hellooo!!!
Rainwater can be collected from most roof types, depending on the quality of rainwater required.
collect from any roof material except unsealed asbestosensure all gutters fall towards the outletspreferably fit an effective leaf screen to the guttersuse gutter outlets that fit to the underside of the gutter
prevent vegetation from overhanging the roofclean the roof and gutters before installing the systemfit a good quality leaf screen to gutters or use a leaf-shedding gutter.
hope this helps you ....!!

Rainwater harvesting is the accumulation and deposition of rainwater for reuse on-site, rather than allowing it to run off. Its uses include water for garden, water for livestock, water for irrigation, water for domestic use with proper treatment, and indoor heating for houses etc.
Rainwater harvesting systems can provide water at or near the point where water is needed or used. The systems can be both owner and utility operated and managed. Rainwater collected using existing structures (i.e., rooftops, parking lots, playgrounds, parks, ponds, flood plains, etc.), has few negative environmental impacts compared to other technologies for water resources development.
Rainwater is relatively clean and the quality is usually acceptable for many purposes with little or even no treatment. The physical and chemical properties of rainwater are usually superior to sources of groundwater that may have been subjected to contamination.
@ Rainwater harvesting can co‐exist with and provide a good supplement to other water sources and utility systems, thus relieving pressure on other water sources.
@ Rainwater harvesting provides a water supply buffer for use in times of emergency or breakdown of the public water supply systems, particularly during natural disasters
@ Rainwater harvesting can reduce storm drainage load and flooding in city streets.
@ Users of rainwater are usually the owners who operate and manage the catchment system, hence, they are more likely to exercise water conservation because they know how much water is in storage and they will try to prevent the storage tank from drying up.
Typically, a rainwater harvesting system consists of three basic elements: the collection system, the conveyance system, and the storage system. Collection systems can vary from simple types within a household to bigger systems where a large catchment area contributes to an impounding reservoir from which water is either gravitated or pumped to water treatment plants.
