Commercial Metal Roof Restoration
and Repair

Extend the Life of Your Metal Roof Without a Full Replacement

Commercial metal roof restoration allows building owners to stop leaks, reinforce seams, correct fasteners, treat rust, and renew roof surfaces without removing the entire system. Metal roofs across Illinois and Iowa naturally expand and contract, which leads to loose fasteners, seam openings, panel movement, rust development, and recurring leaks. Our restoration systems strengthen these weak points and add a continuous waterproof layer that protects the building for many years.

We restore standing seam and screw down metal roofs on warehouses, manufacturing plants, schools, retail buildings, and agricultural structures. If your roof has widespread deterioration, rust, or deck issues, our Full Replacements page explains when a complete rebuild makes sense. For buildings that may benefit from a hybrid solution, systems like Roof Coatings and Spray Foam Systems provide alternatives worth exploring.

To see standards and guidelines for metal roof systems, the National Roofing Contractors Association offers technical resources at NRCA.org.

Why Commercial Metal Roof Restoration Works

Commercial metal roof restoration is effective because it reinforces the entire roof surface, not just isolated leak points. Once fasteners, seams, and rusted areas are treated, a reinforced coating system forms a seamless waterproof membrane over the metal panels. This system prevents future leaks, improves reflectivity, and often reduces interior heat load during summer months.

Metal roof restoration is ideal for buildings with:

  • Loose or failing fasteners
  • Seam separation
  • Rust or oxidation
  • Aging factory coating
  • Isolated leaks around penetrations
  • Heat transfer issues
  • Sound structural decking

If you want to compare coating systems to other roofing types, our Membrane Systems and Spray Foam Systems pages provide additional context.

Our Metal Roof Restoration Process

Roof Inspection

We evaluate fasteners, seams, substrate condition, rust, and drainage performance.

Cleaning and Preparation

Metal roofs are washed to remove dirt, chalk, and old coating residue so new systems can bond properly.

Fastener and Seam Reinforcement

Critical areas are sealed and strengthened using elastomeric materials and fabric reinforcement.

Rust Treatment

We address oxidation before applying any restoration system.

Seamless Coating Application

A high performance coating creates a continuous waterproof membrane across the entire roof.

Common Metal Roof Problems We Repair

Fastener Back-Out

Fasteners loosen due to thermal movement. We tighten, replace, and seal fasteners to stop leaks at their source.

Seam Separation

Metal seams often open over time. We embed fabric reinforcement into seams to create durable, flexible seals.

Rust and Oxidation

We remove rust, stabilize the surface, and prime affected areas before applying coatings to ensure strong adhesion.

Panel Movement

Expansion and contraction cause panel shifts and leak paths. Restoration systems help stabilize these areas.

Leaks Around Penetrations

HVAC units, vents, and pipe boots are common leak points. We install reinforced waterproof details where leaks are most likely to occur.

When Restoration Is the Right Choice

Metal roof restoration is recommended when:

  • The roof deck is structurally sound
  • Rust is limited to surface-level corrosion
  • Leaks are caused by seams or fasteners
  • You want to avoid the cost of a replacement
  • The building has heat management issues
  • You want a renewable system with long term benefits

If structural concerns exist, a replacement may be needed. Visit Full Replacements to see how we approach full rebuilds.

FAQs

How long does commercial metal roof restoration last?

A restored metal roof often lasts 10 to 20 years depending on coating type, weather conditions, and maintenance.

Can a metal roof be restored instead of replaced?

Yes. If the roof deck is solid and damage is limited to seams, fasteners, or surface wear, restoration is usually the best option.

Will a restored metal roof handle Illinois and Iowa weather?

Yes. Reinforced coating systems are designed to withstand heat, rain, snow, wind, and freeze-thaw cycles.

Does restoration improve energy efficiency?

Yes. Reflective coatings reduce heat absorption and help control interior temperatures.
