Unique Considerations With Metal Roofs
Repairs to a metal roof can be complicated.
The following is a recommended process for repairing a hole in ametal roof system.
Safety Considerations
Safety is a significant concern when completing any roof-repair project.
Wipe away any cleaner residue with a wet cloth.
Scuff the Metal
Use awire brushto scuff the surface where the repair will be made.
Scuffing will help the sealant bond to the metal.
Apply a little more sealant here to eliminate any gaps.
Secure the Patch
Secure the sealed patch using pan-head sheet metal screws.
The screws should be only long enough to secure the patch to the underlying roofing panel.
Never screw the patch down through the roofing panels and into the roof decking or rafters.
This will ensure that the sealant properly seals the patch’s edges and prevents moisture from penetrating.
The patching strip should overlap the damaged area by at least 2 inches.
Apply a coating of urethane sealant over the top of the patching strip, then another patching strip.
Done correctly, both roofing panels will still be able to move independently.
Larger cracks or buckling and wrinkling often require replacement.
Rust is a red flag.
It’s a sign that your roof is aging and may need a complete overhaul.
An expert can evaluate the situation, usually determining how long your roof can last.
Also, the experts are aware of maintaining the roof up to code.
Small fixes may seem minor, but they can lead to major headaches if not done correctly.
Metal roof sealant typically lasts up to 20 years.
However, some sealants may only last 10 years (or less in damaged areas).
Check your roof after any damage occurs to determine if patches must be resealed to prevent leaks.
Metal roofs are prone to leaking at the screws when screws are not installed properly.
Yourmetal roof should last for decadeswith correct installation and occasional repairs.

It’s essential to understand if your roof warranty is transferrable with the sale of your home.
