Rolled roofing is a cost-effective and practical choice for low-slope roofs. However, over time, seams can become loose due to weather exposure, improper installation, or natural wear and tear. If left unaddressed, these loose seams can lead to leaks and further damage. Here’s a comprehensive guide on how to repair loose seams on rolled roofing.
Step-by-Step Repair Process
- Before starting, wear appropriate safety gear, including gloves and non-slip shoes.
- Use a sturdy ladder and make sure the roof is dry to prevent slips.
- Inspect and locate all loose seams.
- Check for any signs of water damage, mold, or rot underneath the roofing material.
- Use a wire brush to remove debris, dirt, and old adhesive around the loose seam.
- Wipe the area clean with a dry cloth to ensure proper adhesion.
- Carefully lift the loose section using a putty knife.
- If needed, use a utility knife to cut away any damaged or curled roofing material.
- Apply a generous layer of roofing cement under the lifted seam using the putty knife.
- Ensure even coverage to create a strong bond.
- Press the roofing material firmly back into place.
- Use roofing nails to secure the seam, spacing them about 4-6 inches apart.
- Ensure the nails are flush with the roofing material but not overdriven.
- Apply another layer of roofing cement over the seam and nails to seal the repair.
- Smooth it out with the putty knife to prevent water from seeping in.
