Ducts and Vents

Remove mesh cover on dryer vent on the roof. The dryer duct got clogged by the mesh cover so the moisture cannot escape. We had 1.5 years dryer repaired because of the busted control panel. I need someone to go on top of the roof to cut off the mesh cover on the vent exit. It is 3 stories townhome, you may need 40 feet ladder to get on the roof. The roof is almost flat and easy to walk on once you get on the roof. I would need to have before and after pictures taken so I can make sure the clogging has been removed. It would be great if you can also do the dryer duct clean after the mesh cover is removed. Thank you!!
