How To Deal With Wood Rot On Your Roof

A common problem with neglected roofs is wood rot. The wood parts of your roof can slowly rot over time. If the condition is caught early, repairs can be done while the damage is minor. When the rot is extensive, the structure of your home could be in danger, and your roof may need to be replaced rather than repaired. Serious wood rot problems can often be avoided by having your roof checked regularly so problems can be caught early. Here are some tips for dealing with roof rot.

Ensure Your Attic Has Enough Ventilation

Asphalt roofing systems need adequate ventilation to prevent problems with moisture, heat, and wood rot. A residential roofing contractor can calculate the amount of ventilation needed based on the square footage of the attic. The roofer may add more vents if needed to increase ventilation, or they may need to unblock vents already present. By making sure your attic is properly ventilated, the risk of wood rot is decreased and your shingles may even have a longer life.

Uncover The Reason For Wood Rot

A residential roofing system has a layer of shingles on top and underlayment between the shingles and deck. When these parts are all in good shape, the wood part of your deck stays dry. If your deck develops wood rot, the roofer needs to figure out why so the cause of the problem can be eliminated when the rotted wood is replaced.

Possible causes besides poor attic ventilation include a roof leak and clogged gutters. Rain needs to drain away from the roof so the roof stays dry. Anything that stays on the shingles such as damp leaf clumps in roof valleys or moss growing on shingles can also contribute to roof rot.

Remove Rotted Wood

The repairs your roofer does may depend on how the problem has affected your roof. The roofer will probably check the underside of the roof from your attic as well as the surface of your roof. Rot could be widespread in your attic or mainly confined to the deck on top of the roof.

In some cases, the roofer might repair rotted wood, but generally, the rotted wood is removed and replaced with strong, dry materials. The deck of the roof and the fascia boards are two areas commonly affected by wood rot. Gutters need to be removed to replace a rotted fascia board, and once the new board is in place, the gutters can be replaced.

When the wood deck is rotted, the shingles and underlayment need to be removed so the roofer can cut out the rotten deck. New underlayment and shingles are then installed once the new deck is in place. This may require careful work since a rotted deck could collapse when the roofer walks on it.

Inspect The Roof Regularly

Check your roof from inside your attic a few times a year and have a roofer check the surface of your roof periodically. Since wood rot develops slowly, you have plenty of time to catch the problem and have repairs done before the rot has caused a lot of damage to your home.
