The replacement plan explains tear-off or recover assumptions, insulation and drainage needs, occupied-building phasing, system options, and closeout requirements. Tear-off and replacement means stripping the existing roof down to deck and rebuilding the assembly from that point up. It's the most disruptive roof work a building goes through, and it's also the only way to fix problems that live below the membrane - soaked insulation, corroded deck, or a slope that was never right to begin with. We plan replacement projects around getting your building weathertight again as fast as the sequencing allows.
A recover - installing a new membrane over the old one - only works if what's underneath is dry and structurally sound. On a lot of the older manufacturing and warehouse buildings around the rail corridor and the industrial blocks off Shenandoah Avenue, that's not the case. Decades of minor leaks have left insulation waterlogged in patches, and covering that over just traps the problem. Tear-off is the honest answer once a moisture survey shows saturation beyond isolated spots.
We also push toward tear-off when a roof has multiple membrane layers already stacked from prior recover jobs - code and weight limits cap how many layers a deck can carry, and buildings that have been recovered twice are usually out of room.
Tear-off generates a lot of debris, and how it's staged matters on a working site. We coordinate dumpster placement and loading routes around active dock doors and parking, which is a real constraint on tighter urban sites downtown and around the medical campus, where truck access competes with deliveries and patient traffic.
Once the old roof is stripped, we inspect the exposed deck directly rather than assuming it's fine. Steel deck near the rail yards sometimes shows corrosion from decades of condensation cycling; older wood plank decks on some of the pre-war commercial buildings downtown need individual board assessment. Any deck repair happens before a single board of new insulation goes down.
Some of the pre-war commercial buildings downtown and along the older industrial blocks have been reroofed multiple times without a proper tear-off, leaving two or even three membrane systems stacked on the original deck. Removing that requires more labor and disposal capacity than a single-layer tear-off, and it also means we don't know what condition the original deck is in until every layer comes off. We scope multi-layer tear-offs with contingency built in, since the surprises tend to show up only once the last layer is gone.
This is also where asbestos-containing materials sometimes turn up on buildings old enough to predate modern roofing material regulations. We flag that possibility upfront on any building constructed before the 1980s and coordinate testing before tear-off begins if there's reasonable cause for concern.
The valley's weather swings are the biggest scheduling variable on a tear-off. A summer afternoon storm building over the ridges can turn a dry morning into a race to get a section dried in, and winter tear-offs have to work around the cold snaps that come through fast enough to freeze standing water on an open deck. We track short-range forecasts daily during active tear-off phases and never leave more deck open overnight than we can protect if conditions turn.
Replacement is a chance to correct choices made decades ago. A distribution building near the I-81 corridor with heavy rooftop unit loading gets a fastening pattern and membrane thickness sized to that load, not whatever was standard when the building went up in the 1980s. A building on higher ground near the ridgelines that sees stronger sustained wind gets uplift-rated fastening to match, rather than the lighter pattern that might be fine on a sheltered valley-floor site.
Manufacturer warranties on a full tear-off and replacement are typically stronger than what's available on a recover, because the installer has full control of the assembly from deck up. We document deck condition, insulation R-value, and fastening pattern at each stage so the paperwork supports the warranty claim if anything comes up years down the road.
A moisture survey with core cuts tells us. If saturation shows up beyond a few isolated spots, or if the roof already has multiple membrane layers stacked from past recovers, tear-off is the only sound path forward.
We stop and assess before installing anything new. Deck repair or replacement happens as its own step, priced and scoped once we can see the actual condition rather than guessing from the surface.
Tear-off is noisier and more visible than a recover, but we still section the work so occupied space stays covered and dry each night. We coordinate loud phases and debris hauling around your operating schedule where the site allows it.
Often it costs less over a multi-year horizon, since repeated emergency repairs on a failing roof add up and don't fix the underlying saturation. We'll walk through the moisture survey findings so the comparison is based on your actual roof, not a general rule.
Yes. We field-verify curb heights, unit weights, and penetration locations before ordering materials, so flashing and support details are built for the equipment that's actually up there.
