School Roofing in Missoula, MT

A school roof has to be finished in the order the calendar allows, and the calendar allows very little. The summer break gives a few weeks, the snow gives the rest of the year back to winter, and any job that runs past the first day of classes becomes a safety problem for children walking under a staging area. Missoula County Public Schools employs about 1,450 people, and school buildings in Missoula, MT carry roofs that must be dry before the first thaw cycle of the school year. We lay out school roof work by sequence first and price it second, so the district sees which weeks hold tear-off, which hold dry-in and which are held back for weather.

The first question is always what fails first, and on a school the answer is usually a drain, a flashing at a mechanical well or a seam that has opened through repeated freeze and thaw.

The sequence for a school replacement starts months before the crew arrives. Materials have to be ordered so the rolls and insulation are on site by the first day of summer break. The laydown yard has to sit where buses and delivery trucks do not cross it. The crane pick has to happen while the grounds are empty.

Each roof area becomes a phase with its own tear-off, dry-in and punch list. We never open more roof than the crew can close in a day, and we protect the interior with the usual temporary measures when a section has to stay open overnight. When a district has several buildings, we rank them by remaining service and spread the work across summers, so one budget year does not carry the whole program. A commercial roof replacement on a school near North Reserve Street or in the University District that starts in June and finishes in August leaves the building with a full weather window in reserve for punch-list items.

Winter does most of the damage on a Missoula school roof. About 45 days a year never rise above freezing, and thaw cycles then work water into every opening. A drift against a gym wall or a mechanical penthouse can far exceed the load on the open field, so we map the likely drift lines on the roof plan and check those areas first.

Hail is the other risk. In 2016 central and south Missoula took quarter-size hail and a downpour that outran the storm drains. Events like that raise the question of whether a given roof was hit, and the answer comes from a walk and a core, not from a news report. We document marks, test the suspect areas and keep the dated photos. If the district files a claim, the record is ready, and our hail damage repair scope starts from the same photographs.

A school roof is not finished when the last roll is down. It is finished when the punch list is cleared, the drains are flowing, the flashings are sealed and the photographs are in the file. We walk the roof with the facilities manager, test the drains with water and note every item that still needs attention.

The closeout record lists the membrane, the attachment, the insulation and the date. It goes into the district's roof inventory, along with the next review date. That record is what a board reads at budget time, and it lets the next walk start from a known baseline.
