Roofs are known to be rather complex and that’s why it’s essential to be familiar with their layers and components. This includes your roof decking. It is known to be the layer of materials found over the rafters and below the felt underlayment beneath your shingles.

Roof Underlayment

While being flexible enough to give slightly in warm and high winds and under load, your roof decks must be strong enough to bear the weight of the roofing shingles. This feature is often built by a roofer with plywood or an oriented strand board. It may also be constructed of boards that are connected with a tongue-and-groove joint.

Residential roofing experts note that the deck is considered the base of your roofing system and what binds all of its parts together. With a good foundation, your roof will perform better and last longer. Shingles can weigh hundreds of pounds per square.

Other options like slate and tiles are even heavier than asphalt shingles. This means that the deck should be strong enough to handle whatever roofing material you will choose for your home. Moreover, it is expected to be equipped in helping moderate moisture levels at home by keeping rain and the snow out and allowing excess moisture to evaporate through the attic. 

How do you know if your roof deck or sheathing has damage?

Most roof repair pros may suggest that the signs may or may not be obvious however, these are some of the hints that may be easily seen:

  1. Missing shingles. Roof decking can develop damage in areas of the roof where there are missing or damaged shingles due to weather extreme conditions and aging. Roofing systems normally last for at least 20 years, depending on the material, installation, and climate. If this part of your home is at least two decades old, it may be time to consider getting a roof replacement.

  2. Visible sagging of the roof. Residential and commercial roofing installers suggest that if your roofline is sagging, it could be that your deck has severe damage, making problems with the structure of your roof. Once water soaks the decking, warping can occur, causing the roofline and ceiling to bow and sag.

  3. Mold and mildew. Remember that constant exposure to water can cause the wooden components of your roof, such as the deck, to rot. Water can penetrate the roof through damaged or clogged gutters and damaged flashing. Deteriorating shingles and excessive snow during winter can cause water to enter your roof. 

What are the common causes of roof decking damage?

  • Poor Ventilation

Both residential and commercial roofing systems need good ventilation for optimal performance and longevity. With sufficient ventilation, excess heat and moisture can escape your attic and home. No matter the climate of your area, having an underventilated attic can have serious consequences. 

Poor ventilation causes your attic to become extremely hot, resulting in the deterioration of the decking and shingles. The heat may transfer to your living spaces as well, causing discomfort, increasing your energy costs because your HVAC would need to work harder than usual. During colder seasons, meanwhile, poor attic ventilation can contribute to the formation of ice dams. Once the melted snow reaches the edges of your roof, it will refreeze and form ice dams. Ice dams can cause water to penetrate your roof and cause moisture-related issues, such as rot to the decking. 

  • Faulty Solar Panel Installation

Improper solar panel installation can also be an issue. Although adding solar panels to your home is a great way to reduce your energy costs, its placement must be done properly to avoid roof issues. Before getting them, it’s best to consult experts first to determine if your roof and home can handle their load. Also, only hire experienced professionals for their installation. 

  • Rot Due to Excessive Water

Great and constant exposure to water can cause the wooden components of your roof, such as the deck, to rot. Water can penetrate the roof through damaged or clogged gutters and damaged flashing. Deteriorating shingles and excessive snow during winter can cause water to enter your roof. 

Can you have your decking repaired?

As it’s iterated that only trained and professional roof repair contractors are advised to work on your decking, here are more of the reasons why doing DIY-ing decking repairs isn’t encouraged:

  • Once your roof deck has rotted, repairing it is no longer an option. Plus, repairs are always considered a temporary solution. Renewing the deck is the better solution. This prevents further damage to the system and ensures the roof materials can have a sturdier foundation.

  • There is little to no assurance that your roof decking won’t get damaged or broken again. Because the roof decking is typically made of wood or composite wood fibers, it can still be susceptible to moisture damage. Mold and mildew may eventually develop on the boards, leading to rot that weakens the support structure of your system. 

If it’s better to have your roofing replaced, for it to last longer, it needs to have a sturdy base for the shingles. Replacing shingles and the decking at the same time will give your home more protection against the elements. Moreover, you can help avoid damage to your roof deck with proper maintenance. Above all, scheduling regular roof inspections and maintenance would make a significant difference. Never take your gutters and have them routinely cleaned to prevent clogging due to debris buildup.

Also, homeowners are always urged to call a reliable roofer for maintenance, fixes, most especially, installations. Should your system has been damaged, it’s important to act immediately so you won’t have to deal with costly repairs in the future.
