Roof Inspection Checklist: A Simple Guide for Knoxville Homeowners

Your roof is more than just shingles and gutters, it’s your home’s first line of defense against Tennessee’s unpredictable weather. From pop-up summer storms to winter snow and ice, Knoxville homes face year-round roofing challenges.

At Garrett Roofing, we believe prevention is the best protection. That’s why we offer free roof inspections and encourage homeowners to keep an eye out for early signs of damage. Whether you’re in North Knoxville, Powell, Farragut, or anywhere in East Tennessee, this guide will help you spot problems before they become expensive repairs.

Why Use a Roof Inspection Checklist?

A regular inspection can:

• Catch problems early before they escalate into leaks or structural damage

• Extend your roof’s lifespan through proactive roof maintenance

• Ensure insurance compliance and smooth claims processing

• Improve energy efficiency and indoor comfort

• Protect your home’s value by preventing mold, staining, and interior water damage

Start Your Roof Inspection 

You don’t have to climb a ladder or walk your roof to get started. Grab a pair of binoculars, a notepad, and this checklist. If you’re not comfortable inspecting certain areas, leave it to our professionals. Request a Free Roof Inspection.

Shingles and Surface Condition

Look For:

• Missing, curling, or cracked shingles

• Bald spots or granules collecting in gutters or near downspouts

• Uneven patches or color streaks

Why It Matters:
Damaged or aging shingles can allow water to penetrate the underlayment, leading to rot, mold, or even interior leaks.

Flashing Around Chimneys and Vents

Look For:

• Loose or corroded metal flashing

• Cracked caulking or sealants

• Gaps where flashing separates from surfaces

Why It Matters:
Flashing is one of the most common areas where leaks start—especially after a storm or cold snap.

Interior Water Stains or Moisture

Look For:

• Water stains on ceilings or walls

• Mold or mildew in attic spaces

• Sagging insulation or visible light through the roof boards

Why It Matters:
These are signs that water has already made it past the roofing surface—and damage is underway.

Gutters and Drainage Systems

Look For:

• Clogged or sagging gutters

• Rust, holes, or separated seams

• Improperly angled downspouts or pooling water near the foundation

Why It Matters:
Roof drainage problems cause water to back up under shingles or overflow onto siding and trim—leading to rot and mold.

5. Moss, Algae, and Streaking

Look For:

• Green moss, black streaks, or lichen growing in shaded areas

• Slippery patches or buildup at valleys

Why It Matters:
Algae and moss hold moisture against your roof, leading to premature wear and long-term damage, especially in Knoxville’s humid summers.

Roof Penetrations and Skylights

Look For:

• Loose vent boots

• Damaged or lifted skylight seals

• Cracked glass or moisture inside skylight panes

Why It Matters:
Every hole in your roof is a potential leak. These areas need proper flashing and sealing to stay watertight.

Storm or Wind Damage

Look For:

• Tree limbs on or near the roof

• Torn shingles, dents, or scattered debris

• Missing ridge caps or blown-off sections

Why It Matters:
East Tennessee storms are fast-moving and strong, and damage isn’t always obvious from the ground but can weaken your roof’s structure.
