Learn how to safely inspect your roof from the ground and identify common warning signs before they become expensive repairs. T Mix Roofing serves Portland, Beaverton, Lake Oswego, Tigard, Hillsboro and surrounding communities.
A Safe Roof Check Every Portland Homeowner Can Do
You don't need to climb a ladder to spot many of the warning signs that your roof may need attention.
At T Mix Roofing, we regularly help homeowners throughout Portland, Beaverton, Hillsboro, Tigard, Lake Oswego, Gresham, Happy Valley, Oregon City, West Linn, Milwaukie, Tualatin, Sherwood, Wilsonville, and surrounding communities identify roofing problems before they turn into expensive repairs.
In Portland's wet climate, even a small issue can quickly develop into a leak, mold growth, or structural damage. The good news? A simple ground-level inspection can help you catch problems early while keeping your feet safely on the ground.
Here's the same checklist our team recommends to homeowners.
What You Need Before You Start
You don't need special equipment.
✓ A pair of binoculars
✓ A smartphone or camera
✓ A notepad for observations
✓ Good daylight conditions
✓ A safe position away from power lines and traffic
Never climb onto a roof unless you have proper training and safety equipment. Every year, thousands of homeowners are injured from ladder and roof falls that could have been avoided.
The 5-Step Ground Inspection Checklist
Step 1: Look for Missing or Damaged Shingles
Walk around your home and inspect each roof slope.
Watch for:
• Missing shingles
• Curled shingle edges
• Cracked shingles
• Dark patches
• Uneven roof sections
In Portland, constant rain and moisture can accelerate shingle deterioration, especially on north-facing slopes where moss tends to grow.
Step 2: Check for Moss and Algae Growth
Moss is one of the most common roofing problems we see throughout the Portland metro area.
Look for:
• Green patches
• Dark streaks
• Areas where moisture seems trapped
• Thick moss growth along roof edges
Moss may seem harmless, but it can lift shingles and create pathways for water intrusion. Left untreated, it often shortens roof lifespan significantly.
Step 3: Inspect Flashing Around Roof Features
Flashing is the metal material installed around roof penetrations and transitions.
Pay special attention to:
• Chimneys
• Skylights
• Plumbing vents
• Roof valleys
• Wall intersections
If flashing appears loose, rusted, bent, or separated from the roofing material, it may allow water to enter your home.
At T Mix Roofing, flashing failures are among the most common causes of roof leaks we discover during inspections.
Step 4: Examine Gutters and Downspouts
Your gutter system tells a story about your roof's condition.
Look for:
• Sagging gutters
• Overflow stains
• Granules collecting in gutters
• Clogged downspouts
• Loose fasteners
Finding excessive shingle granules in gutters may indicate your roof is experiencing advanced wear.
Step 5: Look for Interior Warning Signs
Some roofing problems reveal themselves inside the house first.
Check your:
• Attic
• Ceiling corners
• Upper floor rooms
• Around skylights
Watch for:
• Water stains
• Mold growth
• Peeling paint
• Damp insulation
• Musty odors
These symptoms often indicate roofing problems that require professional evaluation.
