Yep. Only killed plant life on two different occasions and one was a reaction with fertilizer. I don’t think it’s a good move to leave that much SH on anything especially with nails, screws, vents, etc, etc. so I don’t.
Neither. I just don’t know what I’m supposed to do with bags of bleach? I soak the areas by the downspouts before, while the roof is coated, and after I rinse. Water is pretty much always flowing.
Just bought a 1000ft roll of 6 mil poly tubing it worked perfectly. super strong. in the long run it’s less expensive than trash bags and you can carry it to where you’re dumping with no worries
