Retrofit Metal Roofing System

Are leaking roof penetrations, failing metal roof seams, or rusted roof decks compromising your business operations?

Upgrade your Metal Roof through Retrofitting

Considering retrofitting your metal roof for your commercial or industrial building? 

Retrofit metal roof systems give you a cost effective solution as well as long term protection your building. 

Let us help you determine if this roofing system is the right decision by providing a comprehensive, no obligation rooftop evaluation for you.

What is a Retrofit Metal Roof?

Metal retrofit roofing involves the installation of infill, then an overlay of insulation to create a flat surface for the single-ply roofing membrane. Essentially you are adding a new metal roof over your older, existing roof.

This process adds insulation value and avoids the high cost and risk of exposing your building and operations to “blue sky” by removing and replacing the existing metal. 

The flexible single-ply membrane covers your existing metal roof, providing a dry, solid roof system. Also, a properly installed membrane protects your metal roof from further corrosion.

Cost-effective Metal Roofing System

This proven metal roofing system provides a cost-effective, long-term means to end roof leaks and provides energy savings as a secondary, financial benefit to your business. 

Additionally, we have custom prefabricated flashing and deck sheets available to reduce on site labor, leaving more of your capital investment in the roof system, not in labor that drives away after your project is completed.

Allowing Sentry to install a membrane metal retrofit roof will reduce maintenance costs over time and are backed by manufacturer warranties to provide ease of mind in your investment.

Plan Ahead & Prevent Disaster;
Commercial Metal Roof Repair

As many of you know, the maintenance of metal buildings and roofs, particularly in the Midwest is challenging due to rain, temperature changes, and ice buildup, which can result in corrosion and interior leaks. 

Additional damage to the metal roof is caused by constant movement of the metal due to temperature related expansion and contraction. 

If such damage is left unaddressed, leaks may damage inventory, equipment or supplies and be a hazard to staff, possibly causing major disruption or cost to your business.

Allow us to inspect your metal roof to prevent a failure or leak from causing an unplanned interruption to your business. 

We will inspect your facility to determine the nature of the problems, and help you determine what course of action may be needed, whether you need your commercial metal roof can be repaired or replaced through retrofitting.
