You don't need to climb on your roof to spot most problems. This DIY inspection checklist teaches Tampa homeowners what to look for from the ground, in the attic, and around the perimeter — and when it's time to call a pro.

Most Tampa Bay homeowners know they should inspect their roof regularly, but few actually do it. The reasons are understandable — it sounds dangerous, technical, and time-consuming. But here's the truth: you can catch 80% of roof problems without ever stepping on a ladder. A thorough ground-level and attic inspection takes about 30 minutes and can save you thousands by catching issues early.
After inspecting thousands of roofs across Tampa Bay, we've built this DIY checklist to help homeowners evaluate their own roof's condition. We'll walk you through what to look for, what's normal, and when you need to pick up the phone and call a professional.
Grab a pair of binoculars and walk slowly around your entire home. You're looking at the roof from every angle, taking note of anything that looks uneven, damaged, or out of place.
Scan each visible section of your roof for shingles that are curling, buckling, cracked, or missing entirely. Curling edges are one of the earliest signs of aging — when shingles curl, they lose their wind resistance and become vulnerable to blow-off during Tampa Bay's frequent storms. Also look for areas where the shingle color is inconsistent, which may indicate patches from previous repairs that don't match or areas where granule loss is more advanced.
Step back and look at your roofline from a distance. It should be straight and even. Any sagging, dipping, or waviness suggests structural issues underneath — potentially water-damaged decking or failing rafters. This is especially common in older Tampa Bay homes that have weathered decades of tropical storms.
A sagging roofline is never cosmetic. It indicates structural failure that will worsen over time. If you notice sagging, contact a licensed roofing contractor immediately.
Look at the metal flashing around chimneys, vents, and where the roof meets walls. With binoculars, you can often see if flashing is lifted, rusted, or has gaps. Also check the drip edge along the roof perimeter — missing or bent drip edge is a common finding on Tampa Bay homes and allows water to run behind the gutters and rot the fascia.
Black streaks on your roof are almost always algae (Gloeocapsa magma), which is extremely common in Tampa Bay's warm, humid climate. While algae itself doesn't cause immediate structural damage, it feeds on the limestone in your shingles and accelerates wear. Green moss is more concerning — it retains moisture and can lift shingle edges. Any growth on the north-facing slopes of your roof should be monitored closely.
Walk the perimeter of your home and look at everything between the ground and the roofline.
Check your gutters for shingle granules — the small, sand-like particles that coat the surface of asphalt shingles. Some granule loss is normal, especially on new roofs. But if your gutters are full of granules, your shingles are losing their protective coating faster than normal. This is a sign your roof is approaching end of life. Also look for debris buildup that could cause overflow during Tampa's heavy rains.
Examine the fascia boards (the vertical trim behind the gutters) and soffit panels (the horizontal underside of the roof overhang). Look for peeling paint, soft spots, holes, or visible rot. In Tampa Bay's humidity, wood fascia deteriorates quickly once the protective finish fails. Also check that soffit vents aren't blocked by paint, debris, or wasp nests — proper ventilation is critical for roof longevity and energy efficiency.
Water stains, peeling paint, or mold growth on exterior walls just below the roofline often indicate gutter overflow or flashing failure. These symptoms show up on the walls long before a leak appears inside your home, making them valuable early warning signs.
The attic inspection is where you'll find problems that aren't visible from outside. Go on a sunny day so natural light can help you spot issues.
Turn off any attic lights and look for daylight coming through the roof deck. Any visible light means there's a gap in your roof system. Also scan the underside of the decking for water stains — they appear as dark rings or discoloration. In Florida, even small leaks create conditions for rapid mold growth, so stains should never be ignored.
Check your attic insulation. It should be dry, evenly distributed, and at the depth recommended for Florida (R-30 to R-38, or about 10-14 inches of blown fiberglass). Wet, compressed, or moldy insulation is a red flag for an active leak. Also look for areas where insulation has been disturbed by pests — rats, squirrels, and raccoons are common attic invaders in Tampa Bay.
On a warm day, you should feel air moving in your attic — entering through the soffit vents and exiting through the ridge or gable vents. If the air feels stagnant and oppressively hot, your ventilation system isn't working properly. This accelerates shingle deterioration from the underside and dramatically increases cooling costs.
After completing your inspection, rate your roof based on what you found:
Take photos during every inspection and save them with the date. These before-and-after records are invaluable if you ever need to file an insurance claim after a storm.
A DIY inspection is great for catching obvious problems and monitoring known issues. But it has limitations. A professional inspector will check things you can't safely access — roof penetration seals, underlayment condition, nail patterns, and structural integrity of the deck. We recommend a professional inspection at least once every 2-3 years for roofs under 10 years old, and annually for roofs older than that.
Regular roof inspections — whether DIY or professional — are one of the smartest things you can do as a Tampa Bay homeowner. Catching problems early means smaller repairs, lower costs, and a roof that protects you through every storm season.
