Why Warranties Are the Most Misunderstood Part of Strata Roofing

After completing over 500 roofs across the Fraser Valley, Johnny and I have sat in dozens of strata council meetings where the warranty conversation goes sideways. A council approves a $200,000 re-roof based partly on a "50-year warranty" without realizing that the full-coverage window is only 10 years. Or they skip annual inspections for three seasons and then discover their entire warranty is void when a leak appears.

Before we started Dads Roofing in 2021, we spent years as Red Seal Journeyman Boilermakers. In boilermaking, warranty compliance is not optional — pressure vessels and piping systems carry legal liability that can shut down an entire plant. That mindset carried straight into our roofing work. Every roof we install has documented nailing patterns, photographed flashing details, and registered manufacturer warranties. We treat every strata roof like a system that needs to be defensible on paper, not just watertight overhead.

The Two Warranties Every Strata Roof Carries

Every professionally installed strata roof should come with two separate warranties. Confusing them is where most councils get into trouble.

Workmanship Warranty: The Contractor's Promise

This is the contractor's guarantee that they installed everything correctly. If a leak appears because step flashing was improperly lapped, or shingles were nailed too high, or ridge ventilation was undersized, the workmanship warranty covers the repair at no cost to the strata corporation.

What falls under workmanship coverage:

• Nailing errors — insufficient fasteners, nails placed outside the manufacturer's nailing zone, or overdriven nails that crack the shingle mat
• Flashing deficiencies — valley flashing installed without proper overlap, step flashing that does not extend behind the wall cladding, or chimney counter-flashing that was not properly embedded
• Ventilation miscalculations — intake and exhaust out of balance, causing moisture buildup that accelerates shingle deterioration from underneath
• Underlayment gaps — ice and water shield missing from eave edges, valleys, or around penetrations where BC code requires it
• Leaks from any installation defect — including resulting interior damage to ceilings, insulation, or drywall

Standard workmanship warranty terms in BC:

• Budget contractors: 2 to 5 years
• Established contractors: 5 to 10 years
• What we provide: 10-year workmanship warranty on every strata project, documented and signed at project completion

Material Warranty: The Manufacturer's Promise

This warranty comes from the company that made the shingles, underlayment, or metal panels. It covers manufacturing defects — products that fail before they should because something went wrong at the factory, not on your roof.

What falls under material coverage:

• Premature granule loss — shingles shedding their protective surface coating far earlier than the product's rated lifespan
• Cracking or splitting — shingle mats that fracture due to defective asphalt formulation, not normal thermal cycling
• Delamination — layered products separating because of adhesive failure during manufacturing
• Blistering — trapped moisture in the shingle from the factory process causing raised bubbles that pop and expose the mat

Common material warranty durations:

• 3-tab shingles: 20 to 25 years limited
• Architectural shingles: 30 to 50 years limited (full coverage typically only the first 10 to 15 years)
• Premium designer shingles: "Lifetime" limited (realistically 40 to 60 years, prorated after the initial period)
• Standing seam metal: 40 to 50 years on the substrate, 25 to 35 years on the paint finish

The "Limited Warranty" Trap That Costs Strata Councils Thousands

Johnny and I have watched council members' faces fall when they realize what "limited" actually means. Here is the reality behind the marketing language.

A "50-year limited warranty" does not mean the manufacturer will replace your roof for free anytime in the next 50 years. It typically works like this:

• Years 1 through 10: Full replacement coverage if a manufacturing defect is confirmed. The manufacturer supplies new materials at no charge.
• Years 11 through 50: Prorated coverage. The manufacturer pays a declining percentage based on how old the roof is. By year 30, the strata might receive only 40 percent of the replacement material cost.
• Labor is almost never included after the first 5 to 10 years, even on "enhanced" warranties. The strata pays for tear-off and reinstallation.

"Lifetime" warranties are even more misleading. They are typically capped at 50 or 60 years, they are non-transferable to new building owners in many cases, and the prorated schedule kicks in just as aggressively.

BC Strata Property Act and Your Warranty Obligations

The Strata Property Act does not specify minimum warranty lengths for roofing work, but it creates legal obligations that make warranties critical for council members.

• Duty of care: Section 31 requires council to act honestly and in good faith, exercising the care, diligence, and skill of a reasonably prudent person. Accepting a roofing contract without adequate warranty documentation could be considered a breach of this duty.
• Depreciation Reports: BC law requires most strata corporations to obtain Depreciation Reports. These reports must include the expected remaining life of the roof and projected replacement costs. Warranty documentation directly informs these calculations.
• Record keeping: Section 35 requires the strata corporation to keep records including contracts and warranty documents. Losing warranty paperwork is not just inconvenient — it is a failure of legal obligation.

Seven Things That Will Void Your Strata Roof Warranty

Over five years of strata work, we have seen warranties denied for every one of these reasons. Each one was preventable.

1. Skipping annual inspections. Most manufacturer warranties require documented annual inspections. No inspection records means no proof of maintenance, which means a denied claim.
2. Letting moss grow unchecked. In the Fraser Valley's wet climate, moss can establish itself in a single season. Left for two or three years, it lifts shingle edges, holds moisture against the mat, and voids both workmanship and material coverage.
3. Clogged gutters and downspouts. Water backing up under the eave edge causes ice damming in winter and fascia rot year-round. Both manufacturers and contractors exclude damage caused by drainage neglect.
4. Unauthorized modifications. Satellite dish brackets screwed through the shingle surface, solar panel mounts installed without proper flashing, or HVAC penetrations cut by other trades all void the warranty in the affected area — and sometimes the entire roof.
5. Repairs by unlicensed individuals. A strata maintenance worker patching a leak with roofing cement does not count as a professional repair. If that patch fails and causes further damage, the warranty claim will be denied.
6. Failure to register the material warranty. Many manufacturers require online registration within 30 to 60 days of installation. Miss that window and the warranty downgrades to a shorter, non-transferable version.
7. Improper attic ventilation left unaddressed. If the building's ventilation is insufficient and the council does not correct it, moisture damage from condensation is excluded from both warranty types.

How We Handle Warranty Claims at Dads Roofing

Our process is straightforward because we document everything during installation. When a strata council calls with a concern, here is what happens:

1. Inspection within 48 hours. Kory or Johnny goes to the building personally. We do not send a subcontractor to evaluate our own work.
2. Root cause determination. We figure out whether the issue is workmanship (our responsibility), material (manufacturer's responsibility), or maintenance-related (the strata's responsibility).
3. Workmanship issues get fixed immediately. If the problem traces back to our installation, we schedule the repair and complete it at no charge. No arguments, no delays.
4. Material claims get filed on your behalf. If we identify a manufacturing defect, we contact the manufacturer, submit the required documentation including our installation photos, and manage the claim process. We have relationships with every major shingle manufacturer operating in BC.
5. Written report to council. Every warranty inspection results in a written summary that the council can file with their strata records. This protects the council and satisfies their record-keeping obligations under the Strata Property Act.

What Happens When the Contractor Goes Out of Business?

This is the risk nobody wants to talk about, but it is real. Roofing companies in BC have a high turnover rate. If the contractor who installed your strata roof closes shop in year three of a 10-year workmanship warranty, that warranty is gone.

The material warranty from the manufacturer remains valid regardless of what happens to the contractor, but the workmanship coverage evaporates. This is why choosing a stable, established contractor matters as much as the warranty document itself.

Steps to protect against contractor failure:

• Verify the contractor carries adequate liability insurance and WorkSafeBC coverage
• Check their business registration history with BC Registry Services
• Ask how many strata projects they have completed in the past three years
• Request references from strata corporations, not just residential homeowners
• Consider contractors who offer manufacturer-backed extended warranties, which survive even if the installing company closes

Warranty Documentation Checklist for Strata Councils

At project completion, your strata corporation should have all of the following on file. We provide every one of these documents as part of our standard handover package.

• Signed workmanship warranty with coverage period, scope, and exclusions clearly stated
• Manufacturer warranty certificate with registration confirmation number
• Complete material specifications (product name, color, lot numbers if available)
• Installation photographs documenting nailing patterns, flashing details, underlayment coverage, and ventilation configuration
• Final inspection report with measurements and observations
• Maintenance schedule required to keep both warranties valid
• Contractor's business license, insurance certificate, and WorkSafeBC registration

Maintaining Warranty Coverage Year After Year

A warranty is only as good as your maintenance record. Here is the annual routine we recommend to every strata council we work with:

• Spring inspection (March or April): Check for winter damage, ice dam effects, flashing integrity, and debris accumulation. Document with dated photographs.
• Gutter cleaning (May and November): Clear all gutters, downspouts, and drainage outlets. Blocked drainage is the number one preventable cause of warranty-voiding damage.
• Moss treatment (every 2 to 3 years): Apply zinc-based moss treatment or schedule professional removal. In the Fraser Valley, moss grows aggressively — staying ahead of it is not optional.
• Fall inspection (October): Verify the roof is ready for BC's wet season. Check sealant around penetrations, confirm ventilation is unobstructed, and trim any branches within two meters of the roof surface.
• Keep every record. Inspection reports, maintenance invoices, and photographs should be filed with the strata corporation's records. This documentation is your proof of compliance if a warranty claim is ever questioned.
