However, one crucial aspect that often gets overlooked during the purchasing phase is the substrate for asphalt shingles. Choosing the right substrate can significantly impact the performance and longevity of your roof.

The substrate serves as the base layer on which asphalt shingles are laid. It influences factors like the roof's strength, moisture resistance, and insulation quality. Common substrates include plywood, oriented strand board (OSB), and concrete. Each type has its pros and cons, which can raise questions for homeowners. Let’s explore some common concerns and solutions.
Many customers worry whether their chosen substrate will withstand extreme weather conditions, like heavy snowfall or strong winds. For example, plywood is known for its strength and can generally handle higher loads than OSB, making it a preferred choice in regions prone to harsh weather. However, if you live in a milder climate, OSB might suffice and can save you up to 20% in material costs.
Real-World Example: A customer in New York opted for 5/8-inch plywood after researching the challenges of heavy snowfall in the area. After several winters, they noted no sagging or leaks, confirming that their choice was beneficial.
Another significant concern is moisture resistance. Excess moisture can lead to mold growth and structural damage. Plywood offers better moisture resistance than OSB due to its natural properties, but it is essential to ensure that any substrate you choose is treated for additional protection.
Customer Case Study: A homeowner in Florida chose treated OSB for its lower cost compared to treated plywood. After two years, they experienced minor mold issues. Upon reviewing the products, they realized a more moisture-resistant option could have prevented the problem, leading them to upgrade during their roof replacement.
How easy a substrate is to install can greatly affect overall project costs. Both OSB and plywood can be installed by most roofing contractors, but OSB is typically lighter, making it easier to handle and install. This can reduce labor costs by up to 15%.
Homeowners should also consider the weight on their structure; installing heavy materials might require additional reinforcements, adding to the expense.
Example Insight: A customer in Texas shared that using lighter OSB reduced installation time by two hours, ultimately saving them $200 in labor costs.
Cost is often a primary concern when selecting a substrate. Here's a quick breakdown of average costs:
While your initial inclination may be to save money on the substrate, consider your local climate, design, and long-term maintenance costs. The cheapest option upfront might not always be the best choice for a durable roof.
Selecting the right substrate for asphalt shingles is key to ensuring your roof's longevity and performance. Take into account factors like durability, moisture resistance, ease of installation, and costs. Consulting with a trusted roofing contractor can also provide personalized insight based on your specific needs and location.
Before making your decision, compile questions you have regarding each substrate option, and don’t hesitate to ask your contractor for clarity. Knowing what to ask will help you make an informed choice and prevent future headaches.
