Sometimes a roof can naturally reach the end of its useful life without experiencing a roof failure.  If replacing an old roof is delayed it could result in bigger problems down the road. Watch for the warning signs to be sure to give yourself plenty of time to add the project to your to-do list.

  1. Shingle edges are curled or shingle tabs are cupped.

  2. Bald spots where granules are missing.

  3. Cracked shingles.

  4. Your roof is at least 20 years old; while many shingles today are produced for durability, many factors can accelerate the aging of shingles. For example, if your roof is not properly ventilated, it can negatively impact your shingles.

  5. The roof just looks old and worn.

  6. Neighbors are getting new roofs. Homes built around the same time period can be experiencing the same types of weather conditions can mean that your roof is nearing its useful life.

  7. Dark streaks. Airborne algae cause dark streaks on roof decks. While this may not necessarily harm the roof shingles, it may not look good.

  8. Moss can grow on roof surfaces that don’t get much sunlight, especially in cool, moist climates. Moss growth can be more than a cosmetic issue. Moss holds moisture against the roof surface and over time in freezing climates can cause damage to the granules on the top of the shingles. Moss can be brushed off but it won’t prevent it from growing again; take care not to damage the shingle surface.

8 Potential Signs That Your Roof May Need To Be Replaced:

Asphalt Shingles

  • New styles can mimic shingles, shakes, slate, and tile, and dozens of colors are available

  • Metal is a 50 to 100-year roofing material with warranties of 30-50 years

  • Metal reflects solar radiant heat, so can keep your home cooler and control energy costs in hot weather — something that is a challenge with asphalt shingles

  • Many metal roofing profiles have a Class A fire rating

  • Some styles of metal such as corrugated and ribbed panels that are common to barn roofs can be installed quickly and on a budget

  • Metal sheds rain and snow better than most other roof materials, which helps prevent ice dams during extreme cold

  • Recycled materials are used in most metal roofs, and old metal panels are 100% recyclable at the end of their service life

  • Today’s metal roofing products are surprisingly lightweight yet offer outstanding resistance to impact

  • Metal roofs look great on wood-sided homes, cabins, cottages, and those with simple, rustic design

  • Many residential metal roofs such as metal shingles, standing seam, and stone-coated steel tiles are designed to meet the most-stringent building codes and wind uplift standards

  • Asphalt shingles offer good fire protection

  • Look good on most any style home

  • Shingles are often the most affordable roof covering option, especially in good/better ranges

  • The best asphalt shingles are a 30-year roof solution installed on homes located in moderate climates

  • The cheapest 3-tab shingles are an affordable way to dress up a home before putting on the market

  • Broad selection of colors and styles including affordable three-tab and architectural shingles that mimic shakes and slate

  • No support beyond standard roof sheathing is required for shingles

  • 3-tab shingles are rated for 60-70 MPH wind uplift, while standard architectural shingles are rated for 110 MPH winds; high-wind shingles are rated for 130 MPH

  • High-impact shingles such as the ones manufactured by GAF should be used for heavily wooded locations and areas where large hail is possible

  • Some shingle repairs are easy and cost-effective
