Yorktown NY Roofing: Article About A Roof's Life Expectancy
Unfortunately, homeowners do not get an instruction book that tells them when it is the right time to repair a roof or when it is best to replace it. There are many factors that need to be considered when making this decision. Most homeowners consult a Yorktown NY roofing contractor for an expert opinion.
Homeowners should know the life expectancy of the type of roofing system they have when deciding to repair or replace. Sheet metal roofs have a life expectancy of approximately 25 to 50 years. Asphalt shingles can last from anywhere between 12 and 25 years. Slate roofs as well as metal roofs may last for a century or more. Climate, the frequency of maintenance, the quality of installation, and wear and tear will affect a roof's longevity.
Once homeowners have this information, they can begin to calculate where their roof is according to its life expectancy. A roof with three tab asphalt shingles that is in its twentieth year of use has reached an age where replacement may be the preferred option. On the other hand, a slate roof that is 20 years old is just at the start of its deterioration timeline.
Another factor homeowners will consider is the nature of the damage to their roof. Isolated leaks can be repaired. Systematic leaks are more problematic. Repairing them is just a temporary fix.

Homeowners are concerned about the safety and well being of their family. Any indication that roofing problems could lead to a roofing collapse, the growth of dangerous mold, or any other problem that would affect the health of the home's occupants would cause a homeowner to immediately replace the roof.
The main reason why homeowners delay in replacing their roof is the expense. A good way to calculate if it is in a homeowner's best interest to replace his or her roof as opposed to doing minor repairs is to take the total cost of the roof replacement, divide it by the number of years they expect to live in their home, and then compare this number with the cost of doing minor repairs. If the cost of replacing the roof divided over the expected years of occupancy is equal to or more than the cost of replacing the roof, then replacing the roof would be in a homeowner's best interest.
It is understandable that homeowners are reluctant to invest in replacing their roof. However, the above mentioned guidelines serve as a way for homeowners to make an objective evaluation of the condition of the roof and then make a decision that is in their long term best interest.
