When it comes to replacing your roof shingles, it’s not just about the surface layer—what’s underneath matters just as much. Many homeowners overlook the importance of a solid decking base and quality underlayment like DeckDefense when planning a shingle replacement. These components are critical to the durability and longevity of your roof.
At Roof Repairs CA, we ensure every shingle replacement is supported by structurally sound decking boards and reinforced with DeckDefense underlayment. This combination offers superior protection, better performance, and long-term peace of mind for your home.
What Is DeckDefense and Why It Matters
DeckDefense is a high-performance roofing underlayment that adds a secondary layer of protection between your shingles and the decking. At Roof Repairs CA, we apply DeckDefense to every new shingle installation to shield your home from moisture, wind, and ice.
This synthetic barrier is stronger and more tear-resistant than traditional felt, helping to prevent leaks even if shingles are blown off during a storm. It’s a smart investment that extends your roof's lifespan and protects your home.

Why You Should Replace Decking with Shingles
You might not see your roof decking, but it plays a huge role in your roof’s integrity. Installing new shingles on old, compromised decking shortens your roof’s lifespan and increases the risk of leaks. During every shingle replacement, Roof Repairs CA inspects your decking for rot, water damage, and weak spots.
Replacing damaged decking at the same time as shingles avoids costly fixes down the road and ensures that your new roof performs at its best from day one.
