Roof Cleaning and Repair in Fredericton
Arrange Roof Cleaning and Repair in Fredericton by asking for an inspection and separate written scopes for cleaning and repairs. Describe any leaks before discussing appearance. Check the contractor’s insurance and WorkSafeNB status, then confirm City requirements if the proposed repairs involve significant alterations or exterior changes to a protected building. [1] [2] [3]
Start with the problem you need solved
Tell prospective contractors whether you want to address staining, moss, loose material, overflowing gutters or water entering the house. Include photographs taken from the ground and describe when you first noticed the problem. For a leak, record the indoor location and whether you noticed it during rain or snowmelt. Ask for an assessment of the cause before approving cosmetic work.
Request photographs of the areas the contractor proposes to repair. Have them distinguish cleaning, repairs and any recommended replacement in the estimate. If they recommend replacement, ask what condition makes a repair unsuitable and which parts of the roof they inspected. You can use that explanation when seeking another assessment.
For cleaning, ask the contractor to name the product, application method and proposed pressure, and explain compatibility with your roofing manufacturer’s instructions. Request a plan for protecting plants, managing runoff and handling debris. Agree on the expected appearance at completion and whether the contractor proposes a follow-up visit.
Compare written scopes before comparing totals
Ask each bidder to price the same areas and tasks. Separate roof cleaning, gutter and downspout work, repair labour, materials, access equipment and disposal. Request a total in Canadian dollars with applicable taxes identified. Agree on the deposit, payment stages and the process for approving additional work.
For repairs, ask the contractor to identify the affected roof areas and proposed materials. Specify who will document concealed damage and obtain your approval before expanding the job. Request written warranty terms, including who handles a callback and what work the warranty covers.
Get property-specific written estimates to set your budget. Ask bidders to explain differences in access arrangements, treatment scope and repairs before you compare their totals. Keep optional treatments separate so you can decide which work to approve.
Check insurance and the roof-access plan
WorkSafeNB advises homeowners to check contractor insurance and obtain a clearance certificate to confirm workers compensation standing. Its homeowner guidance distinguishes employers that must carry coverage from smaller employers and solo proprietors for whom coverage can be optional. Ask who will attend the job, whether subcontractors will participate and what coverage applies to those people. [3]
Ask for proof of general liability insurance and discuss coverage with the contractor before work starts. If a solo proprietor has no WorkSafeNB coverage, discuss your insurance expectations instead of assuming that a clearance check and liability policy answer the same question. [3]
WorkSafeNB’s roofing guidance identifies hazards involving ladders, electrical lines, protective equipment and rescue procedures, alongside falls. Ask the contractor to explain safe access, the fall-protection arrangement and emergency rescue planning for your roof. Share known hazards, including electrical hazards or asbestos, before the crew arrives. [3] [4]
Agree on weather conditions and completion records
Fredericton Airport’s published 1991–2020 normals show daily average temperatures declining from 14.2°C in September to 7.7°C in October and 1.7°C in November. Use that seasonal context to ask about temperature limits, drying or curing requirements and postponement arrangements for the proposed products. Check the forecast with the contractor before the visit. [5]
Agree on who will move vehicles and outdoor furniture, where the crew can place equipment and how they will keep people clear of the work area. Ask whether they need water or power access. Keep your own observations at ground level and request photographs of completed roof work.
Before final payment, review the agreed scope, repair photographs, cleanup and written warranty. Record any remaining work and its completion date. For work under a building permit, the City requires the owner to request a final inspection; it closes the permit when that inspection finds no outstanding issues. [1]

Local details that affect your job
Discuss significant alterations with Building Inspections
Fredericton requires building permits for significant alterations to existing buildings. Before approving structural roof work, discuss the proposed scope with Building Inspections at the ground-floor counter at City Hall, 397 Queen Street. The City encourages this discussion before applying so staff can identify required plans or documentation. Describe the proposed cleaning and repairs and ask staff to confirm the requirements for your project. [1]
Check protected status before ordering roofing materials
The City’s Preservation By-law protects the St. Anne’s Point Heritage Preservation Area and other locations throughout Fredericton. The City requires a Certificate of Appropriateness for exterior alterations to protected buildings before issuing a building permit. Submit the certificate application to the Heritage Division before or during the building-permit application. Ask Heritage staff about your address and proposed roof changes before committing to replacement materials. [2]
