When looking at your roof, there are obvious signs that you can look for that it needs to be repaired as soon as possible, such as missing shingles that have exposed the underlying decking. However, even if your roof is fairly new, there are still issues that can arise that could make repairs necessary that are easy to miss.

If you do miss these issues, they could become widespread and create a situation where your roof will need extensive repairs or even need to be replaced. Below are a couple of early warning signs of roofing damage that you need to have repaired before the problems get worse.

1. Small Blisters Are Forming on the Surfaces of a Small Patch of Shingles on the Roof

One early warning sign that your roof has damage is when you see small blisters form on the surfaces of the shingles. These blisters are created when the shingles' material expands and contracts, causing small pockets of air to form.

As time goes by, these air pockets will become bigger, allowing moisture to become trapped inside of them and cause rapid deterioration of the shingles. If caught early for repairs, the affected shingles can be replaced by a professional before they cause major damage to the decking and other parts of the roof.

2. Flashing on the Roof Has Started to Show Signs of Corrosion

Another sign you should be on the lookout for that indicates a potential problem area is when the flashing around the chimney, vent pipes, and other structures starts to show signs of corrosion. You will usually find that small areas have turned a rust color, indicating that oxidation is taking place.

Since the flashing is vital for keeping water from flowing into vulnerable areas of the roof, if the rust eats through the metal, the situation can cause massive leaks. If caught early, however, a roofing professional can either remove the rust and treat the metal or replace the affected flashing.

If you notice that the shingles have started to blister and/or the flashing is showing early signs of corrosion, you should not delay in having the issue repaired. If you wait too long, the problems will become widespread, which could make it necessary to replace the entire roof instead of having it repaired.
