St Louis Roofing: Article About Warning Signs Of Roof Collapse
Certain types of damage to a roof can lead to leaks and broken or missing ceiling tiles or parts of a ceiling. Though some might feel confident enough to live in their homes with buckets or large pots collecting the water coming through the ceiling, leaving those leaks is extremely dangerous. The longer those leaks remain, the more water damage it can leave behind. That water damage can cause the entire roof to come down, and fixing a collapsed roof is often quite expensive. St Louis roofing companies know how to identify the signs that a roof might collapse and what to look for when inspecting both the interior and exterior of a home.
During an interior inspection, roofers will look for cracks in the ceiling. Homeowners do not often pay attention to ceiling cracks when shopping for a new home, or they see the cracks and assume the previous owners fixed the problem. Some unscrupulous sellers will use a joint compound and apply that compound to the cracks without fixing the underlying cause of the problem.
Those cracks occur because of excess water and the weight of that water.

Any moisture that gets through the shingles, underlayment and membrane will land on the drywall used on the ceiling or on the insulation. The water softens the drywall and exerts enough pressure that it forms a crack. Some homeowners may notice that parts of the ceiling appear bowed. This usually occurs because there is water in the ceiling that hasn't yet broke through.
Cracks found in ceilings can range from a few inches long to three feet long or longer. As long as residents continue ignoring the problem, the cracks can keep growing and expanding before finally coming down and causing the collapse of the ceiling.
Another sign of a possible roof collapse is rotting of the membrane and support structures. Excess moisture can cause green mildew to form on the structure or leave behind traces of brown mold. Those substances weaken the supports, and when those supports can no longer hold the roof up, it will come down.
There are a number of repairs that can stop a roof from collapsing, including the installation of a reinforced membrane. This usually requires the removal of old shingles from the roof and the installation of multiple layers of tar paper and other materials before laying new shingles. Though reinforcing the membrane is typically pricey, it often costs less than replacing the whole roof.
