How To Keep Pests Off Your Roof And Out Of Your Attic | Pacific West Roofing

All kinds of critters and creatures can get to your roof and make it, or your attic, their home. Not only is their scratching and scampering around annoying, but their invasion into the structure of your home can cause damage and more inconveniences. We’ve heard all kinds of stories about birds, squirrels, raccoons, bats, bees and ants, and many homeowners want to know how to keep these pests away from their home. So, we’ll give you some advice on how to keep pests out of your attic and off your roof.


First things first, if you have pests that are getting into your attic, you’re going to need to find their access point(s). When inspecting your roof and the exterior of your home, pay particular attention to dormers, damaged flashings and the areas where the siding meets the soffits. If you find any evidence of your little friends, such as holes, claw marks, chew marks or nests, this will be your major point of interest.


Next you’ll need to check inside your attic, patch up the holes and reinforce areas that might be susceptible to pest entry. Before you go up there though, consider the possibility that whatever you’re dealing with might currently be up there and may not take kindly to you disturbing them. You might think about setting a trap or two or hiring the help of a pest control company so you can be sure the coast is clear.


Once you get up there, cover any vents to the outdoors with a heavy gauge wire screen and make sure you attach it adequately. Squirrels can shimmy through if you only attach a screen at the corners. Patch any holes that the critter used to get in with a non-chewable material. If you choose to use wood to cover the whole, make sure it is decently thick as squirrels have been known to chew through two inches of wood. Reinforce any other area in your attic where there are only two inches between you and the outdoors with additional pieces of wood or wire screens. Then, clean up any droppings that have been left by the pests, which can be like a glowing review of your attic’s hospitality.


When you are sure your attic is secure, make any necessary provisions to be sure pests can’t reach your roof. One of the easiest ways for them to get to your roof is from the trees. If you have any branches extending onto or within inches of your roof, cut them back so that there are at least six feet of clearance. Remember, squirrels can jump so a few feet might not be enough. Also be aware of power lines touching your roof. We once saw an army of carpenter ants crawling along a line and onto a customer’s roof, causing all kinds of problems.

How To Install A Bathroom Vent Through The Roof | Pacific West Roofing

If you are tired of that steamy bathroom after your shower, or have “install bathroom vent” on your DIY list for your home, we’ve got some tips that will help you do it correctly and avoid some common mistakes that could cost you big in the long run.

install bathroom vent through the roofIf you’re thinking that you can use an existing vent, or even just vent into the attic, you’ll want to stop right there! If you plan to tap into an existing vent pipe, you could block the venting of the original source and create big problems at that location. Now, if you’re thinking about venting into the attic, you’ve got some problems just around the corner. You will be venting warm, humid air into your attic which is not a good idea, as it raises the temperature of your attic. As well, venting that warm, humid air into your attic in the winter causes even more humidity and moisture to collect in the attic, leading to possible damage to your attic, walls, and potentially worse.

Now that we are on the same page with “What Not To Do,” let’s get that vent installed!

  1. Figure out where you will install the vent
    • Pick the spot in your bathroom where you want to install the vent.
    • In the attic, make sure there are no obstructions for the vent pipe from the bathroom ceiling to the roof (make sure you have a truss or stud to mount the vent to in the bathroom from overhead).
    • It’s a good ideA to drill a hole from the attic into the bathroom ceiling to mark your installation location.
  2. Mount the vent into the ceiling
    • Cut the hole overhead in the ceiling (following the manufacturer’s instructions).
    • Install the vent into the ceiling.
  3. Attaching the vent pipe
    • In the attic, attach the vent pipe from the vent up to the roof.
    • Mark the roof where you will cut the opening for the vent pipe and roof hood.
    • Drill a hole in the center of your mark, and leave the drill bit in the hole so you can find it outside on the roof.
  4. Installing the vent hood
    • Using a jig saw, cut a 4” round hole using the center point of the hole from your drill.
    • Measure out a square around the 4” hole slightly larger than the vent pipe.
    • Use a “hook blade” to cut away the asphalt shingles around the 4” hole.
    • Pry up the shingles around the square gently.
    • Using asphalt roof cement, apply a bead around the bottom of the vent.
    • Slide the vent under the shingles, so they cover the vent flange.
    • Nail the corners of the flange, and cover the nail heads with roofing tar.
  5. Install the vent pipe
    • In the attic, install the vent pipe to the vent hood from the underneath.
