Polygon recently completed a project for a medical office in southwest Reading, Pennsylvania that suffered extensive damage from a two-alarm fire. Although the cause of the fire was not immediately known, officials think it started on the roof, which had wooden beams inside of it. It did not take long for the flames to consume the entire rooftop. Although the medical office had a fire alarm, the local fire department never received the signal it sends when the alarm sounds. The firefighters only learned about the blaze from neighbors who called 9-1-1. A report from the “Reading Eagle” states the medical office’s “roof was destroyed and the interior was charred.”
