The Four Pillars of a Professional Roof Inspection
\n\n
Every thorough roof inspection examines four critical areas: the structural integrity of your roof deck, the condition of all roofing materials, the interior attic space for ventilation and moisture issues, and the quality of previous workmanship. Missing any of these pillars means potential problems go undetected. High Quality Roof Replacements for Creve Coeur Properties.
\n\n
Structural Inspection: The Foundation of Roof Health
\n\n
The structural inspection begins with examining your roof deck from the attic. Our technicians look for sagging areas between rafters, which often indicate water damage or inadequate support. In St. Louis homes, we frequently find issues in areas where the roof meets dormers or where previous owners added skylights without proper reinforcement..

\n\n
Outside, we check fascia boards for rot, which commonly occurs when gutters overflow during heavy spring rains. We also inspect chimney masonry for cracks that allow water infiltration during freeze-thaw cycles. The St. Louis area’s expansive clay soil causes foundation movement that can misalign roof structures over time..

\n\n
\n\n
Material Inspection: Surface Protection Assessment
\n\n
The material inspection examines every layer of your roof’s protective system. For asphalt shingles, we check for granule loss, curling edges, and missing pieces. St. Louis’s high humidity creates ideal conditions for algae growth, particularly on north-facing slopes where moisture lingers..

\n\n
Flashing inspection is critical in our region. We examine metal flashing around chimneys, vents, and valleys for rust or separation. Missouri’s Building Code Section 1507.2.8 requires ice and water shield installation in valleys and along eaves in St. Louis County to prevent ice dam damage.
\n\n
Our technicians also check pipe boots, which deteriorate faster than other components due to constant exposure to exhaust heat and UV radiation. A failed pipe boot can leak for months before showing interior water stains, making regular inspection essential..

\n\n
Interior Inspection: The Hidden Damage Detector
\n\n
The interior inspection often reveals problems before they become visible from outside. We enter your attic with moisture meters to detect damp insulation, which indicates active leaks even when no water drips through your ceiling.
\n\n
Ventilation assessment is particularly important in St. Louis’s humid climate. Poor attic ventilation causes moisture buildup that leads to mold growth and premature shingle deterioration. We measure temperature differentials between attic spaces and living areas to identify ventilation problems.
\n\n
We also check for proper insulation levels and look for signs of animal intrusion, which is common in older St. Louis neighborhoods where squirrels and raccoons seek winter shelter.
\n\n
Workmanship Inspection: Previous Installation Quality
\n\n
The workmanship inspection evaluates the quality of your roof’s original installation or any previous repairs. We look for common issues like overdriven nails, which create entry points for water, and improper shingle alignment that accelerates wear.
\n\n
In St. Louis, we frequently find problems in homes where contractors skipped required underlayment installation to cut costs. This shortcut becomes obvious when we find exposed decking or inadequate drip edge protection.
\n\n
We also check for proper fastener spacing and pattern, which affects wind resistance. Given St. Louis’s location in Tornado Alley, proper fastening is not optional but essential for safety.
\n\n
Specific Issues for St. Louis Roofs
\n\n
St. Louis’s climate creates unique roofing challenges that require specialized inspection knowledge. Our technicians understand these local factors and know exactly what to look for.
\n\n
Hail Damage Assessment
\n\n
St. Louis experiences frequent hail storms, particularly in spring and early summer. Hail damage often appears as dark spots where granules have been knocked off shingles, exposing the asphalt layer underneath. These spots feel softer to the touch and may show cracking under magnification. Fixing Wind and Storm Damage Before It Ruins Your St. Louis Home.
\n\n
We use the “quarter test” to determine if hail damage warrants insurance claims. Dents larger than a quarter typically indicate structural damage that will lead to leaks within 12-24 months if left unrepaired.
\n\n
Ice Dam Prevention
\n\n
Missouri winters create ice dam conditions when snow melts on warm roof surfaces and refreezes at the eaves. We inspect for proper ice and water shield installation, which St. Louis County requires to extend at least 24 inches past the exterior wall line.
\n\n
We also check attic insulation levels, as poor insulation allows heat to escape and melt snow unevenly. This creates the temperature differential that causes ice dams to form.
\n\n
Humidity and Ventilation Concerns
\n\n
St. Louis’s high humidity levels create unique attic ventilation challenges. We measure relative humidity in attic spaces and check for proper ridge vent installation. Without adequate ventilation, moisture condenses on the underside of roof decks, leading to rot and mold growth.
\n\n
We also inspect bathroom and kitchen exhaust vents to ensure they terminate outside rather than into the attic, a common problem in older St. Louis homes that can cause significant moisture damage.
\n\n
The Inspection Report: What You Receive
\n\n
After completing the inspection, we provide a comprehensive report that includes color photos of all findings, moisture readings, and specific recommendations. The report categorizes issues by urgency: immediate repairs needed, recommended maintenance, and items to monitor.
\n\n
We also include estimated repair costs and warranty information for any recommended work. Our reports are detailed enough to satisfy insurance adjusters when storm damage is involved.

Frequently Asked Questions

We recommend professional inspections every two years for roofs under 15 years old and annually for older roofs. After major storms, immediate inspections are crucial to catch damage before it worsens.

Can I inspect my own roof?
\n
While you can spot obvious problems like missing shingles, professional inspections use specialized tools and expertise to find hidden issues. Walking on your roof also risks damage and personal injury.

Spring and fall are ideal for inspections in St. Louis. Spring inspections catch winter damage, while fall inspections prepare your roof for harsh winter conditions.
