A new tenant moves into a building, a technician cuts a hole in the roof for an exhaust duct, and the first leak report arrives in January with no record of who made the cut or how it was flashed. In Taylorsville's planning, the 2700 West Employment Center is an emerging place of local jobs; the city sets it on the planned Midvalley Connector BRT corridor, and is studying commercial centers and properties along the planned bus rapid transit line for future development. An emerging area is one where tenants, owners, and uses are changing, and roofs take the brunt of that change. Our first walk records the roof as it is, follows the snowmelt path from the drain bowl to the open seam, and lists every penetration with its flashing.
Tenant changes and the roof: what new work leaves behind
Each tenant improvement can put something on the roof: a new rooftop unit, a vent, a conduit run, a satellite mount. Without a record, no one knows who installed what, whether the curb was flashed to the membrane's requirements, or whether the added weight was checked against the structure. We map every penetration and unit on the first walk and mark the ones that look newer than the membrane around them.
Curbs set by a mechanical contractor and flashed in a hurry are a common source of early leaks. We check sealant, termination height, and corner details, and we note any penetration that lacks a proper boot. The map gives the owner a list of items to correct and, for future tenant work, a rule: any roof cut goes through the roofer, and each one is flashed to the membrane manufacturer's method and photographed.
Planned transit work: dust, vibration, and edge conditions
Taylorsville's plan places the employment center on the planned Midvalley Connector corridor, and the city is studying properties along it. A plan is not a schedule, and no roof decision should rest on the idea that construction will begin by a given date. But if street or station work does come near a building, it brings dust into drain bowls, vibration through walls, and foot traffic where there was none.
The practical response is a baseline. A dated roof walk with photographs of drains, edges, equipment, and interior ceilings gives the owner a before-picture. If damage appears after nearby work, the owner can compare. We also check parapet caps and wall flashings for movement before any heavy work begins, since a wall that shifts slightly can open a flashing that held for years.
Snow, melt, and the check that follows
Averages from the weather station at Salt Lake City's airport show winters with snow on the ground, warm summers, and freezing spells. They stand in for the region, and the exposure of a specific Taylorsville roof may differ. They justify a habit of checking after melt, which is when the cycle of thaw and refreeze has had a chance to push water into a weak spot.
Our post-melt check starts at the drain bowls, clears debris, and notes whether water stands. It continues along the low spots, then to seams and flashings along the path between. A shaded slope holds ice longer and keeps its seams wet; a sun-facing slope dries early and shows movement at curbs. Stains inside, matched with the weather in the days before, tell us which day the water got in and what kind of event it was.
Repair, recover, or replace: the evidence for each
With the walk and a moisture map in hand, the repair line is set. A handful of failed details with dry insulation is a repair. A weathered but sound membrane over dry insulation can take a coating. Dry board and a modest layer count permit a recover. Wet insulation across a wide area points to replacement.
The proposal sets out each path with its cost drivers: layers on the roof, wet material, equipment to lift or flash, access, and season. Owners weighing an investment in an emerging area often want the roof decision to fit a longer plan, and a staged approach lets them repair what leaks now while setting a year for the larger scope.
Ceiling stains: reading the pattern from inside
The ceiling below a roof keeps a record of every leak, and the shape of the stain says something about the cause. A round brown ring with a darker edge usually marks a point entry, such as a failed pipe boot, where water dripped steadily from one spot. A long streak that follows a line points to a seam or a wall base, where water ran along a deck before it dripped. A wide, faint cloud suggests slow seepage through wet insulation.
We photograph the stains, measure them, and mark them on the roof sketch before going outside. Stains that line up with a unit or a wall point to the details nearby. Stains with no obvious link often point to a drain or to wet insulation that carried the water sideways. The match between inside pattern and outside finding is what tells us we have the right cause, and it is the proof the owner needs before approving the repair.
Added equipment and the structure beneath
When a tenant adds equipment, the roof structure carries more than it did. Units sit on curbs that transfer weight to the deck or to framing, and heavy additions may require reinforcement. We do not design structure, but we note where equipment has been added, where the deck looks deflected beneath it, and where ponding has formed since.
A deflected deck holds water, and water adds weight, so a small dip can grow. When we see one, we record it with a measured depth and recommend a structural review before more equipment is added. The record gives the engineer a starting point, and the owner an answer to whether a new unit can go where the tenant wants it. If the engineer approves, the curb is set on a spot over a bearing line, the flashing is detailed to the membrane, and the added weight is entered in the roof log with the date and the unit's make, so the next owner knows what the roof is carrying.
One record format for every building
An owner with several properties, in the park or beyond it, benefits from a single format: membrane, area, drains, equipment, age, repair log, last walk. Owners of property in the Sorenson Research Park, the Redwood Road commercial corridor, or Taylorsville generally can follow the same calendar. A maintenance visit after each melt keeps drains clear and details tight, and the log shows it.
Commercial Roofing Questions
Why does a roof need a record when tenants change?
Each tenant may add equipment or cut openings. A record shows who did what and whether it was flashed correctly. Without it, leaks become arguments.
Does a planned BRT line affect my roof today?
Not by itself. Plans are not construction. A baseline walk now gives you a comparison if work begins nearby later.
Who should cut a hole in my roof?
The roofer, or someone working under the roofer's flashing method. Mechanical contractors can set equipment, but the opening and its flashing should be photographed and recorded.
How do you tell if a deck is deflecting?
By ponding patterns, by a measured dip in the surface, and by looking at the structure from below where possible. A structural engineer confirms the cause.
Can you stage roof work for a multi-tenant building?
Yes. We divide the roof into sections, protect the interior below each, and keep a log of what was opened and closed each day.
Tell us who works under the roof and what changed
Send the tenant list, any known roof cuts or added units, and the dates of leaks. We will walk the roof, map the penetrations, and set the repair line or next test from what we find.
