Is Your Home Ready For Winter? 3 Steps To Winterize Your Roof

With winter just around the corner, it's time to get your asphalt shingles prepared for the colder weather. Rain and snow can wreak havoc on your roof. Pests can wreak havoc as well, especially mice and squirrels. To protect your home and your family this winter, you should weatherize your roof before the cold weather arrives. Here are some precautionary steps you can take to prevent damage to your roof during the cold weather.

Repair Damaged Shingles

When it comes to weatherizing your roof, the first thing you should do is repair the damaged shingles. Sun exposure can cause the edges of your shingles to cup and curl. When that happens, moisture can build up under the shingles, which can lead to roof and shingle rot. The curling can leave your shingles exposed to wind damage.

To repair cupped or curled shingles, lift up the edge and apply a generous amount of roofing cement to the area below. Press the shingle down to secure the cement. Next, place several roofing nails along the edge of the shingle, Repeat this process on all of your curled or cupped shingles. You can use the same process to secure loose shingles as well.

Remove Dirt and Debris

Once you've repaired your damaged shingles, you'll need to give your roof a thorough cleaning. Washing your shingles will remove the dirt and debris that can lead to premature aging of your shingles.

Supplies You'll Need

  • Slip-resistant shoes
  • Garden sprayer
  • Water
  • Grease-cutting detergent
  • Household bleach
  • Push broom
  • Garden hose


  1. Fill your garden sprayer with water.
  2. Add ¼ cup of detergent and 1-cup of bleach to the water.
  3. Put your slip-resistant shoes on to prevent slipping in the water.
  4. Using your garden sprayer, apply the bleach solution to the lower edge of the roof.
  5. Starting at the bottom will allow you to work your way up towards the top of the roof.
  6. Scrub the area with your broom, and then move on to the next section.
  7. Continue moving along the edge of your roof and then up until the entire roof has been scrubbed.
  8. Using your garden hose, rinse the roof with fresh water.

Trim the Trees

If you have trees growing near your home, low-hanging branches can create the perfect access point for mice and other rodents. Once they're on your roof, they can chew through the shingles in an attempt to gain access to your home. To protect your roof, be sure to trim all of the low-hanging branches so they no longer rest on your roof.

The cold weather will soon be here. Now's the time to get your roof ready for those harsh winter months. Use the tips provided here to protect your roof this winter. If you notice severe damage during your maintenance, be sure to contact a roofing contractor
