Beneath the shingles and tiles lies a series of wooden boards that reinforce the structural integrity of the roofing system. Unfortunately, roof damage may affect the roof decking, slowly compromising the entire structure. So, should you replace the decking during your upcoming roof replacement? Your roofer will help you determine whether replacing it is necessary. However, the following are signs that you need a new roof decking.
1. Unusual Bulges on the Inner Side of Your Roof
During a roof inspection, your roofer might discover that your sheathing is bulging in various spots. Excess moisture due to missing shingles or punctures may cause the sheathing to bow out. The extra weight put on the decking can be dangerous. The roof could cave in, putting you and your loved ones at risk. Your roofer may recommend replacing the decking during the roof replacement to provide a solid foundation for the new roofing materials.
2. Noticeable Damage
Have you noticed light penetrating through the roof into your attic? This indicates that your decking may be damaged. The punctures and holes typically develop due to storm damage. Depending on the extent of damage, your roofer might recommend replacing the entire roofing system, including the decking. This should minimize the risks of water infiltration into your home.
3. Mold Growth and Severe Rot
When it is time to replace your roof, there are generally two options. You could choose a full replacement or a reroof where the experts nail new shingles over the existing ones. The latter is only viable if the materials, including the sheathing, are in fairly good condition. Your contractor will first inspect your decking for signs of damage. Rotten wood boards or mold growth in the attic shows that the structural integrity of the decking has been compromised. Besides, leaving mold unaddressed only buys it more time to continue spreading to other sections of your home.
4. High Energy Bills
Issues on your decking can affect your utility bills. If your sheathing has holes and punctures, they contribute to heat loss. This might strain your heating system since it becomes harder to maintain the ideal indoor temperatures. As your system works harder, your home's energy consumption increases. Therefore, you should replace the entire roofing system to improve your home's energy efficiency.
Your roof decking is one of the most crucial sections of a roofing system. Watch out for the signs above to determine whether you need to replace the entire roofing system. Remember to work with a local roofing contractor to plan and implement the project.
