Roofing Educational Guide

Types of Roofs

Gabled Roof

The easiest and most cost-effective option for both roofer and homeowners.

Hipped Roof

Their strength make them popular in regions that have high winds and extreme winter weather.

Gambrel Roof

Common on barns and sometimes used on houses because it creates lots of attic space.

Combination Roof

Includes gables and hips and is popular in new construction.

Flat Roof

Most often used on commercial buildings and more modern and contemporary homes. Requires specialized knowledge and materials.

Parts of a Roof

Decking: the first layer on top of the home’s rafters.

Underlayment: a thick water-resistant material that helps protect the roof’s decking from moisture.

Soffit and ridge vents: allow air to enter the attic under the eaves and exit from the top of the roof for proper ventilation.

Fascia: when they’re correctly installed together, soffit vents and fascia seal the roof preventing pests from getting into the attic while still allowing air circulation.

Flashing: is typically installed around dormer windows, skylights, vents, and chimneys and helps to keep water out of the roof.

Roofing Materials

Asphalt shingles
Wood shakes and shingles
Metal
Slate, clay, and concrete

Roofing Issues

LEaks

Most often caused by failed flashing around vent pipes, skylights, or chimneys.

Ventilation

Improperly vented roofs allow heat and moisture to build up in the attic and can cause mold and mildew growth, rotting, and overheating.

Waves in Roof

Can be caused by normal settling of the house, shingles being installed over existing shingles, or rotted decking.
