How to Repair a Hole in a Metal Roof

Metal roofs are renowned for their strength and longevity, which is why many homeowners in the Atlanta metro area opt for steel, aluminum, or zinc roofing for long-term protection. But even durable metal roofs can develop holes over time — often due to rust, improper installation, or falling debris from Georgia’s many tall pine and hardwood trees during storms.

Whether you’re in Marietta, Sandy Springs, Lawrenceville, Douglasville, or anywhere across Atlanta, it’s important to repair metal roof holes quickly to prevent leaks, interior water damage, and mold growth.

This guide explains how to identify the problem, how to patch a metal roof hole safely, and when you should call a professional roofing contractor.

Durability of Metal Roofs

Metal roofs are among the longest-lasting roofing systems available. With proper care:

• Steel and aluminum roofs can last 40–60 years

• Zinc roofs can last 70–100 years

• Maintenance is still required, especially in Atlanta, where humidity and frequent storms accelerate wear,

However, even the best metal roof can develop problems such as:

• Rust spots

• Holes caused by debris from storms

• Leaks from improperly installed screws

• Sealant deterioration

• Panel movement from temperature swings (Atlanta summers get HOT)

Metal roof repairs should be made quickly; delaying can allow water to penetrate insulation, ceilings, and attic framing, eventually causing significant interior damage.

Common Causes of Metal Roof Holes in Atlanta

1. Falling tree limbs

The Atlanta area is full of tall pines and oaks. After thunderstorms, microbursts, or tropical weather remnants, falling branches can puncture a metal roof.

2. Storm-driven damage

Wind gusts between 40–70 mph are common in Atlanta storms. Hail and flying debris can dent or puncture metal panels.

3. Rust and corrosion

High humidity and large summer temperature swings can accelerate metal panel deterioration, especially on older roofs.

4. Improper fasteners

Loose or over-tightened screws can create holes around fastener heads.

Cost to Repair a Metal Roof in Atlanta

Costs vary depending on the damage size and whether you repair it yourself or call a professional. 

Safety Considerations

Before climbing onto your roof:

• Atlanta humidity + metal = slippery surfaces

• Check for soft or compromised decking beneath the hole

• Use secure ladders, shoes with good traction, and a safety harness

• Never work during wet or windy conditions

If you’re uncomfortable with heights or the roof is steep or tall, call a professional instead.

Tools and Materials You’ll Need

Tools:

• Metal snips

• Cordless drill

• Wire brush

• Metal file

• Caulk gun

• Putty knife

• Pencil

• Paintbrush (optional)

Materials:

• Sheet metal matching your roof material

• Urethane roof sealant (color-matched if possible)

• Pan-head sheet metal screws

• Cleaning solution (Simple Green or similar)

• Patch membrane (for raised seams)

• Paint to match the panel (optional)

How to Repair a Hole in a Metal Roof

Follow these steps for a durable, long-lasting patch.

1. Clean the Damaged Area

Remove all dirt, pollen buildup, algae, and debris using a cleaner that leaves no residue.

In Atlanta, roofs often have:

• Pine sap

• Heavy pollen films

• Mold or algae spots

Wipe the area clean and let it fully dry.

2. Scuff the Metal Surface

Use a wire brush to scrub the patch area. This helps the sealant bond properly.

Do not scuff beyond the repair area, as this may remove protective coatings and encourage rust.

3. Cut the Metal Patch

Using matching sheet metal:

1. Measure the hole

2. Add 2 inches of overlap on all sides

3. Cut the patch using metal snips

4. File the corners to round them off — this prevents lifting

Place it over the hole and mark the outline with a pencil.

4. Apply Urethane Sealant

Add a thick, even layer of sealant inside the pencil outline.

Press the patch firmly onto the sealant. You should see sealant squeezing out around the edges.
If you don’t, add more.

5. Secure With Screws

Use pan-head sheet metal screws around the patch’s perimeter:

• Space screws every 3–4 inches

• Stay within 1 inch of the edge

• DO NOT screw into the roof decking — only the metal panel

Afterwards, smooth excess sealant around the patch edges with a putty knife to ensure a watertight seal.

6. Paint the Patch (Optional)

Once the sealant cures:

• Lightly scuff the patch

• Paint to match the roof panel

This improves aesthetics and adds protection.

Repairing Holes in Raised Metal Seams

For standing-seam metal roofs (common on many Atlanta modern homes):

• Do not install a metal patch across two panels — they must move independently

• Instead, use asphalt-impregnated membrane strips

• Overlap at least 2 inches

• Coat with urethane sealant

• Add a second membrane strip on top

This preserves the roof’s ability to expand and contract.

When to Call a Professional 

Call a roofing contractor if:

•  You’re uncomfortable getting on the roof
• The hole is large or structural
•  You see widespread rust
•  Panels are buckling or shifting
•  You suspect storm damage that insurance may cover

Atlanta has many roofing companies experienced with metal roofs and storm-related repairs often they can complete a patch more quickly and safely than a DIY attempt.

Can rusted metal roofs be repaired?

Yes, minor rust can be removed and sealed. Severe rust may require panel replacement.

What’s the most common cause of metal roof leaks in Atlanta?

Improper screw installation and damage from falling pine branches during storms.

Can a new metal roof be installed over an old one?

Do metal roofs come with warranties?

Yes. Material and paint warranties can range from 5 years to lifetime, depending on the manufacturer and installer.
