Asphalt and gravel roofing is a traditional type of roofing that is often used for residential, commercial and industrial roofing.
This multi-layer roofing system, composed of a membrane of several thicknesses of saturated felts, is loaded with liquid asphalt between each layer. The last layer is covered with gravel to protect the asphalt from solar radiation.
The advantages of an asphalt and gravel roof include durability, weather resistance and sound dampening. It can also be more cost effective than other types of roofs, making it a popular choice for many home and building owners.
However, an asphalt and gravel roof requires regular maintenance, including removing debris, moss and leaves that may have accumulated or moss that may have grown on its surface. If not regularly maintained, it can deteriorate more quickly and require costly repairs.
Tar and gravel roofs are a cost-effective solution for buildings like multi-unit dwellings, where the roof needs to be installed around HVAC units and other accessories. White gravel can be used in urban areas to reduce heat islands.*
*A white roof has long-term economic and environmental benefits. Because the white cladding reflects the sun’s rays rather than absorbing them, the membrane will not overheat, preventing premature deterioration and reducing air conditioning costs. This effect also helps reduce heat islands in urban areas. TPO, elastomeric and tar and gravel roofs all have white options.
