Homeowner safely inspecting roof from a ladder

Your roof is one of the most critical components of your home, providing protection against weather elements and contributing significantly to your property's structural integrity and energy efficiency. While professional roof inspections are recommended annually, homeowners can perform basic inspections between professional visits to identify potential issues before they develop into costly problems. This guide will walk you through a safe and effective DIY roof inspection process.

Safety First

Before we dive into inspection techniques, it's crucial to emphasize safety. Roof accidents can be serious or fatal. This guide focuses primarily on inspections that can be conducted from the ground, ladders, or inside your home. If you're uncomfortable with heights, have physical limitations, or if your roof has a steep pitch, please hire a professional rather than risking injury.

When to Inspect Your Roof

Regular roof inspections help catch problems early. Consider conducting DIY inspections:

  • Seasonally: Especially after winter and before fall to prepare for extreme weather
  • After major storms: High winds, heavy rain, hail, or significant snowfall can damage roofing materials
  • When buying a home: Always check the roof condition thoroughly, even if the seller has provided an inspection report
  • If you notice interior signs of leaks: Water stains on ceilings or walls warrant immediate investigation

Ground-Level Inspection

Many roofing issues can be spotted from ground level using binoculars, which is the safest approach for homeowners.

What You'll Need

  • Binoculars
  • Camera or smartphone to document findings
  • Notepad or digital device to record observations

What to Look For

Walk around your home's perimeter and look for these signs of potential problems:

For Asphalt Shingle Roofs:

  • Missing, curled, or buckled shingles: These expose your roof to water damage
  • Excessive granule loss: Bald spots on shingles reduce their weather resistance
  • Uneven roof surface: Sagging or waviness in the roofline can indicate structural issues
  • Dark streaks: Often a sign of algae growth, which can deteriorate roofing materials over time
  • Moss growth: Traps moisture against the roof and can lead to premature deterioration

For Metal Roofs:

  • Rust or corrosion: Particularly at panel edges or around fasteners
  • Loose or missing fasteners: Can lead to panel movement during high winds
  • Dents or punctures: May be caused by hail or falling branches
  • Panel separation: Gaps between panels can allow water intrusion

For All Roof Types:

  • Flashing issues: Look for damaged, rusted, or missing flashing around chimneys, vents, and roof transitions
  • Gutter problems: Check for sagging, detachment, or overflow during rainfall
  • Debris accumulation: Leaves, branches, and other debris can trap moisture and block drainage
  • Chimney concerns: Cracks, deteriorating mortar, or tilting chimneys require professional attention

Ladder Inspection

A closer look from a ladder can reveal issues not visible from the ground, but requires extra caution.

Ladder Safety Tips

  • Use a sturdy ladder that extends at least three feet above the roof edge
  • Have a helper hold the ladder base while you climb
  • Maintain three points of contact (two hands and one foot, or two feet and one hand) at all times
  • Never lean too far to either side – move the ladder instead
  • Avoid ladder use during windy, rainy, or icy conditions
  • Keep the ladder away from power lines

From the Ladder Edge

Position your ladder securely against the gutter or eave at multiple points around your home. Do not step onto the roof itself unless you have proper safety equipment and experience. From the ladder, examine:

  • Gutter condition: Check for proper attachment, debris accumulation, and signs of rust or deterioration
  • Shingle edges: Look for lifting, curling, or damage at roof edges
  • Fascia and soffit: Inspect for rot, peeling paint, or animal intrusion
  • Edge flashing: Ensure it's properly secured and not pulling away from the roof
  • Drip edge: Verify it's directing water into the gutters properly

Attic Inspection

Perhaps the most overlooked aspect of roof inspection is examining your attic, which can reveal problems before they become visible from outside.

When to Check Your Attic

The best time to inspect your attic is during daylight hours after or during rainfall when leaks are most apparent. However, regular checks in dry weather are also valuable.

What You'll Need

  • Flashlight or headlamp
  • Dust mask (attics can contain insulation particles and dust)
  • Gloves
  • Appropriate footwear with good traction
  • Wooden boards to walk on (if your attic doesn't have proper flooring)

What to Look For

  • Water stains or discoloration: On rafters, sheathing, or insulation
  • Mold or mildew: Dark spots or fuzzy growth indicating moisture issues
  • Daylight showing through: Small pinpoints of light indicate holes in your roof
  • Sagging sheathing: This can indicate structural problems or long-term water damage
  • Ventilation issues: Check that soffit and ridge vents are unobstructed
  • Insulation condition: Look for compression, water damage, or uneven distribution
  • Animal intrusion: Droppings, nests, or chewed materials

Tracing Leaks

Water often travels from its entry point before becoming visible, making leak sources tricky to identify. If you spot water stains:

  1. Follow stains upward to their highest point
  2. Look for corresponding exterior issues above this area
  3. Consider that water might be entering around roof penetrations (vents, chimneys) some distance from the visible interior damage

Key Areas to Focus On

Certain areas of your roof are more prone to problems and deserve special attention:

Roof Valleys

These are the V-shaped intersections where roof planes meet. Valleys channel large volumes of water and are common leak points. Look for:

  • Damaged or missing valley flashing
  • Debris accumulation that could block water flow
  • Deteriorated or missing shingles along the valley edges

Roof Penetrations

Any object that protrudes through your roof creates a potential entry point for water. Carefully inspect around:

  • Vents and pipes: Check that boots (the rubber seals around pipes) aren't cracked or deteriorated
  • Chimneys: Examine flashing and masonry for damage or deterioration
  • Skylights: Look for proper flashing and signs of leakage around the perimeter
  • Satellite dishes or antennas: Ensure mounting hardware hasn't created holes or damage

Edges and Transitions

Areas where the roof meets walls or changes direction require special attention:

  • Step flashing: Where the roof meets walls
  • Eaves and rakes: The edges of your roof
  • Dormers: Where vertical walls intersect with the roof plane

Documenting Your Findings

Creating thorough documentation during your inspection will help you track changes over time and provide valuable information if you need to consult a professional:

Creating a Roof Inspection Report

  1. Take dated photographs: Document general roof condition and specific areas of concern
  2. Create a simple diagram: Mark the location of any issues you find
  3. Keep notes: Describe problems in detail, including their location and severity
  4. Track changes: Compare current conditions to previous inspections

What to Include in Your Documentation

  • Date of inspection
  • Weather conditions
  • Areas inspected
  • Specific issues found
  • Photos of each problem area
  • Recommendations for follow-up

When to Call a Professional

While DIY inspections are valuable, certain situations call for professional expertise:

Red Flags That Require Immediate Attention

  • Active leaks: Water coming into your home needs immediate professional assessment
  • Structural concerns: Sagging roof sections, shifted rafters, or cracked structural members
  • Extensive damage: Multiple missing shingles, large damaged areas, or widespread deterioration
  • Recent severe weather: After major hailstorms, hurricanes, or tornados
  • Age-related issues: Roofs nearing or past their expected lifespan
  • Insurance claims: Most claims require professional documentation

The Value of Professional Inspections

Even if you perform regular DIY inspections, professional assessments offer important benefits:

  • Trained eyes that can spot subtle issues
  • Experience in identifying the root causes of problems
  • Safe access to all roof areas
  • Detailed documentation for insurance or warranty purposes
  • Expert recommendations for repairs or maintenance

Simple Maintenance You Can Perform

During your inspections, you might identify minor issues you can safely address yourself:

Safe DIY Maintenance

  • Gutter cleaning: Remove leaves and debris to ensure proper drainage
  • Trim overhanging branches: Prevents debris accumulation and potential damage during storms
  • Remove debris: Sweep or blow off accumulations of leaves, branches, or other debris
  • Clear snow: Using a roof rake from ground level to prevent ice dams (never climb onto a snow-covered roof)
  • Ensure attic ventilation: Check that vents aren't blocked by insulation or debris

Tasks to Leave to Professionals

  • Replacing shingles or roofing materials
  • Repairing or replacing flashing
  • Addressing structural issues
  • Applying coatings or sealants
  • Installing or repairing roof penetrations

Creating a Roof Maintenance Calendar

Developing a routine inspection and maintenance schedule helps ensure your roof gets the attention it needs throughout the year.

Suggested Inspection Schedule for Canadian Homes

  • Spring (March-April): Check for winter damage, clean gutters of debris
  • Summer (July-August): Look for sun damage, cracked caulking, or heat-related issues
  • Fall (October-November): Clear leaves, check for potential issues before winter, ensure drainage systems are working
  • After major storms: Conduct a targeted inspection focusing on vulnerable areas

Maintenance Timing

Schedule maintenance and repairs during favorable weather conditions. In Canada, the ideal months for roof work are typically May through September, when temperatures are moderate and major storms are less likely.
