Toledo Roofers: Article About Roofing
Once moisture makes its way into the wooden structure of a roof, it is only a matter of time until the wood decays and begins to rot. Rotting wood will cause serious structural problems within the home, along with the potential for significant health and safety concerns for the occupants of the structure. Understanding the causes of roof rot can help homeowner know when to contact experienced Toledo roofers and arrange for a prompt repair or roofing system replacement before the issues escalate.
Before a roof can start rotting, moisture has to get into the wood. Water can get into a roof through a variety of means. One of the most common ways that Ohio roofs experience water damage is in the aftermath of a severe weather event. Situations such as hailstorms, high winds and ice dams may all allow water to make its way into the roof decking, joists, rafters, trusses and beams. Severe weather systems may cause the shingles to become loose, uplifted or blown off. The winds may also knock off the flashing. Once this happens, an opening is created, and water can flow into it.
Another common cause of roof rot is poor maintenance. Failure to replace an aged roof may result in moisture getting into the wooden substructure.

Not cleaning out the rain gutters on a regular basis may result in drainage backups. The overflow of water will take the path of least resistance, which is often right into the roof's substructure.
Improper maintenance techniques can also cause water to get underneath the roof. Using a power washer to clean algae off asphalt shingles shoots water right into the roof decking. Walking on fragile slate or clay tiles can cause them to crack, allowing water to drain into the roof's interior.
Inattentive installation techniques may cause a roof to start rotting shortly after it is installed. A lack of a moisture barrier or putting a roof on during rain or high humidity levels keeps moisture trapped inside where it weakens the wood. Using the incorrect type of roofing nails to attach the shingles or tiles is another issue that allows moisture in, which may lead to rot.
Flashing problems around the intersection of the roof and a chimney or vent may cause rotting of the wooden roof decking. The flashing may become loose or fall off after years of exposure to the elements. This gives water a chance to flow right into the roof.
