7 Signs You Need a New Roof (Indiana Homeowner Guide)

The seven signs you need a new roof are: your roof is over 20 years old, shingles are curling or buckling, you find granules in your gutters, there is daylight visible through the roof boards, your roof deck is sagging, you have recurring leaks despite repairs, and your energy bills have increased unexpectedly. If you notice two or more of these signs, schedule a professional inspection before minor issues become major structural problems.

Indiana's climate — freeze-thaw cycles, hail, heavy snow, and summer heat — ages roofs faster than the national average. A "30-year" shingle roof in Terre Haute may realistically last 20-25 years. Here is how to assess whether your roof is telling you it is time.

Sign 1: Your Roof Is Over 20 Years Old

Age is the most reliable predictor of roof condition in Indiana. Here are the realistic lifespans for common roofing materials in our climate:

If your asphalt shingle roof is approaching 20 years, it is entering the failure window regardless of how it looks from the ground. Schedule an inspection even if you do not see obvious damage. Many problems are only visible from the roof surface or inside the attic.

Do not know your roof's age? Check your home closing documents, ask previous owners, or look for a building permit record through Vigo County. A roofing professional can also estimate age based on shingle condition and style.

Sign 2: Shingles Are Curling, Buckling, or Cracking

Walk to the street and look at your roof from ground level with binoculars. Healthy shingles should lay flat and uniform. Warning signs include:

• Curling edges — shingle corners lifting away from the surface, often starting on south-facing slopes where sun exposure is highest
• Buckling — wavy, distorted shingles that create ridges along the roof surface
• Cracking — visible fractures running through shingle surfaces, caused by repeated thermal expansion and contraction
• Blistering — bubbles on the shingle surface where trapped moisture has expanded

Any of these conditions means the shingles have lost their ability to protect your home from water. Indiana's freeze-thaw cycles accelerate all of these failures — water enters the cracks, freezes, expands, and makes the damage worse with every cycle.

Sign 3: Granules Accumulating in Your Gutters

Asphalt shingles are coated with ceramic granules that protect the asphalt from UV radiation and add fire resistance. When you find significant amounts of dark, sand-like material in your gutters or at the base of downspouts, your shingles are losing their protective layer.

Normal vs. concerning: New roofs shed some excess granules for the first year. That is normal. Granule loss on a roof that is 10+ years old indicates the shingles are deteriorating and approaching end of life.

How to check: After a rain, look at the bottom of your downspout discharge areas. If you see accumulated grit that resembles coarse black sand, your roof is shedding granules. Also check gutters during routine cleaning.

Without granules, the underlying asphalt is exposed to direct UV radiation, which dramatically accelerates aging. Once granule loss reaches a visible level, the roof typically has 2-5 years of effective life remaining.

Sign 4: You Can See Daylight Through the Roof Boards

Go into your attic on a sunny day, turn off the lights, and look up at the underside of the roof deck. If you can see pinpoints of light coming through, water can get through the same openings.

While you are in the attic, also look for:

• Dark stains or streaks on the underside of the decking (evidence of past or active leaks)
• Sagging sections of decking between rafters
• Damp or soft areas when you press on the wood
• Mold or mildew growth on any surface

The attic inspection is often more revealing than looking at the roof from outside. Damage that is invisible from the ground can be obvious from below.

Sign 5: Your Roof Deck Is Sagging

A sagging roofline is a serious structural warning. Stand at the street and look at your ridge line (the peak of the roof). It should be perfectly straight. Any visible dip, wave, or sag indicates structural problems with the decking, rafters, or both.

Common causes of sagging in Indiana:

• Prolonged moisture damage from chronic leaks that weaken the decking
• Excessive weight from multiple shingle layers (Indiana code allows two, but the weight adds up)
• Inadequate ventilation trapping heat and moisture that deteriorates the wood
• Undersized framing in older homes that does not meet current snow load requirements

A sagging roof is not a "someday" problem. It is a safety hazard that requires prompt professional evaluation. If the sag is significant, the roof could be at risk of partial collapse under heavy snow load.

Sign 6: Recurring Leaks Despite Repairs

If you have had the same area repaired multiple times and it keeps leaking, the problem is almost certainly systemic rather than localized. Common systemic causes include:

• The underlayment has failed across a wide area, not just the patched spot
• Flashing around chimneys, skylights, or vents has corroded through
• The roof deck has moisture damage that spreads outward from the original leak point
• The shingles have reached end of life and patching one area does not stop water from entering adjacent failing areas

The repair vs. replace rule of thumb: If repair costs over the past five years total more than 30% of a replacement cost, or if you have had three or more repairs to the same general area, replacement is the more cost-effective choice. Read our detailed repair vs. replacement guide for a complete decision framework.

Sign 7: Unexplained Increase in Energy Bills

A failing roof compromises your home's thermal envelope. When shingles deteriorate, underlayment breaks down, and ventilation fails, your attic becomes a heat sink in summer and a cold sink in winter. The result is higher HVAC costs.

Signs that your roof is affecting energy efficiency:

• Summer cooling bills increased 15-25% compared to previous years (same usage patterns)
• Upper floors are noticeably hotter in summer or colder in winter than lower floors
• Ice dams forming along eaves in winter (indicates heat escaping through the roof)
• Attic temperature exceeding 150°F in summer (check with an inexpensive thermometer)

A new roof with proper ventilation and modern underlayment can reduce energy costs by 10-25%, partially offsetting the replacement cost through monthly savings.

What Should You Do If You See These Signs?

Do not panic, and do not rush into a decision. Follow these steps:

1. Document what you see. Take photos from the ground and in the attic.
2. Schedule a professional inspection. A qualified roofer can assess the full picture, including areas you cannot safely access. Elite Roofing offers free inspections across Terre Haute and 14 surrounding cities.
3. Get multiple opinions. If one contractor says full replacement and the situation seems borderline, get a second opinion.
4. Understand your options. Sometimes a partial repair or overlay makes sense. Sometimes full replacement is the only responsible choice. An honest contractor will explain the tradeoffs clearly.
