Dry rot isn't really dry, but it will certainly destroy a roof. Dry rot is caused by two types of fungi, and both are moisture loving. In areas of high moisture, such as a roof, these fungi will invade and feed on the wood, digesting the wood fibers until the wood breaks down. The wood shrinks and becomes brittle and crumbly.

Dry rot can be identified by large patches of discolored wood that is cracked or split open in many places. Wood afflicted with dry rot is very soft and can be pulled apart by hand or easily punctured with the tip of a screwdriver. Infected wood also exudes a musty smell characteristic of dry rot.

Dallas homeowners who suspect that dry rot has damaged their roof should contact a Dallas roofing professional without delay. Dry rot can severely weaken the integrity of a roof, which could pose a threat to the safety of a homeowner and his or her family.

A roofing professional can perform a thorough inspection of the roof and offer an expert opinion on needed repairs. A cost estimate can also be calculated.

In high humidity areas like Dallas, roofs should be inspected for dry rot once a year.

If a roof was poorly constructed or is old and leaky, dry rot is likely to be present. Also, a roof damaged by storms or hail and not repaired in a timely manner can become a prime candidate for dry rot.

Repairing a leaky roof or replacing a poorly constructed or old roof can eliminate the cause of dry rot. However, if only portions of the roof are replaced, wood treated to resist the dry rot fungus should be used in the new roof construction.

Proper ventilation is the key to preventing the high moisture that causes dry rot in an attic and the underside of a roof. In areas of high humidity, dry rot can form under worn or damaged shingles on a roof. The ravenous fungus will spread and eat through the plywood roof decking, causing the roof to weaken and eventually cave in.

Homeowners should watch for any areas of their roofs that might appear sunken or irregular. A sunken spot means the wood decking has collapsed from dry rot under the underlayment and shingles. Any such sunken spots should be repaired immediately before the fungus spreads even further and does more damage to the roof and attic rafters.
