Shingle Installation Deficiencies after review of Tri-states work completed-Review by third part expert
A substantial number of synthetic cedar shingles were found to be loose, improperly fastened, or unstable under foot traffic.
Improper nailing patterns and/or fastening techniques appear to have been used.
Shingles lack uniform alignment, contributing to visual inconsistency and compromised performance.
The instability increases the risk of wind uplift and premature system failure.
B. Roof Surface Deformation (Waviness & Warping)
The roof surface presents visible waviness and uneven planes, indicating:
Poor decking preparation, or
Improper installation techniques.
Warping suggests improper fastening or underlying structural inconsistencies, which can accelerate wear and reduce the lifespan of the roofing system.
C. Flashing Failures
Flashing at roof-to-wall intersections was observed to be incorrectly installed and inadequately sealed.
These areas are highly vulnerable and currently represent primary points of water entry.
Industry-standard step flashing and counter-flashing practices do not appear to have been followed.
D. Siding and Exterior Damage
During installation, the contractor caused notable damage to siding and J-channels.
Improper handling and lack of care during roof tie-ins resulted in cosmetic and potentially functional damage to adjacent exterior systems.
E. Active Leaks and Attic Conditions
The attic inspection revealed multiple active leaks, indicating systemic failure rather than isolated issues.
Evidence of water intrusion includes:
Moisture penetration
Potential early-stage wood damage
Risk of mold development if left unaddressed
This is particularly concerning given the roof's recent installation.
F. Lack of Proper Ventilation (Critical Issue)
The roofing system does not include a ridge vent, which is a critical component of modern roofing systems.
Proper ventilation is essential for:
Regulating attic temperature
Preventing moisture buildup
Extending roof lifespan
The absence of a ridge vent contributes directly to heat and moisture retention, exacerbating material degradation and increasing the likelihood of leaks and warping.
3. Overall Assessment
The roofing system, though recently installed at a premium cost, is currently failing across multiple critical performance areas due to poor workmanship and improper installation practices.
This is not a matter of minor repair -- the issues observed are systemic and widespread, indicating that the roof was not installed in accordance with industry standards or manufacturer specifications read more
