It depends on the condition of your existing roof, and the quality of material used. The best thing to do is to have a qualified roofing contractor come out and evaluate the condition of your roof. It is a good practice to have a roof inspection/maintenance performed about every 3 years to clean debris out of water ways, and point out any possible problem areas before they become major issues.
WHEN IS A GOOD TIME TO CHANGE YOUR ROOF
HOW MANY TIMES HAVE YOU RAN IN AND OUT OF THE HOUSE AND GLANCED AT YOUR ROOF? IF YOU’R LIKE MOST HOMEOWNERS, RUNNING IN AND OUT AND SHUFFLING THE KIDS FROM PLACE TO PLACE, MAYBE A GLANCE FROM THE REAR VIEW MIRROR WHEN BACKING UP TO THE DRIVEWAY OR DRIVING OUT OF THE DRIVEWAY.
SO WHEN IS A GOOD TIME TO CHANGE YOUR ROOF?
1)-LEAKING OR WATER DAMAGE CAN AND DO EXIST ON CEILING, OR ALONG THE WALLS, IN THE INSULATION OF YOUR ATTIC.
2)-PEELING OR DAMAGED VISUAL EXTERIOR- CHECK TO SEE IF THERE IS MISSING SHINGLES, CURLING, BUCKLING.BLISTERING, ROTTING AND ALGAE GROWTH.
3)-SAGGING DECK-THIS IS A SURE THING TO LET YOU KNOW THAT THE ROOF HAD SUFFERED LONG TERM WATER DAMAGE AND NEEDS SPECIAL ATTENTION BECAUSE THE ROOF IS NOT DOING IT’S JOB RIGHT.
4)-OUTSIDE LIGHT SHOWING THROUGH THE ROOF-LOOK FOR THE SMALLEST HOLE OR PATH BECAUSE WHEN IT STARTS TO RAIN THE WATER WILL FIND A WAY TO GET IN THERE.
5)-DARK SPOTS AND TRAILS OR OTHER FORMS OF DISCOLORATION
6)-20-25 YEARS IS THE BEST TIME TO CHANGE THE ROOF IF IT HAS NO OTHER PROBLEMS LIKE THE TOP 5 I GAVE.
