Brown rings on ceiling tiles the week after a thaw are usually the end of a longer story, and on a commercial property that is about to change hands it becomes the first line of a negotiation. Taylorsville, UT is studying land-use opportunities along the Expressway and its planned Midvalley Connector BRT route as commercial properties turn over, and the city identifies three station areas: Riverboat Road, Atherton West and 1300 West. Turnover is when a roof gets looked at by people who have never been on it, so we begin a corridor roof walk by asking what the next owner, lender or tenant will want to know: where water leaves the roof, what has been patched, and what has not been opened.
The visit itself is simple. Water is traced from the point where it leaves the roof back to the low area, seam or edge that feeds it, and the notes separate what is sound from what has moved.
What failed first: the record, not the membrane
On a property that is changing hands, the roof problem is often a missing file. Nobody can say when the last repair was made, which section was recovered or where the drains discharge. A buyer's inspector sees a patch and has no way to tell whether it is a one-time fix or the fourth attempt at the same seam.
We start with what can be seen and photographed: the seam lines, the drain bowls, the edge metal, the curb corners and any tar or sealant that was added later. Each finding gets a location on a simple roof sketch. Where the evidence runs out, we say so and name the small test that would settle it, such as a moisture reading, a single core or an infrared moisture survey of the doubtful area.
Roof-walk notes: what the next owner reads
A useful condition record is brief enough to read and detailed enough to price from. Each roof section appears with the system we think is on it, its drainage path, its penetrations and a photograph pinned to the sketch. It separates leaks that need prompt work from wear that can be watched.
- Drain bowls, strainers and the path from each to the outlet
- Open or lifted seams and the edge metal around them
- Rooftop equipment curbs and the membrane turn at their corners
- Prior patches, with a note on whether they are holding
- Low spots where water stays after the surface has dried elsewhere
A due-diligence roof survey packages the same notes for a buyer or lender who has not seen the building.
Drainage and melt: a valley-wide reference
Airport weather normals from Salt Lake City describe a valley with winter snow, warm summers and a freezing cold season. They explain why, after a melt, we look at the drain path and the seams that sit on it before we look anywhere else.
Snow that thaws on a sunny slope and freezes again at an eave or in a drain bowl can force water under a lap or behind a flashing. The pattern is a reason to look, and the roof itself supplies the diagnosis. If snow is still covering a detail on the day of the walk, the record says which areas were visible and which need a second look once the roof is clear.
Summer adds its own wear. Summer works from the other side: a dark membrane on a sunny slope runs hotter than the air over it, swelling by afternoon and shrinking overnight. Seams, curb corners and wall bases feel it first. A hairline gap at any of them can become, over a few seasons, the open seam a thaw will find.
Repair boundary: patch, test or replace
A patch fits when sound membrane surrounds it and the new edge has something good to bond to. Leaks that keep returning to one zone, wet insulation or a soft deck can push the repair line outward. The boundary goes on paper with its reason, together with anything concealed that could change it.
Price and schedule depend on how many layers sit on the deck, how much insulation is wet, how many penetrations there are, how crews reach the roof and what happens in the building below. If the owner is weighing a repair now against a replacement timed to the sale or lease, both routes get a price and the evidence sits beside each.
Where a roof has been recovered once already, the next decision is stricter. A second recover adds weight and can bury wet insulation, so a test area is opened before anyone agrees it can be done.
Seasonal timing: work around roads and station areas
A BRT corridor means roadwork, detours and changing traffic patterns while station areas are built or adjusted. We ask the manager about lane closures, loading windows and parking, then choose lift positions and delivery times that stay out of the way. Materials come in small loads when the street is quiet, and the crew stages them on the roof or in a fenced area at the side of the building.
The roof schedule also follows the weather. Adhesives and welds have a working temperature range, and nothing opens that cannot be dried in before the crew leaves. A spring check finds winter damage early; a fall check clears the drains ahead of snow.
Where a station area brings new foot traffic, we also note which roof edges sit above walkways, so any loose metal or hanging ice can be dealt with before it becomes a hazard.
Next check: what to send before the roof walk
A roof plan if one exists, leak dates and rooms, earlier repair invoices and the sale or lease schedule tell us how big the record needs to be. Owners with other property in West Valley City or Murray can use the same format at each building.
Say where water appears, when it appears and how the roof is reached. From there we describe the next roof walk and list what must be confirmed before a repair boundary or a calendar is fixed.
Commercial Roofing Questions
Can the roof be inspected before a sale closes?
Yes, if access is arranged. Visible conditions are photographed, hidden ones are marked as unseen, and the open questions come with the tests that would answer them. The same list tells a seller what to repair before listing and what to disclose.
Does the BRT corridor change how the roof is accessed?
It can, through lane closures and parking changes. We ask about them first and set lift positions and delivery times to avoid them. Material arrives in small loads outside peak traffic.
What does a roof record cost the owner in time?
A first walk and a short written record. The sketch and photographs do most of the work. We send photographs and the sketch the same week so the file is ready when the negotiation needs it. Photographs and a pinned sketch are what carry the file from one owner to the next.
Should snow cover delay the inspection?
Only for the covered details. The visible parts get inspected, the covered ones get noted, and a return visit follows once the roof clears. A visit after the thaw closes whatever stayed open.
Which edition of the building code applies?
Utah's 2024 building and energy codes became effective July 1, 2026, with state and local amendments. Permit staff confirm which edition governs an application. Energy-code requirements for insulation can also change the replacement scope.
Start with where the water showed up
Tell us which room or roof section is affected, when the leak appears and how roof access works. We will walk the likely path, record what we see and set the next test or repair boundary from the evidence.
