When you’re considering hiring a commercial roofing contractor, you may be interested in learning about the different parts of a roof. Knowing commercial roof anatomy can assist you in asking the right questions to your roof contractor before, during, and after installation. Commercial roofing systems are complex and require a detailed understanding of their various components to ensure proper installation and maintenance.

This is why you want to rely on experienced and professional commercial roofers near Lexington, KY, to install a commercial roof for your business. The ABR Construction roofing team has put together this guide to explain the different parts of the roof and provide insights into each component and its function.

Commercial Roof Anatomy

1. Roof Deck

The roof deck is the structural base of the roof. It supports the entire roofing system and typically features materials such as plywood, metal, or concrete. The deck must be sturdy and properly installed to support the weight of the roofing materials and withstand weather conditions.

2. Vapor Barrier

A vapor barrier is an important part of commercial roofing, particularly in areas prone to high humidity. This layer prevents moisture from penetrating the roof deck, which can cause damage over time. The vapor barrier is usually installed above the roof deck and below the insulation.

3. Insulation

One of the most important parts of a roof, insulation is essential for maintaining energy efficiency in a commercial building. It helps regulate the building’s temperature, reducing heating and cooling costs. Common insulation materials include rigid foam boards and spray foam. Commercial roofers near Lexington, KY, place the insulation above the vapor barrier to keep the building warm in winter and cool in summer.

4. Roof Membrane

A waterproof layer of a commercial roof, the roof membrane protects the building from water infiltration. There are various types of roof membranes, including single-ply membranes like TPO (thermoplastic olefin), EPDM (ethylene propylene diene terpolymer), and multi-ply systems. The choice of membrane you choose typically depends on factors like climate, building structure, and budget.

5. Flashing

Flashing seals and protects joints and edges on the roof. It prevents water from seeping into the building at vulnerable points such as chimneys, skylights, and vents. Flashing typically features metal materials and is a critical component of the roof anatomy in preventing leaks and water damage.

6. Drainage System

Proper drainage is essential for commercial roofs to prevent water buildup that can lead to structural damage and leaks. A drainage system includes gutters, downspouts, and internal drains designed to channel water off the roof efficiently. Routine maintenance of the drainage system is crucial to ensure it functions correctly.

7. Roof Covering

The roof covering is the outermost layer of the roof anatomy and provides the first line of defense against the elements. Common materials for commercial roof coverings include metal panels, asphalt shingles, and roofing tiles. The choice of covering depends on the desired aesthetic, durability, and specific needs of the building.

8. Roof Penetrations

Roof penetrations are openings in the roof for various installations, such as HVAC units, vents, and skylights. Each penetration must be adequately sealed to prevent water intrusion. Because roof penetrations are potential weak points in the roofing system, they require careful attention during installation and maintenance.
