How many layers are up there now?
Overlay costs less in one case only. There's a single existing layer, it's dry, and the deck under it is sound.
Two or more layers mean a full tear-off. That adds labor, debris removal and the container. It also opens the deck to us, so soft wood gets fixed, not buried.
Hidden under the old roof
Each of these gets a unit price in your written quote before we start. So the total never jumps without warning.
