In our climate, heavy snow accumulation and repeated freeze-thaw cycles put immense stress on roof valleys and metal flashing. Valleys channel large volumes of water and melting snow, and if not properly sealed or reinforced, that constant flow can wear through materials. Flashing around chimneys, vents, and skylights can corrode or pull away from temperature changes and ice expansion, creating gaps. We focus on reinforcing these areas with ice and water shield and corrosion-resistant flashing to prevent these specific local failures.

Repairing a valley leak starts with a thorough inspection to find the exact failure point, often under layers of ice and water damage. We carefully remove compromised shingles and underlayment in the valley. The key is installing a new, wide valley liner—often a heavy-gauge metal or specialized waterproof membrane—that extends well under the surrounding shingles. We then re-shingle with proper overlap to ensure water is shed quickly off the roof, a critical step for handling our heavy spring runoff and summer downpours.

Look for signs of rust, corrosion, or gaps where the flashing meets the roof or a vertical surface like a chimney. Inside your attic, check for daylight coming through around pipes or vents, or look for water stains or moisture on the sheathing near these penetrations. In Dickinson, flashing failures often become apparent during or after a heavy melt when water finds these new paths. If you see these signs, it's best to have a professional assessment quickly, as a small flashing issue can lead to significant interior damage.
