Philadelphia is notorious for its beautifully designed and planned streets and their attached row homes. The roofs were designed with a slight pitch so that water will gently flow in the direction of one corner (usually the rear corner) of the roof.
In the corner of the roof where all the water drains there is a point at which the top structure of the roof has a cutout with a sturdy metal box fastened in the collection point called an eave box, or a gutter. Water can flow into this box and down the downspout and either into an open space away from your foundation or into an exterior drain.
Flat roofing has so many benefits. They are easy to maintain, easy for roofing contractors to access and safely walk on, easy to install and easy to replace!
