Scorproofin | Roofing Services in South Saint Paul, MN 55075

In our area, heavy snow and the freeze-thaw cycle put immense stress on these critical junctions. Valleys channel large volumes of water and debris, while flashing can separate from roof planes due to expansion and contraction from temperature swings. This makes them the first points of failure, leading to interior water damage.

A proper repair starts with removing the old, compromised valley material. We then install a new, high-capacity metal valley liner, sealed with ice and water shield for an extra layer of protection. The key is ensuring a wide, water-tight channel that can handle South Saint Paul's heavy runoff without allowing water to back up under the shingles.

We remove the old caulk or sealant and any damaged flashing sections. The area is cleaned and dried, then we install new, properly sized flashing that's integrated under the roofing material and securely fastened. We use professional-grade, flexible sealants designed to withstand our local temperature extremes, creating a durable, long-lasting seal.
