In general, roofs can last between 20 and 100 years, depending on the materials used, the quality of the workmanship and the climate. An asphalt shingle roof can last between 15 and 25 years, if properly maintained and saved from any major weather event or disaster. If properly ventilated and installed correctly, it should take advantage of 80 to 85% of the lifespan of an asphalt roof. That means you can expect to get between 20 and 22 years of your 3-tab tile roof and 25 to 28 years of your dimensional shingles.
Even when a shingle is called a 30-year-old shingle, that doesn't mean it's going to withstand the weather and damage for a full 30 years. That doesn't mean you have a 30-year warranty either. What this means, and the same goes for 40- and 50-year-old shingles, is that the life expectancy of these shingles is about 30 years when placed under ideal conditions, such as minimal exposure to the sun, shade, small temperature fluctuations, no wind damage, etc. In reality, no condition is truly ideal for any type of shingles, regardless of whether they are lifelong or 3-eyelash.
When you choose a roofing company or contractor to replace your roof or install one in a new home, understand that choosing several types of shingles, shingles, metal, or any other roofing material is just one aspect of manufacturing a roof with an extended lifespan. Another reason to consider replacing your roof is the value it adds to your home if you plan to sell it in the near future and your roof is between 15 and 20 years old, depending on the type of material used, the quality of the construction and any damage that may have occurred. In some places, tin roofs are preferred because of their ability to withstand most weather events and can last as long as most metal roofing systems, although they lack the longevity of copper and zinc roofing. You or your roofing company should check your roof regularly, especially if you think it's time to buy a new roof or if you think the newer roof might be defective.
You'll also want to consider other factors before replacing your roof or buying a property: the age of the roof, the number of layers of shingles there are, and whether the roof is properly reinforced and ventilated. If you're looking for a new roof, you might also hear that roofing companies or contractors describe certain types of roofs as “30-year roofs” or maybe even “50-year ceilings” or other periods of time. That said, there are several different types of asphalt shingles, as well as other roofing materials to consider when estimating the longevity of a particular roofing system. If you're looking to buy a property with an older roof (or your own roof hasn't been replaced in some time), you may even see 50-year-old shingles or roofing systems on the market, and while you should always have a roof inspection done before buying a new house or building, it's possible that some types of roofs so that They last so long.
An important thing to consider when choosing a roofing system or buying a new property is the roof's resistance to wind lift, which is the suction effect created by wind forces when air flows parallel to the roof surface. If you've experienced a major weather event or catastrophic disaster, such as a hurricane, tornado, house fire, or smoke damage, you already know that you need to replace your roof and that it's time to work with your insurance company to file a roof insurance claim and do the necessary work. Like PVC, TPO roofs are energy efficient and can last longer than an EPDM rubber roof (the most popular single-layer roofing membrane on the market). One thing to keep in mind is that slate roofs are quite heavy compared to alternatives, so the underlying structure must be properly constructed to support their weight; if you are replacing a different type of roof with slate shingles, you may need to improve or build the reinforcements and beams to support The blackboard.
There are a variety of online guides for doing roof repairs, so if you're comfortable with DIY, you can often fix or apply new shingles to your roof on your own. A hailstorm, a snowstorm, a tornado, or other catastrophic weather event can also shorten the life of your roof and you may need a complete replacement or roof repair. It doesn't matter if you need repairs or a complete roof replacement, your contractor plays a huge role in the life of your asphalt roof. If the roof feels spongy or if you start to feel like you bounce a little when you walk on it, it may need to be replaced.
