Why do my gutters sag even though they are not that old?
Sagging happens when gutters are not supported with enough fasteners, when the slope is wrong (no slope toward the downspout), or when water-laden debris is sitting in the gutter adding weight. On the Middle Peninsula, clogging from falling limbs and tree debris accelerates sagging.
Gutters should be fastened every 24 inches and sloped 1/16 inch per foot toward the downspout. If yours are fastened every 30 or 40 inches, or have no slope, they sag.
Ask the roofer about re-hanging and re-sloping the gutters. It is less expensive than replacing them if the material is still sound.
Do gutter screens work?
Partially. Screens reduce the amount of debris in the gutter, but they do not eliminate the need for cleaning. Leaves and needles can accumulate on top of the screen, blocking water. Heavy rains can also push debris through the screen. Regular cleaning is still needed.
On a coastal home with many trees, a screen is worth having but is not a substitute for maintenance.
Some screens are more effective than others. Discuss options with the roofer and look at examples before choosing.
Where should my downspout drain?
The downspout should direct water at least 4-6 feet away from the foundation so that water does not pool against the foundation wall. An underground drain or a sump pit may be needed if grading is poor and water comes back toward the house.
If a downspout empties 1-2 feet from the foundation, water will pool there in rain and seep into the basement or crawlspace. Extend the downspout or install an underground drain.
Watch where water goes after a hard rain and adjust the downspout if needed.
How often should gutters be cleaned?
Twice a year at minimum: in late fall after leaves drop, and in spring after tree pollen and any winter debris accumulates. In a coastal area with many trees, quarterly cleaning might be worthwhile.
A clogged gutter is worse than no gutter because it forces water under the roof or down the fascia where damage happens fast.
If your gutters clog frequently, consider gutter screens or a more regular cleaning schedule.
