Should a 20 Year Old Roof Be Replaced?

Twenty years is the age when most Connecticut homeowners start asking the question. Sometimes the honest answer is replace. Sometimes a $400 repair buys you years. Here is how to tell which one your roof is.

Why 20 years is the turning point in Connecticut

Most architectural shingle roofs are rated for 25 to 30 years, but Connecticut weather works faster than the brochure. Our roofs cycle through freeze and thaw dozens of times each winter, carry snow loads, and take nor'easter winds. By year 20, granule loss and brittle shingles are normal here even on a roof that was installed well.

Signs that say replace

Granules collecting in your gutters and bare, shiny patches on the shingles
Curling or cupping shingle edges across multiple slopes
More than one leak, or a leak that comes back after being fixed
Sagging lines along the ridge or planes, which point to decking problems underneath
Neighbors with same-age houses are replacing theirs, since whole streets tend to age together

Signs a repair still makes sense

The damage is isolated: a few wind-lifted shingles, one failed flashing, one small leak
The rest of the roof still holds granules and lies flat
The decking is sound, with no soft spots or stains in the attic

Our rule of thumb, and we say it even when it means a smaller job for us: under 15 years old with isolated damage, repair it. Over 20 with widespread wear, replacement is the better investment, because patching a failing roof just spreads the cost out and adds interior damage along the way. In between, it depends on what the inspection finds. More on that math in repair vs replacement.

What each path costs

Small CT roof repairs run $400 to $600 with a 1-year leak-proof warranty; bigger repairs run $800 to $1,300. A typical CT roof leak repair costs $700 to $3,000 with a $900 median, per Angi 2026. A full replacement runs $9,000 to $18,000 depending on size, pitch, and material, and comes with our in-house 20-year leak-proof warranty. Full pricing detail is on our repair cost page.
