10 Most Common Roofing Terminologies
It can be daunting to choose a new roof, especially if your knowledge of roofing terminology and their meanings is limited. Here are 10 common roofing terms and definitions that are useful for roofing. An educated consumer is always better.
Clay Tiles
Clay tiles have been one of the most durable and long-lasting roofing materials. Clay tiles were used in early American settlements that date back to the 1500s and in St. Augustine, Florida by Spanish settlers. These tiles are very durable, even in harsh sunlight, heat, strong winds, and heavy rains. However, they are lightweight and put less strain on roofs when properly installed. Clay tiles are fired at nearly 2,000 degrees, making them durable and fade-resistant. Clay tiles have a typical life expectancy of 50 years.
Concrete Tiles
Sometimes, concrete is used to create roofing tiles with a similar appearance to traditional clay tiles. This can be seen on Spanish and Mediterranean-style roofs. Concrete tiles are more affordable than clay tiles and can come in many colors. They can last for several decades if they are properly maintained.
Deck
The roof’s supporting structural component is the deck. The deck of a roof is like a floor upon which other layers such as waterproofing membranes or shingles are placed. The deck of the roof can be hidden under the visible roof or above the attic.
Drip Edge
A drip edge is a structure that runs underneath the roofing material and extends beyond its edge. A drip edge allows water to flow on a smooth surface until it reaches the roof’s edge. Once it reaches the roof’s edge, it can flow into the gutters.
Elastomeric Cover
A continuous roof protection barrier that protects a roof from water damage is an elastomeric roofing coating. It can be either a rubberized roof coating membrane or an acrylic roof coating membrane. These coatings can be used on flat roofs to reflect solar heat and reduce cooling costs. This protective layer is durable and can withstand severe weather conditions.
Flashing
Flashing is a material that’s designed to seal roof surfaces where there are gaps or cracks in the roof. Flashing is required to cover any openings in the roof surface that are created by vent pipes or chimneys.
Impact Resist
Impact resistance is a measure of the roofing material’s ability to resist damage caused by falling objects and people walking on it. Impact resistance is the measure of how resistant a roof is to being pierced by falling branches or people walking on it.
The lap is a part of a roofing or waterproofing component that overlaps with another area of the roof.
Layering
Roofs are actually a series of layers that act as a protective barrier against elements like rain and wind. It is similar to laying clothes in winter. You only need one or two layers underneath your outer clothing to keep you warm. It can be difficult for a new roof to fit over an older roof’s layering. It is possible to repair a roof with additional layers. However, it is best to completely remove all layers and start over with a new roof.
Steel Roofing
Metal roofs have been around for hundreds of years. They are making a comeback due to their lightweight, which reduces the strain on your home’s structure. Metal roofing systems are extremely energy-efficient and can be ordered in many colors. They will often outlast traditional shingled roofs by many years. Metal roofs are durable and last a long time, so insurance companies offer homeowner discounts if they are installed.
Ridge Vent
The roof’s ridge is the area at the top of the roof. A ridge vent allows heat from the attic to escape by installing a device along the vertical ridge. A ridge vent is a great idea for those who have moisture problems or live in hot areas where heat cannot escape. This will result in less efficient cooling.
As the name suggests, the underlayment is a layer beneath the exterior layer. It is usually made from asphalt-saturated felt or other materials. The underlayment is attached to the roof deck to help keep water out and add an extra layer of protection.
