Roofing Tips, Tricks and Ideas

How Old Should a Roof Be Before Replacing?

Published by Pickard Roofing at

As a homeowner, one of the most important decisions you'll have to make is when to replace your roof. There's no simple answer, as the age at which you should replace your roof depends on a variety of factors. However, by understanding common roofing problems and their causes, you can make an informed decision about when it's time for a new roof. So, how old should your roof be before replacing it?

What to consider when deciding whether to replace your roof

The type of roof you have:

The lifespan of your roof will depend on the material it's made of. For example, composition shingles can last up to 50 years, while asphalt shingles can last 15-30 years. Wood shingles have a lifespan of 30 years.

The climate you live in:

Climate can also play a role in how long your roof will last. For example, if you live in an area with high winds, your roof may not last as long as it would in a calmer location.

The amount of sun your roof gets:

Too much sun can cause your roof to deteriorate faster than it would otherwise.

The slope of your roof:

A steeper roof is more likely to last longer than a flatter one, as the water will run off more easily.

The ventilation in your attic:

Proper ventilation helps to extend the life of your roof by preventing moisture buildup.

The quality of the materials used:

Cheaper materials will obviously not last as long as more expensive, higher-quality ones.

The quality of the installation:

Even the best materials won't last as long if they're not installed properly.

The signs that it might be time for a new roof

You can see daylight through your roof boards:

If you can see daylight coming through the boards of your roof, it's definitely time to replace it.

Your shingles are curling or buckling:

Curling or buckling shingles are a sign that your roof is reaching the end of its lifespan.

Your roof is sagging:

A sagging roof is a serious problem and should be addressed as soon as possible.

You have missing shingles:

Missing shingles can leave your roof vulnerable to leaks and other damage.

Your roof is over 20 years old:

Even if your roof doesn't show any signs of wear, if it's over 20 years old, it's probably time to start thinking about replacing it.

How to choose the right roofing contractor

Get multiple estimates:

When you're ready to start looking for a roofing contractor, be sure to get multiple estimates. This will help you ensure that you're getting a fair price.

Check references:

Once you've narrowed down your options, be sure to check references. This will help you make sure that you're hiring a qualified and reputable contractor.

Get everything in writing:

Before work begins, be sure to get everything in writing. This will protect you in the event that something goes wrong.

Factors that can affect the price of a new roof

The size of your roof:

The size of your roof is one of the biggest factors that will affect the price of a new one.

The pitch of your roof:

The pitch, or steepness, of your roof can also affect the price. A steeper roof will be more expensive to replace than a flatter one.

The materials you choose:

As with the initial installation, the materials you choose for your new roof will also affect the price.

The complexity of the job:

If your roof is especially complex, it will likely be more expensive to replace than a simpler one.

Your location:

The cost of labor and materials will vary depending on your location.

The time of year:

Replacing your roof is typically more expensive in the summer than in the winter, as roofing contractors are in higher demand.
