Several warning signs indicate siding damage requiring prompt attention. Visible cracks, holes, or loose panels are obvious indicators, but other signs are more subtle. Inside your home, look for water stains on walls or ceilings, unexplained drafts, or sudden increases in energy bills that might indicate compromised exterior protection.
Outside, check for warped or buckled panels, gaps between siding and trim, or areas where caulking has failed. After storms, inspect for impact damage from debris, even if it appears minor. Small dents or cracks can allow water infiltration that leads to much more expensive problems over time.
Mold, mildew, or discoloration on siding surfaces often indicates moisture problems that need immediate investigation. These issues rarely improve on their own and typically worsen rapidly, especially in Long Island’s humid coastal environment. Early intervention prevents minor problems from becoming major structural issues.
