Diagnose Your Roof Problem
Eight of the most-searched residential roof problems, with the likely causes, a self-check, and the conditions that mean you should call a licensed local roofer right now.
(844) 578-3077 — Call to Get MatchedActive Roof Leak Or Water Spots On The Ceiling
Water entering your home through the roof is the most common emergency call. The leak point inside is usually several feet away from where the water entered the roof, because water runs along rafters and decking before dripping down. Diagnosis starts at the interior stain and works back to the exterior source.
Likely causes
- Failed flashing around a chimney, vent stack, or skylight (most common, especially on roofs over 10 years old)
- Cracked or missing shingles after a recent wind event
- Clogged valley backing water under shingles during heavy rain
- Cracked pipe boot rubber gasket (very common at 10+ years)
- Ice dam in cold-climate homes during freeze-thaw cycles
- Inadequate roof deck ventilation causing condensation
Self-check before you call
- 1Contain the active drip with buckets and move valuables away
- 2Climb into the attic if safe and trace the water path back to the rafters
- 3From the ground, scan the roof for missing shingles or visible debris
- 4Check that exterior gutters and downspouts are not overflowing
- 5Note any recent storms, hail, or fallen tree limbs
Call a local roofer if
- Water is actively dripping during or right after rain
- Daylight is visible through the roof deck in the attic
- Mold smell or bulging drywall appears upstairs
- Multiple leak points are appearing across the ceiling
- Your roof is over 15 years old and this is the second leak this year
Shingles Missing, Curling, Or Cracked
Missing, curling, or cracked shingles signal that the roof has lost its outer water-shedding layer in spots. Causes vary: storm wind, age, manufacturer defect, or improper original install. Even a single missing shingle exposes the underlayment to UV and water — fix it before the next storm.
Likely causes
- High-wind event blowing shingles off (especially edges and ridges)
- Age-related shingle curl as the asphalt loses oils (10+ year roofs)
- Granule loss exposing the underlying mat, then cracking
- Improper nailing on the original install (nails too high, too few)
- Manufacturer defect on early-generation shingles (look for class-action history)
Self-check before you call
- 1Walk the property perimeter looking for shingles on the ground
- 2Use binoculars or a phone-camera zoom to scan the roof from the ground
- 3Check downspout exits for accumulated shingle granules (large amounts = aging roof)
- 4Note whether damage is isolated to one slope or scattered (storm vs age)
Call a local roofer if
- More than 3-5 shingles are missing — exposed area is too large to safely wait
- Damage covers a large area of one slope (likely storm event with insurance claim)
- Underlayment (black paper) is visible from the ground
- Roof is approaching 20 years old and you're seeing widespread granule loss
Hail Damage Signs You Can Check From The Ground
Hail damage is the most-claimed roof insurance event and the hardest to spot. Most insurance claims need to be filed within 1 year of the storm — and adjusters get stricter as time passes. If you experienced a hail event, document immediately even if the roof looks fine, because hail damage shows up months later as accelerated granule loss and leaks.
Likely causes
- Hailstones 1"+ in diameter can damage asphalt shingles
- Soft metal damage on gutters, downspouts, AC fins, and vent caps is the easiest ground-level indicator
- Bruising on shingles (impact spots where granules dislodged but no crack yet)
- Cracked or shattered tiles on tile roofs (visible from the ground)
- Dented metal panels on metal roofs
Self-check before you call
- 1Check downspouts and gutters for dents or dings
- 2Look at the AC condenser fins outside — dented fins indicate hail size and force
- 3Inspect vent caps and roof flashings (visible from upstairs windows or with binoculars)
- 4Photograph everything immediately with timestamp
- 5Contact your insurance carrier within 48 hours of the storm to start the documentation clock
Call a local roofer if
- A hail event hit your area in the last 30 days and your roof is over 5 years old
- Insurance adjuster has scheduled an inspection (a roofer should attend to document damage they see)
- You're seeing accelerated granule loss in the months after a hail event
- Active leaks have appeared post-hail (delayed leak development is common)
Ice Dam Or Icicles On The Roof Edge
Ice dams form when heat escapes from the attic, melts snow on the upper roof, then refreezes at the cold eave. The dam blocks new meltwater, which backs up under shingles and into the attic and walls. Ice dams cause some of the most expensive interior water damage in cold-climate homes and almost always trace back to attic insulation and ventilation problems.
Likely causes
- Inadequate attic insulation (R-38 or higher recommended in cold climates)
- Poor attic ventilation (warm attic air can't escape)
- Bathroom or kitchen fans venting into the attic instead of outside
- Recessed lighting fixtures leaking heat into the attic
- Snow accumulation on a roof that needs to be removed
Self-check before you call
- 1Check for icicles forming at the eaves (the visible symptom)
- 2Look in the attic for moisture at the underside of the roof deck near eaves
- 3Inspect ceiling stains near exterior walls (interior water-damage symptom)
- 4Measure attic insulation depth — under 10" is typically inadequate in cold climates
- 5Verify that bathroom/kitchen vents exit outside, not into the attic
Call a local roofer if
- Active water staining on ceilings near exterior walls during winter
- Ice dam is more than 1-2 inches thick and the forecast shows continued snowfall
- You can see ice working back under the shingles (visible from a window above)
- Repeated ice-dam seasons — the underlying insulation/ventilation issue needs a real fix
Sagging Roofline Or Structural Concerns
A sagging roofline indicates structural failure — typically rafters, trusses, or the ridge beam. This is rarely from the shingle layer; it's from the wood underneath. Sagging can be from age, prolonged moisture damage, or being overloaded by snow or a previous re-roof that added weight without structural reinforcement.
Likely causes
- Long-term moisture damage rotting rafters or sheathing
- Snow-load overload exceeding structural capacity
- A re-roof that added significant weight (e.g., shingle over tile) without reinforcement
- Termite or carpenter-ant damage to roof framing
- Original construction error — undersized rafters or improper truss connections
- Foundation settlement transferring to the roof structure
Self-check before you call
- 1View the ridge line from across the street — should be perfectly straight
- 2From inside, check whether interior doors near load-bearing walls have begun to stick
- 3Look in the attic for cracked, split, or bowed rafters
- 4Check for moisture, mold, or insect damage on the roof framing
Call a local roofer if
- Sag is visibly progressing (compare to photos from 6 months ago)
- Visible cracks in load-bearing rafters or trusses
- Recent heavy snowfall or wind event preceded the sag
- Sag is over 1-2 inches across the ridge (significant structural concern)
Large Amounts Of Shingle Granules In Gutters
Asphalt shingles shed some granules naturally throughout their lifespan, but heavy accumulation in gutters signals accelerated aging or storm damage. The granules protect the asphalt from UV — once they're gone, the shingle dries out, cracks, and fails. Granule accumulation is a leading indicator of needed replacement.
Likely causes
- End-of-life aging on a roof 15-25 years old (normal for older roofs)
- Recent hail event dislodging granules in concentrated areas
- Heat damage in hot climates accelerating granule loss
- Manufacturer defect on early-2000s shingles (some class-action history)
- Pressure-washing damage from a previous cleaning attempt
Self-check before you call
- 1Scoop accumulated granules from gutters — small handful per cleaning is normal, multiple cups is accelerated wear
- 2Inspect shingles from the ground or upstairs window for bald spots or color change
- 3Check the age of your roof against manufacturer's expected lifespan
- 4Note whether granule loss is concentrated (storm-related) or sitewide (age-related)
Call a local roofer if
- Multi-cup granule accumulation after each rain on a 15+ year old roof
- Visible bald spots on shingles from the ground
- Color change visible on shingles (lighter color where granules are missing)
- Recent hail event preceded the increased granule loss
Storm Or Wind Damage Assessment
After a major storm, your roof may have damage that's invisible from the ground. Most insurance policies require notification within 30-60 days of the damage event, so even a precautionary post-storm inspection has real value — it preserves your claim window and catches issues before they leak.
Likely causes
- Sustained winds over 50 mph lifting and cracking shingles
- Microburst or tornado damage (concentrated, usually on one slope)
- Tree limb impact (visible debris on roof or in yard)
- Wind-driven hail damaging shingles, flashings, and vent caps
- Lightning strike damage (rare but possible, look for charring or cracked masonry)
Self-check before you call
- 1Walk the property perimeter looking for shingles, tile fragments, or roof debris
- 2Scan visible roof slopes from the ground with binoculars or a phone-camera zoom
- 3Check soffits and fascia for impact damage
- 4Inspect the attic for new water staining or daylight
- 5Photograph everything before any cleanup begins
Call a local roofer if
- Any visible roof damage after a wind event over 50 mph
- Hail event over 1" diameter hit your area in the past 30 days
- Tree limb fell on or against the roof (even if no visible damage)
- Active leak appeared during or after the storm
- Insurance adjuster has scheduled — have a licensed roofer attend the inspection
Is It Time To Replace? A Roof-Age Diagnostic
Most roofing materials have predictable lifespans, but real-world factors — sun exposure, ventilation, install quality, climate — shift outcomes by 5-15 years. If your roof is approaching the lower end of its expected range, get a professional inspection. Catching end-of-life early lets you replace on your timeline (instead of in the middle of a leak emergency).
Likely causes
- Asphalt shingle lifespan: 15-30 years (climate-dependent)
- Architectural shingle lifespan: 20-30 years
- Tile (clay/concrete) lifespan: 40-70+ years (but underlayment needs replacement every 20-25 years)
- Metal lifespan: 40-70 years (paint warranty 30-40)
- Wood shake lifespan: 20-30 years (with maintenance)
- Modified bitumen / built-up flat: 15-30 years
Self-check before you call
- 1Check your home's records or last inspection report for the original install date
- 2Inspect shingle condition: cracking, curling, granule loss = end-of-life signals
- 3Check the deck condition from the attic (sagging, soft spots, moisture stains)
- 4Note ventilation: undervented attics shorten roof life by 5-10 years
- 5Count recent leaks: 2+ in a year on an older roof signals the start of widespread failure
Call a local roofer if
- Roof is at or past expected lifespan and you're seeing failure signs
- You're planning to sell within 2 years (a new roof is one of the highest-ROI pre-sale investments)
- You've had 2+ leaks in the past 18 months
- Visible deck rot or sagging is evident in the attic
- Insurance carrier flagged the roof during a renewal inspection
