A multi-building roof replacement is not five single-family roofs in a row. The scheduling, communication, code compliance, and budget complexity scale faster than the building count.
If you’re a property manager or owner planning a portfolio reroof in Snohomish County, this is the playbook we walk you through.
Start 12 Months Before You Want Work to Begin
A residential roof replacement can be scoped, contracted, and executed in 4 to 8 weeks. A multifamily portfolio takes 3 to 4x longer, almost entirely because of:
- Bidding multiple qualified contractors and getting comparable scopes.
- Board or ownership approval cycles.
- Tenant notification windows (often 60-90 days for full-tenant-occupancy buildings).
- Material lead times for high-volume orders.
- Permitting across multiple buildings.
If you want work in the dry season (June-September), start the planning conversation in the prior fall.
The Scoping Conversation
The first contractor visit isn’t an estimate. It’s a scoping conversation. Plan for 90 minutes per building covering:
Per-building roof condition
Each building gets its own inspection with drone, walk, and attic. Some buildings in a portfolio will need full replacement, some will need a 5-year hold-and-monitor plan. We’ll tell you which.
Building-by-building budget tier
Not every building needs the same material. We typically tier:
- Tier 1 (newest, best condition): Full premium replacement.
- Tier 2 (mid-life): Replacement with mid-tier material.
- Tier 3 (oldest, deferred): Major repair plan, replacement in 3-5 years.
This protects your capital budget and avoids over-spending on buildings that are scheduled for major renovation or sale.
Code compliance review
Multi-family buildings often have ventilation requirements, fire-rating requirements, and energy code requirements that single-family doesn’t. Our scope includes verifying current code compliance and budgeting upgrades where needed.
Tenant occupancy considerations
Vacant buildings get scheduled differently than fully-occupied buildings. Buildings with elderly residents or daycare services have different work-hour constraints. Buildings with rooftop equipment (HVAC, satellite, communications) need shut-down coordination.
The Bidding Process
Bid the project to 3 contractors who specialize in multifamily. Avoid contractors who do mostly single-family residential and are scaling up. The project management complexity is different.
What to require in every bid:
- Per-building line items so you can see the cost differential between buildings.
- Material spec sheets for every product (no “comparable to” language).
- Workmanship warranty length explicitly stated.
- Tenant communication plan included.
- Insurance certificates and bonds before contract signing.
- Project timeline by building with start and completion dates.
- Change order policy for hidden conditions (rotted decking, surprises during tear-off).
If a contractor can’t provide all of these in writing, they aren’t ready for portfolio-scale work.
Tenant Communication Plan
The most operationally complex part of multi-family roofing is tenant communication. Our standard plan:
90 days out
Initial notification to all building tenants. Letter from property management explaining:
- Replacement is happening.
- Approximate building schedule (specific date will follow).
- Expected duration per building.
- What to expect (noise, debris, parking impact).
- Who to contact with questions.
30 days out
Building-specific schedule confirmation. Tenants know which week their building is scheduled.
7 days out
Detailed notification:
- Exact start date.
- Daily start and end times.
- Vehicle moving requests (some areas need to be cleared).
- Pet considerations.
- Outdoor item considerations (patio furniture, plants on patios).
Day before
Final reminder. Phone numbers for the project site manager.
During work
Daily updates posted at building entrances. Site manager reachable by phone.
We provide all of the templates, signage, and notification materials. You provide the tenant list.
Scheduling
Multifamily reroofs in Snohomish County are typically scheduled:
- Single building (4-12 units): 5-10 working days.
- Two-to-three buildings simultaneously: 3-6 weeks.
- Larger portfolios: Phased over a season, with 1-2 buildings active at a time.
We don’t typically run more than 2 buildings simultaneously per crew. Quality control degrades faster than the cost savings justify.
Budget Surprises to Plan For
Three categories of surprise that consistently appear:
Hidden deck rot
When tear-off exposes the decking, some sections are usually rotted. We document before replacement and quote the change order before proceeding. Budget 5-15% of project cost for likely rot repair.
Ventilation upgrades
Older multifamily buildings often have inadequate attic or roof ventilation. Code-compliant ventilation upgrades typically add $300-$1,200 per unit.
Gutter and downspout work
Many multifamily buildings have undersized or aged gutters. Replacing gutters during the reroof is significantly cheaper than doing it separately. Budget $9-$16 per linear foot of gutter.
Specialty flashing for skylights, roof equipment, transitions
Buildings with rooftop HVAC, communications equipment, or unusual penetrations often need custom flashing. Budget 2-5% of project cost.
A good contractor will identify likely surprises during scoping so you can budget for them. A bad contractor will surprise you mid-project.
Insurance and Liability
Verify before signing:
- General liability: Minimum $1M per occurrence, $2M aggregate.
- Workers’ compensation: Current and verifiable.
- Auto: Includes vehicles used on your property.
- Property damage: Specific coverage for damage during work.
- Additional insured: Your ownership entity should be named additional insured for the duration of the project.
Get certificates from the carrier directly, not from the contractor. We’ll provide ours on request.
Payment Schedule
Standard structure for multifamily projects:
- 10% down at contract signing.
- 30% at material delivery.
- 30% at midpoint (typically halfway through buildings).
- 25% at substantial completion.
- 5% retention released after final walkthrough and warranty paperwork.
Avoid contractors who request more than 25% upfront. It’s a bad-faith pattern.
What to Expect From Us
Multifamily projects get a dedicated Site Manager assigned to the project for the full duration. Same person, every building, full attention. Not a rotating foreman.
You get weekly project updates with progress photos. Daily updates if any building is showing any complication. Direct phone access to Dylan if anything escalates.
If you’re a property manager planning a portfolio reroof in Snohomish County and want a real scoping conversation, reach out. We’ll walk every building, deliver a written master scope with per-building breakdowns, and give you a realistic timeline.
