It’s really smart to inspect your rain gutters from time to time.
I know a lot of people who don’t even think that they’re important for any reason, let alone for roof leaks.
The reality of rain gutters is far graver than what these people could ever imagine. If you don’t keep them free of leaves and other yard debris, the water flows backward onto the roof as it rains. It collects at the edge of the roof and can soak into the wood under the shingles. Think of it like this—without the gutters, the water simply flows off the edge of the roof and onto the ground below. If there was a large obstruction along the entire edge of the roof, water would simply pool along the edges and soak into the plywood under the shingles. With enough time, it could cause a massive roof leak that would lead to mold in your attic with thousands of dollars worth of water damage to repair. Whenever I check my gutters once a month, I also look at the exit point for my central HVAC system’s condensate line. It’s a small PVC pipe that sticks out the side of one’s home, often near the HVAC condenser unit. If you don’t see water exiting this pipe while the air conditioner is running, you need to shut your system down immediately and clear out the line with a vacuum cleaner. This procedure is covered by my HVAC maintenance contract and my technician does it every time he’s at my house. A clogged condensate line can cause a huge water leak inside the house.
