Tear-Off Vibration Can Shake Your Wall Art Loose

Tear-off day is louder inside the house than most homeowners expect. A pry bar working under old shingles, a flat bar lifting nails out of the deck, and a dumpster bin set down against the driveway all send a shock through the framing. That shock travels along the ceiling joists and into the wall studs, and the first things to move are the things hung on nails and small screws: picture frames, mirrors, a wall clock, and the glass shelf above a bathroom sink. Nothing dramatic has to happen for a frame to end up crooked or a cabinet door to swing open on its own.

This is a small line in a roof bid, but it is one you can compare directly. Two roofers can quote the same square count and the same shingles and still have very different plans for the rooms directly under the work. One may say the crew will be careful. Another will say which rooms get cleared, which walls get padded, and who moves the furniture. Only the second answer gives you something you can check on the day.

Why the walls move on tear-off day

A roof deck is a rigid surface, and the crew pushes and pulls on it all morning. Every nail that comes out makes a sharp crack that the wood carries down to the rafters. In an older Chesterfield house with plaster and lath, the ceilings can flex more than a newer drywall ceiling, and that flex shows up as dust falling from light fixture housings and hairline cracks opening at the corners of doorways. In a newer house with drywall, the usual result is a loose frame or a rattling window that was already sitting a little off its track.

Freeze and thaw cycles make this worse in the St. Louis area. A wall that has been through several winters of expansion and contraction may already have a crack that you have stopped noticing. The vibration from a tear-off does not create that crack, but it can widen it, which is why a before-and-after record of the walls matters. Ask each roofer whether they photograph the interior walls and ceilings before the first nail comes out. A roofer who takes photos of your house before starting is doing the same work as a roofer who photographs the roof, and you should expect both.

Hail season adds another layer. If your roof is being replaced after a storm, the interior may already have some staining or a weak spot in a ceiling from earlier water. The crew should not be asked to repair that, but you should know where it is before they arrive, so the record is accurate on both sides.

Roofer comparison

When you lay two bids next to each other, look for the interior protection language, not just the word clean-up. A few questions will show you which roofers have thought about the rooms below and which ones have not.

• Who clears the rooms: Does the bid say the crew moves furniture, or does it say the homeowner must clear the walls before the start date? Both can be reasonable, but the bid should say which one applies.
• What gets removed from the walls: Some roofers take down the frames and mirrors above beds and sinks. Others cover them in place with blankets. Either approach should be named in the scope.
• Where the crew works from inside: If someone needs to go into the attic, check whether the bid includes a walk through the attic hatch and whether that crew member is careful with the ceiling below.
• Before and after photos: A written scope that promises photos of the interior walls before and after the tear-off is more useful than a general promise to be careful.
• Who fixes a nail hole or a dislodged fixture: The bid should say whether the roofer is responsible for re-hanging a fixture they dislodged, or whether the homeowner is expected to do that work.

Keys Roofing documents damage and puts a written scope with photos and measurements in the homeowner's hands before the work begins. That record covers the roof, and it can cover the interior rooms the same way when the homeowner asks for it. If a bid says nothing about the rooms below, ask the roofer to write the interior step into the scope before you sign.

What it costs

Protecting the interior is usually a labor item inside the roof bid, not a separate charge. Moving furniture, covering walls, and photographing rooms take crew time, and that time should show up somewhere in the price. If one bid is lower and says nothing about the interior, the difference may be that the protection work is missing rather than that the roofer is cheaper. Ask each roofer to point to the line where the interior work sits, so you can compare the two bids on the same terms.

Some homeowners choose to take down their own frames and shelves before the crew arrives. That can save money on the bid, but it moves the work to you and the timing to your schedule. If you choose that route, write down which items you removed and when, and keep the photos from that day with your roof file.

What to ask

1. Will you photograph the interior ceilings and walls of the rooms under the work before the first nail comes out, and will you send me those photos?
2. Which rooms will you clear, and which will I need to clear myself before the start date?
3. What will the crew do with the frames, mirrors and shelves on the walls that sit above the beds, sinks and stairs?
4. Who re-hangs a fixture or frame that comes loose during the tear-off, and is that written in the scope?
5. Where in the bid does the interior protection appear as a line or a named step?
6. If a hairline crack I have not noticed shows up after the tear-off, how will the crew record it on the day?

Send these questions in writing and compare the answers. A roofer who names the rooms, the items and the photos is describing the same job you are paying for. A roofer who only says the crew will be careful has not yet told you what the day looks like, and the page on the start date and the job-day contact sheet is a good next place to check how that roofer plans the rest of the schedule.
