In Ottawa, where roofing faces severe weather conditions, maintaining the valleys of your roof is crucial. This guide provides a step-by-step approach to repairing roof valleys, ensuring your home remains safe and dry.

Understanding Roof Valleys

Roof valleys are the V-shaped metal channels that run up and down the ‘folds’ where two roof slopes meet. They are critical in directing water and snow away from the roof to prevent leaks and water damage.

Signs of Roof Valley Damage

Before you begin the repair, identify signs of damage which might include:

• Water stains on the ceiling beneath the valleys
• Visible rust or holes in metal valleys
• Cracks or breaks in the shingles around the valley area

Materials Needed for Roof Valley Repair

To repair a roof valley, you’ll need the following materials:

• Replacement shingles (if necessary)
• Metal flashing or valley material
• Roofing cement
• Nails and hammer
• Utility knife

Steps to Repair a Roof Valley

1. Remove Damaged Material: Carefully remove any damaged shingles or flashing from the valley.
2. Clean the Area: Ensure that the valley is free from debris, dust, and old roofing cement.
3. Apply New Flashing: Install new metal flashing, ensuring it is securely fastened and overlaps adequately for water runoff.
4. Replace Shingles: If necessary, replace the shingles around the valley, making sure they are well integrated with the flashing.
5. Seal the Valley: Apply roofing cement to seal and waterproof the new materials.

Maintenance Tips for Ottawa Roofing

Maintaining your roof’s valleys can extend the life of your roof. Regular checks, especially after heavy storms, can prevent major repairs. Ensure that the valleys remain clear of debris to facilitate proper water flow.
