Your house is one of the most important possession as a property and building. It holds significant monetary value as well as sentimental one. It is the resting place after a tiring day in the office, a safe place where you can stay warm and sleep (well, expect earthquakes), a convenient place to enjoy the food etc. As anything you love, you must take care of it. Same for your house. If it is damaged or the roof is needs a repair, do some maintenance and contact an expert or general contractor.
