Blog Banner 3 (3)

Rotted wood is a problem. The decking underneath your shingles on your roof is made of plywood. It is sometimes called sheathing because the thin sheets of wood are laid out over the frame of your home, or the joists. If exposed to water frequently, the sheathing can start to rot and create a leak in your roof.

A leak in your home can cause all sorts of problems. Not only can a leak damage your personal items, it can damage the structural integrity of your home and your electrical system. The electrical system or water damage to walls and ceilings can be very expensive to fix. If you regularly inspect your home and your roof for possible leaks and damage, you’ll be better able to identify when your roof needs repairs.

You’ll be able to notice the signs of moisture getting in your roof and you’ll be able to have an inspection done right away. That could save you time and money down the road.

What Are the Signs You May Need a Professional Inspection for Your Roof?

If moisture gets to the wood in your roof, it will cause decay over time. Moisture will also cause a fungus to grow in the wood and that can cause problems for your roof and your home. The most common issues from roof rot are swelling of the shingles, mold, and damage to insulation and other functions of your home.

Bowing or Bulging of the Shingles

Moisture and wood rot can cause swelling in your decking. This will look like a spot that is bulging on your roof. If this happens, the shingles will not be lined up in a way to protect more water from getting into your home. Eventually, after repeatedly being exposed to moisture, your decking could rot completely and fall apart.

Fungal and Mold Growth

Wood rot can lead to the growth of mold or other fungi. If mold gets in your home, it can cause illnesses and make respiratory conditions worsen. For the health of yourself and your family, check to make sure the wood in your attic is dry and secure.

Damage to Functions in Your Home

There are important areas of your home that if exposed to moisture can reduce the efficiency and structure of your home. The things to look out for are damage to insulation, wood, and home systems like electrical wiring. There is insulation right below your decking and if moisture damages the decking and insulation it can cost you more money to cool your home.

Dry rot is a type of wood rot and it can spread to other healthy wood in your home. Dry rot will look discolored and patchy and it will be soft to the touch. If you do find dry rot it is best to fix it right away because replacing more of the structure will be expensive.
