How to keep birds from nesting under roof – Birds nesting under your roof can be a nuisance, but there are effective ways to deter them. This comprehensive guide will provide you with detailed information on how to identify nesting sites, implement prevention methods, use humane deterrents, safely remove nests, and implement long-term solutions to keep your roof bird-free.

Identification of Nesting Sites

Birds are attracted to nesting under roofs because these areas provide shelter from the elements, predators, and human disturbance. Common nesting sites include:

  • Eaves: The edges of the roof where it meets the walls of the house provide a sheltered and protected space for birds to build their nests.
  • Soffits: The underside of the roof overhangs, which are often made of wood or vinyl, offer a dry and well-ventilated spot for birds to nest.
  • Chimneys: The warm and sheltered environment inside chimneys is appealing to birds, especially during the cold winter months.
  • Vents: Openings in the roof or walls of the house, such as dryer vents or gable vents, provide access to sheltered spaces that birds can use for nesting.

Signs that birds may be nesting under your roof include:

  • Droppings: Bird droppings, or guano, can accumulate under nesting sites and on the ground below.
  • Feathers: Birds may shed feathers while building their nests or caring for their young.
  • Nesting materials: Straw, twigs, leaves, and other materials may be visible around nesting sites.

2. Prevention Methods

Once you’ve identified potential nesting sites, it’s time to implement prevention measures to deter birds from building nests under your roof. Physical barriers are effective in preventing birds from accessing these sites and can be customized to suit your specific needs.

Netting, How to keep birds from nesting under roof

  • Effectiveness:Netting is a highly effective physical barrier that prevents birds from entering small openings under roofs.
  • Limitations:It can be visually unappealing and may require professional installation.
  • Installation and Maintenance:Secure netting tightly over potential nesting sites using staples or hooks. Inspect and repair any tears or holes regularly.


  • Effectiveness:Mesh is similar to netting but has smaller holes, making it even more effective in preventing birds from entering.
  • Limitations:Mesh can be more expensive than netting and may require custom fabrication for specific areas.
  • Installation and Maintenance:Install mesh over openings using screws or nails. Ensure it is taut and covers all potential nesting spots.


  • Effectiveness:Bird spikes are a humane way to deter birds from landing on surfaces. They create an uncomfortable surface for birds to stand on.
  • Limitations:Spikes may not be effective against all bird species and can be visually unappealing.
  • Installation and Maintenance:Install spikes on ledges, beams, and other surfaces where birds are likely to land. Secure them firmly using screws or adhesive.

3. Humane Deterrents

While it is important to prevent birds from nesting under roofs, it is equally crucial to use humane methods that do not harm them. Here are some effective and compassionate deterrents that can discourage birds from nesting in these areas:

Visual Deterrents

  • Reflective Tape:Birds are wary of shiny and reflective surfaces. Placing reflective tape around potential nesting sites can create a visual barrier that deters them from approaching.
  • Owl Decoys:Owls are natural predators of birds, and their presence can be an effective deterrent. Placing realistic owl decoys near potential nesting areas can scare birds away.
  • Bird Silhouettes:Birds are territorial and avoid areas where they perceive other birds to be present. Placing bird silhouettes on roofs or nearby trees can create the illusion of an occupied territory, discouraging other birds from nesting there.

Auditory Deterrents

  • Ultrasonic Devices:These devices emit high-frequency sounds that are inaudible to humans but can be irritating to birds. Ultrasonic devices can be placed near potential nesting sites to deter birds from approaching.
  • Motion-Activated Sprinklers:These devices detect motion and release a spray of water when birds approach. The sudden burst of water can startle birds and discourage them from nesting in the area.

4. Nest Removal and Cleaning

Removing active nests from under roofs requires caution to avoid disturbing birds or damaging the roof. It’s crucial to wear protective gear like gloves and a mask to prevent contact with nesting materials that may carry diseases.

Proper Removal Techniques

  • Wait until the nesting season is over and the chicks have fledged before removing the nest.
  • Use a ladder to reach the nest and carefully remove it using a trowel or dustpan.
  • Avoid touching the nest or chicks directly. If necessary, use gloves or a towel to handle them.
  • Dispose of the nest in a sealed bag in the trash to prevent disease transmission.

Cleaning and Disinfection

After removing the nest, thoroughly clean the area with a disinfectant solution to prevent disease transmission. Use a stiff brush or broom to remove any remaining nesting materials.

  • Apply a disinfectant solution (e.g., bleach diluted in water) to the area and let it sit for several minutes.
  • Rinse the area thoroughly with water and allow it to dry completely before repairing any damage to the roof.

5. Long-Term Solutions: How To Keep Birds From Nesting Under Roof

Once you’ve addressed immediate nesting issues, it’s crucial to implement long-term strategies to prevent future nesting attempts. These solutions focus on modifying the structure of your roof to make it less appealing to birds and incorporating architectural features that deter them from nesting.

Structural Modifications

Carefully inspect your roof for any gaps or damaged areas that could provide entry points for birds. Seal these openings using appropriate materials like caulk or expanding foam. Additionally, consider replacing any worn or damaged roofing materials to eliminate potential nesting spots.

Bird-Resistant Building Materials

When choosing roofing materials, opt for those that are less attractive to nesting birds. Metal roofing, for instance, is smooth and slippery, making it difficult for birds to grip and build nests. Other options include vinyl siding, which is not easily penetrable, and concrete tiles, which are heavy and provide minimal shelter.

Architectural Features

Incorporate architectural features into your roof design that discourage nesting. Installing bird screens over vents and chimneys prevents birds from entering these areas. Bird spikes, which are thin, pointed rods, can be placed along rooflines and other potential nesting spots to deter birds from landing and nesting.

Regular Maintenance

Regularly inspect and clean your roof to remove any nesting materials or debris that could attract birds. Trim overhanging branches that provide access to your roof, and keep gutters clean to prevent water accumulation that could create a moist environment suitable for nesting.
