Roof leaks rarely happen randomly. They typically result from one of several common roofing failures.

Most Common Causes

• Failed flashing

• Cracked pipe boots

• Worn underlayment

• Missing shingles

• Improper installation

• Clogged valleys

Why Leaks Often Appear Far From the Source

Water travels along decking and rafters before dripping down. The visible stain may not be directly under the leak source.

Why Immediate Repair Matters

Even small leaks can cause:

• Mold growth

• Insulation damage

• Structural rot

• Ceiling collapse
