What Factors Impact How Long Your Roof Lasts

  • Quality of the installation workmanship – A poor quality installation will shorten your roofs lifespan.
  • Environmental conditions – Exposure to high winds, extreme temperatures, and falling debris can decrease how long your roof lasts.
  • The quality of materials used – Cheaper materials wont cost as much upfront but will have to be replaced more often than other expensive roofing materials.
  • The type of roofing material used – Each roofing material has different durability, making them last longer or shorter in different conditions.

While there are several factors that impact how long your roof lasts, your roof’s lifespan most heavily depends on the materials used. Let’s take a closer look at the various roof types and how long each of them lasts.

The Best Way To Clean Your Shingles

This fungus is called gloeocapsa magma. Itâs a simple fungus that grows on the back side of a tree. It also grows on your roof and attaches to the shingle. It lives on what little oil is in the asphalt and it also really thrives on the crushed limestone, which creates all of the dark streaking on your roof.

One of the reasons people think they need to replace the roof is because they see this dark streaking and assume that itâs dirt or asphalt bleeding through. Most people donât realize that this fungus attaches to the roof and causes damage over time. And by the time they do realize, itâs too late.

Gloeocapsa magma can be removed safely with some environmentally friendly products that are out there. Most products contain bleach, which is not environmentally friendly and will damage the roof. Many roofing contractors also attempt to remove the fungus with a pressure washer. They set a high pressure hose and to a low setting and force the fungus to detach. However, that pressure causes additional damage to the roof. You donât want to use any type of pressure on your roofing shingle.

It can be challenging for homeowners to gauge when they should replace their shingle roof, and its not always as straightforward as missing shingles or ceiling leaks.

One key factor in helping you determine if you need a new roof is its age. Your roofs actual lifespan depends on several things, including the environment, the type of roofing materials used, and the availability of proper repair and maintenance.

In this article, we will discuss how long a 30-year roof really lasts and what affects its lifespan.

Roof Maintenance Pro Tips

Use these tips from the professionals to keep your roof in good shape for longer.

A pro tip for making your roof last longer is to be sure and cut all limbs from surrounding trees that are physically touching your roof, says Rick Abbiati, owner of Colony Property Investments. Even the smallest limb touching your roof can rub a hole right through the shingles and thus cause a water leak. With every gust of wind that branch is working its way through the shingles. Extend the life of your roof by keeping all fauna cut back.

The most common thing that grows on tile roofs is algae, says Mark Soto, professional roofer with Roofing MKE. You will want to continuously clean this from roofs with a combination of water and bleach. While some people use pressure washers, this is not recommended since it can actually damage the tiles. Cleaning them with your solution and then watering it down with a hose is the best way to go about it. Since tiles arent great at dealing with people walking on them, try to do it from the edge while on a ladder.

Independently of your region and roof type, you should also regularly clean gutters and ventilation to prevent clogging.

Theres No Such Things As An Algae

Thereâs more algae on roofs today because manufacturers use crushed limestone within the shingle as a filler so they donât have to use as much asphalt. Since asphalt is an expensive, petroleum based product, they try to minimize it by using more crushed limestone.

This then creates another issue. Manufacturers today are selling shingles that are called fungus resistant and algae resistant. But this really only holds up within the first two yearsâitâs completely prorated out within a two-year period. And itâs misleading to the homeowner because, by the second year, thereâs nothing left on the warranty. Of course, this is right around the time when youâll start to see fungus.

There are, however, simple solutions to solve the fungus problem, which leads to the third issueâ¦

How Long Does a Roof REALLY Last? (Roof Lifespan)

If you are in the process of buying a new home, you probably want to know the age of the roof and how much longer it will last. Similarly, if youve lived in your home for a while, you are probably also wondering about the current condition of the roof and whether its time to consider some viable replacement options.

This guide outlines the expected lifespans of most popular roofing systems for homes. Print it out and use it to assess the life expectancy of any roof when buying a new home or planning for future roof replacement needs in your own home.

Right Off the Bat: A typical asphalt shingle roof will normally last anywhere from 15 to 25 years before requiring a replacement.

    What To Consider When You Are Replacing A Roof

    One important thing to consider when you are choosing a roofing system or purchasing a new property is the resistance of the roof to wind uplift, which is the suction effect created by wind forces as the air flows parallel to the surface of the roof.

    When a gust of wind hits the side of a house or other building, some of that air moves upwards across the roof, creating a pressure differential that can blow off or damage shingles or tiles, or even entire sections of the roof altogether.

    Roofing systems are rated based on the amount of wind uplift they can withstand measured in miles per hour.

    If you live in a particularly windy area or one that is prone to tornadoes or hurricanes, youll want to ensure that you go for a higher rating for wind uplift to avoid a wind damage roof.

    Youll also want to consider other factors before replacing your roof or purchasing a property the age of the roof, how many layers of shingles there are, and whether the roof is properly braced and ventilated.

    A roof inspection performed by a professional can help you answer these questions and more, and you can also visually examine the roof yourself for curling or buckling shingles, missing shingles, damaged shingles, damage to the flashing or seals around the chimneys, skylights, or dormers, granules or debris in the gutters or around the ground near your home, and other signs of future problems.

    What Shortens The Life Of Your Roof

    Several things can shorten the life of your roof, including the following:

    • Storms High winds, hail, and other storm-related events can shorten your roofs lifespan. They can also make shingles curl, buckle, or come off completely.
    • Lack of regular maintenance Have your roof inspected by a qualified roofing contractor to ensure problems are detected and fixed early before they develop into larger issues. If you have a severe storm in your area or have any concerns, call your roofing contractor for an inspection. Otherwise, once or twice a year is a good inspection schedule to maintain.
    • Damage from debris Storms could cause trees, limbs, or other damaging debris to fall on your roof.

    The Lifetime of a Roof

    A shingled roof can last for several decades, but typically asphalt shingle roofing systems last for around 15-25 years with proper care and maintenance.

    That said, there are several types of shingles that could be an option for your home or property, depending on your location, budget, and preferred style.

    The type of shingles and the material that they are made which make up your roof play the biggest role in how long it will last.

    For instance, asphalt shingles dont last as long as wooden or cedar shakes.

    Asphalt shingles tend to only last for 20 years, while wooden shingles, cedar shingles, or wooden or cedar shakes tend to last for much longer depending on your region, climate, and other elements such as overhanging trees or landscaping that might pose a problem.

    Fiber cement shingles and other composition shingles can last for around 20 to 30 years.

    The type of shingle roof that you have will affect how long your roof lasts as well as when you need to consider replacing shingles or get other repairs done or do them yourself, if you are fairly handy and comfortable climbing around on your roof.

    There are a variety of guides online for performing roof repairs, so if you are comfortable with DIY you can often fix or apply new shingles to your roof on your own.

    That said, always consult a roofing contractor or roofing company if you are unsure of what you need to do or are not comfortable with clambering around on your roof yourself.

    • Composition Shingle Roofing: 12 to 20 years
    • Asphalt Shingle Roofing: 15 to 30 years
    • Wood Shingle Roofing: 20 to 25 years
    • Rubber Roofing: 30 to 50 years
    • Metal Roofing: 50 to 75 years

    These time frames can vary with the climate exposure, heat, humidity, and severe weather conditions. The better quality of shingle roofing material, the longer the roof will last and routine maintenance and upkeep can help the roof lifespan.

    What It Means To Have A 30 Year Shingle

    Asphalt shingles are one of the most popular roofing options for homeowners across America. In fact, theyre used on more than 80% of roofing and re-roofing projects across the U.S. Their versatility allows them to be used in just about every part of the country, from the hot and humid southeast to the cold and snowy northwest.

    In general, there are two types of asphalt shingles that are used: architectural shingles and 3-tab shingles. 3-tab shingles are composed of a fiberglass mat embedded in asphalt and covered with ceramic-coated mineral granules. They can typically withstand wind speeds of up to 60mph. Architectural shingles are also composed of a fiberglass mat embedded in asphalt and covered with ceramic-coated mineral granules. However, these shingles are composed of multiple layers bonded together. Shingles with multiple layers bonded together are usually more durable than shingles composed of a single layer. They can typically withstand wind speeds greater than 60mph.

    So how long do asphalt shingles last?

    Typical life expectancy of a 3-tab shingle is anywhere from 10-15 years. An architectural shingle will typically last 15-20 years. With proper maintenance and the right environment the shingles can last longer. On the other hand, with no maintenance and a harsh environment, the shingles will likely not last as long as the numbers above.
