A tar and gravel roof is a durable and cost-effective option, commonly used for flat or low-slope roofs. This type of roofing consists of multiple layers of tar, asphalt, and gravel, which provide excellent protection against water and harsh weather conditions. Its layered design helps with insulation, reducing energy costs. Additionally, tar and gravel roofs are fire-resistant and can withstand extreme temperatures. Maintenance is relatively simple, and they have a long lifespan when properly maintained. This roofing system is also ideal for commercial buildings due to its ability to handle heavy foot traffic. However, it may require occasional maintenance to prevent damage from debris or wear.
