Schedule roofing crews around weather by deciding the rules before the forecast changes: book each crew below full so the week has a float day, keep a list of weather-flexible work, and move only the jobs that have to move instead of sliding the whole board.
Every roofer knows the weather wins. What varies between companies is how much one lost day costs. On some boards a rain day is a crew-day lost and recovered by Friday. On others it starts a slide that touches every customer for two weeks. The difference is rarely the weather. It is the rules.
Why one rain day turns into a week
Picture a crew scheduling board booked solid. Crew A has a tear-off every day Monday through Friday. Tuesday rains out.
The default move is to slide. Tuesday's job goes to Wednesday, Wednesday's to Thursday, Thursday's to Friday, Friday's to next Monday. It feels like one change. It is four. Each moved job has a customer to call, a material drop that may already be on the driveway, a dumpster rental with dates, and sometimes a permit inspection booked against the old date.
Then it rains again next Tuesday, and the slide starts on top of the first one. That is how a 100%-booked board in a wet month ends up three weeks behind with every customer upset.
Rule 1: book below full
A board with no slack has nowhere to put a lost day except the next customer's slot. A board booked to four days of five has a float day already waiting.
Let C be crews, W working days per week, and R the rain days you expect per week in a given month, from your own records. If you book each crew for W − R days, rounded down, the expected rain fits inside the week instead of pushing into the next one. In a dry month, the float day becomes repairs, inspections, punch lists and warranty visits: work that can wait if the weather is good and fill a day when it isn't.
Use your own job history for R. Last year's lost days by month are better than any forecast for planning, and the forecast is better for the next five days.
Rule 2: decide the call time and the threshold
Most rain-day chaos comes from deciding at 6:30 a.m. with the crew already at the yard. Set two things in advance:
- The call time. For example, the go or no-go decision is made by 5:00 p.m. the day before, with a second check at 5:30 a.m. for borderline days.
- The threshold. What forecast, wind or temperature conditions mean a tear-off doesn't start. This depends on the materials, the roof and your own safety rules, so it is your decision and your manufacturer's, not a number to copy from a blog.
A clear rule means the crew lead, the office and the customer all hear the same answer at the same time.
Rule 3: move the minimum
When a day is lost, move only the job that lost the day, and put it in the float slot. Leave everyone else where they are. One customer gets one call.
If there is no float left that week, move the lost job to the next free slot rather than shoving every later job down. The customer at the back of the line is the only one who waits longer, and they may not wait at all if the first open slot is sooner than their original date.
Rule 4: have weather-flexible work ready
Not every rainy forecast is an all-day washout. A crew that can't start a tear-off may still do an interior attic inspection, a gutter job on a covered porch, a small repair once a morning shower passes, or a material pickup. Keep a short list of these, sorted by area, so the crew lead isn't calling the office to ask what to do.
Rule 5: re-check the drive after a reshuffle
When the week changes, the crew's path changes too. A crew that was going Monday north, Wednesday north, Friday south may now go north, south, north. Nobody checked those new drives. On crew work, every extra hour of driving is multiplied by headcount. The roofing scheduling page covers how estimator routes and crew days interact on the same board.
The reshuffle cost, in numbers
Here is the arithmetic for one rain day handled two ways. All figures are illustrative.
Let K be the office cost of moving one job (calls, delivery change, dumpster change), and J the number of jobs moved.
The crew-day is gone in both cases. What the float day saves is the cascade: three fewer moved jobs, three fewer customers on the phone, and three fewer delivery and dumpster changes. Track your own rescheduling rate by month and you'll see which months need more float.
The obvious objection is that a float day is a day you didn't sell. In a dry week it isn't empty: it is the repair and service work you would have squeezed in anyway. In a wet week it is the day that kept four customers on their original date.
Where software fits
Whatever you use, check two things. First, can the office see a crew's week and move one job without dragging the rest? Second, when the order changes, does anyone see the new drive? Roofing-specific CRMs and production tools handle a lot of the paperwork around this. The CrewLink vs AccuLynx comparison sets out where a roofing platform fits and where a scheduling layer fits.
CrewLink's dispatch board shows month, week and day views, and when a job moves, the customer gets a text that it was moved. Times are offered only where a crew can reach the site from its previous job.
What to take away
- A rain day costs one crew-day. Sliding the whole board costs every customer behind it.
- Book each crew for W − R days a week, using your own rain-day history for R.
- Set the call time and the weather threshold before the forecast turns.
- Move only the job that lost the day, into the float slot.
- Keep weather-flexible work on a list, and re-check drives after any reshuffle.
Common questions
How do roofing companies handle rain delays?
The ones that handle it well plan for it: they book crews below full so there is a float day, decide go or no-go at a fixed time the day before, and move only the job that lost the day rather than sliding every job down the board.
How many float days should a roofing crew have?
Use your own records. Count the rain days you lost per week in each month last year and book each crew that many days short of a full week. Wet months need more float than dry ones.
What can a roofing crew do on a rain day?
Interior and attic inspections, covered repairs, gutter work, material pickups and warranty visits, depending on conditions and your safety rules. Keep the list ready by area.
Should I tell customers about rain delays the night before?
Yes, as soon as your go or no-go decision is made. A fixed call time means the customer hears early and the crew doesn't drive to a site it can't work.
