What Should a Fall Commercial Roof Inspection Include in Boise?
A fall commercial roof inspection in Boise should cover the drains and scuppers, every seam and flashing, the curbs around rooftop equipment, the membrane condition, and any spot that ponds water, with repairs finished before the first hard freeze in late October or November. Dodd Roofing and Exteriors inspects flat and low slope commercial roofs across the Treasure Valley every fall so building owners head into winter with closed seams and clear drainage instead of a leak over a tenant space in January.
Why does fall matter more than spring for flat roofs in the Treasure Valley?
Boise summers are hard on single ply and modified bitumen membranes. Weeks of 95 to 100 degree afternoons dry out sealants and pull seams open as the membrane expands and contracts. A fall inspection closes those openings before rain gets in. Water that enters a seam in November freezes, expands, and widens the gap with every thaw cycle through March.
What does the inspector check on the roof surface?
On TPO, EPDM, and mod bit roofs we walk every seam looking for separation, fish mouths, and lifted laps, then check for punctures, blisters, and shrinkage pulling at corners and walls. Dirt rings show where water sits after a storm, and those low spots are where winter ice builds first. Our post on
explains what to expect from each material.
Why are drains, scuppers, and flashings the biggest risk?
Most winter leaks on commercial roofs in Meridian, Nampa, and Garden City start at a clogged drain or a failed flashing, not in the open field of the roof. Cottonwood fluff and leaves collect at drains and scuppers. A blocked drain means ponding, and ponding plus a freeze means added weight and water pushed under laps. We clear every drain, then check flashings at HVAC curbs, pipe penetrations, pitch pockets, and parapet walls, since these dry out faster than the membrane itself.
What about rooftop equipment and foot traffic?
Fall is when HVAC contractors service rooftop units before heating season. Dropped screws and foot traffic off the walk pads leave punctures nobody notices until water shows up inside. We recommend a quick roof check after any other trade has been up there.
Should the inspection include the interior and a written report?
Yes. We look for ceiling stains, damp insulation, and rust on deck fasteners. You receive a photo report with a priority list that separates what needs repair now, what can wait until spring, and whether the roof is a candidate for repair, a coating, or replacement. Our
and
pages explain each option.
When should Boise building owners schedule it?
Late September through October is the window. Seam repairs and sealants cure best when daytime temperatures stay above 50 degrees, and the first November storms tend to bring wind and rain together.
