You can catch the majority of developing roof problems without climbing a ladder or hiring anyone. A pair of binoculars, a flashlight, and 30 minutes twice a year will tell you more about your roof's condition than most homeowners ever learn. This checklist covers 13 specific items organized by where you are checking — outside from the ground, in the attic, and from inside your home.

Exterior Inspection (From the Ground)
Grab a pair of binoculars and walk the perimeter of your home. You want to examine each roof face from multiple angles. Morning or late afternoon light is best — the low angle creates shadows that reveal surface irregularities. Stand across the street to check the ridgeline. Do this slowly and systematically, one roof face at a time.
What to look for: Scan each roof face with binoculars. Look for gaps, broken pieces, or shingles that appear to be lifting or flapping.
What it means: Exposed underlayment or decking. Even one missing shingle is a potential entry point for water.
What to look for: Edges turning upward (curling) or middles pushing upward creating a wavy appearance (buckling).
What it means: Aging material, poor ventilation, or moisture trapped beneath the shingles. These shingles are more vulnerable to wind lift.
What to look for: Black or dark green streaks running vertically down the roof. Extremely common on Gulf Coast roofs.
What it means: Algae growth (Gloeocapsa magma). Mostly cosmetic, but heavy accumulation can hold moisture and accelerate granule loss over time.
What to look for: Stand across the street and sight along each ridge line and roof plane. Any visible dip, bow, or sag.
What it means: Structural compromise — damaged decking, failed rafters, or prolonged moisture damage. This is never cosmetic.
What to look for: Look at where the roof meets the chimney, walls, and any visible vent pipes. Check for rust, gaps, or pieces that appear loose or displaced.
What it means: Failed flashing is one of the most common leak sources on Gulf Coast homes, especially in coastal areas where salt air corrodes metal.
What to look for: Check gutters for heavy granule accumulation (sandy grit), sagging sections, pulled-away fasteners, and proper water flow during rain.
What it means: Heavy granules indicate shingle deterioration. Sagging gutters can pull away fascia boards and create water entry points at the roof edge.
Attic Inspection
You need a flashlight, clothing you do not mind getting dirty, and careful footing. Step only on rafters or joists — never on the drywall between them, which will not support your weight. If your attic is unfinished with blown insulation, the joists may be hidden. Take your time and be careful. If access is difficult or you are uncomfortable, this is the section to leave to a professional.
Safety first: on the Gulf Coast, attics get dangerously hot. From May through October, attic temperatures can exceed 140 degrees. Schedule your attic check for early morning or during cooler months. Heat exhaustion in a confined attic space is a real risk. If the attic feels oppressively hot when you open the hatch, come back another day.
What to look for: Turn off the attic light and let your eyes adjust. Look for any pinpoints of light coming through the roof surface.
What it means: Direct openings in the roof — holes, gaps, or displaced materials. Every point of light is a potential leak path.
What to look for: Look at the underside of the roof decking and along rafters for dark stains, discoloration, or visible water trails.
What it means: Water has entered the roofing system at some point. Fresh stains (dark, damp) indicate an active issue. Old stains (light, dry) indicate a past event that may or may not have been resolved.
What to look for: Feel the insulation — is it damp? Look for any green, black, or white fuzzy growth on wood surfaces. Notice any musty or earthy smell.
What it means: Ongoing moisture intrusion or condensation problem. Mold in the attic is a health concern and indicates that the moisture source needs to be identified and stopped.
What to look for: Is insulation evenly distributed? Are there compressed, displaced, or missing sections? Is it damp anywhere?
What it means: Displaced insulation may indicate animal activity, prior repairs, or water damage. Compressed insulation loses R-value. Damp insulation points to a moisture source above.
Interior Inspection (Top Floor)
Walk through every room on the top floor of your home. Look up. This is the simplest part of the checklist and it catches problems that have already progressed to the point of affecting your living space. Any finding here means the problem has been developing for a while — water had to travel through the attic and into the ceiling or walls before becoming visible.
What to look for: Walk through every room on the top floor. Look at ceilings for brown, yellow, or tan spots, rings, or streaks.
What it means: Water reached the drywall from above. The source could be a roof leak, plumbing issue, or condensation. Location relative to bathrooms and roof penetrations helps narrow the cause.
What to look for: Check walls and ceilings near the roof edges, especially in rooms below the eaves. Look for bubbling, peeling, or flaking paint.
What it means: Moisture is reaching the interior wall or ceiling surface. Often indicates a flashing failure at the roof-to-wall transition or inadequate ventilation.
What to look for: Notice any persistent damp or musty odor in rooms directly below the attic, especially in closets or bathrooms on the top floor.
What it means: Hidden moisture problem — likely in the attic space above. The smell may be more noticeable during humid weather or after rain.
Gulf Coast Post-Storm Additions
After any named storm or severe weather event, run through the full checklist above plus these additional items. Hurricane and tropical storm damage can be subtle, and documenting everything quickly protects both your home and your insurance claim options.
Additional Post-Storm Checks
- Debris impact marks: Look for dents, cracks, or punctures caused by flying debris. Check all roof faces, not just the windward side — debris travels in unpredictable patterns during hurricanes.
- Ridge cap displacement: The ridge cap (the row of shingles along the peak) is the most wind-vulnerable part of the roof. Even minor displacement can allow water intrusion. Use binoculars to check whether the ridge line looks continuous and even.
- Soffit and fascia damage: High winds can tear soffit panels loose, exposing the attic to rain that enters sideways under the eaves. Walk the perimeter and look up at the underside of each overhang.
- Gutter displacement: Storms can pull gutters away from the fascia or fill them with debris that creates standing water. Standing water at the roof edge accelerates rot at the most vulnerable junction of the roofing system.
- Neighbor comparison: If neighboring homes have visible damage — tarps, missing shingles, contractor trucks — your roof was hit by the same storm. The absence of visible damage on your roof does not mean the absence of damage. Hidden wind damage is common and requires close inspection.
Document everything with dated photos immediately. Gulf Coast insurance policies have strict timelines for filing storm damage claims. In Florida, the statute of limitations on property insurance claims is tight and has been getting tighter. Having photographic evidence from the day after the storm is significantly more valuable than photos taken weeks later.
When Your Findings Mean It's Time to Call a Professional
This checklist helps you monitor and catch problems early. Some findings are things you can track over time. Others require professional assessment. Here is the dividing line.
Call a professional this week if: you see sagging in the roofline, daylight is visible through the roof in the attic, you find active moisture or mold in the attic, ceiling stains are wet or growing, or you have multiple urgent-severity findings from the checklist above.
Schedule a professional inspection within the next few months if: you have moderate-severity findings that you want confirmed, your roof is over 15 years old and you have not had a professional inspection recently, you are seeing gradual changes between your self-inspections, or you want a documented baseline before hurricane season.
Continue self-monitoring if: all findings are cosmetic or low-severity, the roof is under 10 years old with no symptoms, and nothing has changed since your last self-inspection. Run through this checklist every six months — once in spring before hurricane season, once in fall after.
During your self-inspection, you find heavy granules in the gutters, two ceiling stains on the top floor (both dry), and your 18-year-old architectural shingle roof has dark algae streaks across the north face. What is the appropriate next step?
Reveal answer
Schedule a professional inspection within the next month. The combination of heavy granule loss and dry ceiling stains on an 18-year-old roof tells a story: the shingles are deteriorating (granule loss), water has gotten in at some point (ceiling stains), and the roof is approaching or past its Gulf Coast-adjusted lifespan for architectural shingles (18–25 years). The algae streaks are cosmetic and expected. The other two findings together warrant professional evaluation to determine remaining useful life and whether the leak sources have been resolved.
