According to most roofing experts, a good roof can last up to 30 years. At any rate, it is essential to determine the exact age of your roof, in order to have realistic expectations about its durability and maintenance issues. If you find the exact age of your roof you can anticipate potential problems and thus prevent them.
A good way to find out the age of a roof is to ask its previous owners about it. In this respect, it is highly recommended that you do not cut off all contacts with the previous owners of your home. Most homeowners are more than willing to answer any questions about the state of a house, and this may include the exact time when the roof was repaired, replaced or installed.
Finding the building permit is another good method of finding out the truth about your roof. In case the area you live in requires a permit for roof installation, then you can ask for a copy of that permit. There you can find the exact date when your roof was installed. A permit is the most reliable source of information in this respect as is one of the good Wichita roofing contractors.
Another thing you can do is ask for a copy of the receipt from the roofing company that did the work.
