Why Does Water Drip Behind My Gutters?

If you’ve noticed water running down your siding or dripping behind your gutters during an Arizona rainstorm, it’s more than a small leak — it’s a sign that something’s missing or misaligned. That steady drip can stain stucco, damage fascia boards, and slowly erode your home’s exterior. At CR Gutters, Inc.™, we see this problem often across Arizona homes, especially those without drip edge flashing or with gutters misaligned from heat and monsoon wear.

Why Water Slips Behind Gutters

Gutters are designed to catch rain, but if the system is missing key components, water will take the path of least resistance. The most common causes include:

• Missing drip edge flashing: Without it, water flows behind the gutter instead of into it.
• Misaligned gutters: Even a slight shift can allow runoff to bypass the trough.
• Clogged or uneven sections: Arizona dust and debris can block water flow, pushing it behind the gutter.

During monsoon storms, these issues become more noticeable — resulting in streaks on stucco, dark roofline marks, or moisture buildup around trim.

How to Stop Water From Leaking Behind Gutters

Quick answer: Install drip edge flashing or a gutter apron to close the gap and guide water into the gutter.

A gutter apron is a curved metal piece placed under the shingles that overlaps the back of the gutter. It instantly redirects water into the gutter and prevents fascia rot. Our team at CR Gutters, Inc.™ checks alignment, evaluates roof edges, and installs secure flashing for long-term protection.

Signs You Need a Repair

Watch for these common warning signs:

• Dripping or running water behind gutters during rain.
• Stains on stucco or siding near the roof edge.
• Soft or peeling fascia boards.
• Water trails down your siding instead of the downspout.

Ignoring these signs allows moisture to spread — especially when paired with Arizona’s heat and monsoon humidity.

Typical Cost of Adding Drip Edge Flashing in Arizona

Most homes can add or replace drip edge flashing for $250–$600, depending on roof type and access. This upgrade is one of the most affordable ways to prevent leaks and protect siding, fascia, and foundations from long-term water damage.
