“Ya there are some crumbs and debris in the crack too. Can't get it out. It has never been sealed for many years but I thought it might look nicer and clean easier and not get more debris in there”source ↗
“It seems pretty restrictive, and my gutters are overflowing during heavy rain.”source ↗
“My main concern now is protecting my buried PVC drainage that runs to the street without restricting the downspout and causing the gutter to overflow.”source ↗
“Should i take a shovel and clear it more so the whole thing is available to catch water? How to prevent weeds from encroaching on it? How to prevent clogs, etc.”source ↗
“No one wants to be the first to drop ten grand on a motorised roof drain spinner just to have it seize up six months in and void their insurance claim when the ceiling caves in anyway.”source ↗
“So, let me get this straight. It's 2026 and there are still flat roof drains that get clogged with debris? And it causes thousands of dollars worth of damage when the water can't go down the gutter drain?”source ↗
