1. What is the current age of your roof?
Most professionals agree that a typical roof will last between 20 and 25 years. If you had your old roof replaced or had a contractor install an additional layer of new shingles installed over old shingles. If this is the case then your roof is probably older than 25 years. It most likely doesn't have the proper ventilation and may have damaged plywood. Contact WF Schmidt Construction Company for a free estimate!2. Are your shingles curling/buckling?
Shingles that are curled or buckling are another sign that you may need a new roof. If your shingles are curled and buckled most likely your roof is past the life expectancy. Call WF Schmidt Construction Company for a free estimate!
3. Roof Valleys
Roof valleys are designed to and carry the greatest volume of water on your entire roof system. If you are missing shingles in the valley area then you will most likely have a leak.
4. Missing shingles
Take a look at your roof to see if you have any missing shingle tabs. If you do, make sure you get them replaced as soon as possible. Water will go underneath the missing tabs and cause water damage to your roof decking and eventually soak your insulation and damage your drywall.
5. Chimney flashing
Your chimney flashing is definitely one of the first things that will deteriorate due to the roof cement that is used. Roofing cement does not last 25 years. You will need to maintenance this area throughout the roof's life. If you don't keep this maintained eventually the tar and roof cement will fail. All chimney flashing should be ground into mortar.
6. Shingle granules in the gutters
If you see shingle granules in your gutters most likely your shingles are worn out.
7. Daylight through the roof boards
If you ever get up on your roof and walk around and notice that there is a soft spot in your roof decking, this is generally a sign that your plywood roof deck is damaged from water. If you have an attic access, go up to see if there is any plywood that is discolored or if you see light coming through the plywood.
