A roof drain defined as a drain that receives water collection on the surface of a roof and releases it into a downspout, lead, or conductor. A roof drainage system is a system that is installed on the roof to debris off the roof, and divert water. Roof drains are used to remove excess water, which is usually caused by rain. Two types of roof drain that are well-known and installed are primary or the main roof drains, and overflow or secondary. Roof drains are usually required for not sloping roofs, and flat or semi-flat roofs. Roof drains are usually made of cast iron, metal, or synthetic materials that include grates to prevent branches, solids, and debris from draining into the roof drain system.

Key factors that are anticipated to fuel the demand for roof drain during the forecast period, are growing demand for roof drains during construction due to the expected intensity of the rainfall, rising demand in commercial applications, increasing ponding and damage from water overflow or leakage boosted the use of roof drains, availability of a variety of roof drain materials in the market for numerous industrial applications.

However, the most expensive of the types of flat roof drains is a, due to the pipes are inside the building, Lack of awareness among consumers and stringent regulations of roof drains are expected to restrain the market. Penetration of the product into untapped countries of Asia Pacific, and Environment-friendly roof drains and growing government support is creating opportunities in the market.

As per Growth Market Reports industry analyst Divyanka Sankhe, “The Roof Drain Market is expected to witness substantial growth during the forecast period 2021-2028. Growing disposable income and rising commercial construction are propelling the market. In the roof drainage sector, the demand for roof drains is growing, which is expected to drive the market”.

Growing demand for roof drains during construction due to the predictable intensity of the rainfall. Roof drains are required in various industries, including real estate, healthcare, and industrial applications, to protect buildings during rainy season and stop water leakage. Roof drains suitable for low slope roof and flat applications on new and existing constructions are available to specify for construction use. Urban rainwater drainage systems are unable to release large amounts of runoff into collecting reservoirs after heavy rainfall, resulting in local floods.

The global economic expansion is projected to continue in the next decade, fueled by the growth of developing industries that are expected to deal with heightened international, and economic, such as temporary suspension caused by trade hostilities between China and the US. Covid-19 affected the construction industry in multiple ways, such as raw material, supply chain disruptions, operation cancellations, and office shutdowns as a result of the lockdowns imposed. These factors decreasing production activities and declining growth of the economy hampered the market growth.

A supply chain is a system among a company and its suppliers to manufacture and allocate a specific product to the final buyers. This network includes different people, entities, information, and resources. Entities in the supply chain include producers, logistics, vendors, finance, warehouses, and customer services. Presence of major suppliers and distributors, adoption of technologies, convenience of raw materials, and presence of an integrated logistics industry are some factors that boosted the growth of the supply chain in industrialized countries such as the US, Canada, etc.
