How to repair gaps on roofs joints
For gaps on or near flashing Thin aluminum sheets, called flashing, typically get installed under shingles to build a form-fitting barrier around anything that juts through a roof (a chimney, for example). Look for gaps in caulk, sealant or cracks on or around your roof’s flashing. If you find a gap under ¼”, it may be a simple fix once you brush away debris and old sealant remnants.
