Roofing has become such a complex science that it’s developed a language all on its own. With so much technology and so many different materials, processes, and hazards to look out for, it can be difficult to keep up with what’s going on and what your roofer is telling you, unless you’re an experienced Fort Worth commercial roofer yourself. If you find yourself confused or unsure of what your roof inspector is telling you about the roof over your head, you may benefit from learning what a few of the common roofing terms mean.
Here is a brief glossary of common commercial roofing terms.
Buckling: This is the term used to describe warping or wrinkling of your roof’s surface.
Deck: This is the base layer of your roof that the roofing materials are applied to. In most homes and some commercial structures the deck is made of plywood, but other materials, including metal, have also been used as well in commercial applications. This is also sometimes called “sheathing.”
Flashing: These are pieces of metal or another waterproof material used to prevent water from leaking into your structure or damaging your roof near intersections or protrusions like vents, chimneys, valleys, or joints.
Membrane: This is a flexible or semi-flexible sheet, usually made of plastic or bituminous material, which waterproofs your roof.
Penetration: This is anything that passes through your roof from inside, including a vent, chimney, pipe, conduit, or even supports for your air conditioner or heater.
Pond: These are water puddles on your roof that sit stagnant and don’t drain naturally with the slope of your roof.
Rafters: The framing built out of either wood or metal that the deck of your roof is attached to. These are the primary support provider for your roof.
Slope: This is the angle at which your roof is sloped in order to allow water to run off or towards drains or gutters during rain. This is measured in the number of inches in rise per foot of horizontal run.
Surface: This is the outermost layer of your roof, which provides the first line of protection for it. These can be a number of different materials with various levels of durability and protection.
Underlayment: This is a sheet of material, often saturated with asphalt, that’s used as a secondary layer of protection for your roof deck.
Valley: This is where two planes intersect, creating a low-point that’s usually subject to a lot of water exposure during rainy seasons. These are typically only found on structures with sloped roofs.
Vapor Retarder: This is a layer of waterproof material installed in your roof that’s designed to prevent water from passing through your roofing materials and into your structure.If your commercial roof needs work, call Bronco Roofing & Construction today at (817) 241-2303!
