Reason for rocks on roofs.

Some buildings have have rocks on the roof of it. There are different types and weights of gravel used on flat roofs for these purposes. It is very important to note that the amount of gravel being applied to a roof must be precise it depends on the specific roofing spec being used and the building type. They hold down the tar roof by their weight they prevent uv damage and erosion of the tar and asphalt paper and limit debris that can stick to it.

The gravel prevents sun hail errant baseballs etc from damaging the membrane the all important moisture seal created by the tar paper and tar. The stones keep the tar paper in place and prevent it from buckling or blowing away in a high wind. Gravel is used on flat roofs for two reasons. Incorrect installation is often the primary reason roof shingles get blown away.

Generally the weight for a gravel coated roof must be within 10 25 pounds per square foot. The shingle manufacturer provides specific areas where the installer is required to fasten the nails and if they are not careful while doing their work you may end up having roof shingles that are nailed too high and face the risk of them not being caught adequately by the nails making them less wind resistant. Rocks break up snow and ice to prevent injuries from the snow and ice sliding off the roof when the temperature warms up. No picnicking or grilling on the grounds vehicle roofs or hoods please.

The rocks gravel serve several purposes. One of the top reasons why is slate used for roof tiles is that they are environmental friendly.

Having slate tiles prevent owners from replacing their roofs every 20 to 30 years for it can reach up to a hundred years with proper installation and regular maintenance.

Too much gravel can result in a structural issue due to weight. That s all there is to it. Rocks gravel are for ballast weight to hold the roofing material on and to reflect heat and sunlight to prolong the life of the roof. One is to hold water and let the sun heat up the rocks and evaporate the water another to protect the roofing from uv rays which will help the roof last longer and there is also an architectural look that is achieved when building green roofs.
