🔨 This is the part of a roof replacement most homeowners never get to see, but it makes a huge difference.
For this Alexandria project, the original roof decking was upgraded with new plywood sheathing to create a stronger, more uniform surface beneath the new roofing system.
The inspection phase revealed that the older plank decking was in poor condition and could affect long-term fastening performance, so a full plywood overlay was the right solution before installing the new Owens Corning Duration roof in Peppercorn.
We also installed H-clips between trusses to help improve support and stability across the roof deck.
A roof is only as strong as the surface beneath it, and this upgrade helps set the foundation for a longer-lasting roofing system built to modern installation standards.
