Weather is a major factor in the lifespan of asphalt roofing. The continuous change of temperature, precipitation, and humidity damage the roof during its lifetime. Homeowners and property owners need to be aware of these potential risks, and what steps can be taken to protect the roof from the worst weather. In this article, we’ll explore how weather affects the lifespan of asphalt roofing, precautions one can take to mitigate the damage, and make sure that the roof performs optimally.
What is Asphalt Roofing?
Asphalt roofing is a popular roofing choice for many residential roofing styles. It’s a composite material made up of layers of asphalt and fiberglass sheets and reinforced with mineral granules. Asphalt roofing is a great choice for homeowners and property owners looking for a durable, quality roofing product that can handle a variety of weather conditions.
Weather is one of the most important factors that impact the lifespan of asphalt roofing. The sun’s UV rays, the rain and snow, wind and temperatures can all cause damage to asphalt roofing. Here’s a look at how different types of weather can affect asphalt roofing:
UV Rays From the Sun
UV rays from the sun can cause the asphalt layers to oxidize, causing the protective granules to loosen or fall off. This exposes the underlying layers to more sun exposure, which can cause further deterioration.
Rain and Snow
Rain and snow can also cause asphalt roofing to deteriorate prematurely. Rain and snow can cause water to pool up on the roof and lead to moisture build up over time, which can lead to rotting of the roof material. Additionally, excessive snowfall during the colder months can cause stress on the roof, leading to sagging and cracking.
Strong winds can also cause damage to asphalt roofing by knocking off the roofing’s protective granules. Loose granules can cause gaps in the roof, making it easier for water to seep through and increase the chances of water damage. Wind can also cause the roof to become lifting in some areas, which can cause further issues in the long run.
Excessive fluctuation in temperature can cause asphalt roofing to become brittle, leading to cracks forming in the roof. When cold weather, followed by hot weather happens in quick succession, this can cause the roofing material to expand and contract, leading to further damage and decreased roof performance.
Precautions One Can Take
There are steps that homeowners and property owners can take to minimize the damage caused by weather to asphalt roofing, and maximize the roof’s lifespan.
Regular Roof Maintenance
Regularly inspecting, cleaning and maintaining the roof will help keep it in peak condition and handle extreme weather better. Homeowners and property owners should have their roofs inspected at least once a year for any potential damage, and then have it repaired if there are any issues.
Quality Roofing Materials
Using only quality roofing materials is also important to ensure the longevity of the roof. Homeowners and property owners should always shop around to make sure they’re using the best materials, and they should also be sure to hire only qualified and experienced roofing contractors to ensure the proper installation of the asphalt roofing materials.
Fitting Protective Materials
Roofing materials such as shading, overhangs and awnings can be fitted to the roof to provide some protection from the sun and other elements. Additionally, using energy-efficient materials like coatings, reflective paints and membranes can help protect the roof from UV rays as well.
Installing Ventilation Systems
Having an adequate ventilation system installed can help reduce the temperature of the roof and keep it cooler during the hot season. This will help reduce the stress on the roof and keep it in peak condition for longer.
People Also Ask
What is the average life of an asphalt roof?
The average life of an asphalt roof depends on the quality of the installation and the materials used, but typically they last between 20-25 years.
How long does an asphalt roof last?
Asphalt roofs can last around 20-25 years, depending on the quality of the installation and materials used.
Can weather shorten the life of asphalt roof?
Yes, extreme weather like UV rays, rain and snow, wind, and fluctuating temperatures can shorten the life of an asphalt roof. Regular roof maintenance, quality roofing materials, and the installation of protective materials and ventilation systems can help protect the roof from weather damage and extend its lifespan.
What type of weather is best for asphalt roofing?
The best type of weather for asphalt roofing is moderate temperatures throughout the year with minimal precipitation. This will help keep the roof cooler, which will reduce wear and tear from UV rays and fluctuations in temperature.
What should one look for before getting an asphalt roof?
Before getting an asphalt roof, homeowners and property owners should look for quality roofing materials and a skilled, experienced roofing contractor to ensure the proper installation of the asphalt roofing materials. Additionally, one should look into getting protective materials such as shading, overhangs, awnings, and energy-efficient materials like coatings, reflective paints and membranes to protect the roof from weather damage.
Weather plays a major role in the lifespan of asphalt roofing. Regular roof maintenance, quality roofing materials, and the installation of protective materials and ventilation systems can help protect the roof from weather damage and extend its lifespan. Understanding how different types of weather can affect asphalt roofing, as well as the steps one can take to protect it, is key to making sure that the roof performs optimally.
