Metal roofs in McLennan County expand and contract daily under hot humid summers, loosening screws and opening seams especially on older homes in East Waco and Sanger Heights. Spring storms bring sudden downpours that find these gaps fast, sending water along purlins into attics. We check both the visible fasteners and the hidden lap edges because simply adding sealant on top rarely lasts through the next temperature swing.
Waco’s mild winters still allow enough thermal movement to fatigue flashing around chimneys and skylights on metal roofs near Baylor University and Cameron Park. Homeowners often miss corrosion starting at the cut edges of panels after years of condensation. Proper repair means replacing the affected fastener with a larger EPDM washer screw and cleaning the surface so new sealant bonds, rather than layering product over rust.
Properties in West Waco and Dean Highland sit on slightly higher ground but still see wind-driven rain during storms that pushes water under ridge caps. We always verify the original panel gauge and coating type before touching anything, because mismatched screws create new leak points within a season. Work stays limited to the damaged section unless the owner requests a full inspection of the entire slope.
Technician insight
In Waco, the thing that catches most people out with Metal Roof Leak Repair is assuming the leak is only at the obvious hole. Humidity in McLennan County makes metal move enough that water often travels several feet along a purlin before dripping, so we always trace from the attic on homes in East Waco and Sanger Heights.
East Waco Metal Roof After Spring Storm
Water appeared in the attic near a bathroom vent on a 1990s metal roof. We found the ridge cap had lifted from wind-driven rain and several fasteners had backed out along the seam. New screws and fresh sealant at the cap stopped the leak without replacing panels.
