Apartment, townhome, and condominium re-roofing.
The multi-family division installs and replaces roofs on apartment complexes, townhome clusters, and condominium associations across the Portland metro and the Willamette Valley. It is the most operationally-demanding division at Cascade — the work is not technically harder than residential, but the coordination is. Astrid runs it. The commercial-side estimating team scopes it. A senior residential foreman manages the on-roof crews.
The Cascade multi-family offer is turnkey. One scoping site visit. One phased schedule. One single-point-of-contact in Astrid or her assistant Naomi. One invoice cadence. One warranty document. One set of resident notification letters drafted on your property management letterhead. Your residents see one Cascade crew, in one set of slate-gray work shirts, in one well-organized staging area, for the duration of the project.
Four steps. Twelve weeks. One point of contact.
Scoping site visit
Astrid plus a senior estimator walks every roof on the property. We pull a drone aerial of the complex. We photograph the substrate of each building. We document existing flashings and ventilation. The scope is delivered as a single spreadsheet with a per-building line item.
Phased schedule
One building per week is the typical cadence for four-to-eight-unit apartment buildings. Smaller townhome clusters can run two buildings per week. We avoid the rain season (November through March) for all asphalt installations; standing-seam can run year-round.
Resident notification letters
Cascade drafts the resident letters on your property management letterhead at least fourteen days before each building’s work begins. We post laminated yard signs at each building entrance the week of the work. We provide the property manager with a daily check-in number that goes to the foreman directly.
Installation in one- to two-building chunks
A single Cascade crew (typically six installers plus a foreman) is on-property for the duration. We never tear off more than we can dry-in the same day. Magnetic sweep every evening. Final walkthrough with the property manager at the end of each building.
Three case studies.

Will my residents have to relocate during the work?
No. We work in phased single-building chunks, never tear off more than we can dry-in the same day, and clean the parking lot every evening with a magnetic sweep. Residents stay in their units. We schedule particularly noisy work (tear-off on the first day of each building) to start at eight rather than seven, and we coordinate with the property manager around any tenants who have noted shift-work schedules.
How do you handle resident notification?
We draft the resident notification letters on your property management letterhead at least fourteen days before each building’s work begins. We post laminated yard signs at each building entrance the week of the work. We provide the property manager with a daily check-in number that goes to the on-property foreman directly — not to the Cascade main office.
What’s the typical multi-family schedule?
Typically one building per week for asphalt re-roofs of four-to-eight-unit buildings. Smaller townhome clusters can run two buildings per week. We work April through October on asphalt to avoid the heavy rain season; standing-seam can run year-round but is rarely the spec on multi-family work.
Do you handle the HOA approval paperwork?
Yes. Astrid drafts the HOA board memo, the material spec sheet, and the architectural review committee submission. We attend the board meeting if the HOA requests it — usually one of us, sometimes both Astrid and the foreman who will run the project.
Single invoice or per-building invoicing?
Single invoice cadence by default — typically thirty-three percent at material order, thirty-three percent at the start of installation on building one, and the remainder on completion of the last building. Per-building invoicing on request, at no additional charge. Most property managers prefer the single cadence; HOAs sometimes prefer the per-building model for reserve-account accounting.
