Many flat roofs are stabilized by putting small stones on them. These rocks, sometimes called river gravel, are smooth and won’t cut into the roof when you walk on it. Then, tar is applied. This material has a low melting point and tends to melt away easily in hot summers, but the stones make it stay put. In the end, this is a cost-effective method for many purposes.

Why Do They Put Rocks on Roofs?

Stabilization of flat roofs

Stabilization of flat roofs with rocks is a common practice for built-up roofs. Rocks and gravel are both great options because they provide protection to the flat roof and help balance the weight of the roof. Rocks also add a decorative element to the roof, which many homeowners appreciate. The most popular flat roof material is rolled roofing, which is made of TPO, Thermoplastic Polyolefin, EPOM, or rubber. These materials are widely used because they are cheap and easy to install.

Another option for flat roofs is installing turf or grass. Grass serves as a natural UV barrier and helps absorb water. Soil on the roof also serves as an additional heat barrier, helping to maintain an even temperature year-round. However, not all flat roofs are durable enough to be walked on. Flat roofs are ideal for buildings that want to reduce energy costs, while also increasing comfort.

Protection of tar paper from sun, hail, errant baseballs

Roofs with rocks and gravel are increasingly popular as an environmentally friendly roofing option. The stones help keep the tar paper in place and prevent it from buckling or blowing away in high winds. In addition to providing protection from the sun, rocks and gravel also provide ballast to the roof. Here are some reasons why rocks and gravel are important:

Collecting rainwater

Many homeowners are interested in energy efficient solutions for collecting rainwater, and the simplest of these solutions is to collect it on your roof with rocks. Although this method is not ideal for every roof, it is an effective way to collect water without the need for additional structures. All that is needed to collect rainwater is a roof and a drainage system. Larger rain barrels or water tanks can be constructed around the roof and can store sufficient water to meet household demands. Several farmers and ranchers are adopting energy-efficient techniques in order to collect rainwater.

When collecting rainwater from roofs, install a funnel to collect the clean water. Use PVC, plastic, or some other inert substance to protect your pipes. This is important because rainwater has a low pH, which can lead to corrosion and mobilization of metals. Ensure that the funnel is made of plastic or other inert substance. If the water collected is too dirty, a simple first flush can improve its quality.

Another important factor to collect rainwater is the type of roofing material. You need a roof that is suitable for collecting good quality rainwater. Some surfaces may not be suitable, but others may be more suitable for collecting rainwater. It is vital to consider the location and local regulations before deciding which material to use. If you are collecting rainwater for drinking, check with the local government or council before installing any rocks on your roof.

Collecting rainwater with rocks on roof is a low-cost, yet effective solution. Rock catchments should be situated in areas where access is easy. Geological structures should be considered as well as the length of dry periods. The ideal location is lower-lying inselbergs. This approach minimizes runoff losses to vegetation, structures, and soil. It can also be installed in open tanks.

Unlike conventional drinking water, rainwater is free of man-made pollutants and airborne particles. This type of water is free of man-made pollutants such as smoke and ash from fires. Therefore, collecting rainwater is a great way to save money and protect the environment. It will also help you conserve potable water. If you collect rainwater with rocks on your roof, you will not have to worry about the evaporation and contamination of water.

Ferrocement tanks are larger and cheaper than basket tanks. They do not require waterproof cement mortar. Ferrocement tanks were the first jars made in the community, and were used to train local masons in jar construction. A ferrocement tank is a concrete or ferrocement cylinder. In addition, mortar jars can be used to collect rainwater. It is a simple method, but requires some upfront work.
