Identify costly metal roof problems early with six safety checks you can perform from the ground to avoid expensive emergency repairs.
Share:
Summary:
Walk around your property and examine your metal roof from multiple angles using binoculars for detailed inspection without climbing. Look for panel alignment irregularities, color variations that indicate coating failure, and any areas where panels appear lifted or shifted from their original position. Missing or loose panels create obvious gaps in your roof’s protective envelope, while subtle panel lifting may indicate fastener failure or thermal movement problems that will worsen over time. Rust stains appearing on panel surfaces or at seam locations signal corrosion that requires immediate attention before it compromises structural integrity. Denting from hail impact may not create immediate leaks but weakens the metal and creates stress concentration points where future failure is likely. Oil canning—visible waviness in panel surfaces—indicates installation problems or thermal stress that can lead to fastener loosening and eventual water infiltration. Document any concerns with photographs that show the problem area and surrounding context, as this information helps roofing professionals diagnose issues accurately and plan appropriate repairs. In Michigan’s climate, small problems identified during ground-level inspection can prevent major failures during winter ice loading or summer storm events.
Inspect your attic space monthly for water stains, dampness, or active dripping that indicates roof penetration failures. Check areas directly below roof penetrations like vents, chimneys, and satellite installations where flashing problems commonly develop. Use a flashlight to examine insulation for water staining or compressed areas that suggest repeated moisture exposure. Fresh water intrusion appears as dark stains or damp areas, while older leaks show as brown or yellow discoloration with possible mold growth around the edges.
Use binoculars to examine exposed fasteners for missing caps, raised heads, or corrosion staining that indicates seal failure. Standing seam systems should show uniform seam height and alignment, with no visible separation or panel edge lifting. Mechanical seaming problems create water entry points that appear as gaps or irregularities in the continuous seam line. Focus attention on seam intersections and panel terminations where complex details concentrate stress and increase failure probability.

Metal roof surface condition directly affects longevity and performance, making regular assessment valuable for predicting maintenance needs and planning repairs. Examine your roof’s finish for chalking, fading, or glossy areas that indicate coating deterioration and reduced weather protection. Scratches from tree contact or debris impact create corrosion initiation points that spread rapidly if left untreated. Accumulated debris in valleys or around penetrations traps moisture and creates corrosive conditions that accelerate metal deterioration. Algae or moss growth indicates prolonged moisture retention that can compromise panel coatings and create slip hazards during maintenance activities. Granular material accumulation from nearby deteriorating asphalt roofs can create abrasive conditions that scratch metal surfaces during wind events. Check for oil staining from HVAC equipment or other rooftop installations that can degrade protective coatings and create corrosion problems. Surface temperature variations visible as frost patterns or snow melt differences may indicate insulation problems or air leakage that affects energy efficiency. Hamdan Quality Roofing’s assessment process includes thermal imaging that reveals hidden moisture problems and insulation deficiencies not visible during standard inspections.
Examine flashing around chimneys, vent penetrations, and roof-to-wall transitions for gaps, lifted edges, or sealant deterioration that creates water entry points. Properly installed flashing should lie flat against surfaces with no visible gaps or raised edges that allow water infiltration. Look for rust staining below flashing areas that indicates ongoing water problems requiring immediate attention. Missing or damaged step flashing at roof-to-wall intersections creates vulnerability to wind-driven rain penetration.
Roofs approaching 25-30 years of age require more frequent assessment as multiple system components begin showing wear simultaneously. Look for widespread coating deterioration, multiple panel replacement needs, or structural sagging that indicates your roof is approaching replacement time. Professional evaluation helps determine whether continued maintenance makes economic sense or if replacement provides better long-term value. Consider replacement timing to avoid emergency situations during severe weather seasons.
These ground-level checks provide valuable early warning of developing problems, but professional assessment remains necessary for accurate diagnosis and repair planning. What appears minor from the ground may indicate significant hidden damage requiring immediate attention, while obvious problems might have simple solutions that prevent expensive repairs. In Lenawee and Washtenaw Counties, where weather extremes test every roofing system, combining your regular observations with professional expertise provides the best protection for your investment.
