Steep Gables, Plank Decking and Multiple Shingle Layers
Tear-offs on these houses often uncover two or three shingle layers, sometimes with cedar underneath. Below that is usually board decking with gaps, split boards and old nail holes that will not hold a modern shingle nail.
Because nobody can count rotten boards from the ground, our written quotes carry a per-sheet price for new plywood. After tear-off we photograph the deck, agree on the sheet count with you and bill only what was installed.
Some century roofs also sag at the ridge or between rafters spaced wider than today's standard. In those cases we recommend structural reinforcement, such as sistering rafters or adding collar ties, before new shingles go on.
