In the construction industry, roofs are essential components that provide protection against the elements and contribute to the overall design of the building. It is important to research the different components that make up a commercial roof and understand the terms used when discussing these elements. A commercial roof components glossary can help when it comes to navigating the parts and making the most informed decision when constructing or renovating a building. In this article, we provide an overview of the various components that may comprise a commercial roof, their functions, and some of the common terms used.
Underlayment
The underlayment is an essential part of any roof as it is the barrier between the roof and the deck or insulation. It is found below the roofing material and provides additional water-resistance and weather protection. Depending on the type of roofing material and design, the underlayment can be felt paper, self-adhering modified bitumen, non-bitumen fabrics, and more.
Roof Deck
The roof deck provides the base for the entire roofing system and is the foundation for the insulation and roof covering. It is typically made of plywood or OSB (oriented strand board) and is often placed on top of a sub deck.
Air & Vapor Barrier
The air and vapor barrier, often installed at the same time as the roof deck, provides an additional layer of protection against water intrusion and helps reduce energy costs by decreasing air leakage and preventing moisture damage. This barrier is typically made of polyethylene film or polypropylene fabric.
Ridge Vent
The ridge vent is a type of ventilation system installed on the ridge of a roof that helps to regulate the air flow within the attic and to expel the hot air outside. It helps reduce the load on the HVAC system while also preventing the buildup of humidity and moisture in the attic. The ridge vent should be aligned with the eave vent to ensure optimal air flow.
Eave Vent
The eave vent is a ventilation system that is typically installed in the eaves or soffit of the building and helps to regulate the air flow in the attic. It draws in cool air from the outside and helps to direct warm air out of the attic. This prevents the buildup of heat and humidity in the attic and helps reduce energy costs.
Shingles
Shingles are a type of roofing material that is composed of a base felt material and asphalt, a layer of minerals and a saturant, and usually a colored ceramic mineral coating. Shingles provide additional protection and weatherproofing, come in a variety of colors and designs, and are relatively easy to install.
Metal Roofs
Metal roofs are composed of metal panels installed over a solid substrate and fastened securely with clips and screws. Metal roofs are popular in commercial applications due to their strength and durability, ease of installation, and fire resistance.
People Also Ask
What are the components of a commercial roof?
The components of a commercial roof vary depending on the type of roof and specific design, but typically include an underlayment, roof deck, air and vapor barrier, ridge vent, eave vent, shingles, and metal roof panels.
How do you install a commercial roof?
The exact installation process for a commercial roof depends on the type of roof, but generally includes steps such as preparing the substrate, installing the underlayment and vent system, attaching the roof covering and flashing, and installing insulation and final touches.
What is the purpose of a ridge vent?
Ridge vents are designed to help regulate the air flow in the attic and to expel hot air outside, reducing the load on the HVAC system while also preventing the buildup of heat and humidity and reducing energy costs.
What is the difference between shingles and metal roof panels?
Shingles are made of a base felt material and asphalt, with a layer of minerals and saturant, and often a colored ceramic mineral coating. Metal roof panels consist of metal panels installed over a solid substrate and fastened securely with clips and screws. Shingles are less durable than metal roof panels, but are also less expensive and easier to install.
Final Words
When constructing or renovating a building, it is important to understand the different components that make up a commercial roof and their specific functions. From underlayment to shingles and metal roof panels, this article provides a comprehensive overview of common commercial roof components, their functions, and the language used to refer to them.
