4 Signs an Older Phoenix Home Needs Gutter Work

Older Valley homes, anything built before roughly 2000, share a set of gutter problems, because they largely shipped with the same system and that system has now aged past its design life.

Look at the joints

Most of these homes got sectional aluminum gutters joined every ten feet with sealant. Arizona UV exposure degrades that sealant far faster than the manufacturer’s rating assumes, and thermal cycling, a hundred-degree swing between a July afternoon and a January night, works the joints loose. Walk the perimeter and look at every seam. Staining below a joint means it’s already leaking.

Look behind the gutter, not at it

Water that gets behind a gutter runs down the fascia where you can’t see it. Check for peeling or bubbling paint on the fascia board, dark staining, or softness if you can reach it. On homes with wood fascia this is where the expensive damage lives.

Check the pitch after a storm

Standing water in a gutter an hour after the rain stops means the slope is gone. On older homes the usual cause is spike-and-ferrule hangers, the original hardware on most of these houses, which loosen over decades of expansion and contraction. Modern hidden hangers screw into the fascia and hold far better.

Check the size against the roof

A lot of older Valley tract homes were fitted with 5-inch K-style regardless of roof area. If your gutters overflow during monsoon even when they’re clean, that’s a capacity problem, not a maintenance problem, and it’s common on two-story homes and homes with large single-slope roof planes. The fix is 6-inch gutter and oversized downspouts.

One more thing specific to older homes: if the roof has been replaced at some point, check where the gutter meets the drip edge. Roofers and gutter installers are usually different crews, and a roof replacement that didn’t account for the existing gutter can leave a gap that sends water behind the run every time it rains.
