The replacement plan explains tear-off or recover assumptions, insulation and drainage needs, occupied-building phasing, system options, and closeout requirements. Tear-off is the part of a reroof where the building is most exposed. Every section we open has to be dried in before weather moves through, and every load of old membrane and insulation has to come off the roof without damaging landscaping, parking areas, or dock traffic below. That logistics side of the job is where a lot of reroof problems actually start.
Most of the buildings we tear off in the Evansville area stay in use during construction, a distribution center still running trucks through its dock doors, a retail strip still open to customers, a school still holding classes. We set up staging areas that keep debris chutes, dumpster placement, and crane swing radius away from active entrances and loading zones. On tighter urban sites near downtown, that sometimes means running material off the back of the building instead of the front, even if it adds steps to the crew's day.
Ground protection matters here too. Plywood or mats go down under staging areas and crane outrigger pads before anything gets set, particularly on softer ground after a wet spring, which is common in this part of the Ohio Valley. We'd rather add an hour of prep than leave ruts across a parking lot or a client's landscaped entrance.
A lot of older commercial buildings around Vanderburgh County have been recovered once or twice already, which means tear-off is working through stacked layers of built-up roofing, insulation, and sometimes gravel ballast, not a single membrane, adding real weight to every load. We plan disposal volume based on a pre-job core sample, not a guess, so dumpster counts and haul schedules are accurate instead of causing a mid-project scramble.
Each layer gets pulled back in daily sections sized to what the crew can dry in before end of shift. On a hot, humid Evansville afternoon, an open deck left overnight is an invitation for condensation to form underneath a temporary cover, so we'd rather cut the day's section smaller and finish it clean than leave anything exposed and hope the tarps hold.
Every tear-off is also a deck inspection. Steel deck panels near old roof drains or scuppers are where we most often find corrosion from years of standing water finding its way through minor breaches. Wood nailers at the perimeter rot out from the inside long before they look bad from above. None of that gets covered up, damaged sections are cut out and replaced, and fastener patterns get rechecked against current wind uplift requirements before insulation goes back down.
Spring and early summer thunderstorm season is the trickiest window for tear-off scheduling here. A clear morning in the Tri-State can turn into a line of storms by mid-afternoon, so we track forecasts daily and adjust section sizes down when the radar looks unsettled. We'd rather move slower and stay dry than push a large section open and get caught by a fast-moving cell off the river.
Humidity is a factor even on rain-free days. A deck that sits open too long in Evansville's summer air picks up moisture from the atmosphere alone, which is one more reason our crews favor conservative daily sections over racing to finish tear-off in the fewest possible days.
We stage insulation, cover board, and membrane rolls on the roof in the sequence they'll actually be installed, which keeps foot traffic and material handling to a minimum on a deck that's just had old roofing pulled off it. Reducing extra trips across a newly exposed deck lowers the chance of a stray puncture or a dropped tool finding a soft spot before the new system is even down.
Yes, in most cases. We sequence work and stage materials to keep entrances, dock doors, and parking areas clear, adjusting the plan based on how the specific building operates day to day.
Sections are sized so they can be fully dried in before the crew leaves for the day, and we track weather closely enough during storm season to shrink that section further if conditions look unstable.
We pull core samples ahead of the job to confirm how many layers and what type of insulation is underneath, which lets us plan disposal volume and crew time accurately instead of guessing.
Sometimes, particularly around old drains, scuppers, and parapet walls where water has had years to work its way in. Any damaged deck or nailer gets replaced before new insulation goes down.
Dumpster placement and haul routes are planned around active entrances and dock traffic, with removal scheduled to match daily tear-off progress rather than letting debris pile up on the roof.
