A flashing that will not stay stuck is the kind of problem that liquid-applied systems were made for, and the kind that bitumen sheets handle by overlap and heat. Soprema supplies commercial roofing in both families, with bitumen-based membranes, liquid-applied membranes and insulation among its offerings, and owners in West Jordan, UT may find either under their feet. We install, repair and maintain systems of these types. On such a roof the first questions are about details and layers: how are the transitions built, what is under the surface and where did the winter put water?
What failed first on a bitumen-based roof
Bitumen sheets are lapped and sealed, and the laps are where they fail first. A lap that has opened shows a dark gap or a ridge. Surfacing granules wear away from foot paths and from the sun-facing slope, and the exposed asphalt ages. Splits follow insulation joints where the roof has moved. Blisters point to trapped moisture or air between layers.
We walk the roof in sections, mark each defect and photograph it. We look at laps at walls, at drains and at penetrations, since those are where the roof is cut and the sheet rewrapped. Where the surface has gone bare over a large area, we measure the extent. A coating over a sound but worn surface is often the least expensive way to add years.
Ponding is hard on bitumen. Standing water softens surfacing, speeds aging and, in a freeze, works at laps. We measure depth and duration, find the cause and decide whether drainage can be corrected with a drain, a cricket or tapered insulation. Where the cause is deck deflection, we say so, and a structural review comes before any new load goes on.
Roof-walk notes: liquid-applied details
Liquid-applied membranes are troweled, rolled or sprayed on, then cure into a continuous layer. That makes them useful at awkward shapes: pipe clusters, curbs with odd corners, drains and wall transitions where sheet material is hard to detail. They fail differently from sheets. Instead of laps opening, a liquid layer can thin at edges, crack where the substrate moves or lose adhesion if the surface was dirty.
We look for thin areas, cracking, pinholes and lifted edges, and we check where the liquid layer meets sheet material. Reinforcement fabric embedded in the layer is part of what we examine. A liquid detail that is repaired needs a clean, dry, compatible surface and a cure window, which in the Salt Lake Valley means warm, dry days.
Drains and penetration clusters are where liquid systems earn their place. A drain bowl ringed by old patches can be reflashed with a reinforced liquid detail that bonds to the bowl and the field in one layer. Pipe clusters, where cutting and fitting sheet material would leave seams, can be built up in liquid with reinforcement. We test adhesion on the existing surface before proposing it, because a liquid detail over a dirty or incompatible surface will peel.
Drainage and melt: winter and summer limits on the work
Cold limits the work: Salt Lake City airport normals describe the valley's snowfall and freeze-thaw periods in regional terms, and the list of repairs that can be made in winter is short. Local elevation and exposure vary from the airport's record. Cold surfaces slow or block cures and bonds, so winter work is usually temporary: tarping, patching with cold-weather materials and clearing drains.
Summer brings heat, and some bitumen and liquid products have working limits on hot surfaces. We schedule temperature-sensitive steps for cooler hours and keep materials shaded. In spring, after melt, we walk the roof, check drains and edges and mark the repairs that need a proper window. The calendar matters as much as the product.
West Jordan's general plan lists planned station districts at Gardner Village, Old Bingham Highway and the Redwood Road and 7800 South core. Wherever construction happens nearby, dust and debris end up in drains and on surfaces, and a roof walk after a nearby project is a sensible habit. Either way, the roof gets walked after melt.
Methods, fumes and occupied buildings
Some bitumen methods use heat, and some liquid products give off odor while they cure. Both matter on occupied buildings. We choose the method with the building in mind: fresh-air intakes near the work, tenants with sensitive operations and access to the roof. Cold-applied or adhered methods avoid open flame, and low-odor products are available for many details. Where the choice is not obvious, we explain the tradeoff to the property manager.
We cover or shut down intakes during the work when the tenant agrees, plan hours around occupancy and keep a fire watch where heat is used. Daily closeout includes cleaning, material security and photographs of each tie-in.
Fire safety is its own plan. Where heat is used, we set up extinguishers, keep a watch for the required time after work stops and check surfaces and voids for hidden heat. Torch work near combustible substrates or voids is avoided in favor of other methods. The plan is written down and shared with the property manager before the first day.
Repair boundary, code and warranty
Where defects are located and the roof is dry, a repair is enough. A worn but dry surface can take a coating. Wet insulation or failed layers call for replacement. The price follows roof area, the depth of tear-off, the insulation and the number of penetrations. Energy provisions in Utah's 2024 codes come into play when a replacement exposes insulation. Any added insulation is priced on its own line.
A warranty from the manufacturer may limit who repairs the system and demand notice before work starts. We help owners read their terms and keep a roof warranty management record. For roofs with several layers, modified bitumen roofing repairs follow the same rule of matching material to what is there.
Insulation decisions belong in the scope. Wet boards come out, dry boards stay and the new layers are fastened or adhered to the manufacturer's published patterns where we know them. A cover board over the insulation protects it from traffic. Tapered boards correct slope. Each is priced on its own line, so the owner sees what it adds.
Next check: what to send
Send the address, any roof papers and where water shows up, and say which tenants sit below and how the roof is reached. The walk identifies the system, probes laps and details and reports what to repair first. A portfolio with Johns Manville or Duro-Last roofs gets the same walk building by building, and a property in West Jordan is walked on a day the tenants can plan around.
Commercial Roofing Questions
Why do laps open on a bitumen roof?
Heat, cold and movement work on the seal over time. Laps at walls, drains and penetrations see the most stress.
Can a liquid layer be applied in winter?
Usually not for permanent work. Cold, damp surfaces block cure and bond. Winter work is temporary, and permanent repair waits for a dry, warm window.
What is reinforcement fabric for?
It strengthens a liquid layer at details and across cracks, so movement does not split the coating.
Will repair work bother tenants?
Some methods give off odor or heat. We choose methods for the building, protect intakes and plan hours around occupancy.
Who backs the product warranty?
The manufacturer, under its own terms. We handle the installation, the repairs and the records, and warranty terms stay with the owner.
