Benzinger Roofing | Roofing Services in Granite Falls, MN 56241

In our Granite Falls climate, temperature swings cause roofing materials to expand and contract. This movement can push nails up (creating pops) and stress the critical seams in roof valleys. Combined with heavy snow and rain, these weak spots are prime areas for leaks. Our repair process addresses both the symptom and the underlying cause to prevent recurrence.

Repairing a valley leak starts with a thorough inspection to find the exact breach. We carefully remove damaged shingles or valley metal, repair or replace the underlying decking if needed, and install a new, watertight valley system. We use high-quality ice and water shield—a crucial step for our Minnesota winters—and ensure proper sealing and flashing integration for a long-lasting fix.

Absolutely. For isolated nail pops, we can carefully remove the affected shingle, drive a new, longer roofing nail into the roof deck (not just the sheathing), and seal it properly before reinstalling the shingle. We always check the surrounding area for other potential pops. This targeted repair is a cost-effective solution to prevent moisture intrusion and extend your roof's life.
