When is a 1979 Stow roof due for replacement?

The median house in Stow was built in about 1979. In 2026 that house is 47 years old. No asphalt shingle roof lasts 47 years, so the question is never whether a 1979 roof has been replaced. The question is how many times, when, and how. The answer tells you whether your roof is due now. A free roof inspection in Stow settles it with photos, but you can narrow it down yourself first.

What is the roof timeline of a 1979 Stow house?

The first roof was almost certainly a 3-tab shingle. In the Midwest those last 15 to 20 years, so the first replacement fell between about 1994 and 1999. From there, a house took one of three paths.

Path one: a second 3-tab roof

If the 1990s replacement was another 3-tab, it wore out between roughly 2009 and 2019. A house on this path is on its third roof today. That roof is somewhere from 7 to 17 years old and, if it is an architectural shingle, has a good stretch ahead of it.

Path two: an early architectural roof

Architectural shingles were becoming common in the late 1990s. They typically last 25 to 30 years. A second roof of that kind, laid in 1997, reaches 29 years old in 2026. This is the house that is due now. It may not be leaking yet. It is simply at the end of its span.

Path three: an overlay

Some owners had the second roof laid over the first to save the cost of a tear-off. An overlay tends to age faster than a roof on bare deck, because the shingles sit on an uneven, heat-holding base. It also leaves two layers. The model code that Ohio's residential code is based on allows no more than two, so the next roof on that house has to start with a full strip to the wood.

How can you tell which roof you have?

• Check your papers. A seller's disclosure or closing file often gives the roof's age at the time you bought.
• Ask the city. Roofing is on Stow's list of permit work, so the Building Department at 3760 Darrow Road may hold a record of a past re-roof at your address.
• Look at the rake edge. From a ladder at the gable end you can see the shingle edges in profile. Two distinct stacks mean two layers.
• Look at the pattern. Flat, even rows with slots every foot are 3-tabs. A varied, shadowed surface is architectural.

Which signs matter more than age?

Age sets the odds. Condition decides. These are the signs a roof is finishing up, in rough order of seriousness:

• Granules collecting at the bottom of the downspouts, like coarse black sand.
• Edges curling upward or tabs cupping in the middle.
• Bald patches where the dark mat shows through.
• Ridge caps that have cracked across the bend.
• A dark worn stripe down the middle of a valley.
• Stains on the underside of the deck when you look up in the attic.
• A soft or springy feel underfoot.

One of these on a 12-year-old roof is a repair. Several of them on a 28-year-old roof are a verdict.

What does Stow's weather add to the wear?

Two things work on a Stow roof that published lifespans do not fully count. The first is the secondary snowbelt. Snow sits on the roof longer here than it does an hour south, and each thaw and refreeze flexes the shingles and tests the eaves. The second is shade. Stow has been a Tree City USA community for more than forty years, and the maples planted beside a 1979 house are now mature. The slope under them stays damp and grows moss, and it can be five years older in condition than the sunny slope on the same house.

So when you judge your roof, judge the worst slope. That is the one that will leak first.

Should you repair it, watch it or replace it?

That is the exact question the inspection answers. The owner inspects the roof himself and sends a photo report the same day with one of three ratings.

• Good: nothing to do. Most third roofs on path one land here.
• Watch: some wear, or one item to fix. Look again in a year or two.
• Replace Soon: the roof is near the end across whole slopes. Most path two roofs land here by now, and so do most overlays.

The page on the Stow roof inspection and its three ratings lists everything that gets checked.

How do you plan the date and the money?

A roof that rates Replace Soon rarely has to be done that month. It has to be done before it leaks. That gives you room to plan. The written quote is one flat price and it is good for a year, so an inspection this winter fixes the number for a spring 2027 install.
