In case there are rooms having doors and windows with no chhajja or overhang which prevents rain water from coming into the rooms, it is necessary to add a protective overhang over such openings. Ideally a proper chhajja should be made over such openings, incase major breakage and civil work is not possible, then I will give you a few suggestions of the kind of structures you can build over such doors and windows. In case you are looking for a readymade structure available in the market you could go in for an awning. Several reputed companies are making these and these can be fabricated to the length required by you, also you could go in for either one continuous awning or in parts to suit your requirement. Most awnings are retractable or collapsible and therefore can be opened as and when required.

Secondly you have the option of getting a structure fabricated. The framework can be of metal or wood and it may be continuous or in parts as per your requirement. In metal you have the option of an aluminium framework or a mild-steel pipe or box section. Over this basic framework you can have a covering of a fibre-glass or polycarbonate sheet. These sheets are available in both plain, patterened or corrugated form. This would be screwed over the framework. Polycarboate is however a more expensive option. It is a harder material and over a period of time is less prone to shrinkage or warpage in sunlight. You have the option of putting clay brick tiles as well. These come in various colours ranging from terracotta, green, bluish grey etc. Make sure while installing any such structure, the necessary slope is given to drain of the rain water. Incase you go in for a wooden framework over a period of time it may absorb moisture and this may lead to cracks or some degree of warpage in the wood. Both metal and wooden frameworks can be painted in any colour as per taste.
