Roof Toughness : Why You Need Class 4 Impact Resistant Shingles

Getting the Best Roof Protection with F-Wave Hail Resistant Shingles

How tough does your roof need to be?

First, consider the kind of climate youre dealing with year-round. Is hail ever an issue? Is it windy where you live? Harsh conditions often signal a need for impact resistant shingles.

If extreme weather conditions seem even a remote possibility , go for the tough stuff. You need a roofing shingle that has been lab tested by the roofing manufacturer and is proven to withstand hail and provide reliability in your building envelope. A Class 4 Impact Resistant Shingle will provide these benefits and more, including insurance discounts in some areas.

This is why you need NorthGate.

What Is The Best Roofing Option For Hail

When you think about a hail proof roof you need to consider the entire roof system.

This includes not only the roof covering material but the deck, valley metal, other metal flashing details, vent pipes and skylights.

Under typical hail-forming conditions, faster uplifting winds result in larger hailstones.

Those winds can cause the larger hailstones to travel with greater velocity.

In order to adequately protect the people beneath it, a hail-proof roof must be impact resistant and durable.

Each of the following roofs has its own level of impact resistance but you must also consider the substrate to which the roofing material is attached to.

Impact Resistant Roof Shingles: Are They Worth It

Can you think of a single person who enjoys repairing or replacing his or her homes roof? No one likes spending the time or money it takes to get an updated roof due to damage and wear.

Over time, your roof shingles experience damage and deterioration, and one of the largest factors for this destruction is the weather. Hail and wind are major weather factors that can cause extreme damage and leave your home defenseless.

Denver homes experience their fair share of winter storms involving, snow, ice, hail, and extreme winds. And with these storms, roof repair becomes inevitable. So, what if there was a roofing material that could help prevent damage from the storms and lessen your need for roof repair and replacement?

Many homeowners are replacing their old worn-out shingles for new, impact resistant shingles to help combat mother natures sting. But are IR shingles really worth the investment?

Our team at Refined Exteriors has compiled answers to some common questions about IR shingles to help you make the best decision for your home.

Benefits Of Impact Resistant Shingles

Are impact-resistant shingles worth it? For many homeowners, the answer is yes. Class 4 impact resistant shingles offer many benefits, including:

  • Meet building codes: Some local building codes at the city or country level may require you to install Class 4 impact resistant shingles when you get a new roof. Typically, these are in areas where hail is a common occurrence.
  • Get insurance discounts: Some insurance companies offer discounts on roofing materials that achieve a Class 4 impact resistance rating. For example, State Farms impact resistant shingle discount is available to select customers. These savings may be substantial, even 35% of your home insurance premiums, according to NBC News.
  • Enjoy more benefits: Impact-resistant shingles may also meet other high standards for quality. At IKO, we call these performance shingles. For example, NordicTM shingles are designed to withstand high winds up to 110 mph.
  • Achieve better durability: The most significant benefit of impact resistant shingles is that they will better withstand hailstorms. You can get peace of mind that in a hailstorm, your roof will be as safe as it can be.

Strength And Durability By Design

What Is a Hail

Non-impact resistant roofing shingles can be more easily damaged when struck by hail or other debris during a storm. Thanks to advancements in shingle design and construction, industry-leading roofing manufacturers have engineered asphalt roofing shingles that can withstand greater impact and therefore potentially reduce the amount of roof damage caused by a storm, such as hail damage.

Impact-resistant shingles are usuallyengineered in two ways:

  • A reinforcing, polymer-based mesh is added to the back of a standard asphalt shingle. This mesh is embedded into the asphalt and helps holds the shingle together, preventing the shingle from splitting when impacted by a hailstone or other object.
  • Rubber-like polymers, such as SBS , are added to the asphalt composition. The integration of the SBS polymer blend with the asphalt produces a rubberizing effect, creating a shingle that is more flexible and more capable of recovering from hail impact.

Thicker Steel Protects Better

When it comes to protecting a roof, the thickness of the metal is a key factor to resisting large-sized hail stones. Bridger Steel recommends a minimum of a 26 gauge steel roofing panel to survive a harsh hail storm. A thicker metal panel will resist punctures and form stronger seams between panels.

How Thicker Metal Helps Protect From Hail Damage

Metals thickness plays a role in its durability.

The lower the gauge number, the thicker the metal. A metal roof in a 29-gauge metal is thinner and therefore more susceptible to dents than a roof in a 24-gauge. For more protection from hail and other elements, we recommend using a thicker gauge such as 24 gauge.

Are Class 4 Shingles Worth The Extra Cost

Generally, installing Class 4 shingles is a wise investment if you live in a region that is frequented by severe weather and major roof damage is common.

In the US, a large number of residents lose their roofs due to hail and wind damage each year, but certain areas are more prone to hailstorms than others. Therefore, the higher the risk in your area, the more advisable it is to install Class 4 impact-resistant shingles.

Although their cost is 10-20% higher than the price of other types of shingles, the investment pays off in the long run. This is because the installation of such shingles lowers your maintenance costs, and may help you avoid an untimely roof replacement.

On top of that, many insurance companies provide discounts to households with Class 4 shingles, making up for the higher cost of their installation.

To help you understand how hail-prone some areas of the US are, heres the list of the states with the most hailstorms in 2019:

Texas 872 hail events South Dakota 302 hail events Colorado 294 hail events

If you live in one of these areas or in a location with other extreme weather conditions, installing Class 4 impact-resistant shingles is your best course of action.

Its possible to install a relatively cheap metal roof that will cost either the same or be slightly more expensive that a good quality impact resistant asphalt roof.

What Are Class 4 Shingles

Class 4 shingles, also known as impact resistant shingles, or IR shingles can withstand more powerful impacts than any other type of roof shingles. As a result, they are better able to protect your roof from severe leaks and various types of structural damage that require expensive repairs or early roof replacement.

Class 4 shingles are rated to resist hail impact and are designed to withstand winds of up to 110 mph. This is the highest class of IR or impact resistant shingles you can get.

To obtain this special classification, roofing shingles must undergo very rigorous testing. This test is carried out by the Underwriters Laboratory . The UL came up with the UL 2218 classification alongside the Institute of Business and Home Safety that works in conjunction with roof shingles class ratings.

The name of the test is the UL 2218 Class 4 Impact Rating test. During the procedure, steel balls of different sizes are released onto shingles at 90 mph from heights ranging from 12 to 20 feet. The balls are dropped twice onto the same area.

If the shingles under-perform, i.e. get damaged, they receive a lower rating. Class 1 is reserved for the least resistant shingles.

This table summarizes the different classes of shingles based on the performance on the impact resistance test.

Class 4 impact-resistant shingles can be made using different roofing materials, such as asphalt, metal, or rubber. Here we will focus primarily of impact resistant asphalt shingles.

What Is The Best Roof Material To Prevent Hail

Facts About the Hail and Hailstorms

At American Roofing USA, were always amazed that the largest hailstone to ever fall happened in 2010, in Vivian South Dakota. This hailstone measured 8 inches in diameter, weighed 1.94 pounds and is now on display at the National Center of Atmospheric Research in Boulder, Colorado. We also are amazed that the second highest number of hailstone-related claims in the United States took place in Colorado, from 2013 2015, totaling 182,591 hailstones. One more fact to consider is that a hailstone can fall up to 120 miles per hour.

In other words, hailstones can cause a lot of damage.

Knowing this and that roofs often take the hardest hits, which is expected as they were built with the intention of protecting you and your home, the likely question is, has a hail-proof roof ever been invented?

Hail-proof vs Hail-resistant

To begin with, using the words hail-proof, is misleading because no roof has ever been proven to be 100% resistant to the damaging effects of a treacherous storm, or other catastrophic event. So, the more accurate answer would be that there are varying degrees of incredibly hail-resistant roofs available. This includes a variety of roofing materials that do provide the greatest amount of protection while suffering the least amount of damage.

Hail-stone Resistant Roofing Materials

For instance, consider each of these products and their ability to resist pounding hailstones:

What Is The Difference Between Class 3 And Class 4 Shingles

As mentioned earlier, the impact resistance of shingles refers to their ability to endure damage and impact caused by storms and hail. The steel ball test is used to measure this resistance. Based on the test results, its easy to set Class 4 shingles apart from Class 3 shingles .

In particular, shingles earn a Class 3 impact-resistance rating if they dont crack when the ball hits them twice in the same place. On the other hand, a Class 4 impact-resistance rating only goes to shingles that dont get damaged at all in the process.

If you get a Class 4 impact-resistant material, your home will receive the best protection. Nevertheless, during extreme weather conditions such as large, wind-driven hail, theres still some possibility of damage. The shingles will protect your roof during average hail storms, but if its an especially bad one, theres still some risk of damage.

Impact Resistant Shingles Vs Asphalt Shingles

An Overview on the Impressive Benefits of Hail Resistant F-Wave Roof Shingles

When comparing the two, what are the pros to choosing the impact resistant shingles over the cheaper basic asphalt shingles?

  • Protection: Impact resistant shingles are designed to handle whatever Mother Nature sends. They are flexible which keeps the shingles from cracking upon impact.
  • Cost: Impact resistant shingles cost more to have installed, but the ROI is significant with fewer repairs, and the sturdiness during a hailstorm will save your insurance deductible. The Class 4 impact resistant shingles are a value add to any home, a bonus in the real estate market.
  • Design: Impact resistant shingles come in different colors, designs, and styles to match any architectural design.

What Are Ul 2218 Class 4 Shingles

The UL puts construction materials, like roofing shingles, through a rigorous series of tests set to determine how impact resistant they genuinely are. During this test, known as the UL 2218 Class 4 Impact Rating test, steels balls in various sizes are dropped onto the roofing material at 90 mph from 12 to 20 feet high, two times in the same spot.

How the roofing or other construction material holds up under the impact of these steel balls will determine whether they will be classified as UL 2218 Class 4 shingles or a lower class. For a UL Class 4 impact resistant rating to be achieved, the sample roofing material should be able to withstand two hits by a steel ball that is two inches in diameter without cracking or showing signs of stress.

How Impact Resistance For Roofing Shingles Is Measured

Durable Hail Resistant Class 4 Shingles

To measure the impact resistance of roofing shingles, UL performs its UL 2218 test within a controlled environment. Results provide impact resistance data for the evaluation of prepared steep slope roofing materials like shingles.

During a Class 4 impact resistance test on asphalt shingles, a 2-inch diameter steel ball is dropped from 20 feet above a shingle to simulate the impact of hail. This is done twice in roughly the same spot. A shingle passes the test if the backside does not show any visible evidence of tearing, fracturing, cracking, splitting or other opening of the roof-covering layer.

According to UL, the 2218 test does not evaluate the effect of weathering, temperature, aging or similar effects on the impact resistance of prepared roof covering materials. These and other factors, including time, roof slope, roof system configuration and application influence the performance of roofing materials in the field.
