Over time, the combination of sun, heat, and moisture can take a serious toll on your roof. While metal and tile roofs often outlast asphalt shingles, no material is immune to the damage caused by severe weather, temperature swings, or falling tree limbs.
Because roof replacement is one of the most significant investments you’ll make in your home, it’s worth exploring whether repairs can extend your roof’s lifespan before committing to a full re-roof.
To help you decide, we’ve outlined the top warning signs that could mean your roof is nearing the end of its service life. In many cases, catching these issues early could save you from needing a full replacement.
Key signs to watch
Noticeable damage to shingles or roof decking after storms or high winds
Worn or cracked flashing around chimneys, vents, or valleys
Water stains on ceilings or signs of interior leaks
Key signs for a shingle roof
Missing, curling, or cupping shingles
Shingles with surface blisters or exposed black asphalt
Bare patches where protective granules have worn away
Let’s take a deeper dive into the key signs that you need a new roof. Roof repair and replacement is challenging, so you'll want to be sure you're making the right call before taking on the investment. Whether you’re dealing with storm damage, old shingles, or leaks creeping into your attic, knowing what to look for can save you money and prevent larger issues down the road. Below are the most common warning signs that it might be time to call a trusted roofing contractor.
Water Leaks
Water leaks is the worst-case scenario and should be addressed immediately. Leaks from the roof can immediately damage your home and can lead to significant structural damage to your home. Water leaks can also introduce mold and mildew. Address any type of roof leak immediately and thoroughly.
Curled Shingles
Curled asphalt shingles or cupped shingle tabs are a great indicator of a few critical issues, including improper installation or poor attic ventilation. It is important to have a professional check your roof to see if these problems can be corrected before damage is done. To see the types of shingles we offer, check out our featured shingle materials
Cracked/Ripped Shingles
Cracked or ripped shingles is a tell-tale sign that you're in need of roof repair.
Missing or Damaged Granules
Bald patches on your shingles where granules have worn away reduce the effectiveness of UV protection and water resistance. Over time, natural elements remove these granules in small or large quantities. Any sections of missing or reduced granules creates an opening for water / ice, collected debris, and other things that can accelerate the aging of your roof. You may first notice granules accumulating in the gutters, even in a relatively new roof. This is normal, but consider the granular loss over many years and how quickly that can be accelerated in areas prone to weather and wind impacts.
Moss or Algae
Dark streaks, green moss, or algae indicate moisture retention and can lead to long-term shingle damage. Moss growth will halt and trap water, leading to potential leaks.
A bit tougher to identify is an algae growth that can create dark stains that are sometimes overlooked or attributed to regular aging. As algae accumulates, the stains can darken and lengthen over time.
Wavy Roof
A sagging or wavy appearance often points to structural issues beneath the roofing materials and should be inspected immediately.
Rusted Gutters / Nails
Corroded flashing or gutters can lead to leaks in vulnerable roof areas, especially near chimneys, vents, and valleys. Moreover, nail heads popping through shingles or showing rust are signs of age, poor installation, or weather damage.
