How to repair or replace a ridge cap on your roof

Your roof is one of the most crucial components of your home, protecting you and your possessions from the elements. The ridge cap, the peak of your roof, is especially important because it provides an extra layer of protection against water infiltration and serves as a finishing touch to your roof’s aesthetics.

Over time, ridge caps may deteriorate due to weather exposure or general wear and tear. When this happens, it’s essential to replace or repair them to maintain the integrity of your roof. So let’s take a look at the process of replacing and repairing a ridge cap on your roof.

Tools and Materials You’ll Need

Before you begin, gather the necessary tools and materials:

1. Safety gear: Safety goggles, gloves, and a harness if your roof has a steep pitch.
2. Ladder: Ensure it’s stable and securely positioned.
3. Roofing materials: Ridge cap, roofing cement, and nails.
4. Pry bar or roofing shovel.
5. Hammer or roofing nail gun.
6. Utility knife.
7. Caulking gun and roofing caulk.
8. Measuring tape.
9. Chalk line.
10. Roofing cement applicator or putty knife.

Step 1: Safety First

Always prioritise safety. Inspect your ladder, wear appropriate protective gear, and ensure you have a spotter or helper nearby. If your roof has a steep pitch or is too high, consider hiring a professional roofer.

Step 2: Remove the Old Ridge Cap

Start by using the pry bar or roofing shovel to carefully lift the old ridge cap shingles. Work systematically, removing nails as you go. Be cautious not to damage the underlying roof shingles.

Step 3: Clean the Area

Once the old ridge cap is removed, clean the area thoroughly. Remove any remaining debris, nails, or old roofing cement. A clean surface is essential for proper adhesion of the new ridge cap.

Step 4: Measure and Cut the New Ridge Cap

Measure the length of your ridge and cut the new ridge cap accordingly if required. Use a chalk line to mark straight lines for precise cuts. Ensure that the new shingles are long enough to overlap the underlying roof shingles.

Step 5: Apply Roofing Cement

Apply a generous layer of roofing cement along the ridge. This will help seal the ridge cap and provide additional waterproofing.

Step 6: Install the New Ridge Cap

Carefully place the cut ridge cap onto the cement, ensuring they overlap each other and the underlying roof material. Nail them in place using a hammer or roofing nail gun. Use roofing cement to seal the edges and ends of each cap for added security.

Step 7: Secure the Ridge Cap

To ensure the ridge cap is firmly attached, use roofing nails or screws to secure it to the roof decking. Make sure it’s aligned with the ridge and evenly spaced.

Step 8: Seal the Joints

Using a caulking gun, apply roofing caulk along the joints and seams of the ridge cap. This will provide an extra layer of protection against water infiltration.

Step 9: Inspect and Clean Up

Carefully inspect your work to ensure the ridge cap is securely in place and all seams are sealed. Remove any excess roofing cement or caulk. Dispose of old materials and debris properly.

Replacing or repairing a ridge cap on your roof is a manageable DIY project if you have the necessary tools, materials, and safety precautions in place. However, if you’re uncomfortable working at heights or dealing with roofing materials, it’s always wise to consult with a professional roofer. Properly maintained ridge caps are essential for a leak-free and long-lasting roof, so take the time to ensure your roof’s peak is in good condition.
