Denver Roofing: Article About Causes Of Ceiling Cracks
Cracks that form along the walls of a home may indicate a problem with the foundation. As the foundation moves and shifts, it puts undue pressure and stress on the walls, and cracks form as the walls separate from the foundation. Cracks that form on the ceiling and move down along the walls usually indicate a leak in the roof rather than a problem with the base of the building. These cracks are a serious sign that shows the leak existed for a longer period of time than homeowners were aware of. Even if the leak is more serious, Denver roofing companies can offer homeowners some solutions.
The cracks that homeowners see in their ceilings can range in size from just a few inches long to several feet long. The size often depends on the severity of the leak and how long it existed. As the water slowly drips down from the roof, the ceiling attempts to adjust itself to support that water. Homeowners may notice that the ceiling develops a saggy appearance as the excess water causes it to drop down. When the ceiling can no longer accommodate that moisture, a crack will form.

If the water continues falling from the roof, the crack will lengthen and widen, and it may even split open.
There are a few reasons why a leak of this kind might form, but the most common reason is due to missing shingles. Those shingles keep moisture off both the roof and its underlayment, but when the shingles go missing, the underlayment becomes exposed to rain and other elements. Something as simple as a squirrel running across the roof might rip open the underlayment and leave the roof exposed to moisture from rain and snow. Broken or cracked shingles can leave the underlayment exposed as well.
Homeowners who find smaller cracks in their walls and ceilings can look for other signs that might indicate there is a leak on the roof. One is the presence of black, brown or green mold that grows on or inside the walls. Depending on the humidity level in the home, they may find mildew growing in addition to or instead of mold. Homeowners will also want to check the roof deck for any mold or mildew. Mold on the deck is a clear sign that there is standing water on the roof. That standing water can add enough pressure that it breaks through the ceiling and leaves behind cracks and leaks.
