New Roof in Progress in McCordsville, IN: Decking and Underlayment
Austin Chastain : Nov 11, 2026, 4:22:41 PM
This week Blue Ladder Roofing is replacing the roof on a two-story home in McCordsville, IN. This is part 1 of the project, covering the parts of a roof you never see once the job is done but that matter most: the decking and the underlayment.
Tear-Off Comes First
We remove the old shingles and underlayment completely instead of layering new shingles over old ones. A full tear-off lets us inspect the wood deck, find hidden damage and give the new roof a flat, solid surface to sit on.
Why Deck Repair Matters
Roof decking (the plywood or OSB under your shingles) can soften or rot after years of small leaks, poor ventilation or storm damage. Shingles nailed over a soft deck won't hold properly and can fail early. When we find bad sections, we cut them out and replace them with new boards instead of covering them up.
What Synthetic Underlayment Does
Once the deck is solid, we cover it with synthetic underlayment. It's a tough, water-resistant layer that sits between the deck and the shingles. Compared with old-style felt paper, synthetic underlayment resists tearing, lies flatter and keeps the deck protected if a shingle is ever damaged or blown off.
Coming Up in Part 2
Next up are the new shingles, flashing and ridge ventilation. We'll share finished photos once the roof is complete.
