Water that drips into a lecture hall during finals week is a different problem from water that drips into a stockroom, and a campus roof plan has to treat them differently. In West Jordan, UT, a college or university building may combine a flat classroom block, a sloped library entrance, a lab wing with heavy exhaust equipment, and a student center that holds events on weekends. Winter snow and spring melt work on all of them at once, and the first thing we want to learn is which roof sits over the most sensitive room.
Campus buildings tend to be added over decades, so no two roofs share an age, a membrane or a drainage pattern. A roof walk sorts them one by one.
What a mixed-age campus looks like from above
From the top of a stair tower, an older campus often reads as a patchwork. One building has a ballasted single-ply roof with stone sitting on the membrane, the next has a built-up roof with a gravel surface, and a newer hall has a white single-ply with heat-welded seams. Each type fails in its own way. Ballast hides seams and wet spots, gravel drifts into drain bowls, and a white membrane can lose its seam strength where a wall detail was cut by hand.
We begin by recording what is actually on each building, without assuming that a building's age tells us its roof type. Then we probe the details that matter most: wall terminations, expansion joints between building phases, and the curbs around the mechanical units that serve labs and server rooms. Photographs tie each finding to a nearby drain or unit so a campus facilities team can find it again.
Drainage and melt: after the thaw
Salt Lake City's airport has logged winter snow, cold-season freezing and hot summers for decades, and that record is the nearest thing to a local reference for a campus in West Jordan. The cycle it points to is what tests a campus roof: snow cover, afternoon melt, overnight refreeze, and a drain path that must stay open through all of it.
On a campus, the drain path is often long. Water from a high roof may be routed across a lower roof, onto a plaza, or down a leader that runs inside a wall chase. When one of those links freezes or clogs, the ponding that results shows up in a room far from the actual cause. After a thaw we follow each leader from the roof outlet to the point of discharge and note any place where ice or debris has narrowed the path.
Labs, server rooms and rooftop equipment
The roof over a lab or a data closet carries more equipment than the roof over a classroom, and every support leg and conduit is another place for water to find a way in. Exhaust stacks need flashing that tolerates heat and chemical vapor. Air handlers need curbs that stay tight when the unit vibrates. Piping that crosses the roof needs supports that do not puncture the membrane when they move.
Where the building houses research equipment or sensitive storage, we ask the facilities office to mark the rooms below that cannot take a leak and plan the roof work from there. A temporary dry-in plan is written first, with tarps, sandbags and standby material staged, so that if a repair opens an area, it is closed again at the end of the shift.
Semester timing and event weekends
Campus work follows a calendar that most commercial buildings do not have. Orientation, move-in, midterms, finals, commencement and athletic events all affect crane placement, parking and noise. We work with the facilities office to find windows that avoid those weeks, and we build materials lead time into the plan so a membrane ordered in spring arrives before the summer session ends.
For work that has to happen while classes meet, we sequence by section. A lecture hall that is empty at midday may be full at four in the afternoon, so crews do the noisiest work early and close up before the evening lectures begin. Hoisting and material staging stay away from student walkways and fire lanes, and the crew uses a single gate with a sign-in sheet that the campus security office can review.
Campus roofs and the Salt Lake Valley
Planning in West Jordan favors regional commercial, office and mixed-use growth, with I-15 and I-80 nearby and a UTA Red Line that stops at the West Jordan City Center and Jordan Valley stations. A campus that sits near those corridors shares them with delivery trucks and neighboring construction, and that matters for the roof: crane access, delivery routes and the staging area all affect how a project is sequenced.
Owners in West Jordan, Murray and Sandy can ask for the same plan format on every building, so a campus with a dozen roofs sees them ranked by urgency. A building with a lab wing may be handled differently from a K-12 school roof, but the roof walk steps are the same. Where the budget allows, a capital plan sequences replacements over several fiscal years.
Repair, coat or replace
A campus roof has three realistic paths. Repair is right when the membrane is sound and the problem is a detail. A coating restoration fits a roof with a dry base and a surface that has weathered, since it can add life without a tear-off. A replacement is the call when wet insulation has spread or the membrane has gone brittle. We test before recommending, with a moisture meter and, where the roof is large, a scan of the whole surface.
Cost and timing follow the same findings. A repair on a single wing can be priced after one roof walk. A coating needs a clean, dry surface and a stretch of warm, dry days, so it fits the late spring or summer weeks. A replacement needs the longest lead time, because the insulation, cover board and membrane are ordered to the final roof plan. A hospital roof or a student health building on the same campus may have stricter rules for noise and air intakes, so we ask for those rules during the first walk rather than after a crew is on site. Wet readings that spread across a wing are the signal to stop patching and weigh a larger scope, and a written comparison of the paths lets the budget office pick one.
Commercial Roofing Questions
Can the work avoid exam weeks and commencement?
Yes, if the dates are known early. We build the schedule around the academic calendar, order materials ahead of the summer session, and keep crane placement clear of event traffic.
How do you protect a lab below a roof repair?
A dry-in plan is written before the first cut. Tarps, sandbags and standby materials are staged, and the work area is closed up at the end of each shift so no opening is left overnight.
Why does water appear in a room far from the roof drain?
Leaders on a campus often run through wall chases and across lower roofs. A frozen or clogged link moves water sideways before it drops, so we follow the whole path from outlet to discharge.
Do older buildings need a different approach from newer ones?
Each gets tested for what is actually there. A building's age tells us little about its membrane, so we probe seams, check details and read moisture before we recommend a path.
What does a facilities team get at the end of a visit?
A written plan with photographs, repair locations measured from fixed points, moisture readings and a ranking of buildings by urgency, ready for a budget meeting.
