Do you view your roof as invincible? It might feel that way, particularly right after you ride out a rough storm. Still, there are some signs of wear that could lead to hefty repair fees if left unattended. 

But how do you know when it's time to call in a professional to inspect your roof? Here are four signs that you might want to have your roof looked at soon. 

1. Critters in the Attic

Hearing odd noises in your attic? It's possible that a bird or squirrel has managed to come in through a crack in your roof and has made your home their home. 

You may also find signs of water damage or debris in your attic if there are holes large enough for animals to come inside. 

A roofer can seal off your roof to block excess moisture or animals attempting to enter your crawl space.

2. Dark Spots

Notice darker areas on your walls? It's likely water that has seeped in and is starting to dry. Over time, this can begin to destroy the walls and can lead to mold growth.

Be sure to have someone look at your roof immediately if you notice wet spots so you can keep the damage from accumulating. 

3. When It's Time to Sell

After you've owned your home for many years, you may decide it's time to let it go and move on to a new space. 

To prepare your home for buyers, you will want to have your roof inspected so they can patch up any issues that could depreciate the value of your home.

4. It's Chilly

Provided your home is properly sealed, you should never notice a sudden swoosh of cool air when the heater is on.

If you find yourself reaching for a sweater when you were perfectly warm before, and you know your heater is working, you may want to have your roof looked at to make sure there aren't any rogue cracks that are allowing warm air to escape. 

And, of course, if you see any exterior damage to your roof, don't brush it off as being something you can deal with later. It's always best to catch problems early so that you don't have to worry about water damage to your belongings.
