Like making the most critical decisions, deciding when to replace your roof is not easy. It requires a lot of thought and consultation. But why would anyone be concerned about when their roof needs a replacement?
A properly installed roof will last several decades. However, it will be constantly exposed to sunshine, rain, snow, wind, hail, and other factors. This exposure leads to gradual deterioration, and over time, your roof starts to come apart or become unreliable as it becomes less functional in terms of protection and aesthetics.
In this article, you will learn what to look out for to determine if your roof is due for a replacement or if what it needs is just a simple repair. You don’t necessarily need to be an expert to know that; that’s why you have us. So, back to the question: How often should you replace your roof?
What Is the Life Expectancy of a Roof?
Your roof’s lifespan is dependent on various factors, including the type of material, the quality of the material, maintenance, climate conditions, and the type of roof. Some types of roofing materials are more resistant to factors like weather, UV rays, pests, and other damaging factors than others.
However, roofs’ life expectancy is usually between 20 and 30 years. Again, this also depends on the quality of the materials used, workmanship, and maintenance culture.
How Can You Tell If a Roof Needs Replacement?
You can’t tell by simply looking at your roof from the ground that you should replace it. Hence, you have to critically examine your roof’s condition to look out for specific signs that indicate damage or a need for replacement. We listed some of the signs to look out for below:
Leaks and water damage
Leaks and water damage are usually among the most significant signs. Once you start observing leaks or water stains on your walls or ceilings, you know there is a big problem that needs fixing. It is the start of many other problems; hence, the need to act early.
Damaged or missing tiles
When inspecting your roof, look for curled, cracked, or missing tiles. Missing and damaged tiles make your roof system vulnerable to leaks and damage as they become exposed to water. In a case like this, the simple solution might be to replace the missing or damaged tiles.
Roof’s age
As we stated earlier in this guide, different types of roofs have their respective lifespans, the average being 25 years. So, one of the easiest ways to know if your roof needs replacement is to take note of the lifespan of your roofing material and do a countdown. Once it nears the end of its useful life, you should start mentally preparing for a replacement so you aren’t caught off guard.
Daylight seeping through your roofboards
The only source of sunlight should be your window, doors, or skylight/sun tunnel. Daylight seeping through your roof is abnormal and should be corrected. It implies that water can also get in and cause more damage.
Loss of granules
As roofs age, they tend to lose their granules. This action leads to an accumulation of residue in your roof’s drainage. This could be a sign for replacement because when roof tiles lose their granules, it may reduce their functionality.
Uneven or sagging roof
The sight of a sagging or uneven roof indicates structural damage and should be a reason for concern. You might actually need to replace your roof. If you ever find yourself in such a situation, contact a reliable roofing expert to perform a thorough assessment and provide the best solution.
Moss or algae growth
The presence of mold, algae, or moss is a sign of water damage. They weaken your roof structure and pose a risk to the health of your home’s occupants, so you shouldn’t ignore their presence.
Damaged flashing
It is best to ensure your roof flashing is always in good condition. Flashings are placed around roof penetrations like vents and chimneys to prevent leaks. So, a damaged flashing is definitely not good news, as it could cause leaks in your roof system.
Increase in energy costs
Poor insulation, typically a result of a deteriorating roof, may cause a sudden rise in energy costs. The hack to prevent such a situation is to assess your roof carefully before winter so that you can fix any problems or underlying issues.
The presence of at least one of these signs is an indication that you need to invite a roofing contractor to visit your home for a thorough assessment. They will give you more accurate feedback from a professional’s perspective and suggest the best solution: a roof replacement or repair.
How Often Should You Replace Your Roof?
Every homeowner dreams of having a long-lasting roof over their home. Therefore, you aren’t meant to replace your roof frequently. You should replace it only when it has reached the end of its lifespan or has suffered irreparable damage.
Provided that your roofing contractor correctly installs your roof and you maintain it properly, your roof will reach its estimated lifespan. Therefore, all things being equal, you have no business replacing your roof, at least for the next 20 years after installation, depending on the roofing material you use.
Life Expectancy of Roofs Based on the Type of Material
Choosing the best type of roof for your home is crucial for longevity. An excellent roof will protect your home and its contents against the elements. The better the quality, the lower your chances of replacing your roof. Below are some of the different types of roofing materials and their expected lifespans:
Metal Roof
Metal roofs are typically made of aluminum, steel, or copper. With the correct maintenance, they are expected to last for as long as 40 to 70 years. They are resistant to fire, pests, and rot and are ideal for commercial roofing projects.
Slate Tiles Roof
Every roofing expert would agree that slate roofs are undoubtedly one of the most durable materials. Want to hear a fun fact about this roof type? They usually outlast the structures they protect and beautify. Their other strengths include their resistance to pests and rot. They are also eco-friendly. However, only a few homeowners can afford them because of the high cost of materials and installation. They also require specialized skills for installation.
Asphalt Roof
Asphalt roofs come in three variants: architectural, 3-tab, and luxury. Each has a different lifespan. 3-tab asphalt shingle has the shortest life expectancy of 20 to 25 years. On the other hand, luxury and architectural asphalt shingles can last for as long as 25 to 30 years. However, luxury shingles can still last more than 30 years.
Clay Tile Roof
Clay tiles are popular for their longevity and unique appearance. They are so durable that they can last up to 100 years. When you install and maintain them properly, they can even last longer. They are highly resistant to pests, rot, and fire. However, the tiles tend to be brittle, and you may need to replace the affected tile on the roof whenever that misfortune happens.
Concrete Tile Roof
Concrete tiles are also durable and can last up to 30 to 50 years when given the proper care. They are affordable and come in various finishes and colors.
Composite Roof
Composite roofing shingles, also known as synthetic shingles, are made to imitate the look of traditional roofs. They are cheaper alternatives to materials like metal, slate, and wood. Depending on maintenance and the manufacturer, they are expected to last for as long as 10 to 20 years.
EPDM Roof
EPDM roofing is popular for low-slope or flat roofs. Although it has a life expectancy that falls between 20 and 30 years, it can last even longer when you inspect it regularly and give it proper care.
Conclusion
Once more, many factors, such as the type of roofing material, the quality of the installation, maintenance, and local climate conditions, affect the lifespan of your roof. Although there is no exact time for a roof replacement, having a good maintenance culture and being observant are vital.
Identifying problems and correcting them on time will contribute greatly to extending your roof’s lifespan. Therefore, never hesitate to involve a roofing expert whenever you notice any deterioration or structural damage to your roof. They will give you a definite answer to the question of when to replace or repair your roof.
