Dw Construction | General Contractors & Roofing in Rapid City, SD 57703

In Rapid City, roof insulation moisture often stems from attic condensation due to our temperature extremes. We perform a thorough assessment of your attic ventilation and insulation levels. Our solutions may include installing proper ridge and soffit vents to promote airflow, adding vapor barriers, or upgrading insulation to prevent warm, moist air from reaching the cold roof deck. This protects your insulation's R-value and prevents mold and wood rot.

The rapid freeze-thaw cycles, snow accumulation, and exposure to elements in the Black Hills can accelerate flashing corrosion, especially around chimneys and valleys. We inspect all flashing for weakness. We then remove the corroded material and install new, high-grade metal flashing (like galvanized steel or aluminum), sealing it with durable, weatherproof compounds. Proper installation is key to preventing leaks and extending the life of your entire roof system.

Yes, absolutely. As a full-service general contractor, we address the problem from the roof down. If moisture from compromised insulation or flashing has caused interior ceiling stains, drywall damage, or mold, our team can manage the complete repair. This includes safe mold remediation, replacing damaged materials, and repainting—ensuring your home is fully restored inside and out after we fix the root cause on the roof.
