If you are noticing leaks in your home or drafty areas in an attic, these may be signs that your need a new roof. You should always have a professional come to take a look. What is it that they will identify?
The first thing that a professional will check for is shingles that are peeling up on the edges. This happens in many older homes and is not a good sign for insurers.
Poor adhesion can create significant damage to the house during a storm, so an insurer would not want to take on your home. When shingles are able to fully pull up, water will seep in and create leaks. This is definitely something to get fixed, especially if you plan on selling soon.
Any tree debris left after a storm can become acidic and degrade roof components at a faster rate. This will result in uneven aging of your roof and will require repairs far earlier in some cases. Try to get all your debris off your roof after a storm. This is a good time to perform your yearly inspection.
