Documenting decking rot before you cover it

The tear-off is halfway done and you find it: a soft spot over the garage, a sheet of decking that flexes under your boot and shows the black bloom of rot at the seam. You know what that means. That is not in the contract. The homeowner signed for a re-roof, not for framing repair, and now you have twenty minutes before the new deck goes down to turn what you found into money you can actually collect.

Most crews handle this backwards. They pull the bad sheet, cut in the new one, keep the line moving, and mention the extra to the homeowner at the end of the day or on the invoice. By then the decking is covered, the felt is on, the shingles are half laid, and the only evidence that the rot ever existed is your word against a memory. The homeowner is standing in their driveway trying to picture a piece of wood they never saw, and the number you are asking for feels like it came out of nowhere. This is the exact spot the proof and getting paid guides keep coming back to: the money is won or lost before the evidence gets covered up.

The window closes when the sheet goes on

Here is the part that matters, and it is easy to miss when you are moving fast on a tear-off. The decking change order is not won at the invoice. It is won or lost in the twenty minutes between finding the rot and covering it. Once the new sheet is down, the proof is gone forever. You cannot go back and photograph a subfloor you already replaced.

That gap is where the argument lives. You saw the rot. Your crew saw the rot. But the homeowner was at work, or inside, or looking at their phone, and three weeks later when the bill lands they are remembering a different conversation. They are not lying. They just never had the picture, so their memory filled the space with the version that costs them less. This is the same trap that catches you on any job where the truth gets buried by the next step, which is why the smart move is to photograph the condition before it gets covered by the next trade. On a roof, the next trade is your own second sheet of plywood.

The fix is not to argue better later. It is to make the record before the evidence disappears, and to get the homeowner to agree while the rot is still sitting there in the open where anyone can see it.

What a rot photo actually has to show

A photo of a dark stain on wood does not settle anything. An adjuster or a homeowner looking at it sees a shadow. A change-order photo has a job to do, and it needs three things in the frame to do it.

The framing member. Show where the rot sits in the structure: the rafter, the truss, the fascia line, the ridge. A close-up of rotten wood floating with no context could be from anyone’s roof. A shot that shows the bad decking sitting on a specific rafter over the garage is tied to this house, this slope, this spot.

The extent. One tight photo of the worst inch undersells a four-foot run, and one wide photo of the whole roof loses the damage entirely. Shoot both: a wide frame that shows how far the soft area runs, then the close-ups that show how bad it is. Two sheets replaced looks like two sheets replaced.

A tape measure in frame. This is the one crews skip, and it is the one that ends the argument. Lay a tape across the rot so the photo carries a number. Four feet of delaminated decking is a fact. “Some rot over the garage” is a feeling. The tape turns your finding into a measurement the homeowner cannot shrink later.

Take the shots before you pull a single bad sheet. The moment you cut it out, the best evidence you will ever have is a scrap in the dumpster.

The photo, then the yes, in that order

Photos alone do not get you paid. They prove the rot was real, but they do not prove the homeowner agreed to pay for it. You need both, and you need the agreement while the wood is still exposed. Here is the sequence that holds up.

Shoot the rot with the framing, the extent, and the tape, the way we just laid out. Then, before you cover anything, reach the homeowner with the picture and a plain number. Not a vague heads-up, a specific ask they can say yes to. The script is short:

“We are into the tear-off and found rotted decking over the garage, about four feet of it, soft enough that we cannot roof over it. I am sending you two photos. Replacing it is two sheets of plywood plus labor, ninety dollars in material and about an hour, call it two hundred and forty total. I need a yes before we cover it so nothing gets buried. Want me to proceed?”

That message does three things at once. It shows the proof, it puts the exact dollar figure in front of them before the work happens instead of after, and it asks a question with a one-word answer. When they reply “yes, go ahead,” you are done. The rot is documented, the price is agreed, and the approval is on the record before the first sheet went on. That is a verbal change order turned into a written one, which is the whole difference between a bill you can collect and a bill you have to fight for.

Put a number on the version that skips this

Say you skip it. You find four feet of rot, you replace it because you are not going to roof over garbage, and you plan to explain it later. The material is ninety dollars, the labor is an hour, the fair charge is two hundred and forty.

Three weeks later the invoice goes out and the homeowner calls. They do not remember agreeing to any decking work. There is no photo, no tape, no yes, just a line item. Now you have two bad options. You eat the two hundred and forty to keep the peace and the review clean, or you spend an hour on the phone arguing over wood that no longer exists and probably eat it anyway, plus the hour. Do that three or four times a season, because on a small roofing shop you will, and you have given away a thousand dollars and a full day of your own time defending work you actually did. The rot was real. You just had no way to prove it after you covered it.

The version that takes the photos and gets the yes costs you five minutes on the roof and collects every time. Same work, same wood, completely different outcome, and the only variable is whether you made the record before the sheet went down.

Where the photo and the yes live together

The reason this fails on a group text is that the photo and the approval end up in different places. The picture lands in the crew thread with fifty other images. The homeowner’s “yes, go ahead” is a text on your personal phone. Three weeks later, proving they belong to the same job, the same rot, the same conversation means scrolling two separate histories and hoping the timestamps line up.

Crewmigo keeps them together because the job is a thread of its own. The rot photos land on the decking task, the homeowner approves it right there, and the picture and the yes sit in the same place with the same job attached. When you sign off the roof, the record shows the proof and the approval next to each other, dated before the new deck went on. We are new, so put one roof on it: the next time you find rot, document it in the thread and see how the change-order conversation goes when the homeowner is looking at the same tape measure you are.
