More than an aesthetic issue, the gaps between a roof and a wall can create serious problems like water damage, pest infiltration, or energy loss. The solution to these problems must give a house its structural integrity. Follow these easy steps to effectively seal the gap between your roof and wall.
Step 1: Thorough Inspection
First of all, any repair should start with an inspection. The full extent of the gap and any other issues must first be understood.
- Measure the Gap: Measure the width and length of the gap using a tape measure to guide the choice of materials.
- Check for Damage: Check the gap for water damage, mold, or pest activity. If so, fix these issues before sealing the gap.
- Cleaning the Area: Clear the gap of dust, dirt, or other loose materials. A clean surface is essential for the sealant to adhere well.
Step 2: Select the Right Materials
The second step in how to seal the gap between the roof and the gutter is selecting the right materials. They include:
- Caulk or Sealant: For the smaller holes, an exterior-grade caulk or sealant will suffice. It needs to be weather-resistant to hold up outdoors.
- Backer Rod: Fill some parts of the bigger gaps with a backer rod. This provides a good base for the sealant and avoids its sinking.
- Caulking Gun: A caulking gun dispenses the sealant uniformly and as needed.
Step 3: Close the Gap
With those materials, proceed with the following steps to seal up the gap:
- Backer Rod Insertion: In case the gap is larger than 1/4″, a backer rod should be inserted first. Push the rod into the gap, ensuring it is just below the surface.
- Apply Caulk: Cut the caulk tube tip at an angle. Load the tube into the caulking gun and then run a continuous bead of caulk along the gap with a steady hand to ensure even application.
- Smooth the Caulk: Smooth the bead with a caulk-smoothing tool or a wet finger. This will ensure better bonding and also look better aesthetically.
