Introduction: Why Most Concord Homeowners Inspect Too Late
Most Concord homeowners inspect their roofs exactly once: when they notice water dripping from the ceiling during a winter storm. By that point, what could have been a $200 preventive repair has become a $5,000 emergency requiring interior damage restoration, mold remediation, and extensive roofing work—all while atmospheric rivers continue pounding the compromised roof.
The pattern repeats every winter at East Bay Roofers: frantic calls during major storms, homeowners discovering damage that's been developing for months (sometimes years), and emergency repairs that cost 10-20 times what preventive maintenance would have required.
Here's the fundamental truth about roof maintenance in Concord: Systematic inspection prevents catastrophic failure. Knowing what to check, when to check it, and which signs require immediate professional attention transforms roof maintenance from reactive crisis management to proactive protection.
Concord's unique climate—brutal summer heat, destructive fall Diablo winds, and concentrated winter rainfall—demands more frequent and specific inspection than standard "annual checkup" recommendations. Understanding Concord's inspection schedule means aligning inspections with climate-driven damage patterns.

Let's learn how to protect your home through systematic, intelligent roof inspection optimized for Concord's challenging climate.
Understanding Inspection Frequency: When to Check Your Concord Roof
Standard roofing industry guidance recommends "annual inspections." That's inadequate for Concord. Your climate creates four distinct damage seasons, each requiring specific inspection focus.
The Concord Inspection Calendar: Event-Driven Schedule
1. Post-Diablo Wind Inspection (After Major Wind Events, Fall)
Timing: Within 48 hours of any Diablo wind event with sustained winds over 35 mph or gusts over 50 mph
Why it matters: Diablo winds create immediate, visible damage—lifted shingles, displaced tiles, torn flashing, damaged gutters. This damage creates water intrusion points before winter rains arrive. The window between Diablo wind season (September-November) and winter rain season (December-March) is your opportunity to catch and repair wind damage.
What to inspect:
- Missing or displaced shingles/tiles, particularly on ridge lines and exposed corners
- Lifted shingle edges (wind gets under edge, breaks seal)
- Damaged or displaced flashing at chimneys, vents, and wall junctions
- Torn or separated valley flashing
- Debris accumulation in valleys and gutters (branches, leaves blown onto roof)
- Gutter sections pulled away from fascia
- Damaged or missing chimney caps
- Satellite dish or antenna displacement
Professional inspection recommended if: Visible damage from ground level, previous wind damage history, roof over 15 years old, or tile roof (tiles can shift without visible exterior signs).
2. Post-Summer Heat Inspection (Early October)
Timing: September-early October, after summer heat but before fall winds intensify
Why it matters: Concord's summer temperatures (regularly 95-105°F, roof surface temps 130-160°F) cause significant degradation that manifests as failures once winter rains arrive. Heat damage isn't immediately visible but creates vulnerabilities that water exploits.
What to inspect:
- Sealant condition around penetrations (look for cracking, brittleness, or complete failure)
- Rubber pipe boot condition (UV exposure makes boots brittle and cracked)
- Asphalt shingle granule loss (check gutters for excessive granule accumulation)
- Curling or cupping shingles (indicates aging and heat stress)
- Flashing sealant degradation (petroleum-based sealants fail in extreme heat)
- Skylight seal condition (glass-to-frame seals deteriorate from heat cycles)
- Attic ventilation effectiveness (excessive attic heat indicates inadequate ventilation)
Professional inspection recommended if: Roof over 10 years old, previous heat-related failures, dark-colored roofing (absorbs more heat), or inadequate attic ventilation.
3. Pre-Winter Preparation Inspection (Early November)
Timing: First week of November, before atmospheric river season begins
Why it matters: This is your last opportunity to identify and repair vulnerabilities before concentrated winter rainfall tests every weakness in your roofing system. This inspection combines findings from post-heat and post-wind inspections with comprehensive system assessment.
What to inspect: (Complete checklist detailed in next section)
- All items from post-heat and post-wind inspections
- Complete gutter and downspout system
- Valley cleanliness and integrity
- All flashing systems
- Drainage system functionality (actual water flow testing)
- Interior attic condition
- Emergency preparedness
Professional inspection recommended for: All roofs over 15 years old, any roof with previous leak history, tile roofs regardless of age, roofs with limited remaining lifespan.
4. Post-Atmospheric River Inspection (After Major Storms)
Timing: Within 24-48 hours after any atmospheric river event delivering 2+ inches of rain in 24 hours or sustained wind-driven rain
Why it matters: Major atmospheric rivers test roofing systems at maximum stress. Any weakness—failed flashing, compromised valleys, inadequate drainage—manifests as leaks or near-failures. Catching these immediately prevents progressive damage through the remainder of winter.
What to inspect:
- Interior ceiling and wall water stains (new or expanding)
- Attic decking for water stains or active dripping
- Gutter overflow evidence (staining on siding, soil erosion at foundation)
- Exterior flashing for separation or displacement
- Valley debris accumulation (material washed down from higher roof areas)
- Downspout discharge functionality
- Any visible exterior damage from storm
Professional inspection required if: ANY interior water intrusion, visible exterior damage, or unexplained issues after storm.
Annual Baseline Inspection
In addition to event-driven inspections, schedule comprehensive annual inspection in April (after winter rain season, before summer heat). This baseline inspection documents overall roof condition and identifies developing issues requiring monitoring or future repair.
Complete DIY Inspection Checklist: What Homeowners Can Safely Check
This checklist covers inspections you can safely perform from ground level or from attic interior. NEVER walk on your roof unless you have proper safety equipment, training, and appropriate roof type (walking on tile roofs causes damage; steep-pitch roofs require professional safety equipment).
Exterior Visual Inspection (From Ground Level)
Equipment needed: Binoculars, camera with zoom capability, notebook for documentation
Best time: Mid-morning or mid-afternoon (sun angle illuminates roof surface, shadows reveal problems)
Inspection Point 1: Overall Roof Profile
What to look for:
- Sagging areas or dips in roof line (indicates structural problems)
- Uniformity of surface (wavy or uneven appearance suggests decking issues)
- Consistent color/appearance (dramatic color changes indicate granule loss or material failure)
Red flags requiring immediate professional evaluation: Any visible sagging, dips, or significant waviness.
Inspection Point 2: Shingle/Tile Condition
For asphalt shingles, look for:
- Missing shingles: Gaps in shingle coverage (often after wind events)
- Curling edges: Shingle edges lifting or curling up (indicates aging or ventilation problems)
- Bald spots: Areas where granules have completely worn away, exposing black asphalt
- Cracked shingles: Visible cracks across shingle surface (thermal cycling damage)
- Lifted corners: Wind has broken sealant, shingle corners lifted
- Algae/moss growth: Dark streaks (algae) or green growth (moss) indicates moisture retention
For concrete/clay tiles, look for:
- Cracked or broken tiles: Visible fractures or missing tile pieces
- Displaced tiles: Tiles shifted out of position (common after wind events)
- Missing tiles: Gaps in tile coverage
- Ridge tile condition: Ridge tiles often fail first, check for displacement or missing mortar
- Exposed underlayment: Black felt or colored synthetic underlayment visible = immediate problem
Red flags: More than 5-6 damaged shingles, any exposed underlayment or decking, widespread granule loss, extensive algae/moss growth.
Inspection Point 3: Flashing Systems
Critical flashing locations to inspect:
Chimney flashing:
- Step flashing visible along chimney sides (should be properly integrated with shingles)
- Counter flashing embedded in chimney mortar (should overlap step flashing)
- Sealant condition at chimney-to-roof junction
- Any visible rust, corrosion, or separation
Pipe boot flashing:
- Rubber boots around vent pipes (look for cracks, brittleness, or complete failure)
- Metal collar under rubber boot (should be rust-free and properly sealed)
- Sealant at boot-to-pipe junction
Valley flashing:
- Metal valley visible down center of valley
- Shingle integration at valley edges (should properly overlap flashing)
- Debris accumulation in valleys
- Rust or corrosion on metal valleys
Skylight flashing:
- Flashing integration with roofing material
- Glass-to-frame seal condition
- Sealant at all junctions
- Any visible condensation between double-pane glass
Red flags: Rust on flashing, visible gaps or separations, cracked or missing rubber boots, separated sealant, any flashing that appears loose or displaced.
Inspection Point 4: Gutter System
From ground level, check:
- Gutter alignment: Should have slight slope toward downspouts, no sagging sections
- Attachment integrity: Gutters firmly attached to fascia, no pulled-away sections
- Visible debris: Leaves, branches, or sediment visible in gutters
- Downspout condition: Firmly attached, properly connected, no separations
- Discharge points: Downspouts discharge at least 6 feet from foundation
- Staining: Water stains on siding behind gutters indicates overflow issues
From ladder (if safe to access):
- Interior gutter condition (rust, holes, separated seams)
- Debris type and amount
- Downspout inlet condition (common clog point)
- Fascia board condition behind gutter (rot from overflow)
Red flags: Sagging gutter sections, visible separation from fascia, heavy debris accumulation, water stains on siding, deteriorated fascia boards.
Inspection Point 5: Roof Penetrations
Identify and inspect all roof penetrations:
- Plumbing vent pipes
- Kitchen exhaust vents
- Bathroom exhaust vents
- Furnace/water heater flues
- Satellite dishes or antennas
- Solar panel mounts (if applicable)
- HVAC equipment (rooftop units)
- Skylights
For each penetration, check:
- Flashing or boot condition
- Sealant integrity
- Proper integration with roofing material
- No visible gaps or separation
- Equipment securely mounted (dishes, antennas)
Red flags: Any visible gap or separation, cracked or missing sealant, rust stains, equipment movement or looseness.
Inspection Point 6: Chimney Condition
Beyond flashing, inspect chimney structure:
- Chimney cap: Present and undamaged (prevents water entry and animal intrusion)
- Crown condition: Concrete crown at chimney top should be intact (no major cracks)
- Brick/mortar condition: Mortar joints intact, no spalling bricks
- Leaning or movement: Chimney should be vertical and stable
- Efflorescence: White mineral deposits indicate water intrusion
Red flags: Missing chimney cap, cracked crown, deteriorating mortar, leaning chimney, significant efflorescence.
Inspection Point 7: Tree Proximity and Debris
Evaluate surrounding vegetation:
- Branches within 10 feet of roof surface (should be trimmed back)
- Overhanging branches that could fall during storms
- Dead branches posing fall risk
- Debris accumulation on roof from nearby trees
- Moss or algae growth promoted by shade/moisture
Red flags: Branches contacting roof, significant overhang, heavy debris accumulation, extensive moss growth.
Interior Attic Inspection
Safety first: Use flashlight, watch for protruding nails, avoid stepping between joists (step only on joists or installed decking), be aware of electrical wiring and insulation.
Interior Inspection Point 1: Roof Decking Underside
What to look for:
- Water stains: Dark discoloration on decking indicates current or previous leaks
- Active dripping: Water actively entering during or after rain (immediate emergency)
- Mold or mildew: Growth on decking or framing indicates chronic moisture
- Sagging decking: Indicates structural damage from water or age
- Daylight visible: Any light visible through roof indicates serious problem
Document stain locations: Photograph and note location relative to roof features visible from exterior (helps professionals locate exterior source).
Red flags: Active water intrusion, extensive staining, mold growth, visible daylight, sagging sections.
Interior Inspection Point 2: Ventilation Adequacy
Check ventilation system:
- Soffit vent airflow: Stand near eave area, feel for air movement (indicates intake working)
- Ridge vent presence: Visible from interior if installed
- Gable vents: Check for blockage or inadequate screening
- Insulation baffles: Verify insulation doesn't block soffit vent airflow
- Attic temperature: On hot day, attic should be noticeably warm but not 160°F+ extreme heat
Red flags: No visible airflow at soffits, blocked vents, extreme attic heat, condensation on underside of decking in winter.
Interior Inspection Point 3: Insulation Condition
Evaluate insulation:
- Consistent depth across attic (R-38 to R-49 recommended for Concord = 12-16 inches fiberglass/cellulose)
- No compression or gaps
- No water damage or mold
- Proper installation around penetrations
- Vapor barrier facing down (if present)
Red flags: Extensive gaps, compressed insulation, water-damaged sections, insufficient depth.
Interior Inspection Point 4: Penetration Interior Condition
From attic, inspect interior side of penetrations:
- Vent pipes: No water stains around penetration
- Chimney: Proper clearance to combustibles, no water stains
- Electrical: Proper sealing and no water damage
- Bath/kitchen vents: Properly vented to exterior (not dumping into attic)
Red flags: Water stains around any penetration, improper vent routing, inadequate clearances.
