The inspection begins with the area related to the leak or visible damage.
Shingles, flashing, penetrations and roof edges are checked as appropriate to the roof.
When damage remains localized, repair may preserve the larger system.
Metal Roofing
Metal-roof projects require attention to panel type, attachment, flashing and penetrations.
Standing-seam and exposed-fastener systems behave differently and should be inspected accordingly.
Commercial Properties
Commercial service may include metal and low-slope roofing.
For larger buildings, provide approximate building size, roof type if known and the location of any interior leaks when requesting service.
This helps determine whether the project fits the extended service schedule.
Replacement
Replacement becomes appropriate when overall roof condition makes repair increasingly unreliable.
The scope should account for the roofing material and the underlying assembly rather than simply replacing the visible surface.
