Built-Up Roofing: Tar and Gravel

For low-pitched roofs with a slope of less than 2:12, such as on contemporary homes and commercial buildings, tar and gravel are the most common built-up roofing materials. It’s “built-up” because it is constructed of at least three layers of waterproof material that alternates with layers of hot tar. With a life expectancy of approximately 20 years, the gravel on top of the built-up layers serves to shield the roof from sun damage. Tar and gravel are not recommended as a do-it-yourself project, which is why Mainline Roofing offers expert installation services. Relax while we do the dirty work for you!

What are Snow Guards?

Snow guards or snow stoppers are rooftop devices that help prevent snow slides, by allowing them to melt completely and drop off in smaller amounts. When you install a snow guard, you can rest assured that you will benefit from a safer roofing system, less complaints of falling ice and snow, less damage to your property, and overall peace of mind throughout the winter. They are a cost-effective way to help prevent damage from avalanching snow and ice to metal roofs in winter climates. 

Use of these snow retention devices started several hundred years ago in areas of Scandinavia and the Alps. Builders and homeowners in high-snow areas placed stones and logs on rooftops to increase the friction and retention of the snow.

It’s better to use stronger and safer snow guards to prevent snow slides on people or property. Call us today for a free quote.
