Your roof is your home's first line of defense against Iowa's punishing weather — spring hail, summer derechos, and brutal freeze-thaw winters. But because most of it is out of sight, it's easy to miss the warning signs until a small problem becomes a leak. Here are the 10 signs Eastern Iowa homeowners should watch for.
Shingles that curl at the edges or buckle in the middle have lost their weather seal. In Iowa's freeze-thaw climate, that's an open invitation for water intrusion.
Find sand-like granules collecting in your gutters or at the bottom of downspouts? Those granules protect your shingles from UV and impact. Heavy granule loss means your roof is aging out.
High winds and hail routinely tear or crack shingles across Eastern Iowa. Even a few missing shingles expose the underlayment and decking beneath.
If you can see daylight through the roof boards — or spot water stains and damp insulation in the attic — water is already getting in.
A sagging roof deck signals trapped moisture and possible structural damage. This one needs prompt professional attention.
Brown rings on your ceiling are a classic leak symptom. The source is often higher up the roof than the stain itself.
Most asphalt shingle roofs last 20–25 years — less when battered by repeated Iowa storms. If yours is near that age, have it inspected before it fails.
The metal flashing around chimneys, vents, and skylights is a common leak point once it cracks or pulls away.
Moss traps moisture against shingles, and soft, rotting decking compromises the whole system.
A failing roof and poor attic ventilation let conditioned air escape, quietly driving up your heating and cooling costs.
