Metal Roof Repair: How The Pros Patch Up Metal Roofs

June 26th, 2024 BY First American Roofing

Metal roofs offer a multitude of benefits for residential homes, making them a popular choice among homeowners:

However, even the best metal roof systems need occasional repairs. In this comprehensive guide, we will dive into how professionals patch up metal roofs, ensuring longevity and durability for your home.

Why Patch a Metal Roof

Over time, various kinds of damage can occur on a metal roof, causing it to need a patch. Here are three common types:

  1. Corrosion: Despite being treated to resist rust, metal roofs can eventually corrode if the protective coating wears off. This is particularly common in coastal areas or environments with high humidity. Corrosion can compromise the integrity of the roof, leading to leaks and other issues.
  2. Holes: Holes can appear on metal roofs for various reasons, such as falling debris or improper installation. These openings need to be patched up quickly to prevent water from seeping in and causing further damage.
  3. Loose Seams: As metal roofs expand and contract with temperature changes, seams between panels may become loose over time. This can allow water to enter and cause leaks if not addressed promptly.
  4. Leaks: Leaks can occur due to improper installation, damaged seams, or punctures from falling debris. Over time, these leaks can cause significant water damage inside the home.
  5. Loose Panels: Windstorms and other extreme weather events can loosen metal roof panels, compromising the roof’s integrity and waterproofing capabilities.

Addressing these issues promptly is crucial to maintaining the roof’s performance and extending its lifespan. Regular maintenance and repairs can also save you money in the long run, as metal roof repair costs tend to be fewer than those associated with a full roof replacement.

How It’s Done

Patching a metal roof involves several detailed steps. Here’s how professionals do it:

  1. Safety first: Ensure all safety gear is worn properly. Secure a ladder or scaffolding to access the damaged area safely.
  2. Assess the damage: Thoroughly inspect the roof to identify all damaged areas. Use a marker or chalk to outline the sections that need repairs.
  3. Clean the area: Use a wire brush to clean the damaged area. Remove any rust, debris, or old sealant to ensure the patch adheres properly.
  4. Cut the patch: Using metal snips, cut a piece of metal from the patch kit to fit the damaged area. The patch should be large enough to cover the damage with an additional 2-3 inches on each side.
  5. Apply sealant: Apply a generous amount of roofing sealant around the perimeter of the damaged area. Ensure the sealant covers any holes or gaps.
  6. Place the patch: Place the cut patch over the damaged area, pressing it firmly into the sealant.
  7. Secure the patch: Using a screwdriver or drill, secure the patch with roofing screws. Place screws approximately 1-2 inches apart around the perimeter of the patch.
  8. Seal the edges: Apply additional roofing sealant along the edges of the patch to ensure a watertight seal. Smooth the sealant with a putty knife if necessary.
  9. Inspect the repair: After the sealant has dried, inspect the patch to ensure it is secure and watertight. Reapply sealant if any gaps or weak points are found.
