Tar and Gravel roofs are also known as also known as ‘built-up’ roofs. Tar and Gravel roofs contain 3 to 5 layers of asphalt sheet bases, tar and roofing felts to create a membrane that is resistant to water and UV damage.
Overtime, tar and gravel roofs can become susceptible to water damage and crumbling. It can cause puddling on a roof when it is not properly fixed and can break up over time without routine maintenance. But with proper inspection and replacement, tar and gravel roofs can last 20 to 25 years.
Tar and Gravel roofs are built to keep water and UV rays out of the home. The hot asphalt and tar mean high insurance for any damage that night happen. Check on your roof every six months and remove any fallen debris. These roofs are vulnerable to mold and plant growth. So removing seeds and other plant debris is beneficial for the life of the roof. Adding gravel may also come in handy when some of the roof starts to slope off and leave asphalt exposed to the elements, which can lead to cracking.
Tar and gravel roofs are built with guiding drains called scuppers, which lead the water to the drains and off your roof. Routine maintenance of adding gravel or apply rubber tar patches to your roof can be done every six months. At the end of your roof’s life, the layers can be scraped away and rebuilt while the old roof can be recycled for asphalt shingles or road pavement. Many asphalt roofs are recyclable and reduces the amount of waste in landfills.
Mildew and rot are major concerns following water damage to a roof. Mildew spots can be washed in a mixture of bleach and water. But rot would have to be replaced.
