When Is the Best Time of Year to Replace Your Roof? What Experts Say

Owning a home comes with a seemingly endless litany of maintenance and repair tasks. For example, you may have noticed that your roof is getting up there in age, and you need to repair it more often. This begs the question—should you just replace the roof entirely and start from scratch?

Here, we spoke with construction and roofing professionals about how long different roofing materials last, the signs that your roof needs to be replaced, and the best time of year to do it.

Types of Roofs

There are many different types of roofs—some will last longer than others. 

Asphalt Shingles

Asphalt shingles are the most common type of roofing in the United States due to their cost effectiveness and longevity.

“They typically last 20 to 30 years depending on installation quality, ventilation, and climate,” says Aleks Krylov, founder and president of Stern Roofing. Asphalt shingles are also relatively easy to repair since you can replace single shingles at a time.

Metal Roofing

Metal roofs are particularly durable against a range of weather issues like hail, high winds, blizzards, harsh heat, and even fire, making them suitable for all types of climates.

They’re also energy-efficient because they reflect radiant heat, rather than absorbing it. They last a long time—40 to 70 years, according to Krylov. However, metal roofs tend to have higher upfront costs. 

Cedar Shake

Cedar shake brings a natural, rustic look to your home’s exterior and is generally long-lasting, depending on your climate. For example, humidity can cause faster deterioration, according to Krylov. With proper maintenance and the right conditions, cedar shake roofs can last between 20 and 40 years.

Clay or Concrete Tiles

Clay or concrete tile roofs provide lasting durability and longevity and are popular in warmer climates. When properly installed, they can last well over 50 years—clay tiles in particular can last about 100 years.

“They’re dense, durable materials that don’t degrade the way petroleum-based shingles can,” says Albert Bou Fadel, a construction expert and CEO of SmartBarrel.

Slate

Slate is a metamorphic rock, meaning it can stand up to hail, fire, and lashing winds. A roof made with this material can last 50 years or more. However: “They require structural support and a higher upfront investment,” says Krylov.

Signs Your Roof Needs to Be Replaced

There are a few signs that your roof is in need of repair or replacement. 

Shingle Damage

“Check your roof regularly to see if shingles are curled, cracked, or otherwise damaged or missing, especially after storms,” says Craig Ricks Jr., president of Acadian Windows and Siding. “These are the most obvious signs that your roof needs repairs, if not replacement.” 

Asphalt Granules

Take a look at your gutters for any granules from asphalt shingles, which can mean that they're starting to degrade. 

Leaks and Water Stains

If you’re noticing water stains on the ceiling or can see sunlight poking through the attic, then there’s likely more damage than you realize at play.

“In many cases, homeowners don’t notice deterioration until water intrusion occurs—by that point, replacement is often more cost effective than repair,” says Krylov.

Rotted Roof Decking

Krylov recommends checking for rotted roof decking. Discoloration, sagging areas, cracking or crumbling, or musty odor can all signal rotting. This is likely caused by water or moisture coming through the roof’s shingles.

“We also advise homeowners to check the condition of flashing around chimneys and roof penetrations,” he says.

The Best Time of Year to Replace It

The best time of year to replace a roof is spring or fall. These seasons bring moderate temperatures and drier conditions, which are ideal for proper installation. “Very hot weather can make shingles too soft, while freezing conditions prevent proper sealing," says Fadel.

However, consider your individual climate when scheduling a roofing install. “If you live in the Gulf South like me, where hurricanes are a factor, then spring is the better option. You can make sure your roof is fully installed, inspected, and settled before any storms start rolling in,” says Ricks. 

Ultimately, the best time to replace a roof is before it fails and you’re at risk of more damage. “If a roof is compromised, waiting for a perfect season can lead to interior damage that far exceeds the cost of timely replacement,” says Krylov.
