What is the Average Life of a Roof?
What Is the Average Lifespan of a Roof? Maintaining the condition of a house roof is one of the primary duties for homeowners to fulfil, as a roof serves to protect its structure against water damage and mould growth, while also adding aesthetic value by adding curb appeal if it has been professionally replaced.
A roof’s average lifespan can depend on many factors such as its material, quality and thickness of roofing materials as well as maintenance history; asphalt shingles typically last between 20 and 25 years while metal roofs can last 70 or more.
What Is the Average Life Expectancy of a Flat Roof? Membranes typically constructed of felt combined with asphalt and covered by gravel tend to last about 10 years before needing replacing, though synthetic products like rubber roofing might last longer due to being without gravel layers.
What Is the Life Expectancy of an Aluminium Roof? An aluminium roof may last for as long as 70 years depending on its quality and thickness – however low quality metals (26 to 29 gauge) with thinner gauge will only last 20-25 years before needing replacing.
What Is the Average Life Expectancy of Composite Shingles? Composite shingles (or tiles), are made of fibreglass and asphalt composite materials and mimic the look of slate and cedar roofing material. Their cost is lower than standing seam panels while they can withstand up to 110 MPH wind uplift. These composite roofs can be installed by a DIY homeowner, but professional installation is recommended.
How Long Does an Asphalt Shingle Last?
The average lifespan of an asphalt shingle is 15 to 18 years, though it can last longer or shorter based on the weather conditions and how well it is maintained. Damaged or missing granules, major cracks, or curled shingles are a sign that your roof needs repair or replacement. If your shingles are leaking, you may need to replace them with new ones.
Architectural shingles, on the other hand, are 50% thicker than 3-tab shingles and can last 30 years with proper maintenance. They are also known as dimensional shingles and come in a variety of colours and designs. In addition to providing better protection, they are often recommended for homeowners who have an older house because they help disguise any minor imperfections that might otherwise stand out.
One of the main differences between a standard three-tab shingle and an architectural shingle is that architectural shingles have a heavier mat base and multiple layers. Roofing contractors like this because the finished product weighs about 100-lbs.
The average life of a roof can vary from 20 years to 30 years, depending on the type of material used, the installation process, and other factors. The lifespan of a roof can also decrease significantly after a natural disaster or other event such as a tornado, hurricane, or house fire.
Asphalt shingles are the most common residential roofing material in the United States and have an average life expectancy of 15 to 20 years. Shingles come in a variety of styles, colours, and materials and can be manufactured from either glass fibre or organic composites.
What Determines the Lifespan of a Roof?
The life of a roof depends on a number of different factors. These include where the roof is located, its orientation and slope, and other environmental conditions such as tree branches that rub on the roof. However, there are some factors that can help you to predict how long your roof will last, even when it’s been installed incorrectly or neglected.
Temperature: Where you live and the climate in your area will have a significant impact on how long your roof lasts. Harsher climates, with more intense temperature swings and extreme winters and summers, tend to have shorter roofing lifespans. So, if you need a commercial roofer, we are here to help you.
Waterproofing: A quality waterproofing system should keep your home free from water leaks and ponding on your roof. The watertight membrane should also be made of a durable material that is resistant to UV damage.
Weather: Your region and local weather can have a huge effect on the lifespan of your roof. The heavier the rain, hail, snow and ice, the lower its lifespan will be. You should regularly inspect your roof for any signs of moisture or mould growth and repair problems as soon as you notice them.
The materials used to cover your roof also determine its lifespan. If the roofing material is not of a high quality, it won’t last very long and will need to be replaced sooner than if it was made of a higher-quality material.
