Asphalt Roof Repair or Complete Roof Replacement? What to Look Out For.

If you notice that your residential or commercial asphalt roof is showing signs of damage, it can be difficult to know if you require a repair or a complete roof replacement. We always recommend hiring a trusted professional to assess any damage or minor issues, but knowing what to look for is the first step in determining whether it’s time to replace your roof.


Shingles should lie flat against the roof. If you find just a few shingles are damaged, cracked, or buckling, you definitely need them repaired. However, if you notice that your roof has bald spots where granules are missing, it may be time for a roof replacement. There are two ways your shingles can curl:

  • Cupping – happens when the edges of your shingle tab turn upwards. If you notice that your shingles are curling, don’t panic – this doesn’t necessarily mean you need a full roof replacement. A roofing professional will assess your roof to determine the extent of the curling and recommend whether you need a roof replacement or repair.
  • Clawing – happens when the edges of a shingle are flat and the middle starts to come up. Both cupping and clawing are due to weathering and can lead to leaks. If your roof has been properly installed and is less than 10-15 years old, it may just need repair.

Cracked shingles are often caused by wind damage. If you notice that just a few shingles are cracked, rest easy, no need to replace your entire roof! A reputable roofing specialist can easily replace individual shingles. If you see cracked shingles all over your roof, we recommend that you have your roof replaced.


Notice that a few shingles are missing? Don’t fret — a simple repair by a roofing expert can fix the issue. However, if your roof resembles a checkerboard, it’s probably time for a complete roof replacement.


Granules help protect your roof from the sun — once the granules fall off, the quality of your roof’s shingles will deteriorate fast. If your asphalt shingle roof is relatively new and you notice granules in the gutters, there is no need to panic – these are just extra ones left behind. If your roof is 10-15 years old, however, missing granules can lead to bigger problems, so this means you may need to replace your roof.


Moss can be a beautiful aesthetic for your yard, but you definitely don’t want to see it on your roof. Moss, mold, and fungi can indicate trapped moisture and can destroy your roof over time. Moss can get under your shingles and begin to lift them up, creating more problems (leaks!) If your roof is exposed to a lot of shade or moisture, double-check for signs of moss. Note that moss or algae don’t necessarily indicate a serious problem – if moss or algae hasn’t caused shingle damage, it can be lightly brushed off. Just make sure your roof doesn’t go unchecked – ensure you take a closer look or contact a professional roofer.


If your roof is sagging, this is a serious problem and may require replacing before further damage occurs. A professional roofer can take a closer look and check for any trapped moisture, rotting boards, or other sagging areas. If your roof isn’t properly maintained, it could begin to sag.


If you go up in your attic and see sunlight, or signs of water staining, this may be a telltale sign that you have holes or cracks in your roof. If light can get in, so can rain, cold air, and snow. You should definitely have this repaired asap. Call a pro. An expert will inspect your roof for extensive damage and assess whether your roof needs a repair or complete replacement.


Flashing is a crucial metal material installed on seams, ridges, and valleys of the roof, or anywhere in sections where parts of the roof meet such as around a chimney, skylight, vent, or dormer walls. Flashing directs water and moisture away from certain areas of your roof and is commonly available in steel, aluminum, and copper. Without it, your home or business is vulnerable to moisture and leaks. If flashing is faulty or damaged, it can create serious issues and expensive roof repairs. In fact, the leading cause of leaks in roofs is flashing failure.

Roof flashing is designed to be durable, but over time it can show signs of wear. It can be damaged by severe weather elements and should be expected annually. Here are some signs to look out for:

  • Small holes
  • Patches, bends, cracks, dents, or tears in the roof.
  • Asphalt shingles are curling, broken, or damaged.
  • Gutters are clogged, rusting, sagging or have leaky seams.
  • Rust or corrosion
  • Internal leaks
  • Crumbling or missing sealant.
  • Worn siding or shingles
  • Missing pieces
  • Torn flashing that buckles around the roof features.
  • Asphalt shingles are decaying, molding, or splitting.

If you are unsure whether or not to replace roof flashing, we always recommend consulting with a professional. A roofing expert will inspect the flashing thoroughly, and make a recommendation based on its condition and design life.


While many shingles today are manufactured for durability, other factors can come into play to accelerate the aging of your shingles. If your roof is not properly ventilated, for instance, this can reduce the lifespan of your shingles. If your roof is almost 20 years old, it’s probably time to look at replacing your roof entirely.


A trusted roofer can help diagnose a problem and determine what type of repairs your roof requires. Even if you don’t notice evidence of roof damage, an annual roof inspection is always recommended to catch any minor issues before they become big problems.
