Commercial roofs need regular inspections because small problems around seams, flashing, drains, penetrations, and roof edges can develop into larger leaks if they are not identified early. Spokane weather can place additional stress on commercial roofing through snow, wind, rain, and repeated temperature changes. Our inspection process reviews visible roofing materials and common problem areas so property owners can understand the current condition of the roof. Buildings in Downtown Spokane and other developed areas may also have rooftop equipment and penetrations that require careful inspection.
During an inspection, we look for damaged or deteriorated roofing materials, loose flashing, drainage concerns, visible punctures, failed sealants, and signs of moisture intrusion. If problems are identified, targeted commercial roof repair can address affected areas before they become more extensive. Regular commercial roof maintenance can also help keep drainage systems, seams, flashing, and other roof components in better condition between inspections.
Severe weather can create problems that are not immediately obvious from the ground. Strong winds may loosen roofing materials, while heavy snow and ice can place additional stress on roof surfaces and drainage areas. After a significant weather event, a storm damage assessment can provide a closer review of areas that may have been affected. If the inspection identifies substantial deterioration across the roof, a commercial roof replacement may need to be considered based on the overall condition rather than a single damaged area.
The appropriate inspection schedule depends on the roof type, age, exposure, previous repairs, and condition of the property. We focus on documenting visible concerns and identifying areas that may require maintenance or repair. Commercial properties in Comstock and throughout Spokane can use regular inspections to keep track of roof conditions and address developing problems before they interfere with the building.
Technician insight
In Spokane, the thing that catches most people out with Commercial Roof Inspection is how quickly snow load and freeze-thaw cycles open seams on 30-year-old metal roofs along the South Hill; owners often skip checking the north parapets where drifting snow sits longest.
Warehouse Roof on East Sprague
Water was entering a tenant space after a heavy March melt. The inspection revealed saturated insulation around two clogged scuppers and lifted seams on the 25-year-old EPDM. We documented the wet zones, cleared the drains, and provided a targeted repair plan that stopped the leaks without full replacement.
Commercial Roof Inspection Services We Offer
✓Flat Roof Membrane Inspection
Checks seams, flashings, and ballast on TPO, EPDM, and modified bitumen systems common on Spokane warehouses for early signs of delamination caused by thermal cycling.
✓Metal Panel Roof Assessment
Examines panel fasteners, sealants, and ridge caps on standing-seam and screw-down roofs found throughout Spokane County industrial parks for corrosion and wind uplift damage.
✓Drainage and Scupper Evaluation
Tests flow rates and clears debris from internal drains, scuppers, and gutters on commercial buildings near the Spokane River where pine needles and ice frequently block outlets.
✓Skylight and Penetration Sealing Check
Inspects curb flashings, counterflashing, and sealant around HVAC units and vents on retail roofs in the East Sprague corridor where thermal movement opens joints every winter.
✓Snow Load and Ice Dam Review
Measures insulation depth and assesses drift patterns on low-slope roofs in South Hill neighborhoods to confirm the assembly can handle Spokane's typical heavy snow accumulations.
