Short Answer
Evaluate roof, flashing, gutters, downspouts, siding, windows, doors, soffit, fascia, attic ventilation, and visible moisture issues.
Detailed Explanation
Fall is the time to prepare the home's exterior for the harsh winter ahead. Key preparations include: inspecting the roof for damaged or missing shingles that could fail under snow and ice; checking flashing for gaps or deterioration that could allow water intrusion; cleaning and inspecting gutters and downspouts to ensure proper drainage before freezing; checking siding for damage or gaps; inspecting windows and doors for air leaks or water intrusion; evaluating soffit and fascia for damage; checking attic ventilation for adequacy; and addressing any visible moisture issues. The goal is to identify and correct problems before winter, when cold weather, snow, and ice make exterior work difficult and expensive. A professional fall inspection can identify issues that homeowners might miss.
Why It Matters
Preparing the exterior in fall prevents winter emergencies. Small problems addressed in fall are much less expensive than emergency repairs in winter.
