A unique problem that can affect many types of roofing is dry rot, a destructive process that can result in a homeowner needing to replace their entire roof.
Dry rot is the slow deterioration of the roofing material and support structures that happens over time, culminating when an affected roof can no longer remain watertight and the roof structure begins to rot.
Fortunately, homeowners can work with a roofing service to prevent this costly problem and keep their installation in great condition for its full life expectancy.
What Exactly Is Roofing Dry Rot?
The first step to preventing roofing dry rot, also called roof rot, is understanding what it is and how it happens.
According to roofers, dry rot is caused by fungal growth that spreads under the external roofing materials.
It starts on roofs that remain moist, usually due to poor attic ventilation that causes the roof to overheat.
It can also happen anywhere that moisture reaches the roof underlayment and decking, such as loose roof flashing or pipe boots, roof edges that get submerged in clogged overflowing gutters, and anywhere there is a leak.
How Does Dry Rot Spread?
As moisture gets absorbed by the underlayment and then the wood decking as well as other wood components and remains damp and moist, fungal growth begins.
Over time as the fungus quickly spreads, the integrity of the roofing materials decreases as moisture and fungal growth increase.
Eventually, affected decking and support structures will start to fail, sometimes to the point of the roof sagging or collapsing.
How Can Dry Rot Be Prevented in Roofs?
How can homeowners prevent dry rot from affecting their roofing installation?
The most important action that homeowners can take to protect their roofing from a serious problem like dry rot is to arrange for regular inspections from a reliable local roofing service.
A knowledgeable roofer will test for adequate attic ventilation to ensure there is no overheating, plus inspect all the common areas where problems like roof rot can occur.
Should there be any leaks or other water damage that could result in fungal growth starting, have the roofer repair it right away.
Then just keep up with roofing maintenance and periodic inspections.
