Are you thinking about replacing that warehouse roof? Hold on – you might want to consider a retrofit instead. Many owners and managers find that retrofitting is not only practical, but easier on the budget, too. At Vanguard Roofing, we’re here to help you weigh all your options so you can make the best choice for your facility.
What Is The Difference Between Commercial Roof Replacement & Retrofit?
A full roof replacement includes removing all existing roofing materials, exposing the deck underneath, making necessary repairs, and building an entirely new roof system. In general, a roof retrofit consists of installing a new roofing system over the existing one. When retrofitting a building with a metal roof, the existing metal roof can be used as the roof deck. Insulation is added, and the new roofing system is installed, completing the retrofit project.
The Benefits Of A Roof Replacement Versus Retrofitting
- A new roof allows for inspection and repair or replacement of the underlying structural layers and components.
- A new roof enables the roofing contractor to identify and address any hidden moisture, ventilation, or insulation problems.
- A new roof allows the warehouse owner to upgrade to newer, more efficient materials.
- A new roof provides warehouse owners full manufacturer (and, in some cases, labor) warranty coverage.
The Difficulties Of A Roof Replacement Over A Retrofit
- The existing roof remains in place and provides a structural base for a new overlay.
- The cost of retrofitting an existing roof is significantly lower than a roof replacement.
- Retrofitting the current roof allows for faster installation with minimal disruption.
- A retrofit can be an affordable opportunity to enhance the building’s energy efficiency.
The Advantages Of Choosing A Retrofit Instead Of A Roof Replacement
- A new roof typically costs two to three times more than retrofitting a roof.
- A new roof might take significantly longer to install compared to a retrofit.
- A new roof may produce more waste due to removal and disposal processes.
- A new roof can lead to additional disruption of building operations.

The Challenges Associated With Retrofitting Rather Than A Roof Replacement, And How Vanguard Roofing Addresses Them
- Retrofitting the existing roof might not resolve underlying moisture or structural issues. We use infrared technology to scan the existing roof to ensure there are no hidden moisture issues before proceeding with a retrofit.
- Opting for a retrofit could create compatibility issues and potentially worsen future problems. At Vanguard Roofing, we research your existing roofing components and determine the most compatible manufacturer to ensure there are no compatibility issues.
- While a retrofit may extend the life of the current roof, it will not do so for as long as a complete roof replacement.
