Roofing built around how your building earns
A commercial roof is not just shelter - it protects inventory, equipment, tenants and the hours your doors stay open. In the Hillyard historic rail district in NE Spokane, many of the buildings along Market St have been adapted over the decades from their early-1900s origins, which means the roof you have today is often a patchwork of past repairs rather than a single planned system.
We start by understanding what is underneath you, where water is actually going, and how much disruption your operation can tolerate during the work. From there we recommend a system that fits the building and the budget - not the other way around.
Low-slope and flat systems for older Hillyard buildings
Much of Hillyard's commercial stock sits on flat or low-slope decks, and those need different materials than a steep residential roof. Depending on the building we install and service:
- TPO and single-ply membranes - reflective, weldable seams, strong for wide flat expanses
- Modified bitumen - durable multi-layer protection well suited to foot traffic and roof equipment
- Metal and standing seam - long service life where slope and structure allow
- Coatings and restoration - extending a sound deck before a full tear-off is required
Because the older early-1900s homes and converted buildings around the district often hide brittle decking and outdated drainage, we check the substrate before quoting a membrane that assumes a perfect surface.
Drainage, ponding and the NE Spokane climate
Flat roofs in the Inland Northwest live or die by drainage. Heavy snow loads, freeze-thaw cycling and spring melt all push water toward low spots, and ponding on an aging membrane is one of the fastest ways to a sudden interior leak. We map your drains, scuppers and slope, then correct the standing-water issues that shorten a roof's life rather than just patching the symptom.
Ice dams and refreezing at the roof edge are just as hard on commercial parapets as they are on houses, so flashing and edge details get real attention on every Hillyard project we take.
Working around your business hours
A retailer near Market St cannot lose a Saturday, and a service business cannot shut its phones for a week. We sequence commercial work to keep entrances usable, protect storefronts and signage, and stage materials so your customers and staff stay safe. Where a building is occupied by tenants, we coordinate access and notice so nobody is caught off guard.
