          Answer This Question

          A:  Yes but the screen has to be removed or lint will build up and clog it. I've used this for over 20 years but it must be cleaned annually.

                Very cheap construction
                Very low quality. thin metal, scratched, bent. Would never trust my roof to this level of product quality.

                  Through the roof.......
                  This one has the tube that goes through the roof so that the hose is easy to attach.
