Basic Roofing Components

Decking

The base surface of your roof to which everything else is attached. Typically made from plywood or oriented strand board (OSB).

Shingles

The outermost layer of the roof, available in various materials like asphalt, wood, and metal, providing weather protection and aesthetic value.

Underlayment

A water-resistant or waterproof barrier material installed directly onto your roof deck. It provides an extra layer of protection from severe weather.

Flashing

Thin pieces of waterproof material installed to prevent water from entering at joints or valleys in your roof, typically around vents, chimneys, and skylights.

Advanced Concepts

Ice and Water Shield

A specialized underlayment that protects against ice dam and driven rain leaks, typically used in cold climates.

Ridge Vent

A vent installed along the ridge line of the roof to allow warm, humid air to escape from the attic, promoting a cooler roof temperature and extending the life of the roof.

Eaves and Rakes

The eaves are the edges of the roof which overhang the face of a wall and, typically, project beyond the side of a building. The rakes are the angled edges that run from the eaves to the ridge.

Installation Techniques

Step Flashing

A method used at the intersections of walls and roof lines to ensure water flows away from the wall and into the shingle system below.

Valley Installation

The method of installing shingles in the roof valleys, where two roof planes meet. This can be done in a closed or open style, each providing different aesthetic and functional benefits.

Conclusion

By understanding these key roofing terms, homeowners can navigate their roofing projects with greater ease and assurance.
