The first homes were huts, caves, and lean-tos that only existed to protect humans from the elements. This is still their first purpose. Your roof's job is to protect you, your family, and your belongs from water. It's essential that your roof is waterproof.

Making a watertight roof is not easy. There are special waterproof membranes that are only laid on your roof starting at the bottom. Roofers seal every single nail hole against rain. Shingles overlap each other in a particular pattern to allow water to run off the roof, instead of soaking into the roof. A single unsealed nail hole can cause a leak:

Small Leaks Can Cause Big Damage

Finding a leak is not as straightforward as you may think. Because most roofs slope, where the water drips may actually be far from the source of the leak. This means you could repair the worn place, leaving the source.

How much time do you spend in your attic? If you notice a leak in the living areas of your home, that leak has probably been around for a while. The longer you have a leak, no matter how small, the more complicated repairs are.

Repairs get more complicated because mold, mildew, and rot have damaged more parts of your roof. Mold and mildew can ruin beams, floors, and insulation. Even the smallest leak, left long enough, can cause the wood in your attic to rot.

Occasionally, an animal moves into your attic. After animal control leaves with the animal,the roof will need some repair. An animal not only tears up the waterproof membrane and insulation for its nest, but waste and stored food means that massive replacement is in order.

Regular Maintenance Prevents Major Repairs

Every spring and summer, take a walk around your home. If possible, take a flashlight, pen, and paper with you. Look for rust spots (especially with metal roofs) and curling, broken, or missing shingles. Is there mold, moss, or sagging? Are there holes that animals could use? Anything you notice you should write down.

Next, go up to the attic. With the flashlight, check for dark and damp spots and streaks. This means that water is present and beginning to mildew or rot the wood. Are any dark spots soft or wet? Look around for puddles or other water damage. Are there any soft spots are you walk around? Add what you find to the list.

Once you have a list, call professional roofing contractors. They have the skills and knowledge to help your roof keep you and your family safe and dry.
