Expert Metal Roof Repair Services

Our team restores metal roofs to a clean, watertight condition. We fix leaks, replace a damaged metal roof panel, correct fasteners, and repair flashings—so small problems don’t turn into costly interior damage.

As a roofing contractor trained on every metal roof system, we handle sloped roof projects, metal roof leak repair, and long term maintenance. We use professional metal roof sealant and roofing sealant compatible with your roof material, stopping rust and corrosion before they spread. If a metal roof panel was improperly installed or the existing finish has deteriorated, we can apply a protective coating to strengthen the surface for years to come.

Need help now? We offer emergency leak repair and routine maintenance using proven methods and manufacturer-approved materials.

We service all roof types: standing seam, corrugated, ribbed, aluminum roof repair, and architectural panels—residential and commercial.

Signs You Need a Repair (Before It Leaks Inside)

  • Stains on ceilings or around skylights/vents
  • Loose or missing fasteners / exposed gaskets
  • Separated end-laps or open seams
  • Rust/oxidation spots around screws or panel edges
  • Wind or hail dents, punctures, or bent flashings

The most common leak points on metal roofs are fasteners, penetrations, and end-laps. We locate the source, fix it, and verify with a final water test.

Metal roof inspection and maintenance

Took storm damage? Don’t wait—moisture spreads fast under panels. Call for a same-day inspection and temporary dry-in.

DIY Kits, Tape & Sealants vs Professional Repair

DIY products (kit, tape, store sealant)

  • Quick patch for a drip, but often fails after heat/cold cycles
  • May trap moisture or void warranties if misapplied
  • Good for temporary stop-gap only

Professional repair (recommended)

  • Fixes the cause: fasteners, seams, flashing, or panel damage
  • Uses pro-grade sealants/coatings with proper prep and cure
  • Backed by workmanship and manufacturer warranties

Repair vs Coating vs Replacement

Repair

Best for specific leaks, localized rust, or damaged flashings. Extends life quickly at a low cost.

Coating

Ideal when the roof is mostly sound. After point repairs, an elastomeric coating seals seams and boosts energy performance.

Replacement

Chosen for widespread corrosion or end-of-life panels. We’ll price both repair and replacement so you can compare.

What Is the Most Common Leak on a Metal Roof?

The most frequent leaks happen at fasteners, seams, and penetrations. Over time, screws can back out, gaskets wear down, and seams pull apart from thermal expansion. Flashing around vents, skylights, and HVAC curbs is another weak point. These areas open tiny gaps that let water in during heavy rain or snowmelt.

Left unchecked, small drips can spread into decking and insulation. Annual inspections are the best way to catch these issues early before they turn into interior damage.

Quick tip: stains near skylights, damp spots by HVAC units, or rust around screw heads are the first signs of trouble.

What Is the Best Way to Seal a Leaking Metal Roof?

The best fix depends on where the leak is coming from. For seams and fasteners, pro-grade silicone or urethane sealants paired with reinforcement tape create a watertight bond. For larger problem areas, it’s better to replace damaged panels or apply a full elastomeric roof coating system after targeted repairs.

DIY caulk or store-bought tape can work as a short-term patch, but they rarely last through seasonal heat and freeze cycles. Professional sealing ensures proper prep, adhesion, and warranty-backed results.
