Look in your gutters to see whether they are loaded up with shingle granules. Roofs tend to lose more granules toward the end of their life cycle. Inconsistant or darker color on some parts of the roof is another sign the granules have worn away.

Why You Need a New Roof

Indications of moisture

If your roof shingles are falling apart or missing in this area, it's a definite sign you need a new roof. Valleys are one of the most important areas of your roof. Snow and rain flow through valleys and into gutters. If the valley is compromised, you could be susceptible to roof leaks.

You notice a spongy feel or trampoline bounce when walking on the roof, which means the underlying decking is weakened from moisture. Check your attic to see if there is any daylight coming through the roof boards. Also check for moisture in the insulation.

Curled or buckled shingles

​Missing or damaged shingles

Moisture indications are a serious issue and failure to take immediate action can result in increased damage and replacement costs. 

These are another sign your roof could be failing. Check to see if all of the shingle “tabs” are intact. 

This is another area to be concerned about. If your flashing consists of roof cement or tar, it may need to be replaced with a long-term, water-tight fitting, which would be a metal flashing system.

How old is your existing asphalt shingle roof? Most experts agree that a typical roof will last between 15 and 25 years. It also depends on whether the old roof was removed and you only have one layer of shingles, and if it is properly ventilated along with many other variables. If the roof was installed over another layer or several layers and it is older than 15 years, chances are you need a new roof.

You see daylight through the roof boards

Shingles that are curled or buckling are another sign that you may need a new roof. Look at the slopes of your home that get direct sunlight and if you notice the shingles are curling and losing granules, it could mean the shingles are past their life expectancy. There could also be a possibility that the roof is defective. Contact a licensed roofing contractor to see if you could be eligible for reimbursement.
