Shingles

Shingles are flat, rectangular roofing cover that is widely used because of its economical upfront cost, durability and easy installation. Shingles are typically laid in lines that go vertically up the roof, with each subsequent course overlapping the joints below. Shingles are made with different materials like metal, wood, slate, plastic, fibre cement and some with composite materials such as asphalt shingles.

Eave

Eave is the horizontal, lowest edge of a sloped roof that extends beyond the exterior wall of a building. It is used to keep the water off the wall but is also used for decorative and architectural purposes.

Fire Rating

It is a system based on test methods developed and perfected by standards writing organizations used to classify the fire resistance of a certain material. Fire ratings for roofs are classified as Class A, B and C with A being the most fire resistant. A roof can also have an unrated fire rating classification if it was not able to meet any of the requirements for Class A, B or C.   

Dormer

It is a small structure that juts out from the top of a sloping roof or a larger roof plane that houses a window or ventilating louver.

Rafter

Rafters or members are a series of sloping beams from the ridge to the down-slope perimeter or eave, or the supporting framing member right under the deck.

Deck or Sheathing

Deck is the structural surface of the roof to which other roofing materials are applied. It is the foundation upon which the entire roofing system depends on. It is usually made up of plywood, wood boards, planks or oriented strand board (OSB).

Blistering

Blistering are the bubbles or pimples you can see in roofing materials after installation. Blistering is usually caused by moisture under the material or moisture trapped inside the roofing material brought on by rain or snow.

Drip Edge

A noncorrosive and non-staining piece of material installed along the edge of a roof or eaves and rakes to allow water to drip clear of underlying construction or areas that could be damaged. Drip Edge is required on all Atlanta roofing installs.

Flashing

Flashing are thin pieces of impenetrable materials – they could be aluminum, galvanized steel, plastic or composite material. Flashing is installed around any projections or intersections used to prevent water seeping in and causing damage.  Depending on the style of roof, flashing could be used on valleys, vent pipes, chimneys, dormer windows or skylights.

Cricket

Cricket, oftentimes called saddle, is a water diverter constructed at the back of a chimney that helps prevent accumulation of snow and ice between the chimney and the roof. It is also used to deflect water around the chimney but can also be used on other roof projections.
