I don't believe that limestone is a disinfectant for water.
You are most likely to see a gargoyle on a historic building or a church, typically on the exterior walls or roofs. Gargoyles were commonly used in medieval architecture to serve as decorative water spouts to divert rainwater away from the building.
Houses in Goa have sloping roofs to help with drainage during the monsoon season, to prevent water from accumulating on the roof. The sloping design also helps to keep the inside of the house cooler by allowing hot air to rise and escape. Additionally, the sloping roofs are a characteristic feature of Goan architecture influenced by Portuguese colonial style.

Metal roofs are generally more expensive upfront compared to composition roofs. However, metal roofs are more durable and have a longer lifespan, which can result in cost savings in the long run due to lower maintenance and replacement costs. Additionally, metal roofs can increase the value of your home.
If an extremely thick amount of ash falls on building roofs, it will cause them to collapse due to the extremely heavy weight.
Rain water is collected through a process named Rainwater harvesting. Here rainwater that falls on the roofs are collected through pipes and ultimately stored in large tanks. These are called harvesting tanks also.
The advantages of having green roofs on schools is that they are environmentally friendly. They absorb rainwater, provide animal habitats and provide insulation.
Also known as "living roofs", green roofs serve several purposes for a building, such as absorbing rainwater, providing insulation, creating a habitat for wildlife, and helping to lower urban air temperatures and combat the heat island effect
Common types of pipes found on roofs include vent pipes, soil pipes, and rainwater pipes. Vent pipes allow air to enter the plumbing system to prevent vacuum and odors. Soil pipes carry waste from toilets and sinks to the sewer system. Rainwater pipes collect and direct rainwater away from the roof to prevent water damage.
Collecting rainwater from roofs was often a convenient and cost-effective way to obtain clean water for household use. It eliminated the need to access potentially contaminated water from rivers or wells, which may require treatment or purification. Additionally, rainwater is a naturally soft source of water that is ideal for activities such as watering plants or washing clothes.
Stalactites - comprised of the mineral calcite, and although not all limestone caves contain stalactites, these formations always hang from the roofs otherwise they would not be stalactites!
The more humble homes were made of adobe, generally they were made of limestone though.
Rainwater harvesting is the collection and storage of rainwater for future use. This involves capturing rainwater from roofs and other surfaces, directing it to a storage system, and then using it for purposes like watering plants, washing, or for non-potable uses in a sustainable manner. It helps to reduce reliance on mains water supply and conserve water resources.
Bermudas landscape is hilly with no lakes or rivers or streams but we reside in the Atlantic ocean. Bermuda depends on rain water, underground lens and pureification plants for our water supply. Bermuda has a tank system it works in this format. As the rain hits our roofs runs into the gutter and down through the pipes and into our tanks. This was edited by malachi ... Thank you!
Rooftop rainwater harvesting is a method of collecting rainwater that falls on roofs and directing it to storage tanks or reservoirs for later use. This collected rainwater can be used for various purposes such as landscaping, irrigation, flushing toilets, or even for drinking after proper treatment. It is a sustainable and eco-friendly way to conserve water and reduce reliance on traditional water sources.
There are two types or rainwater haversting. Rooftop rainwater harvesting and drain harvesting. In rooftop rainwater harvesting, we use the water collected on rooftops instead of letting it go down the drain. We can also use water collected in dugout ponds, underground vessels etc. Drain harvesting involves letting water collected in roadside drains go straight to the ground. But this water has to be treated before use as it may contain bird faeces, germs and other pollutants.
Ancient Egyptians often built flat roofs to accommodate the hot climate, allowing for better air circulation and the possibility of using the rooftop for leisure and sleeping during warm nights. Flat roofs also facilitated the construction of homes and temples, maximizing usable space. Additionally, they served practical purposes, such as collecting rainwater and providing areas for solar drying of crops.
