5 Signs You Need To Replace Your Roof Decking

From the underlayment to the flashing, each component in a roofing system plays a vital role in ensuring a roof's longevity and functionality. One of the most important components of a roof is the decking. Roof decking is a crucial part of the roof that lays the foundation for the other materials to be installed. 

Like any part of a house, roof decks have a limited lifespan and may call for replacement at some point. In this article, we’ll delve into five signs your roof decking may need to be replaced.

What Are The Signs Your Roof Decking Needs Replacement? 

Now that you know what a roof deck is, it’s time to move to the core of our blog post. Over time the weather conditions in Pittsburgh can damage your decking. Since the deck is the innermost layer of your roofing system, it can be difficult to judge the level of damage associated with it. That’s why to help you, we’ve listed some of the signs of damage you should look out for.  

Water Damage 

Water Damage 

Water damage is one of the most common reasons you might need a roof decking replacement. As water starts to seep in through your shingles to your deck below, it will cause several issues, such as rotting, warping, and weakening of the roof decking, compromising the structural integrity of the entire roofing system. If left untreated, the water damage will lead to further problems.

It's important to keep an eye out for signs of water damage in your roof decking. Visible water stains on your ceiling or interior walls clearly indicate a leak in your roofing system. If you notice any discoloration or peeling paint or wallpaper in your home, it's a good idea to investigate and find the source of the water damage as soon as possible.

Hole In The Roof

Holes in the roof are a serious issue that requires immediate attention. Holes can compromise the roof's structural integrity and allow water to penetrate the underlying layers of the roofing system to a point where your roof decking can become damaged. 

If you notice any holes in your roof, it's essential to contact a professional roofer right away to assess the damage and determine the best course of action. In some cases, small holes can be repaired with patches or sealant, but more extensive damage may require an entire replacement of the affected portion.


The effects of age and wear can compromise the integrity of roof decking, leading to leaks, mold growth, and other problems. It's essential to monitor the condition of your roof decking over time and to have it replaced when necessary to ensure your home's continual safety and protection. 

Regular maintenance and inspections help catch signs of wear and age early on, allowing for prompt repair or replacement.  

Worn Out Shingles

Having worn-out shingles is one of the most common signs that your roof decking is damaged. Shingles are designed to protect the underlying roofing materials from the elements and provide a barrier against water and moisture. Over time, however, shingles become worn or damaged, allowing water to penetrate the roofing system and cause damage to the roof deck.

Signs of shingle wear and tear include cracking, curling, granule loss, and missing shingles. If you notice any of these signs, it's essential to have your roof inspected.

Your Roof Is Sagging 

A sagging roof is a huge sign that there’s a problem with your roof and roof decking.  This problem occurs when the roof decking becomes weakened or damaged, causing it to buckle or bend under the weight of the roofing materials. A sagging roof is a serious issue that requires immediate attention, as it can lead to more significant problems like leaks, mold growth, and even roof collapse.

When a roof sags, it is usually not noticeable at first, but the longer you ignore the signs, the more this problem will grow and harm your property. 

A variety of factors can cause a sagging or bending roof. Here are some signs that your roof is sagging: 

  • Cracks on the exterior wall
  • Dips in the ridgeline
  • Dips along the entire roof

You Notice A Sudden Increase In Your Utility Bills

Most homeowners are generally aware of the importance of the roof deck when it comes to the overall health of their roofing system. But you may not know that the sheathing or deck of your roof also plays a role in your home's energy savings.  

A roof's primary function is to protect your home's interior from the harsh forces of nature, but a properly installed roofing system can offer you much more in terms of benefits, including a reduction in your monthly bills. Though there are several reasons for it, if you notice an unusual increase in the energy needs of your home, then the problem could be with your roof or the roof's decking. 

This can happen when roof decking is damaged or worn out, causing it to become less effective at insulating your home. As a result, your HVAC system has to work harder to maintain a comfortable temperature, leading to higher energy bills.

If you notice an unexplained increase in your energy bills, having your roof decking inspected by a professional roofing contractor is worth it. 

How Much Does It Cost To Replace Roof Decking? 

Replace Roof Decking

Now that you know when you need to replace your roof deck, the next thing you are likely to focus on is the cost of the roof decking. There are several types of roof decks available and the price will vary for each of them. 

Generally, the cost of decking material varies from $18 to $40 per square foot. However, a lot can influence the final price you’ll pay. Such as the following: 

  • The size of your roof 
  • The type of decking material used 
  • The pitch of the roof 
  • The area you live in 

How Do You Maintain Roof Decking?

Maintaining your roof decking is essential to ensure your home's continual safety and protection. Here are some tips on how to do that and ensure that your roof lasts longer without needing a total replacement. 

Regular Roof Inspections:

Inspecting a roof is a task that does not require much effort or money but can do wonders for the longevity of your roof. Schedule regular inspections of your shingles, preferably twice a year, to identify any signs of damage, wear, or aging. Inspections can help catch potential problems early on and prevent costly repairs down the line.

Keep Your Roof Clean

One of the ways in which your deck can become damaged is when your roof retains moisture. One way to avoid this is by cleaning your roof from time to time. Keep your roof decking free of debris, such as leaves, branches, and dirt, as this can trap moisture and cause damage to your property. Regular cleaning will help prevent debris buildup and promote better drainage.

Replace Damaged Or Worn Components:

Replacing damaged or worn components are important to maintaining your roof decking. If you notice any signs of damage, wear, or aging, addressing these issues promptly is crucial to prevent further damage and protect your home. Some signs that components of your roof decking may need to be replaced include cracked or warped boards, missing shingles, or visible signs of rot or decay.
