The Anatomy of a Commercial Roof

The Anatomy of a Commercial Roof

When conducting business, as usual, you probably don’t think about your roof that much. You just trust that it will provide protection against leaking and water damage as well as cold or warm air drafts.

The only time it concerns you – and rightfully so – would hopefully be during inspection time and not during an emergency. Understanding the anatomy of a commercial roof will confirm that your contractor is providing you the repair service you need.

Important Commercial Roof Components

The anatomy of a commercial roof consists of multiple layers of support, and each roofing level serves a unique purpose. Your next routine inspection will ensure all these components are intact so you continue to provide uninterrupted service to your patrons and clients.

An inspection will also alert you of any issues that require attention, and this gives you the chance to make necessary repairs. Evaluating the condition of each part of your roofing layers could even prevent having to replace your roof.

Structural Deck

This layer serves as the main support for the entire roof. It’s a primary component of many flat commercial rooftops. Steel is one of the most popular structural deck materials, and it encompasses the other supportive and protective layers. Alternative structural deck materials include wood, concrete and gypsum.

Vapor Control Layer

This thin protection layer prevents moisture from traveling to the insulation layer. Think of it as additional lamination that you might not easily spot when viewing a rooftop but will prevent all kinds of damage, including mold growth. The VCL also prevents water damage, and this slows the presence of interior destruction.

Insulation and Adhesive

The adhesive, which is usually made of rubber or comparable bond material, attaches your insulation to the weatherproof layer above it. Insulation is what helps you maintain a manageable indoor climate no matter how cold or hot it is outdoors. Insulation is usually made of polyiso, polystyrene or high-density gypsum materials. 

Weatherproof membrane

This thin layer that is often made of PVC or TPO materials not only provides a water barrier but it also absorbs heat from the sun that otherwise might be wasted. An alternative coating frequently used is black EPDM rubber or built-up roofing partly made of asphalt substances. 

Importance of Not Delaying Maintenance

Regular inspections at least once a year will alert you of fixes you need to make. Having your commercial roof fixed after natural disasters and harsh storms without delay is also important. It all starts with spotting the problems before they progress and taking care of it. The maintenance that comes after the inspection potentially extends the life of your rooftop to several decades from the initial purchase.
