Understanding the Commercial Roof Restoration Process

When it comes to maintaining commercial properties, a startling fact is that nearly 40% of all building issues stem from roof problems. This makes commercial roof restoration not just a want but a necessity. In this post, we’ll take you through the intricacies of the commercial roof restoration process, uncover the benefits, and offer tips on choosing the right roofing company for your needs.

What is Commercial Roof Restoration?


Commercial roof restoration involves rejuvenating an existing roof system to extend its life. Unlike a complete roof replacement, which involves tearing off and installing a new roof, restoration focuses on cleaning, repairing, and adding a protective coating to the existing roof.

Types of Roofs Suitable for Restoration

Certain types of roofs are more amenable to restoration than others. Here are the most common:

  • TPO (Thermoplastic Polyolefin): Popular in commercial roofing due to its energy-efficient properties.
  • EPDM (Ethylene Propylene Diene Monomer): Known for its durability and flexibility.
  • Metal Roofs: Often chosen for their longevity and strength.
  • Modified Bitumen: A reliable choice for low-slope commercial roofs.

Scope of Work

Commercial roof installation and restoration generally involve several stages:

  • Comprehensive inspection
  • Cleaning and preparation
  • Repairing damaged sections
  • Applying a restorative coating

Benefits of Commercial Roof Restoration


Restoration is significantly less expensive than complete roof replacement. Here’s a comparative table:

Activity Average Cost per Square Foot
Roof Replacement $7 – $12
Roof Restoration $3 – $6

Environmental Impact

Roof restoration is eco-friendly. By opting for restoration, you can reduce the amount of roofing material waste that ends up in landfills. Restored commercial roofs can also incorporate sustainable materials and coatings.

Energy Efficiency

Reflective coatings, often used in commercial roof restoration, help lower energy costs by reflecting sunlight and heat. This energy efficiency translates into reduced HVAC costs for your building.

Extended Roof Lifespan

Restoration can add 10–15 years to the life of your commercial roof, making it a worthwhile investment.

The Commercial Roof Restoration Process

Initial Inspection and Assessment

Before any work begins, a thorough inspection is crucial. Professional roofing companies use tools such as infrared thermography to detect hidden moisture and other issues.


The roof must be clean before any restoration process can be successful. This generally involves:

  1. Debris Removal: Clearing leaves, branches, and other debris.
  2. Surface Cleaning: Using specialized cleaning agents to remove dirt and grime.


Next comes repairing any damage. Common steps include:

  • Fixing leaks
  • Sealing cracks
  • Reinforcing weakened areas

Application of Coatings

This is a critical step in the restoration process. The type of coating depends on the type of roof:

  • Silicone Coatings: Ideal for weather resistance.
  • Acrylic Coatings: Useful for UV protection.
  • Polyurethane Coatings: Excellent for durability.

Final Inspection and Quality Check

The final stage involves a thorough quality check to ensure the restoration was successful. This typically includes:

  • Leak tests
  • Visual inspections
  • Infrared scans

Selecting a Roof Restoration Service Provider

Qualities to Look For

When choosing a roofing company, consider:

  • Licensing and Certification: Ensure they are properly licensed.
  • Insurance and Warranties: Check for adequate insurance and robust warranties.

Experience and Expertise

Opt for companies with a proven track record in commercial roof restoration. Ask for references and review past projects.

Cost Estimates and Contracts

Properly evaluate cost estimates by comparing multiple offers. Look for clear and detailed contracts to avoid hidden costs.

Multiple factors influence the cost of commercial roof restoration:
