How long does a 30 year roof really last in Raleigh, NC?
A roof will last until it begins to break down, shingles curl or it leaks. To give the quickest answer possible, a 30 year roof will in theory last 30 years. There are several factors however that make a roof last longer or shorter which is what we will discuss in this article. Some of the variables include shingle quality, climate of the home, installation according to manufacture guidelines etc.
Like talked about previously the answer to the question “how long will a 30 year roof really last?” will vary on many aspects. For the purpose of this article we will assume that the 30 year roof is made of asphalt shingles. The common grade asphalt shingles will last between 15-20 years while the premium architectural shingles last between 25-32 years. Most common grad shingles however do not boast a 30 year lifetime expectancy. The lifetime expectancy of shingles can be shortened due to things such as extreme wind, moisture, climate, damages etc.
To give an example; a 30 year asphalt in Colorado will only last 27 years due to the large influxes in temperature and the heavy amount of snow on the roof. During the summer months the shingles endure 100+ degree temperatures and in the winter time have to survive through below freezing temperatures for several months. The type of climate makes the shingles more brittle over time which in turn makes them break down faster compared to a mild climate such as Texas where the temperatures do not fluctuate as much.
Manufacturing companies of asphalt shingles understand what a roof goes through in a 30 years period and have placed these lifetime expectancy timeframes accordingly. A roof lasting for 30 years however does not mean that you will never have to do maintenance or small repairs when a leak does happen. Generally speaking you should have a roof inspection at your own property every few years to see how the shingles are aging and if there are any areas that need maintenance or repairs.
Like mentioned in the above information, economy asphalt shingles (cheapest shingles) can degrade by 25% or more over a 15 year period. This means that the cheapest economy shingle could last up to 25 years but also may only last 15 years depending on how wear and damage they experience. Premium shingles which are called the “architectural shingles” are much more durable and will last 30 years and oftentimes even longer if properly maintained.
Roof maintenance can be things such as clearing off leaves each fall, making sure moisture can run off the roof properly and repairing any small leaks when they happen. Roof maintenance will play a large factor in how long your shingles last. The main reason why maintenance is so important is it allows water to drain from the shingles properly without getting trapped by these objects which can cause water leaks over time.
