Roof leaks don’t always start with missing shingles or major storm damage. In fact, one of the
most common and overlooked causes of roof leaks is flashing failure. At
Affordable Roofing, we regularly find that water intrusion starts around chimneys, vents, skylights, and wall transitions, all areas protected by flashing.
If flashing is damaged, improperly installed, or simply worn out, water will find its way in.
What Is Roof Flashing?
Roof flashing is a thin material, usually metal or membrane, installed at roof joints and penetrations to
direct water away from vulnerable areas. You’ll typically find flashing around:
- Chimneys
- Pipe vents
- Skylights
- Roof-to-wall transitions
- Valleys and edges
When flashing works correctly, water flows safely off the roof. When it fails, leaks are almost guaranteed.
Why Flashing Fails
Flashing problems happen for several reasons, especially in Illinois, where roofs are exposed to strong winds, heavy rain, snow, and freeze-thaw cycles.
Common causes include:
- Improper installation (a frequent issue on older roofs)
- Dried, cracked, or missing sealant
- Corrosion or metal fatigue
- Storm damage from wind or hail
- Roof repairs that disturb existing flashing
Even a small gap or lifted edge can allow water to seep underneath roofing materials and into your home.
Warning Signs of Flashing Failure
Flashing issues aren’t always obvious from the ground. Some warning signs homeowners should watch for include:
- Water stains on ceilings or walls
- Leaks near chimneys or vents
- Mold or moisture in attic spaces
- Loose or rusted metal around roof penetrations
If ignored, these small leaks can lead to rotted decking, insulation damage, and interior repairs.
Why Flashing Repairs Matter
Many homeowners assume a leak means they need a full roof replacement, but that’s not always the case. In many situations,
targeted flashing repairs or resealing can extend the life of your roof and prevent further damage.
At
Affordable Roofing, we inspect flashing as part of every professional roof evaluation and recommend repairs only when necessary.
