At MS Premier Roofing & Remodel, we pride ourselves on delivering top-tier roofing solutions tailored to protect your home and ensure peace of mind.
One unique aspect of how we approach roof replacements is our commitment to inspecting the roof decking during every project. While other contractors might overlook this crucial step, we believe that a solid foundation is non-negotiable when it comes to your roof's longevity and performance.
This blog will explore the importance of roof decking, why we thoroughly inspect it, and how this additional care benefits homeowners.
If you’re considering a roof replacement, here’s why starting from the decking up is the key to long-lasting results.
What Is Roof Decking?
Roof decking, also known as sheathing, is the structural foundation that supports your roof. It’s the layer of material secured to the trusses or rafters of your home, providing a base for the underlayment and shingles or other roofing materials.
Without proper decking, your roof’s integrity is compromised, no matter how high-quality the outer materials are.
Common Roof Decking Materials
Most homes use one of the following for decking:
Plywood: A reliable option that offers strength and durability.
OSB (Oriented Strand Board): A cost-effective choice made of pressed wood chips and resin.
Both materials can perform well when properly installed and maintained. However, over time, exposure to moisture, pests, and wear can weaken the decking and pose risks for your roof.
That’s why decking inspection is a critical element of every roof replacement we undertake.
Why Inspect the Decking?
Your roof decking may not be visible from the outside, but it plays a vital role in roof stability and performance. Here’s why we take a close look at it during every replacement:
1. Water Damage: Leaks or poor ventilation can cause water to seep into the decking, leading to swelling, warping, or rot. Damaged decking can fail to hold nails securely, compromising the roof’s overall structure.
2. Rot and Mold: If decking material sits damp for too long, it may develop rot or mold. Both issues not only weaken the structure but also create health hazards for those living in the home.
3. Structural Integrity: Your roof depends on its decking to withstand weather elements like wind, rain, and snow. If the decking is weak or damaged, the entire roofing system becomes susceptible to failure, even with brand-new shingles on top.
These potential issues make inspecting the decking a crucial part of every roof replacement. Finding and addressing problems early prevents larger, more expensive repairs down the line.
The MS Premier Roofing & Remodel Approach
At MS Premier Roofing & Remodel, we don’t cut corners. Our comprehensive roofing process includes careful attention to the decking, ensuring that every roof we install is built to last. Here’s how we do it:
Step 1. Careful Removal of Old Roofing: We begin by stripping away old shingles, underlayment, and other materials to expose the decking. This gives us a clear view of the foundation so we can identify any issues.
Step 2. Thorough Decking Inspection: Our team examines the decking for any signs of water damage, mold, rot, or other structural concerns. For full transparency, we document everything with photos and videos, so you can see for yourself exactly what we find.
Step 3. Proactive Recommendations: If we discover any issues, we’ll discuss repair or replacement options with you in detail. Our team ensures that you understand why certain actions are necessary and how they will enhance your roof's durability.
Step 4. Building a Strong Foundation: Once any necessary repairs or replacements are completed, we install new underlayment and shingles on a clean, solid decking base. This meticulous process sets your roof up for long-term success.
Decking Repair vs. Replacement
How do we decide if your roof decking needs repair or a full replacement? Here are the factors we consider:
When Repairs Are Enough
Minor water stains with no signs of warping
Small spots of localized damage that don’t affect the overall integrity
When Replacement Is Necessary
Visibly sagging sections of decking
Plywood or OSB that has warped, swollen, or deteriorated
Large areas of rot or mold
Decking that’s too thin or brittle to support modern roofing materials
Replacing damaged or subpar decking might feel like an added expense during your roofing project, but it’s one worth making. Neglecting structural issues at this stage can lead to costly problems in the future.
Benefits for Homeowners
Our thorough decking inspection and repair process isn’t just about what’s good for the roof; it’s also about delivering maximum value to homeowners. Here’s what you gain:
1. A Roof Built to Last: Starting with sound decking means your roof will withstand harsh weather conditions and daily wear much better, extending its lifespan.
2. Prevention of Future Issues: By addressing structural problems early, we prevent leaks, mold, and other issues that could otherwise lead to major repairs later.
