Don't wait to think about your roof until it's too late.
According to the National Roofing Contractors Association, homeowners should perform a regular roof inspection twice a year: spring and fall. Homeowners should remove any debris like leaves or sticks from rooftops, drains, gutters and downspouts. While doing so, homeowners should take a visual inspection of the tiles to see if anything looks out of the ordinary.
Homeowners should take a look at their records to see when the last time the house had its roof replaced. A typical asphalt shingle roof lasts for about 20 to 25 years. If the roof has been installed over existing shingles, it typically reaches the end of its life after about 20 years.
Homeowners should pop up into their attic to get an inside look at a roof's status. If, under the eaves, there are beams of light coming through, that could indicate spots for leaks. Or, if there are streaks or strains, it could indicate a leak at some point.
Another way to check on the useful life of a roof is to look at the shingles. They should lie flat against the roof and be free of cracks, damage and buckling. If any of those issues are happening, it may be time to look into repairs.
Finally, if you do see some spots that need attention, contact a professional. It may not mean you need a whole new roof. It could just mean a few repairs are in order. Either way, a licensed roofing contractor can help you determine the best route.
