A Johnston roof can look fine from the driveway and still be backing water under the shingles at the eave, where nobody can see it. As part of our complete Johnston winter roof services, crews handle crane-assisted snow removal across Polk County.
Why Johnston Roofs Dam Up: Cycling, Not Snowfall Totals
An ice dam needs meltwater and a cold eave, and Johnston supplies both on an ordinary week. A thin cover that melts by lunchtime and sets again after dark is a perfectly good dam factory.

Because the winters read as mild, the building stock is not built for ice. Attic insulation is thinner, eave details are less considered, and ice barrier is more often absent than present on a roof in Johnston.
Ice-barrier practice in Polk County
Because ice is not the first thing a homeowner in Johnston thinks about, the membrane is the detail most often value-engineered out of a re-roof. It is worth asking for by name on any quote.
Crane-Assisted Snow Removal in Johnston: How The Work Runs
When a crane is the right call
Multi-story homes and estates where the upper roof cannot be safely reached. Large commercial and industrial decks where the sheer tonnage makes hand clearing a multi-day job. Any roof where deflection is already visible and the load has to come off today rather than over a week. Ceiling Sagging or Bulging After Snow.
The decision is made on numbers, not instinct. Depth, density and area give a working load figure, and that figure against the roof's design capacity is what determines whether a crane gets mobilised to a property in Johnston.
What happens if the crane cannot get close enough
Overhead power, a narrow alley, soft ground that will not take outrigger loads, or a neighboring building in the swing path can all rule out a setup after a site visit.
That gets found on the walk rather than on the day. Where a crane genuinely will not work, the honest answer is a larger hand crew over more days with the cost difference laid out - not a pick that was never going to fit.
Why it is often the cheaper number
Per hour a crane costs more than a crew with shovels. Per roof it frequently costs less, because a pick that takes an afternoon can replace several crew-days of hand clearing.
On a large Johnston deck the crane is routinely both the faster and the cheaper answer, and the comparison gets shown rather than asserted.
How a pick actually works
Rip-stop tarps are laid out and anchored on the deck, crews load them, and the boom lifts each loaded tarp clear and sets it down in a designated drop zone on the ground. Outrigger pads are placed on frozen ground rated for the load, and a pedestrian exclusion zone is set and marshalled for the whole operation.
It is a planned lift, not an improvisation. Site access, swing radius, overhead lines, drop zone and ground bearing all get walked before the first tarp goes down.
Traffic control and the street closure conversation
A crane set up in a street needs the street. Depending on the municipality that means a permit, cones and flaggers, a parking suspension, or all of it, and the lead time is days rather than hours.
Those applications get made as part of the booking. Discovering on the morning of the lift that the road cannot legally be occupied is an expensive way to learn the local rules in Polk.

Neighborhoods and Towns We Reach From Johnston
Crews working Johnston cover the adjoining communities on the same route — Grimes, Clive, Polk City, Berwick and Granger — so a storm week usually means one truck handling several addresses in Polk County rather than separate trips.
Nearest hub towns with their own crane snow removal pages: Urbandale, Ankeny, West Des Moines, Des Moines, Waukee, Ames.
During a cold snap Johnston gets worked alongside the neighboring Polk County towns on the same route, with active interior leaks moved to the front of the list.
Most jobs do not stop at one service. Crane Snow Removal in Johnston often runs alongside commercial roof snow removal in Johnston, and both get written into one scope rather than billed as separate visits.
