Your roof is like any other object. It has a lifespan, and that means that once age sets in things can go wrong with it. Most roofs have a maximum lifespan of 20 years, but others may not. Much of what can shorten your roof’s life has to do with location, weather conditions, and the age of your home.

If your roof isn’t properly sealed against the elements, you can face the possibility of needing to have it replaced. Other factors include improper ventilation and shingles that get worn over time. Wind damage, hail damage, and water damage can result in missing shingles that need to be replaced. Below are some of the main signs that tell you when it’s time to replace your roof.

1. Shingles That Are Curled or Cupped

If your roof has lived through many seasons, it can experience a lot of wear and tear. Shingles are constantly exposed to heat, cold, rain and snow at various points throughout the year. If you see your shingles in this condition, it is time to get your roof repaired or replaced. Your asphalt shingles may also have bald spots or missing granules, both of which are nothing more than wear and tear. But since this means weakened shingles, you should be aware that problems with your roof will follow. You may be able to get away with a simple repair or shingle replacement, but it will be time to get your roof replaced eventually.

2. Shingles That Are Cracked or Worn

Shingles that are cracked or worn have most likely suffered the impact of wear and tear. Sometimes, this can happen in cases where your home is old or your roof has not been properly ventilated. Getting your roof replaced becomes necessary in cases where multiple shingles get damaged or cracked over time. Chemicals inside of shingles can evaporate or dry up, which leads to the cracks and the bald spots associated with older, worn out shingles.

3. The Sudden and Unexplained Appearance of Dark Streaks

If you start to notice the sudden appearance of dark streaks, it may be due to airborne algae or the accumulation of mold and mildew. Older shingles that lack proper protection against algae can attract a type of algae known as Gloeocapsa magma, which is one of the most common issues concerning older shingles that are exposed to weather elements year after year. Thankfully,  your roofing contractor can assess the damage and determine if a roof replacement is necessary. 


A good roof has a maximum lifespan of twenty years. Even without any significant damage, two decades should warrant at least an inspection done by a professional roofing contractor. In either case, you can check us out online or give us a call today.
