The Most Common Roof Defects We Find
The roof defects we most commonly find are cedar-shake end-of-life, ice dams and attic bypass, missing kickout and roof-to-wall flashing, granule loss, exposed fasteners, improper valley flashing, and inadequate ventilation.

Steep, complex, and cedar-shake roofs combined with Minnesota's freeze-thaw and hail history produce these recurring roof findings.
The Most Common Roof Defects We Find.
Steep, complex, and cedar-shake roofs combined with Minnesota's freeze-thaw and hail history produce these recurring roof findings.
Cedar Shake Roof End-of-Life
An end-of-life shake roof is a major replacement and a Class 4 / insurance conversation that directly affects negotiation.
Ice Dams & Attic Bypass
Ice dams drive water under shingles and shake into walls — a recurring Glen Lake and Greenbriar problem that damages finishes.
Missing Kickout Flashing
A single missing kickout flashing can rot a wall cavity for years before any visible stain appears.
Roof-to-Wall Flashing Failure
Roof-to-wall failures drive water directly into wall cavities and are a leading cause of concealed rot on lap-siding and EIFS homes.
Asphalt Granule Loss
Heavy granule loss exposes the asphalt to UV and accelerates failure, signaling a roof at or near end of life.
Exposed / Backed-Out Fasteners
Exposed fasteners are a frequent, easily-missed leak source that lets water into the deck and structure.
Improper Valley Flashing
Valleys carry the most water on a roof, so a flashing defect there causes outsized concealed damage.
Inadequate Roof Ventilation
Poor ventilation drives ice dams, attic condensation, and premature roof aging in our climate.
