How Long Does A Roof Last?
A roof is literally a home’s crowning piece. But despite the durability of modern roofing materials, your roof won’t last forever. Various factors like age, wear and tear, environmental elements, and maintenance cadence can all affect how long your roof lasts.
The responsibility of every homeowner is to carry out proper routine maintenance on their roof to extend its lifespan where possible. Ensuring the roof is in good shape, free from any damage, and maintains its integrity can keep the roof young and protect your investment.
But even with all your best efforts, it’s important to know your roof’s likely expiry date so you can prepare well in advance. In this article, we’ll discuss the factors that impact the longevity of your roof, the different types of roofing materials, and their life expectancy.
Factors that Impact the Longevity of Your Roof
Several factors contribute to determining the longevity of your roof, but most of a roof’s life expectancy is dependent on the material used. To be sure you’re making the right choice when it comes to acquiring a roof for your building, here are factors that can impact the longevity of your roof:
1. The Kind of Material Used
Although a roof’s cost and lifespan are often linked together, the kind of material used and its durability do significantly impact the roof’s longevity. Every roofing material has different durability, which shows how long it can last in various weather conditions.
2. The Quality of the Materials
Regardless of your choice of roofing material, whether for your home or business, each has its high and low-quality versions. The low-quality versions of roofing material are more likely to require constant repairs and have a shorter lifespan. This is why it is ideal to consider going with a better option. Contacting the service of a trustworthy contractor that employs high-quality materials will assist you in making the best option for your roof.
3. The Quality of Workmanship Installation
It is advisable to thoroughly research roofing contractors’ qualifications, insurance, liability coverage, and the customer’s rating before contacting them for your job. Choosing the right qualified contractor can have a more significant impact on the longevity of your roof.
4. The Weather Effect
The temperature and the amount of sunlight that your roof receives significantly impact its longevity. The high and inconsistent temperatures, as well as extreme storms that can cause roof damage, put your roof’s health at risk, so it’s critical to use long-lasting materials.
Different Types of Roof And Their Life Expectancy
Here are the different types of roofs and their life expectancy you can choose from.
1. Metal Roof
Depending on the metal type and design, metals usually last between 40 to 70 years with warranties from 20 years to a lifetime. Metal roofs made from copper and zinc can last for 100 years. The three different types of roofing metals and their duration include:
- Stone-coated steel tiles: These metals are quite popular in places with hurricanes. Their lifespan is from 30 to 50 years, and they can sustain a gusts speed of 155 miles per hour.
- Stand seam metal roofing: This is a famous residential metal roof that can last up to 50 years and sustain a gust speed of 100 miles per hour.
- Ribbed metal panel: They are cheaper to set up than seam roofing, and their duration is between 25 and 50 years.
2. Asphalt Shingles
Aside from its popularity in the U.S, Asphalt shingles are quite inexpensive, last longer, and have a warranty of 25 years. Asphalt shingles, which are made of fiberglass and asphalt sealant, can effectively protect your roof structure from snow, wind, rain, and UV radiation.
Asphalt shingle roofs typically last 15 to 30 years. This, however, can vary depending on your location’s climate and weather circumstances. There are three types of an asphalt shingle roof, and their duration is as follows:
- Three-tab Asphalt Shingles: They happen to be the cheapest and also a Do It Yourself roofing. They can last up to 15 – 20 years.
- Architectural Shingles: They do not appear to be of a higher price tag and can last from 20 to 30 years.
- Composite Shingles: They have a higher price tag and can last 25 to 40 years.
An Asphalt shingle that has lasted between 15 to 20 years or experienced storm damage should be considered for inspection or replacement.
3. Wood Shake and Shingles
A wooden shingle roof typically lasts about 30 years and comes with a 30-year warranty. However, for wood shake and shingle roofs to stand the test of time, they must be maintained regularly. Cleanings and repainting or staining of wooden ceilings are required every year, and repainting or staining every five years.
The sort of wood you use will also have an impact on the longevity of the roof. Because cedar is rot and pest resistant, cedar shakes, for example, survive longer than other types of timber shingles.
4. Slate Tile Roof
Slate roofs are durable and can last anywhere from 75 to 200 years. This makes them one of the most durable roofing materials available. Manufacturers of slate tiles provide warranties ranging from 50 years to a lifetime. Extreme weather conditions, such as severe winds or temperature changes, are no match for slate.
Slate requires less maintenance because it doesn’t hold much moisture. Note that slate is a very heavy material, weighing roughly 1,000 pounds per 100 square feet. It would be best to get your roofing system evaluated before constructing a slate roof to ensure that it can sustain the weight.
How Long Can a Roof Stay Before It Can Be Replaced?
Knowing the various life expectancy of the various roofs is not a full guarantee that you shouldn’t check on them to see how they’re fairing, at least. A thorough check on your roof to determine if it will be replaced is highly recommended. Some obvious warning signals that your roof needs a replacement include:
- Ceiling discoloration
- Roof material deterioration
- Leakage and water damage
- Pest making their way inside
- Visible roof and external damage
Pay attention to the condition of your roof if it has held up well over time and is near the very end of its lifespan. Saving up, prepping ahead of time, and talking to a roofing specialist about replacement options are good ways to start. This way, when the time comes to replace your roof, you’ll be prepared and able to decide on the sort of roof you want and the quality of materials you’ll need for adequate protection.
