Roofing is a vulnerable place on the exterior of your house because there are several places where pests can enter, and the hole they find or create may only be visible from your yard if it is severe. Features that break up the straight line of a roof, though visually appealing, are spots where shingles and tiles are the most susceptible to damage because they are difficult to completely seal. Any slight gap in the shingles or flashing at these junctures is enough to make animals decide to move in.
Roof Edges and Eves
Thawing and freezing cycles during winter months soften the wood that covers the edges and eves of your roof. When a rodent finds soft wood, it can easily chew through to create a small entrance. Raccoons and bats commonly chew or rip through soffit as well.
Vents
Vents are a necessary part of a good roofing system because they release the hot air that would otherwise be trapped in your attic. Unfortunately, this release of air is an invitation to animals that can chew through the vent covers.
Chimney Entrances
An uncapped chimney can become an entrance for birds, bats and rodents. Animals are known to build nests inside chimneys, causing a serious hazard the next time a fire is lit.
Wall Entrances
Walls make up such a large percentage of the exterior of your home that there are a lot of opportunities for small gaps of damage to occur. In addition to damaged areas, your walls are vulnerable where vents and plumbing outlets are placed. Rodents are good at chewing through vents and the rubber material that seals plumbing outlets, and the holes they create are small enough that they are not easily visible.
Porch or Deck Entrances
Many wild animals love the dark space under a porch or deck where it stays warm during winter months and cool in the summer. This space attracts rodents, bats and larger animals such as raccoons and skunks. Pests are known to chew or dig their way under a porch or deck.
