Yes, it can. Adding a deck or building an addition can sometimes alter airflow around your roof's soffits. At Sons Construction, we carefully plan all projects to ensure proper roof ventilation is maintained or improved. For decks, we design to avoid blocking critical intake vents, and for additions, we integrate the new roof section seamlessly with your existing ventilation system to prevent ice damming and interior frost—common problems we see in Pequot Lakes.

Flashing—the metal strips sealing roof joints—often fails due to age, weather, or improper installation. In our area, freeze-thaw cycles are a major culprit. Interestingly, an old, decaying deck attached to the house can accelerate this damage by trapping moisture against the siding and roof edge. When we perform a deck replacement or repair, we inspect and, if needed, repair or replace the step flashing where the deck meets the house. This protects your home's envelope and prevents the water intrusion that leads to flashing separation.

Excellent question. When constructing an addition, integrating the new roof with the old system is critical. We calculate the required ventilation for the entire expanded roof area, ensuring balanced intake and exhaust. We use high-quality, ice-and-water shield at the eaves and properly install continuous ridge and soffit vents as needed. This proactive approach, tailored to Pequot Lakes' climate, prevents the warm, moist air from your home from condensing and freezing in the attic—solving frost issues before they start and protecting your investment.
