Crown Battery


In 1962, William J Koenig, a German immigrant pursuing the American dream, opened the doors to a small battery repair shop in Fremont, OH.
More than 85 years of experience with lead-acid batteries, chargers, and related accessory products have made Crown Battery a leader in the global battery industry.

-
- Multiple sections of the roof were extremely corroded and rotted through.
-
- Internal gutters had rotted through.
-
- Condensation was continuously reactivating chemical vapors, causing fast-forming rust.
Located in northern Ohio, the Crown Battery facility sees high winds and sufficient precipitation throughout most of the year. That means any crack, exposed seam, or puncture is collecting water all year long.
Weather aside, what was taking place under the roof contributed to the accelerated degradation rate.
The production of lead-acid batteries is corrosive by nature and includes a combination of dangerous chemicals and heat treatment.
Industrial roofs usually have very specific points in their building where the roof system is degrading faster than the rest of it.

Industrial roofs usually have very specific points in their building where the roof system is degrading faster than the rest of it.
These vulnerable points are almost always underneath areas of concentrated heat, chemical off-gassing, or structural damage.
When one area of the roof gets damaged, managers have to move whatever is under it to a new facility area. And the same thing will happen again and again.
We’re proud to have been working with Crown Batter for more than 15 years – In helping them to restore their roof, section-by-section.
