Gravel Roof

Definition

A roof composed of layers of roofing felt for waterproofing, then sealed with tar or pitch and covered with a layer of gravel to assist in protection from wear and the sun.

Purpose

Gravel roofs provide a durable, weather-resistant roofing solution that protects underlying materials from UV radiation, physical wear, and extreme weather conditions.

Examples of Use

• Commercial Buildings: Common in flat or low-slope roofs for their durability and cost-effectiveness.
• Industrial Facilities: Used to protect extensive roofing surfaces from environmental damage.
• Residential Buildings: Employed in flat-roofed homes for long-lasting protection.

Related Terms

• Built-Up Roof (BUR): A multi-layered roof system, often finished with gravel or other protective materials.
• Roofing Felt: A material used in waterproofing roof layers.
• Tar and Pitch: Materials used to seal and waterproof roofing systems.

Notes

Gravel roofs require regular maintenance to ensure the gravel layer remains evenly distributed and to check for any potential leaks or damage.
