A roof replacement timeline should tell you when to move the cars, when someone needs to be reachable, and what happens if the forecast changes. Grand Rapids had five dry days from September 25 through 29, followed by 0.38 inch of rain on the 30th. For a fall installation in Holland or Grand Haven, the difference between those two kinds of days matters most once the old shingles come off.
Before the truck arrives
Confirm the material delivery and where the dumpster will sit. Move vehicles you need for work or school before the driveway is blocked. Point out irrigation heads, fragile plants and the gate the crew should use. If the garage is detached, confirm whether it is in the scope and whether you will still have a clear route between the house and the street.
Get the name and number of the person who can answer questions during tear-off. Ask how they will send decking photos and how long you have to approve a change. If the cost of extra decking is unclear, our guide to comparing roof replacement estimates shows which numbers to settle before installation day.
Build a rain decision into the roof replacement timeline
Ask who checks the short-range forecast before opening a slope and how much roof the crew expects to expose at once. If the weather turns, what materials are on hand to protect the open area? Ask what the crew means by “dried in” and what still has to be installed before the roof is finished.
Temperature also matters. Ask how the installer follows the chosen shingle manufacturer’s cold-weather fastening and sealing instructions. A sunny afternoon and a cold shaded slope can give the crew different working conditions on the same house.
Walk the property before the dumpster leaves
Ask for photos of the decking repairs and flashing that are now hidden. From the ground, check that gutters and outlets are clear and that the crew has swept the driveway and paths for fasteners. Get the product name, warranty documents and a contact for follow-up. For a proposed start window and a written scope of work, arrange a residential roof inspection before you book time off or move vehicles.
