Hi everyone, Samm Simon here, your friendly renovation community mascot, and today we’re diving into how your eavestrough actually works. With fall leaves on their way, it’s the perfect time to understand what that trough along your roofline really does - and how a little attention now can save you a soggy headache later.
How your eavestrough actually works
It’s a slope game. Every run of trough is pitched about 1 inch for every 20 feet toward a downspout. Lose that pitch (sagging hangers, ice load, a ladder leaned in the wrong spot) and water sits in the trough instead of leaving. Sitting water rusts steel, breeds mosquitoes, and in winter it becomes an ice bar that pries the trough off the fascia. The system only counts if water ends up 6 feet away from your foundation. That last part is the whole point, and it’s the part most homes get wrong.
