How to repair metal roofing
Metal roofs that have been professionally installed have an extremely long lifespan (50+ years). Steel roofs can easily outlast shingle roofs, which is why they’re so popular. However, no roofing material is indestructible, and even metal roofs will require maintenance and repairs from time to time. But can a metal roof be repaired effectively and neatly? Here’s what you need to know about professional metal roof repair.
Common problems with metal roofing:
- oil canning
- corrosion (rust)
- dissimilar metals and materials
- chalking and fading
- scuffing and scratching
- poor installation
Metal Roof Repair is Possible
Depending on the extent of the damage, metal roofs can be repaired. To determine the best repair method, first, identify the source and nature of the damage. While this can be done independently, we recommend hiring a professional roofer like Metal Roofing Sudbury. It could save you hours of annoyance and time. Here’s a look at the different repairs that are possible.
Minor rust spots can be removed by sanding or wiping the affected area with a wire brush. Following the removal of the rust, a primer must be applied, followed by a re-coating layer.
Corroded fasteners are a common problem when dealing with exposed fastener metal roofing. Since the fasteners are exposed to the elements, they degrade quickly and must be replaced every 10-15 years.
When you notice signs of water damage or leaking, corroded or missing fasteners should be replaced to avoid further damage. Fasteners should be replaced and installed with a butyl rubber washer to prevent leaks. Finally, these are to be caulked and sealed with a sealant.
You can do so with simple materials if you only have a few holes to patch. Butyl tape will need to be applied to the perimeter of the hole after cleaning the surrounding area. The hole will then need to be covered with a patch of galvanized metal. The patch will need to be secured with carefully installed screws. A professional roofer should do any patch repair work because this process can quickly go wrong in inexperienced hands. A seam membrane may be the better repair option for certain holes.
Entire Panel Replacement
An entire panel replacement may be required if your metal roofing has sustained extensive damage. Depending on the extent of the damage, the affected metal panels and underlying rafters will need to be identified and replaced.
