I couldn't find any related topics, so...
In my 3 month old new constructionhome I have a clogged dryer vent. The run of the dryer vent (galvanized pipe, 4" dia.) has a 90 going up to the ceiling, 40-45 to the roof and then a 40-45 to the roof vent. The roof vent (see pic) is where the clog is. Total length is about 15 ft. The clog occured at the roof vent. It built up ont the screen to prevent birds from entering (which is a HUGE problem in our sub division). It makes a perfect rectangular patch of lint. I don't want to remove the screen otherwise I"ll have birds in the vent. The screen is small, maybe 1/4" square mesh.
I don't want to have to climb up on the roof every two months to remove the build up. Any suggestions? Thanks in advance,
