Regular shingles are designed to provide protection against various temperatures and low wind; however,
they do not stand up well against the damaging effects of hail and high wind. Ordinary products can break and detach, often requiring continual repairs. On the other hand, impact-resistant shingles are specifically designed for intense weather conditions, particularly in high risk areas such as the proverbial tornado alley in the central United States.
Definition
Until 1996, there was no standard to specifically categorize hail and wind-proof shingles even though it was common knowledge that some materials are exceptionally durable for such weather conditions. Due to this necessity, a classification called UL2218 was developed as a joint effort by the Institute for Business and Home Safety (IBHS) and Underwriters Laboratory (UL).
UL2218 is a standard that is used to gauge the durability of a material and is conducted through laboratory testing. The materials that qualify under the UL2218 standard are then categorized from one to four, with one being the lowest rating and four being the highest. Each material is impact tested by simulating hail using steel balls dropped at speeds of ninety miles per hour. Wind resistance is also tested via a wind tunnel to simulate high wind speeds.
Properties
Currently, there are many Class Four impact resistant roofing materials that available; however, one of the most common types is modified asphalt shingles. Unlike standard asphalt shingles, this variety has properties similar to rubber which makes them more flexible and able to absorb blunt impacts and extreme bending without actually breaking.
There are many other Class Four products to choose from as well, including metal sheets such as aluminum as well as plastic and resin. Cost wise, modified asphalt remains the most affordable option being offered right now.
Installation
Installation of Class Four roofing varies depending on the type of material being used. Even those that are similar may have different requirements for installation depending upon the manufacturer’s recommendations. For the popular modified tabbed asphalt variety, installation is very similar to that of a standard shingle except that it uses six nails per sheet instead of just three per tab.
Benefits
Impact-resistant shingles cost approximately thirty percent more than standard ones and have a higher labor cost; however, they are still very cost-effective because the need for repair is nearly eliminated especially on homes located where hail and high winds are a common occurrence. Limited manufacturer’s warranties are available, averaging from thirty to fifty years which is a huge difference from the available warranties for standard material.
Using this material also has the potential to improve property value and can also significantly lower insurance premiums because it is low risk and will not likely require repair or replacement after a severe storm, unlike standard material.
In conclusion, high wind and hail-resistant shingles are a valuable investment, particularly for structures located in areas prone to such severe weather conditions. Although they may cost more than average shingles, they will eventually pay for themselves because of the decreased likelihood of the need for repairs. Hopefully this article has provided some helpful information about impact resistant shingles and the ways in which this new shingle type can be beneficial!
