National Roof over Your Head Day takes place on December 03, 2022. It is a day to appreciate the things we have, including the roof over our heads. A roof is the covering on the uppermost part of a building or shelter, to provide protection from the weather, notably rain, but also heat, wind and sunlight.
The primary job of most roofs is to keep out water. The large area of a roof repels a lot of water, which must be directed in some suitable way, so that it does not cause damage or inconvenience. Because the purpose of a roof is to protect people and their possessions from climatic elements, the insulating properties of a roof are a consideration in its structure and the choice of roofing material.
