosting areas. When a pigeon lands, the wire moves under its feet, creating an unstable surface that discourages perching. It works well on ledges and edges but is less effective on flat surfaces. Installation usually requires professional help, and the system must be maintained to keep wires tight and functional.
Slope modifications are a permanent solution for flat or low-slope roofs. Installing angled surfaces or covers over flat areas makes it difficult for pigeons to land and nest. This is expensive and usually only done during a roof replacement or major renovation, but it eliminates the problem for decades.
Clean droppings and remove food sources
Pigeon droppings attract more pigeons and damage roofing materials. Clean the roof thoroughly after you have removed the birds or installed barriers. Use a pressure washer on a low setting to avoid driving water under shingles or damaging flashing. Wear a respirator mask when cleaning, as dried pigeon droppings can carry disease-causing organisms.
Pigeons stay in areas where food is available. Remove or find anything that feeds them: open garbage cans, pet food left outside, bird feeders, or spilled seed from landscaping. If you have a garden, use netting to protect plants. Clean up fallen fruit and nuts from trees near your roof. These steps alone will not drive away an established flock, but they prevent new birds from settling in once you have removed the current ones.
Seal entry points to your attic and walls
Pigeons can squeeze through gaps as small as 1 inch and will nest inside your attic, soffit, or walls if given the chance. After removing birds from your roof, inspect the entire perimeter for openings. Check around vents, where siding meets the roof, gaps in flashing, and damaged soffit boards.
Seal gaps with hardware cloth (a metal mesh), caulk, or foam sealant. For larger openings, install one-way doors that allow birds already inside to leave but prevent them from re-entering. Leave one-way doors in place for at least two weeks to may support all birds have exited, then seal the opening permanently. If you find an active nest inside, do not seal it when ready; wait until the young have fledged or contact a wildlife removal service for guidance.
Understand why sound and visual scares have limited success
Reflective objects, predator decoys, and noise makers work initially because they startle pigeons. However, pigeons are intelligent birds that learn quickly. Within a few weeks, they realize that the owl decoy never moves, the reflective tape does not hurt them, and the noise does not signal real danger. Once they habituate, these deterrents become background clutter.
If you choose to use these methods, change them frequently and move them every few days. Combine multiple types of deterrents so pigeons cannot predict the pattern. Understand that these are temporary measures meant to buy time while you install permanent barriers or arrange professional removal. They should not be your only strategy.
When to hire a professional
Professional wildlife removal or pest control services are worth the cost in several situations. If you have a large flock, if the infestation is in a location you cannot safely access, or if pigeons have nested inside your attic or walls, a professional can handle the job more efficiently and safely than you can alone.
Get quotes from at least two licensed services in your area. Ask what methods they use, whether they remove birds humanely, and what warranty they offer on barriers or exclusion work. Some services may provide that pigeons will not return for a set period; others do not. Understand what is included in the price—removal, cleanup, barrier installation, and follow-up visits all cost extra at some companies.
Frequently Asked Questions
Is it legal to trap and relocate pigeons?
Laws vary by location. Some areas allow relocation, while others require that trapped pigeons be euthanized or released on the property where they were caught. Check with your local animal control or wildlife agency before trapping. Many pest control services know the local rules and will handle this for you.
How long do roof spikes last?
Metal spikes typically last 10 to 15 years or longer, depending on weather and maintenance. Plastic spikes may degrade faster in direct sunlight, usually lasting 5 to 10 years. Check them annually for damage or loose sections, and replace any that are bent or missing.
Can I use poison to kill pigeons on my roof?
Poison is not recommended. It is inhumane, often illegal in residential areas, and can harm other wildlife or pets that eat poisoned birds or contaminated food. Barriers and removal are more effective and do not create secondary hazards.
Will pigeons come back after I remove them?
Yes, if you do not install barriers. Pigeons have strong site fidelity and will return to roofs where they have nested before. This is why removal alone does not solve the problem—you must make the roof physically inaccessible to prevent new birds from landing.
How much does professional pigeon removal cost?
Costs vary widely by region, the size of the infestation, and what work is included. Removal alone may cost $300 to $800. Adding barrier installation (spikes, netting, or exclusion work) typically runs $1,000 to $3,000 or more. Get a detailed estimate before hiring.
