Roofer Royal Oak MI

When you have an roofing inspector look at your roof there are several parts they need to check for problems. One of these parts that is crucial to check is the sheathing or sometimes called the roof decking. The sheathing is  made of wood decking and panels that provides the base layer for all the other layers of your roof to be placed on. Because it is under the shingles or metal sheeting it is often overlooked, but a proper inspection needs to focus on the sheathing just as much as the top layers. This is because no matter how good the condition of the top layers are, once the base goes it affects the entire roof. Having a roofer in Royal Oak Michigan inspect your home’s roof sheathing can give you a much better idea of how well the roof is performing and if there are any problems you should be concerned about.

The different types of construction has changed how roof sheathing is done. Homes that are more than 30 years old likely have deck boards that are installed on the roof. These are usually pine boards that are one inch thick and about six inches wide. These boards are placed on the roof and connected to the truss using nails. More modern roofs use larger sheets of wood which can be OSB or plywood. Both of which are four feet by eight feet. This helps create a more streamlined roof and it’s faster to install. In either case, when there is a problem on your home’s roof you’ll need the roof sheathing inspected.

When an roofer in Royal Oak Michigan does their inspection on the sheathing there are certain things they are looking for. This involves looking under the shingles or sheeting and going into the attic and looking at the inside of the roof.

Some of the red flags the inspector will be looking for include:

Drooping:

To function properly and support the top layers of your roof, the sheathing must keep it’s structural integrity. When the sheathing starts to droop, sag or warp in any way it is a good sign that the structural integrity is now compromised. If you catch it early on the sheathing can be repaired. But if the problem goes undetected and is allowed to get worse you are looking at a replacement to be able to regain your roof’s structural integrity. Single squares and sections are able to be fixed with blocking to secure that section, but it is important to keep a close eye on it to make sure the problem isn’t getting worse over time.

Moisture:

The shingles and sheeting should prevent any moisture from getting past it and into the sheathing. So if the sheathing feels moist there is a problem not only with the exterior of the roof, but the sheathing will need to be replaced to prevent warping, dipping and mold.

Mold:

Mold is an immediate threat not only to your roof’s sheathing, but the entire home. Mold spreads quickly when conditions are right and it is almost impossible to completely get all of the mold out of wood. If the sheathing on your roof shows signs of mold you will first need to identify where the problem is coming from and them replace the sheathing boards. Mold in the sheathing is typically from either moisture getting through or poor ventilation in the attic. Do not replace the sheathing until you have identified and remedied the problem or you will end up in the same position you where just in.

Sunlight:

Much like moisture, the top layers of your roof should prevent any light from getting through to the sheathing. When you look at the sheathing and you are able to see light coming through it points to a big problem. Not only is it an access point for water, pests and overall is not a good thing to have, but the light coming through can mean replacing the top and sheathing layer depending on how bad the problem is.
