Constitution Town Era Houses in Louisville, Ohio, and Their Roofs
In the 1950s Louisville, Ohio, earned the name that still sits under the city's logo: the Constitution Town. The same decade built the first of its ranch streets. Those houses are about seventy now, and their roofs have a history worth knowing.

How did Louisville become the Constitution Town?
Through one persistent resident. In 1952 Olga T. Weber of Louisville petitioned for a day to honor the United States Constitution. Ohio answered first, proclaiming September 17 as Constitution Day statewide. Weber then took the idea to Washington and asked for a full week. Congress agreed, and President Dwight D. Eisenhower signed Constitution Week into law. On April 15, 1957, Louisville's council made it official at home and declared the community the Constitution Town. Three years later, in 1960, residents voted to turn the village into a city. Louisville still holds a Constitution Week celebration every year around September 17.
What was being built in Louisville in those years?
Houses, and quickly. The census counted 3,801 people in Louisville in 1950 and 5,116 in 1960, a jump of about 35 percent in ten years. Current census estimates find 483 homes in the city that date from the 1950s and another 149 from the 1940s. They are the small ranches, story-and-a-half houses and early split-levels on the streets just outside the old downtown grid.
How were roofs built on a 1950s house?
Differently from today in almost every layer. If you own a house from this period, this is what was typical when it was new.
- Decking. The 1950s were the changeover from sawn boards to plywood. A house from early in the decade often has one-by boards nailed across the rafters. A later one may have thin plywood.
- Shingles. Flat 3-tab shingles on an organic felt mat. Fiberglass mats and laminated architectural shingles came later.
- Underlayment. Asphalt felt paper. No self-adhering membrane at the eaves, because it did not exist yet.
- Edges. Often no metal drip edge. The shingles simply overhung the wood.
- Ventilation. A louver in each gable end. Ridge vents were not in use.
- Insulation. A few inches at most, far below what is put in now.
None of that was poor work. It was the standard of the day.
How many roofs has a Constitution Town era house had?
Do the arithmetic for a house finished in 1955. Its first roof would have lasted into the 1970s. The second, likely nailed over the first, into the 1990s. A third, hopefully after a tear-off, would have gone on somewhere around 2000. If that is the roof on the house today, it is at least twenty-five years old. If there has been a fourth, it may be only ten.
The point is that you cannot tell from the street. Two identical ranches side by side can have roofs twenty years apart in age, and one may be carrying two layers while the other has one. That is the case for having it looked at, and the free roof inspection in Louisville is built for exactly this question.
What tends to turn up on a roof of this age?
- Two layers of shingles, visible as a thick edge at the gable.
- Board decking with a few split or soft boards near the eaves, where decades of ice have worked on them.
- Water stains low on the underside of the deck, the mark of old ice dams.
- A chimney whose flashing has been coated with roof cement more than once.
- A bath fan added in a later remodel and left to blow into the attic.
- A breezeway, porch or patio roof at a very low pitch, tied into the main roof.
What does a modern replacement fix that earlier reroofs skipped?
A layover in 1975 or 1995 put new shingles on and changed nothing else. A full replacement today is the first time in decades that the deck is bare, and it is the chance to bring the whole assembly up to date.
- Every board is seen. Bad ones are replaced before anything covers them again.
- The eaves get a membrane. Self-adhering ice and water shield goes on from the edge up past the wall line, which is the answer to those old stains.
- The edges get metal. Drip edge at the eaves and rakes protects the ends of the boards and the fascia.
- The attic gets air. A ridge vent, with the soffits opened to feed it, replaces the gable louvers as the main exhaust.
- The shingles are a different product. Laminated architectural shingles on a fiberglass mat, with a wind rating the originals never had. The architectural shingles page has the comparison.

Where do you start?
With the age of the roof and the number of layers. If you know both and the roof is under fifteen years old, you can likely relax. If you know neither, book a roof inspection with a photo report. It costs nothing, and you end up with pictures of the deck, the attic and every slope, plus a rating of Good, Watch or Replace Soon.
