Quick Summary
Hiring roofers for condo buildings requires defining your project scope, verifying contractor insurance and warranties, comparing detailed bids using the same specifications, and planning for resident communication and minimal disruption. Success depends on asking the right questions upfront, checking references for condo experience, and understanding timelines before committing to a contractor.
- Get proof of liability and workers’ compensation insurance and call the insurer to verify coverage is active.
- Issue the same written bid specification to every contractor so quotes are comparable on identical line items.
- Ask contractors for at least three recent condo building project references and call them to verify quality and timeline adherence.
- Phase work across multiple buildings to keep some fully weathertight while others are open and to spread costs.
- Send residents a notice 2-4 weeks before work starts explaining what will happen, when, and how long it will last.

Why Hiring the Right Roofer Matters for Condo Buildings
A condo building’s roof is its most critical defense against weather. When it fails, water damage spreads fast, repair costs balloon, and the board faces liability.
Hiring roofers for condo buildings isn’t like hiring for a single home.
Smart hiring protects buildings for decades; rushed choices create problems two winters later. The difference is preparation and asking the right questions upfront.
This guide covers seven steps to hire the right roofing contractor: what to ask, what to verify, and how to evaluate competing bids.
Step 1: Define Your Roofing Needs and Project Scope
Before you call a single roofing contractor, know exactly what you need.
Is your roof leaking? Each situation demands different expertise. Learn about roofing material options for your commercial roof replacement to understand which systems work best for your building.
Walk your roof with a professional inspector if you haven’t already. Document what you see:
- Current roofing material (shingles, membrane, metal)
- Age of the roof
- Visible damage or wear
- Drainage issues
- Structural concerns
Understand your building’s constraints.
Alberta’s building code standards for residential roofing outline minimum requirements for your province. Know these before you hire.
Get clarity on scope: full replacement or patching, material upgrades, insulation or ventilation work. A vague scope invites cost overruns and disputes.
Commercial roofing material durability comparisons can help you understand which materials suit Alberta’s freeze-thaw cycles and heavy snow loads.
Document everything in writing. Your scope statement becomes part of your contract. It prevents misunderstandings later.
Step 2: Ask the Right Roofing Contractor Questions
Now you’re ready to contact roofing contractors. Not all of them are right for condo buildings.
Start with these core questions:
Experience with condo buildings. Ask directly: “How many condo building roofing projects have you completed?” Get specifics: how many units, what materials, how resident coordination was handled. Ask how the contractor would manage noise, tenant scheduling, and coordination for your building.
Insurance. Ask for proof of liability insurance. Call the insurer to verify coverage is active.
Warranty details. What does the contractor guarantee? For how long? Does the warranty cover labor and materials?
Schedule and timeline. When can they start? How long will the project take?
Subcontractors. Will they use their own crew or hire subcontractors? If subcontractors, who are they?
References. Ask for at least three recent condo building projects and call them. Ask about quality, timeline adherence, and how resident disruption was handled.

Step 3: Verify Roofing Contractor Insurance and Warranties
Insurance protects you. Warranties protect your investment.
Liability insurance. Call the insurer directly to confirm the policy is active and covers roofing work.
Workers’ compensation insurance. Verify coverage with the insurer.
Warranty types. There are two warranties to understand:
Make sure any warranty is in writing and specifies what’s covered.
Warranty gaps. Read the fine print.
Get the warranty in writing before work begins. Have your lawyer review it if the project is large.
Bonding. For larger projects, ask if the contractor carries a performance bond.
Step 4: Evaluate Quotes Using a Commercial Roofing Quote Checklist
You’ve narrowed your list. Now you have three to five quotes from roofing contractors.
Review each bid for exclusions, allowances, and the proposed membrane system.
Build a bid specification before you compare prices
Issue the same written scope to every bidder. When every contractor prices the same line items, quotes become comparable. When they don’t, you’re comparing apples to re-roofs.
A reusable condo roofing bid specification should cover:
- Roof areas by building and section. List each roof area, approximate square footage, and deck type (steel, concrete, wood). Multi-building projects should be priced per building so the board can phase work.
- Existing assembly and tear-off. Specify whether the existing membrane and insulation are removed to the deck or overlaid, and who pays for disposal and dumpster placement.
- Materials and system. Name the membrane type (for example, modified bitumen, EPDM, or TPO), thickness, insulation R-value, cover board, and fastener schedule. Avoid “or equal” language unless you define what equal means.
- Drainage. Include drain count, strainer replacement, scupper work, and slope corrections. Ponding water is a common post-project complaint; require the contractor to address it in the bid.
- Flashing and penetrations. List parapet walls, roof hatches, HVAC curbs, vents, and skylights that need flashing or replacement.
- Access and hoisting. State how materials reach the roof (crane, hoist, stair carry) and who is responsible for permits, street occupancy, and parking.
- Cleanup and debris removal. Specify daily cleanup, magnet sweeps for nails, and disposal of old materials.
- Alternates. Ask each bidder to price optional items separately, such as upgraded insulation, a reflective coating, or a maintenance plan, so the board can see the cost of each upgrade.
- Schedule and phasing. Require a start date, duration per building, and weather contingency plan.
- Warranty and closeout. Require manufacturer and workmanship warranty terms, as-built drawings, and a closeout package.
Compare quotes on the same criteria
Once bids are in, score them against a consistent checklist. A simple weighted matrix works well:
| Criteria | Weight | What to look for |
|---|---|---|
| Scope completeness | High | Every line item in your specification is priced, not excluded |
| Condo experience | High | Recent multi-unit projects with references |
| Insurance and bonding | High | Verified liability, workers’ compensation, and bond capacity |
| Warranty terms | Medium | Manufacturer and workmanship coverage in writing |
| Schedule and phasing | Medium | Realistic dates and a weather plan |
| Price | Medium | Total cost including alternates and allowances |
| Resident logistics | Medium | Written communication and access plan |
Price should be one column, not the deciding column. A bid that includes full tear-off, new insulation, and a workmanship warranty may have a different lifecycle cost.
Watch for these red flags in quotes
- Vague descriptions of work or “as required” line items
- No timeline or an unrealistic one
- No warranty details or warranty that excludes labor
- Prices that seem too low compared with the field
- Refusal to provide references or certificates of insurance
- Allowances that shift risk to the board
- Payment terms that front-load deposits before materials arrive
Ask each contractor to walk through their quote
Have each bidder present their proposal to the board. Ask what is and isn’t included, roof removal and disposal, underlayment, flashing repair, drain strainers, and what the change-order process is if hidden damage is found.
Get everything in writing. Verbal promises disappear when disputes arise. Document the board’s decision, scoring matrix, and reasons for the award in the meeting minutes to protect the board if an owner later challenges the choice.
Send the same bid specification to every contractor and require them to price every line. Bids that skip line items are not cheaper; they are incomplete.
For a systematic approach to vetting local contractors, learn the key steps to finding reliable roofers.
Step 5: Understand the Roof Replacement Project Timeline
A roof replacement isn’t quick. Understand the timeline before you commit, and plan it around the buildings and the people underneath them.
The timeline for a flat roof replacement depends on the building and weather. Plan for possible weather delays.
Phase the work across multiple buildings
If your condo corporation has more than one building or roof section, don’t treat the project as one continuous job. Phasing lets the board:
- Keep some buildings fully weathertight while others are opened
- Spread cost across budget years
- Reduce the number of residents affected at once
- Test the contractor’s workmanship on one building before committing to the rest
Buildings can be sequenced by condition, with a written hold point after each building. At each hold point the board inspects the completed roof and confirms the next building can proceed.
Understand each phase
Preparation phase. The contractor inspects the roof, confirms deck conditions, orders materials, and submits permits. The board should confirm staging areas, hoisting plans, and parking impacts before this phase ends.
Removal phase. The old roof comes off. The contractor should have a plan to protect stairwells, elevators, and corridors.
Installation phase. New materials go down. Ask how the contractor will protect exposed areas during the work.
Inspection and closeout. Agree on inspection and closeout requirements before work begins.
Plan for weather contingencies
Weather is the biggest schedule risk. Ask each contractor:
- How many weather days have you built into the schedule?
- How do you protect open roof areas overnight and on weekends?
- At what temperature or wind speed do you stop work?
- If a delay pushes the project into a colder month, what changes?
Get the answers in writing. Ask how the contractor plans for weather-related delays.
Coordinate inspections and handover
Ask whether the proposed roofing system has inspection requirements and what documentation will be provided. At handover, collect:
- Manufacturer and workmanship warranties
- As-built drawings and photographs
- Maintenance recommendations and a suggested inspection schedule
- A list of any outstanding deficiencies and the date they will be corrected
Build a resident communication calendar around the schedule
Plan resident notices around each phase and each building. Let tenants know when their building will be worked on, how long it will last, and what to expect. A written schedule with start dates, expected completion, hold points, and contingency dates protects both the board and the contractor.
Do not let the contractor open more roof area than can be made weathertight before the end of the workday. Exposed decking is the most common cause of interior water damage during a re-roof.
Ask how the contractor will coordinate work around occupied buildings, phase the project, protect exposed areas, and address resident concerns and weather planning.
Step 6: Plan for Resident Communication and Minimal Disruption
A communication plan can help residents know what to expect during the project.
Set noise expectations. Tell residents when work will happen and ask the contractor about expected noise and work hours.
Manage access. Contractors need stairwells, elevators, and common areas to reach the roof.
Handle complaints. Assign one board member as the point of contact for resident complaints. Respond quickly.
Document everything. Take photos of the existing roof before work starts. Document progress during the project.
