Chimney Flashing Repair in Sanford, FL

Flashing at a masonry chimney is two layers doing two jobs. Step flashing is woven into the roofing course by course and turned up the masonry; counter-flashing is let into a mortar joint, folded down over the step pieces and sealed at that reglet, so the seal is mechanical rather than dependent on caulk holding to brick. Two details get skipped. Code calls for a cricket on the up-slope side of any chimney wider than about thirty inches, a small framed saddle that splits water around the stack instead of letting it pile up. And where the leak has been chased before, the tell is roof cement over the seam: it holds a season, then hardens and cracks, concealing the joint while it fails. Strip it and rebuild the metal.

The roof covering, chimney shape, access, and condition beneath the flashing affect the repair. Replacing visible metal alone is not the same as repairing an underlying roof or wall connection. Compare whether removal and reinstatement of adjacent roof materials are included, and ask how concealed damage would be handled if found.

• What roof covering is present, if known?
• Where is the indoor stain, and which weather brings the leak?
• Did the problem start or change after roof work?
