How Old Is the Roof, and How Long Has It Got?

A roof that is not leaking looks fine from the driveway. A roof with five years left and a roof with twenty are different purchases, and the gap between them is one of the few condition questions with a fairly knowable answer.

The two questions worth asking

How old is it, and how much service life is left?

Ask the seller for the installation date and any invoice or permit. Ask your home inspector what they observe. Those two answers together get you most of the way, and our home inspection guide covers what an inspector's report does and does not commit to.

An inspector reports visible condition and may offer an opinion on remaining service life. That is a visual assessment rather than a guarantee. A roofing contractor can assess more specifically, which matters when the age is uncertain and the stakes are high.

In a strata, the answer is written down

This is the easier and more consequential version of the question.

A roof is generally common property, so the strata replaces it and every owner pays a share through the reserve fund or a special levy, allocated by unit entitlement. Our window replacement guide covers the same mechanic on a different building element.

The depreciation report should carry the roof's age and its projected replacement. Our depreciation report guide covers how to read a projection schedule.

Then read that projection against the actual reserve balance. The Government of BC's contingency reserve fund page lists roof replacement as an example of what the CRF exists for, so a strata with a roof due and no money set aside has a gap you would be paying into. Since November 1, 2023, stratas must contribute at least 10% of their budgeted annual operating fund to the reserve each year.

Read the council minutes too. A roof project appears in discussion long before it appears as a levy, and our special levies guide covers how it lands.

The insurance angle buyers forget

Roof age is an underwriting input, not only a maintenance question.

In our experience insurers ask about roof age and condition, and an older roof can affect premium or coverage terms. Confirm with your insurance broker on the specific property during your subject period rather than at completion.

Our insurance claim history guide covers how insurers look at a property's record, and our condo insurance guide covers the split between the strata's policy and yours.

If the roof was recently replaced

Good news, with two follow-up questions.

Ask to see the invoice and any permit. Work with documentation is work somebody stands behind, which is the same principle that applies to electrical alterations and unauthorized suites.

In a strata, ask whether the levy that funded the work is fully paid or still being collected in instalments you would inherit. A building with a new roof and a levy outstanding is a different purchase from a building with a new roof and a closed file.

Newer homes and the warranty

On a newer home, part of the 2-5-10 warranty may still be live.

BC Housing's coverage includes 5 years on the building envelope, including unintended water penetration that could cause damage, and 10 years on structure. BC Housing also states that coverage stays with the home rather than the owner, so a newer resale may carry remaining coverage.

Our warranty claim guide covers how to use it and why written notice matters, and the 2-5-10 overview covers the periods.

The Fraser Valley climate factor

Moss and debris are part of owning a roof here, and maintenance affects service life.

Ask what maintenance has been done rather than reading a clean roof as proof of youth. A well-maintained older roof and a neglected newer one are not where buyers assume they are on the timeline.

Drainage is the connected question. Our perimeter drain guide covers where the water goes once the roof has shed it, and in this climate the two systems are worth thinking about together. Our crawlspace moisture guide covers what shows up when drainage fails.

What to do with this

Get the age, get the projection, and price the gap.

If a roof has five years left and replacement is a known figure, that belongs in your budget alongside the purchase rather than arriving as a surprise. Our first-year budget guide covers what new owners underestimate, and a near-term roof is one of the larger items.

If the inspector flags it or the age is genuinely unknown, book a roofing contractor during your subject period. Book early, because specialist visits take longer to schedule than a general inspection, and our subject removal guide covers protecting that time.

We are agents rather than inspectors or roofers, and none of this is a technical assessment. A qualified roofing contractor, your inspector, and your insurance broker are the right sources for a specific property.

Key takeaways

• Ask the seller for the installation date and invoice, and ask your inspector what they observe.
• In a strata, the roof is generally common property and the depreciation report should carry its projected replacement.
• Read the projection against the reserve balance. The Government of BC names roof replacement as a CRF purpose.
• Roof age can affect insurance premium or coverage terms, so ask your broker during the subject period.
• On a recently replaced roof, ask for the invoice and whether any funding levy is fully paid.

Frequently Asked Questions

How do I find out how old a roof is?

You find out a roof's age by asking the seller for the installation date and any invoice or permit, and by asking your home inspector what they observe about visible condition. Those two answers together get you most of the way to a real picture. On a strata, the question is easier and more consequential, because the depreciation report should carry the roof's age and its projected replacement date, and you can read that projection against the reserve fund balance to see whether money is actually set aside for it.

Does a home inspector tell me how long the roof has left?

A home inspector reports on visible condition and may offer an opinion on the roof's remaining service life, but that opinion is a visual assessment rather than a guarantee of how many years are left. A roofing contractor can assess the roof more specifically, which matters when the inspector flags a concern or the age is genuinely uncertain and the stakes are high. Book a roofing contractor early during your subject period, since specialist visits take longer to schedule than a general home inspection.

Does roof age affect my insurance?

Roof age is both a maintenance question and an insurance question. In our experience insurers ask about roof age and condition, and an older roof can raise your premium or change your coverage terms on a specific property. Confirm this with your insurance broker during your subject period, well before completion, so any premium increase or coverage condition is something you can plan around before you own the home.

In a strata, who pays to replace the roof?

In a strata, the roof is usually common property, so the strata corporation replaces it. Every owner pays a share through the contingency reserve fund or through a special levy, allocated by unit entitlement, which is the same funding mechanic that applies to other shared building elements such as window replacement. The Government of BC lists roof replacement as an example of what a contingency reserve fund exists for, so check the depreciation report and the reserve balance before you buy.

Where does a strata roof project appear before it happens?

A strata roof project appears first in the depreciation report's projection schedule, which should carry the roof's age and its projected replacement date, and then in the council minutes long before it becomes a special levy. The Government of BC lists roof replacement as an example of what a contingency reserve fund is for, so read the projection against the actual reserve balance. A strata with a roof due soon and no money set aside has a gap that future owners, including you, would be paying into.

Is a new roof a reason to pay more?

A recently replaced roof removes a known future cost, which has real value, so it can be a reasonable factor in what you are willing to pay. Ask to see the invoice and any permit for the work, since documentation is work somebody stands behind. On a strata, also ask whether the levy that funded the replacement is fully paid or still being collected in instalments you would inherit, because a new roof with an outstanding levy is a different purchase from a new roof with a closed file.

What should I look for on a townhouse?

On a townhouse, look for whether the roof is common property, what the depreciation report says about its age and projected replacement, and whether the reserve fund is actually funded against that projected replacement date. That combination is the whole question in a strata. Read the council minutes too, since a roof project appears in discussion long before it appears as a special levy, and ask whether any existing levy that funded past roof work is fully paid or still being collected from owners.

Does moss matter in the Fraser Valley?

Moss matters in the Fraser Valley, since moss and debris are part of owning a roof in this climate, and how well it has been maintained affects the roof's remaining service life. Ask what maintenance has been done rather than treating a clean roof as proof of a younger age, because a well-maintained older roof and a neglected newer one are not always where buyers assume they are on the timeline. Drainage is the connected question worth asking about at the same time, since the two systems work together once the roof sheds water.

Should I get a roofing contractor during my subject period?

Yes, if your home inspector flags the roof or the age is genuinely uncertain and the stakes are high, book a roofing contractor during your subject period for a more specific assessment than a general home inspection provides. Book early, because specialist visits take longer to arrange than the general inspection, and your subject period has a fixed end date. If a roof has five years of service life left, get that figure into your budget alongside the purchase price rather than letting it arrive as a surprise later.

What is the biggest mistake buyers make here?

The biggest mistake is treating a roof with five years of service life left the same as one with twenty, because both can look fine from the driveway while they are dry. The difference is a future replacement bill, and the information is usually available on request: from the seller's invoice, the home inspector's report, or, on a strata, the depreciation report and reserve fund balance. Knowing the age and the projection lets you account for the replacement cost in your offer.
