Depending on the quality of the material and the temperature where you live, you may expect a roof’s shingles to last anywhere from 20 to 30 years. Roof shingles’ lifespan is influenced by factors including the type of shingle, the manner of installation, and whether or not you maintain your roof.
In this section, we’ll look at the typical lifespan of various shingle kinds, along with the most common causes of roof deterioration, and how to tell if it’s time for a new roof. Slate roof shingles should endure at least 30 years, according to industry standards. The lifespan of a given material or shingle type varies.
Asphalt roof shingles are the most prevalent form of shingle, with a lifespan of 15 to 25 years. It is usual for 3 tab asphalt roof shingles to last 10 to 20 years. Extreme weather may damage them, but they can tolerate strong winds and heavy rain in temperate climes.
High winds necessitate architectural or premium asphalt shingles. Depending on the brand and the installation, they can last anywhere from 20 to 30 years. To ensure that your roof is protected for the long term, premium shingles have longer warranties. Both cedar shakes and composite shingles can last for 30 years or more with adequate care and upkeep provided they are properly maintained.
Roof Shingle Wear: Causes and Indicators
A person with shingles has no one else to confide in outside of the medical community. The purpose of roof shingles is to protect you from the elements, but exposure to the environment wears them down over time. A few of the most prevalent causes of shingle wear and how to recognize them are listed below.
Roof Shingle Heating and Cooling
As with road asphalt, the asphalt on your roof expands and contracts as the temperature changes. Asphalt shingles can break and curl if they are subjected to repeated heating and cooling cycles.
Shingles, despite being engineered to endure seasonal temperature changes, may eventually disintegrate if left outside in the weather. Exposure to the sun can also degrade the asphalt binder, making your roof appear older and reducing its ability to withstand wind and rain.
Weathering of the Shingles on the Roof
Weather damage can also be caused by rain and humidity if you reside in a humid environment. It is possible for water to seep beneath and through the protective layers of shingles that are more than five years old. If you live in a location that sees a lot of snowfall, asphalt might break.
Shingles can be damaged by the wind as well. While gusts of wind can shift or remove lower- or medium-quality materials, high-quality shingles are reinforced to withstand storms. Other storm damage, such as hail or fallen tree limbs, can cause shingles to snap or fracture.
Roof Shingles Are Getting Old
Roof shingles lose their ability to defend your home from the elements over time. All roofing materials will need to be replaced at some point in time. Your roof should be replaced if it is more than 20 years old.
