Unless you’re buying a new construction home, the age of a home’s roof should be a big factor in your home buying decision. If the roof exhibits any of the below signs, you’ll need to make sure there’s room in the budget for a replacement roof.

If the roof is coming up on 25-30 years old and looks to be in good condition, it might still need a replacement. Waiting to replace a roof until it’s too late can present a host of issues that you don’t want to deal with as a homeowner.

Many times, homeowners can get away with roof repairs, depending on the condition and age of the home. However, when a roof needs a complete replacement, it will show the following signs.

Shingle Edges Curl

If any shingle edges appear to curl, the roof will need an inspection to determine whether the broken shingles can be replaced, or the entire roof needs a replacement. Curled shingles are lengthy sun exposure and drying out the material.

Missing Shingles

Shingles that are missing from your roof are exposing your home to the elements from outside. If water enters the home because of the missing shingles, you’re in for issues that will need immediate attention.

Neighbors Starting to Replace

Pay attention to your neighbors’ roofs. If it seems to be a trend that roof replacement is occurring left and right in your neighborhood, it’s probably time to replace yours soon considering the majority of homes are likely built around the same time period.


Any type of water damage is a nightmare in homeownership. If water spots are found on your ceiling, it could be a sign of water intrusion as the result of a roof leak. If water spots are overlooked, it can cause additional issues like wood rot and mold.

Shingle Granules

If shingle granules are found missing, this is a sign that your roof is no longer effectively weatherproofed. When the granules start falling off, they can collect in the gutters. Missing granules are a good indication that it’s time for a new roof.
