What Causes Water Damage to the Ceiling?

Often the source is from the roof, which makes sense considering all the wear and tear it goes through. Common sources of leaks involve cracking in the flashing, broken or damaged shingles, bad sealing, ice dam buildup, clogged gutters, or improper installation.

Heavy winds and hard rain can cause considerable damage to shingles, and so can just general erosion based on the sun. This deterioration can start with the flashing, which can become exposed when the tar completely corrodes.

Valleys, or the low area in your roof, are especially weak to rain leakage. Improper sealing or installation of any part of the roof can result in leaks springing much earlier than expected. Entropy is the number one enemy and it is especially effective against shoddy craftsmanship.

When a ridge of ice forms on the edge of the roof, it can create a dam that blocks snow from running off, eventually melting into water. Clogged gutters work similarly, causing water to get blocked up and run down the sides of the house, causing even more leaks.

While not as common, it is possible that your roof might be fine but a leaking or bursting pipe might be causing the water damage in your home. This is especially relevant for basements and any home on the side of a hill. Usually curved pipes like U-bends are the source of the leak.

While you don’t necessarily need all of these tools, the more you have the easier your job will be. Try having a combination square, tape measure, taping blade, and jab saw on hand. A cordless drill, joint compound, drywall tape, and sanding sponge will help you put it in.

Before you paint, make sure you apply primer first, as any smaller stains that you haven’t cut out will show through even the best paint. Once the primer is completely dried, hit it with some paint. Try applying a thin coat to the whole ceiling to get a uniform color.
