What Layers Should A Roof Have?

January 14, 2024

A roof should typically have a layer of decking, underlayment, and then the outer roofing material like shingles, tiles, or metal.

Layers of a roof typically have…

Decking – Base layer providing stability.
Underlayment – Waterproof membrane protecting the decking.
Flashing – Metal strips preventing water seepage.
Roofing Material – Outermost layer providing weather protection.
Ventilation – Components regulating airflow and temperature.
Insulation –: Installed for thermal resistance and energy efficiency.
Ceiling Finishes – Interior layer providing a finished appearance.

These layers work together to create a durable, weather-resistant, and energy-efficient roofing system that protects the building and its occupants from the elements. Proper installation and maintenance of each layer are essential for ensuring the longevity and performance of the roof.
