Metal roof repair costs by problem

Full replacement $5 – $16 per square foot

Cost to replace metal roof screws

The cost of replacing metal roof screws or fasteners is $150 to $1,000, depending on the number of screws. Thermal expansion and contraction cause the fasteners to loosen or back out over time, reducing the roof's resistance to wind and moisture.

Resealing metal roof seams

Resealing metal roof seams costs $250 to $1,100, depending on the number of seams repaired. Most roofers use a silicone caulk gun or tape to seal against moisture and leaks. The silicone adheres to metal and allows expansion and contraction with temperature changes.

  • Non-curing caulk is used to seal cracks, gaps, and joints between panel seams and metal laps.

  • A tape sealer made of butyl is used anywhere there is a metal-to-metal connection that is not fastened off to compress the two pieces of metal together.

  • A combination of tape and caulking is used around roof penetrations like chimneys, vents, or pipe boots.

Cost to replace metal roof panels and sections

Replacing metal roof panels costs $3 to $14 per square foot on average. More expensive metals like copper cost up to $30 per square foot to replace.

  • Metal-over-metal retrofits installed directly over the damaged roof save on labor costs and provide a secondary layer of protection.

  • If the metal has deteriorated or the structure can’t support another roof layer, the old roofing must be removed and replaced.

Metal roof coating prices

Metal roof coating or sealing costs $0.50 to $4.00 per square foot and provides a secondary barrier against moisture and UV damage. Most roofers prefer silicone sealants, which adhere to metal and allow thermal movement. Sealants last from 10 to 20 years with proper installation and adequate cure time.

A PVC membrane costs $4 to $10 per square foot to cover flat roofs. The membrane is watertight, withstands ponding, resists mold, and reflects heat. A PVC membrane lasts 25 years when properly installed.

Metal roof painting

Metal roof painting costs $1.20 to $2.70 per square foot to clean, seal or prime, and paint the metal. Painting a metal roof improves the roof's appearance, energy efficiency, and lifespan.

Oil canning metal roof repairs

Oil canning is a visible distortion or buckling seen in the flat surface of the metal panel between the standing seams. Oil canning occurs in all types of metal and is an aesthetic problem that doesn't require repairs. To prevent oil canning, hire an expert installer and:

  • Select a thicker gauge metal.

  • Use a striated or ribbed panel to deflect light and hide imperfections.

  • Ensure level roof decking before installation.

  • Properly store materials out of the elements before installation.

  • Allow for thermal movement of the fasteners.

Metal roof leak repair cost

Metal roof leak repairs cost $200 to $1,000 on average. Leaks from rust or corrosion cost up to $3,000 to repair. Most leaks result from poor installation, occurring along the seams, fasteners, or roof protrusions. Repair costs increase when the leak source is difficult to find.

Price to repair metal roof gaps, cracks, and holes

Repairing gaps, cracks, and holes in a metal roof costs $200 to $900. Minor cracks and holes are fixed with epoxy sealant, rubberized tape, or a repair patch. Major gaps require removing and replacing the membrane and roof panels to ensure leak protection.

Metal roof rust and corrosion repair costs

Metal roof rust and corrosion repairs cost $300 to $3,000 on average. Metal roofing panels are coated to resist rust, but small areas of rust eventually leak. Minor repairs include sanding off the rust, priming, and painting the surface. Severely rusted panels must be removed and replaced.

Storm damage repair costs on metal roofs

Homeowners insurance typically covers storm damage repair costs. Metal roofs are hail-resistant, suffering only cosmetic damage in most cases. Deep hail dents may cause punctures and leaks, and extreme winds lead to loosen seams and fasteners.

Metal roof maintenance costs

Metal roof maintenance costs $75 to $1,200 per year or about 1% to 3% of the total cost of a new roof installation. Routine service plans help prevent potential problems, extend the roof's lifespan, and maintain the manufacturer's warranty.

Metal roof maintenance service cost
Service type Cost Frequency Maintenance tasks
Surface maintenance $75 – $400 Every 12 – 18 months
  • Clean off dirt, mildew, and other stains
  • Clear gutters and drains of debris
  • Remove branches and tree limbs that touch the roof
  • Touch-up surface scratches with a paint pen
Structural maintenance $225 – $1,200 Every 1 – 2 years
  • Check the fasteners, rivets, and screws and tighten or replace them as needed
  • Check for loose or separating panel seams and reseal as needed
  • Touch up or replace sealants around panel junctions
  • Check around all penetration points and repair as needed
  • Look for punctures or dents from fallen debris
