If your roof is getting old, it may be time to replace it or repair it. First, you'll need to get a new roof estimate, and many contractors provide free roof estimates. If you would like to know more, check out these three signs it's time for a new roof estimate.

1. Leaks and Water Damage

Your roof should fully protect the inside of your home from water, but as the roof ages and experiences wear and tear, leaks can start to develop. If direct damage caused the leaks, you may see a hole on the roof, but in most cases, you'll need to look inside the house for signs of leaks. Naturally, the most obvious sign is water dripping from the ceiling, but other signs include discoloration, a musty odor, mildew, and mold growth. Mold appears as black, white, orange, green, or brown stains. They may or may not appear fuzzy. Most mold is harmless unless you have allergies or asthma, but some mold can cause illness.

2. Damaged and Missing Shingles

The shingles are the first line of defense against the weather. While they are durable, they aren't immune to damage. Common types of damage to shingles include curled edges and cracks. Both issues allow water to easily get under the shingles. UV rays and wind are the most problematic for shingles. UV rays make your shingles brittle, and wind can loosen them or dislodge them. Another common problem with damaged shingles is missing granules. In some cases, entire bald spots can develop. In many cases, however, you'll spot the granules in your gutters.  

3. Moss and Algae

Moss and algae may start to grow on your roof if you live in an area with lots of rainfall or humidity. Algae don't harm the roof, but they make it ugly by creating dark streaks. This can affect the overall curb appeal of your house. Moss, however, can pose many issues. First, the roots of the moss grow into the shingles, which can cause further damage. On top of that, the moss acts as a dam, preventing rainwater from sliding off the roof. In addition, the moss absorbs water, which increases the risk of water damage and decay. If the roof is new, you may be able to brush off the moss, but on older roofs, this can further damage the roof.

Your roof is an important part of your home, and even though it is durable, it can experience wear and tear. If you think you may need a new roof, it's time to get an estimate. For more information, contact a roofer in your area and ask about a free roofing service estimate.
