Signs It's Time to Replace Your Asphalt Shingle Roof

Signs It's Time to Replace Your Asphalt Shingle Roof

“Signs it’s time to replace your asphalt shingle roof” is a common discussion homeowners have with roofers and we thought it would be a valuable topic on our blog. 

You might not always pay attention to your roof, but it's one of the most important parts of your home. 

If you're unsure whether you need a roof replacement, here are some telltale signs to watch out for.

1. Missing Granules, Bald Spots

Asphalt shingles have granules that protect them from the elements, especially sunlight.

Over time, these granules wear off due to weathering and age.

One day, you might notice bald spots where the granules used to be.

A good example is when you're cleaning your gutters and find a lot of shingle granules.

This is a clear indication that your shingles have seen better days.

If the bald spots are widespread, it's time to consider a roof replacement.

2. Curling, Cracked Shingles

Curling and cracking are common signs of aging in asphalt shingles.

As shingles lose their granules, they become more vulnerable to heat and sunlight.

This can cause them to curl at the edges or crack.

Imagine walking around your neighborhood and noticing that your neighbor's roof has curled shingles.

You might think to yourself, "Well, it's only a matter of time before my roof starts looking like that."

And you'd be right.

When you see these signs on your roof, it's time to start planning for a replacement.

3. Lots of Moss

Moss may look charming on a quaint cottage, but it's not something you want on your asphalt shingle roof.

Moss retains moisture and can cause your shingles to deteriorate faster.

Picture this: you're driving down your street, and you see a house with a green roof.

You might think it's a unique design choice, but the homeowner might be dealing with a moss problem.

If your roof looks like a lush garden, it's time to call a professional roofer to assess the damage.

4. Shingles Blown Off the Roof

Strong winds and storms can cause shingles to blow off your roof.

While it's normal for a few shingles to go missing during a particularly nasty storm, if it's happening frequently, it's a sign of a bigger problem.

Imagine sitting in your living room during a storm and hearing a loud bang on the roof.

You go outside to investigate and find a shingle in your yard.

This might be a sign that your shingles are not properly secured, and your roof may need replacement.

5. Age of Roof: At Least 20 years Old

Asphalt shingle roofs typically have a lifespan of 20 to 30 years.

If your roof is approaching the 20-year mark, it's time to start thinking about a replacement.

Think about when you bought your home.

If it's been 20 years or more and you haven't replaced the roof, you're likely overdue.

Even if it still looks good, hidden damage can cause problems down the road.

6. Neighbors are Getting New Roofs

If you live in a neighborhood with similarly aged homes, you might notice your neighbors replacing their roofs.

This is a good indication that your roof may also be due for a replacement.

Imagine attending a neighborhood barbecue and hearing your neighbors discussing their recent roof replacements.

If everyone else is doing it, chances are it's time for you to replace your roof as well.

7. Flashing Cracked or Worn Down

Flashing is a crucial component of your roof that prevents water from seeping into your home. It's usually made of metal and is installed around roof penetrations like chimneys, vents, and skylights.

Over time, flashing can crack or become worn, compromising its ability to protect your home.

Picture this: you're in your attic during a rainstorm and notice water dripping near your chimney.

Upon closer inspection, you realize that the flashing is cracked.

This is a sign that your roof needs attention and possibly a replacement.

8. Rotting Boards Causing Sagging & Drooping

The structural integrity of your roof is essential for the safety and well-being of your home.

Rotting boards and damaged rafters can lead to sagging and drooping, which can cause further damage.

Imagine walking around your home and noticing a dip in your roofline.

This could be a sign of rotting boards and compromised structural integrity.

If you see these signs, it's time to call a roofing professional for a thorough inspection and possibly a roof replacement.

9. Leaky Roof & Water Pooling

A leaky roof is a clear sign that something is wrong.

Water pooling on your roof can cause damage to your shingles and the underlying structure.

Consider this scenario: you're in your bedroom during a rainstorm and feel a drip of water on your head.

You look up and see a small water stain on your ceiling.

This is a sign that your roof is leaking, and it's time to call a professional to assess the damage and determine if a roof replacement is necessary.

10. Storm Damage

Severe storms can cause significant damage to your asphalt shingle roof.

Hail, strong winds, and heavy rain can all take their toll on your roof, leaving it in need of repair or replacement.

Imagine waking up the morning after a powerful storm and seeing debris from your roof scattered across your yard.

This is a clear indication that your roof has sustained damage and may need to be replaced.

In conclusion, it's essential to keep an eye on your asphalt shingle roof for signs of wear and damage.

From missing granules and cracked shingles to leaky roofs and storm damage, these are all signs that it's time for a replacement.

Regular inspections and maintenance can help extend the life of your roof, but eventually, every roof will need to be replaced.

If you notice any of these signs, it's time to call a professional to assess your roof and recommend the best course of action.
