Hail Damage Restoration Time is Time for Improvements
In many states in the US we are approaching hail season. For those that live in areas that are prone to these storms, they know that in a matter of minutes their house could be torn up. Hail the size of golf balls can come down smashing windows, siding, and damaging asphalt roofs.
After the storm, people are frantic about how to fix their home. Too many of them, however, go through the restoration process and put the same product onto their home that was just damaged. The next storm to come could well destroy that new roof. 😉
Hail damage restoration is necessary, but upgrading to a better product is even more important.
Hail Damage to Asphalt Roofs
In the U.S., around 80% of roofs are topped with asphalt shingles. They are cheap, quick to install, and for the most part they look pretty good on top of houses. The problem, however, is two-fold. Asphalt roofs will wear out over time, and they are susceptible to hail damage (as they get older, smaller and smaller hail stones can damage them).
With hail storms increasing in frequency and intensity, the likelihood of your newly replaced asphalt roof being damaged in a storm is pretty high.
Fortunately, there is a better way; instead of restoring your roof, improve it!
There are not many roofing materials that can match the longevity, durability, malleability, flexibility, resiliency, and cost-effectiveness of Zinc. Not even aluminum nor copper! Zinc roofs are known to last for hundreds of years, even in the most extreme environments. Truly unmatched durability, longevity, and classic beauty — that’s what Zinc roofing offers to a homeowner. At $12 to $15 per sq. ft. installed, it is the kind of value that is simply unmatched in all other roofing materials.
Zinc – Most Amazing Roofing Material You’ve Probably Never Heard of
In the US, the whole idea of using Zinc as a roofing material for a house sounds other worldly. Aluminum and Steel dominate residential metal roofing market, while asphalt shingles are by far the most popular overall roofing material. When you also factor in natural slate, clay tiles and cedar/wood roofing options, Zinc barely registers on most people’s radars. Though this trend is changing, slowly.
Did you know? 70% of residential roofs in Europe are covered with Zinc. In Paris, this number goes up to 85%.
Metal roofing is often chosen for its durability and longevity. All properly designed and correctly installed high-end metal roofs are likely to last at least 50 years. Yet, in order for that to hold true for Steel, for example, it must be coated with metallic finishes such as G-90 or Galvalume, along with high quality paint finishes such as Kynar 500. With Zinc, as well as copper, that is not the case.
Both Zinc and Copper form protective patina, meaning they will not rust nor be adversely impacted by weathering. Both of these metals benefit from aging, and their patina process. With Zinc, it starts out dark, as in dark gray / near black and then changes to a patina light gray or bluish color. Zinc can also be painted virtually any color, which serves as a sacrificial layer prior to the patination process.
Did you know? Thanks to Zinc’s naturally forming self-healing properties, it can provide years of virtually maintenance-free roof and building envelope protection
What makes Zinc truly fascinating is its resiliency. All metal roofs, including Zinc, can be scratched. With Steel, scratches in its coating layer will expose the base material to the effects of oxidation and corrosion. With Zinc, it actually self-heals. You read that right, Zinc if scratched will self correct. The protective (patina) layer of Zinc is technically hydroxyl carbonate that will, over time, reform itself and thus eliminate blemishes or scratches. This is one, of a few reasons, why the market for Zinc will often sell pre-patinated Zinc roofing.
As you may have guessed, Zinc is extremely durable. When steel is “galvanized” it is really just adding a protective layer of Zinc to the Steel base to protect it from oxidation, as Steel is naturally corrosive, or will rust when exposed to salt, water, or moist environment over a long period of time. Galvanized and Galvalume Steel will forgo that aging for a couple of decades.
Like most metals, Zinc is insect-proof, fire resistant, and mildew / fungus-proof. Zinc also benefits from being non-toxic. Because of its low to non-existence toxicity level, soft zinc is marketed as replacement for flashing material for all roofs. Back in the day, the traditional material was lead, then steel, but soft zinc, offers virtually the same level of durability with no known toxicity impact.
Run-off water from Zinc is considered ‘clear’ or contaminant free, which most metals can’t readily claim. Thus, a zinc roof is a great option for homeowners interested in rain water collection.
Like many other metals, zinc is fully recyclable. Plus, it will reflect solar radiant heat, as most metals do to some degree, which prevents the unwanted transfer of heat from the roofing material into the attic space. Note: Asphalt shingles gain a lot of heat during the day and transfer much of it inside your home.
Moreover Zinc has even greater environmental value in that it takes less fuel to manufacture it, really to boil it and shape it into finished roofing product.
Did you know? Aluminum and steel use a good two to four times the energy in their production as compared to Zinc!
All this value would make you think it’s gotta be at least as expensive as Copper. Nope. Not necessarily.
Installation Costs and ROI for Zinc Roofing
Copper averages around $20+ per sq. ft. when installed as roofing. By far the most expensive metal material sold in the residential market. Steel can be had for as little as $6 to $10 per sq. ft. installed depending on the system. Aluminum installed can range from $7 to $12 per sq. ft. Zinc comes in at only a slightly higher price point $12 to $15 per sq. ft. installed.
The biggest bang for your buck. That’s what Asphalt Shingles on a roof can provide to you, the homeowner. It’s not the most durable material. Durability and longevity belongs to metal roofing and natural slate. For the value, though, Asphalt Shingles are hard to beat, especially when viewed through the prism of its low upfront cost and near-term home improvement ROI. An asphalt shingle roof can often be installed for under $10,000 on a small or mid-sized single family house. For a relatively modest upfront cost, you can expect to get at least 10 to 15 years of roof protection for your home.
A Wee Bit Of History
For a long time, slate tiles were the cream of the crop when it came to roofing a house or building. In the early 20th century, that changed. America went from using slate and cedar (wood) shakes and shingles as predominant materials for covering their homes, to what was at the time the newly unveiled asphalt shingles. The reason for this was two-fold; The new asphalt shingle was made to look very similar to the slate tile, but at a much more affordable cost. Like all things mass production, it allowed millions of homeowners to enjoy decent roof quality without the need to spend a whole lot of money on a roof. Yet, like many things associated with mass production and usage, it lead to a significant, and ongoing issue with the disposal of old asphalt shingles.
Understanding Asphalt Shingles Roofing Options
Back in the day, it used to be that asphalt roofing was rolled onto roofs. Cloth-like paper, with layer of asphalt, coated with stone granules. In the early 1900’s, the rolls were sliced into individual pieces. Add in the political pressure from the National Board of Fire Underwriters, who thought this material was much better for a home covering than the popular wood shakes alternative, and a monumental industry was born! 😉
Strip shingles, or what we call 3-tab today, used to be the standard for nearly half a century. They offer a single layer, uniform look for the roof. They are light-weight even in today’s market. But, they are considered cheap and less durable than the next step up, or what we call architectural shingles.
Architectural Shingles are thicker, heavier and offer far more variety than their predecessor. With 50% more weight than a 3-tab shingle, architectural shingles come at a higher cost. Though, the cost is easily justifiable with more durability, service lifespan and the idea that shapes of shingles can be different. Architectural shingles are also known as laminated or dimensional shingles, because there is an appearance of more depth to the roof than what 3-tab/strip shingles provide.
Many routinely refer to architectural as the premium product, but they are really middle of the road product.
Premium shingles can offer even more depth and variation. These are luxury shingles are known for their totally different look. Truly premium shingles are designed to be as durable and long lasting as possible. Here, multi-colored options exist, along with cool-roof asphalt shingles, and other cutting edge technological advancements.
To be clear, the architectural shingles are the predominant product in the asphalt shingle market today. The other two options are also being sold, and are quite popular in their own right. 3-tab makes for a great starter row on any type of asphalt shingle roof. Plus 3-tab is sufficient wherever economical considerations may outweigh quality, such as on some low-priority commercial buildings and value residential roofs. Premium shingles are deemed by many as too luxurious, but there are people willing to pay nearly twice the cost for a better designed, longer lasting roof, which the luxury shingles provide.
Another consideration which each of the three options has to do with how the product can perform during storm weather and strong wind uplift. Essentially, the cheaper the product the less wind it can withstand before the 3-tab tiles curl or are even blown off. This pertains directly to product warranty. Here’s a quick rundown:
3-tab shingles are rated for 60 to 70 mph wind uplift, usually holding to a 20 to 30 year product warranty
Architectural shingles are rated for 110 to 130 mph winds, with 30 to 50 year warranties
Premium shingles are rated for up to 110 mph uplift, and usually come with limited lifetime warranty
