Metal Roof Waterproofing 

Metal Roof Leak Repair

To repair a leak in a metal roof, start by identifying the leak’s source. Clean the area thoroughly, removing any debris, rust, or old sealant. For small holes or cracks, a high-quality roofing sealant or caulk compatible with your roof material can be applied. For larger holes, consider patching the area with a piece of matching metal, securing it with screws and sealant. If the damage is extensive, replacing the damaged panels may be necessary. Also, inspect and potentially replace damaged flashing around penetrations like chimneys or vents. 

Here’s a more detailed breakdown of the repair process:

1. Locate the Leak: Thoroughly inspect the roof from both inside and outside to pinpoint the exact location of the leak. Look for water stains, dripping, or any signs of damage on the interior. On the exterior, check for cracks, gaps, loose screws, or deteriorated flashing.

2. Prepare the Area: Clean the affected area meticulously with a wire brush or grinder to remove rust, old sealant, and any debris. Ensure the surface is clean and dry before applying any sealant or patch.

3. Seal Small Holes and Cracks: Apply a high-quality roofing sealant or caulk, ensuring it’s compatible with your roof material. For cracks, apply the sealant in a continuous bead along the crack, ensuring it fills the gap completely. For small holes, you can use a sealant or consider a small metal patch, applying sealant around the edges for a watertight seal. 

4. Patch Larger Holes: Cut a piece of matching metal roofing material slightly larger than the hole. Clean both the patch and the damaged area on the roof. Apply roofing adhesive or sealant to the patch and secure it in place, overlapping the surrounding metal. Ensure the patch is properly sealed around the edges to prevent water intrusion.

5. Address Flashing Issues: Inspect flashing around penetrations like chimneys, vents, or skylights. If flashing is damaged or improperly installed, carefully remove it. Clean the area and install new flashing, securing it with roofing nails and sealant.

6. Replace Damaged Panels: If the damage is extensive and affects multiple panels, consider replacing the damaged sections. Remove the old panels, ensuring proper handling and disposal. Install new panels, aligning them correctly and ensuring a watertight seal at all joints.

7. Tighten or Replace Screws: If loose or missing screws are causing leaks, tighten them or replace them with new ones. Use screws with new rubber washers to ensure a tight, waterproof seal.

8. Consider Professional Help: For complex repairs or extensive damage, it’s best to consult with a professional roofing contractor. They can assess the situation, provide expert advice, and ensure the repair is done correctly and safely.

Metal or steel roof waterproofing is quite different from concrete surfaces, it needs quite different techniques to fix the leakage. In Pakistan mostly metal roof types are corrugated in nature. Due to corrugation not easy to work. Needs extra care & safety for the workers due to the risk of sheet breaking or worker’s falling. These types of roofs has vertical & horizontal joints. These joints are overlapped and fixed with rivets/nuts/bolts.
