In most case of scenarios, homeowners only notice red flags of needing a new roof after they spot leaking in their ceiling. Although this leak can mean a new roof is in order, there are many other factors to consider when you are trying to determine whether a repair or full replacement is in order. Here are a few things to consider:
While most experts agree that a roof can typically last between 20-25 years, this is very dependent on the quality of your current material and its install process. In many cases, homeowners find that they experience signs of aging and durability in between 15-20 years. The amount of layers you have on your roof is also something to consider. If you have more than one layer on your roof and it is older than 15-20 years old, chances are you will need a full roof replacement as your next action.
If your shingles start to curl or buckle, chances are it is also losing its granules that protect your roof shingles and in result the shingles are working past their life expectancy.
This is a sign that your roof could be failing to perform its job. Missing shingles can leave your underlayment exposed, and if left alone, elements like rain and snow can cause water to soak directly into your attic due to your underlayment being exposed.
Shingle Granules in the Gutters
Shingles tend to lose more granules toward the end of their life cycle. If you start to notice you are losing granules substantially or a darker color on some parts of your roof, this is another sign that your granules are wearing away.
Daylight Through the Roof Boards
Check your attic to see if there is any daylight coming through the plywood decking, and also see if there is any moisture in your insulation. Next, consult a professional to walk on top of your roof and if you notice a spongy feel or a bounce when walking on the roof, it means the plywood decking has been weakened from moisture over time.
Since snow and rain flow through the valleys of your roof into the gutters, it can be compromised over time and make you susceptible to roof leaks. If you notice your shingles are missing or falling apart in this area, it is most definitely means it is time for a new roof.
