Winter roofing for contractors: what cold weather costs you, and how to price it
What cold weather does to a roofing crew's cost on a real job: slower installs, hand-sealing, shorter days, dry-in every night. A worked example from our pricing engine, how to price winter jobs, and how to keep the crew busy.
Winter does not change what a roof is made of. It changes how long it takes to put on. That makes labour the line that moves — and if your price does not move with it, the margin does. Here is the cost of cold weather on a real job, priced on our engine, and what to do about it.
The job
A 1,800 sq ft footprint, 6/12 pitch, 2,258 sq ft ordered with 12% waste, architectural shingles, one layer torn off. At our starter rates the homeowner's price is $17,807:
- Materials $6,774
- Installation labour $7,460
- Tear-off $3,048
- Base fee $525
Crew time — installation plus tear-off — is $10,508 of that. That is the part winter stretches.
What cold weather adds
- Slower tear-off and install. Stiff shingles, gloves, frozen debris, careful handling.
- Hand-sealing. Below about 40°F the self-seal strips will not bond on their own; the manufacturer's cold-weather instructions usually call for roofing cement under each tab — material and minutes on every shingle.
- Shorter days. Roughly ten hours of daylight in December against fourteen or more in June across most of the US.
- Dry-in every night. Tear off only what you can cover before dark; that means more, smaller sections.
- Lost days. Snow, ice on the deck and wet mornings that never dry out.
- Storage. Keeping bundles warm enough to work — a heated shop or trailer.
What it costs you on this job
If winter adds this much to crew time, the labour cost of this one roof rises by:
- +10% crew time: $1,051
- +20% crew time: $2,102
- +30% crew time: $3,153
Materials barely change; a full ice and water barrier, if you add it, is about $1,016 more and is a line the homeowner sees. Those percentages are assumptions — measure your own: compare crew-hours per square on your last five winter jobs against your last five summer ones.
How to price winter jobs
- Price the extra labour, not the season. A blanket “winter surcharge” reads as gouging; “hand-sealing and nightly dry-in” reads as care.
- Adjust labour, not materials. In SatelliteQuotes, raise the Labor markup (%) or the Complexity multiplier in Pricing for the winter months, and lower them in spring. Every instant quote on your site follows.
- Make the ice barrier a visible option. As an add-on it is a choice the homeowner makes, not a cost you eat.
- If you discount, discount on purpose — to fill a specific gap in the schedule, with a start date.
Keep the crew busy
The slow season is a pipeline problem that starts in the fall. Three places winter work comes from:
- Homes with a reason. Spring hail reported nearby and no reroof permit in decades; trees over most of the roof (gutters and gutter guards). In Austin, Find customers ranks them from public records.
- Homeowners planning a spring job. An instant quote on your website lets them price it in January and book you before the spring rush.
- Repairs that cannot wait. Leaks found in the first cold snap; answer fast.
Common questions
How much more does winter roofing cost a contractor?
Mostly labour: on this job, each 10% of crew time winter adds is $1,051.
Should roofers charge more in winter?
Charge for the extra labour where winter adds it, and say why; discount only on purpose.
How do roofers get work in winter?
Build the pipeline in the fall: homes with hail and old roofs, gutter-guard candidates, and spring jobs priced early.
