This is a common rooftop dryer vent exhaust. The dryer for this unit was located in the hallway of the second floor behind a set of by-fold doors. This vent has only a small area to allow hot air & excess lint to escape, so it quickly builds up. This turns the simple task of drying clothes into what could be something more serious.
Another sign of trouble is the lint that has been building up begins to build up on the roof shingles. We’re Top Notch Chimney Sweeps & We’re The Dryer Vent Pro’s! We’ll get the lint out. Call us today at 515-249-6337.
