Santiago Roofing Solutions | Roofing Services in Sioux Falls, SD 57104

In Sioux Falls, our heavy snowfall and frequent freeze-thaw cycles are the main culprits. Snow and ice accumulate in roof valleys, creating pressure and potential for ice dams that force water under shingles. This water can then saturate and degrade the underlayment, which is your roof's secondary water barrier. Once the underlayment is compromised, leaks into your attic and home are much more likely. We see this damage pattern frequently and focus on reinforcing these critical areas.

Our process starts with a thorough inspection to find the exact point of failure. We then carefully remove the damaged shingles and any compromised underlayment in the valley. We install a new, high-grade ice and water shield—a self-sealing underlayment specifically designed for vulnerable areas like valleys—before re-shingling with precision. The goal is not just to patch the leak but to rebuild that section to be more resilient against future ice dams and water intrusion, a common need for Sioux Falls roofs.

Signs often include interior water stains on ceilings or walls, especially after a snowmelt, or a musty odor in your attic. While not always an immediate structural emergency, underlayment damage is serious because it means your primary roof defense is gone. We recommend scheduling an inspection promptly, especially before the next major storm or winter season. In Sioux Falls, delaying repair can lead to more extensive—and expensive—issues like mold growth or rotten roof decking.
