How Old Is Too Old to Rejuvenate a Roof?

What matters

Condition Beats Age

There's no hard cutoff age. Condition decides, and the sweet spot for rejuvenation is roughly 10 to 20 years old. Two Calgary roofs installed the same summer can be worlds apart by year 15. Sun exposure, slope direction, attic ventilation and hail history all pull the oils out of asphalt shingles at different speeds. Chinook freeze-thaw cycles are hard on south-facing slopes in particular.

So we don't quote from your roof's birth year. We look at granule loss, curling shingles, brittleness, and the state of valleys and flashings.

★★★★★ 5.0 on Google, partly because we say no when we should.

10 to 20 years

The Sweet Spot

Here's what qualifying roofs tend to have in common.

• Shingles still lie flat, with only early curling at most
• Granules mostly intact, no bald patches of exposed mat
• Valleys, flashings and vents in sound shape

Age then picks the tier. Younger roofs in good shape suit Fortify, our 15-year treatment. Mid-life roofs with early wear suit Revive. Older roofs that still qualify often suit NuRoof Bio-Boost, a 5-year option that buys time before a bigger decision.

The honest part

When We Say No

We regularly tell homeowners no. A spray can't rescue a roof that's structurally done, and we won't sell you one. These are the usual disqualifiers.

• Widespread cracking across multiple slopes
• Exposed mat, where the granules are already gone
• Failed valleys or active leaks into the attic

Why is a no good for you? Because you get photos of your own roof and an honest read, free. That beats spending $3,000 on a roof that needed replacing, or $15,000 on one that didn't.
