How Long Does a Metal Roof Last? (Screw Down and Standing Seam)

With certain types of metal roofs, yes, metal screws do come off over time, and it happens to homes that have an exposed fastener metal roof.

The reason why most homeowners choose a metal roof is to avoid common maintenance problems with asphalt roofs.

But what homeowners need to know is, is which type of metal roof is best and not get talked into something that theyll end up regretting later on in the future.

Question : Should Homeowners Still Make The Switch To Metal Roofs In The Future Is It A Trend

That all depends on your roof, house, neighborhood, location, and financial situation.

A metal roof doesnt fit into every neighborhood, and it just doesnt fit into every house. Not all homes will look good with a metal roof install, and that can hurt your curb appeal.

It depends on your location too. Here in Austin, people tend to be more conservative and stick with asphalt roofs whereas up in Dallas, homeowners opt-in for the higher end types of roof, and standing seams happens to be the one they like.

In general, making a switch from an asphalt roof to a metal roof is no easy decision for locals here.

But as far as it going into the future?

We believe more and more homeowners will begin to make the switch here in Austin.

What can make the decision much more comfortable is for homeowners to know who theyre dealing with, and only speak to a reputable local roofing contractor who knows what he or she is doing.

A good contractor should be able to educate you, guide you, and give guidance in your best interest. If theyre a bit pushy, you should proceed with caution.

Because at the end of the day, you dont want to be pushed into a $35k metal roof and have to go and replace it in a couple of short years.

Because with a metal roof, once theyre put on, theres really not an easy way to repair them.

More About Lightning Strikes

Knowing more about this natural occurrence can help you better understand lightning strikes that occur in our lives. Lightning has been studied for hundreds of years now, and we have a pretty good base of information about it. What is unknown is how it forms and where it strikes. This makes behavior unpredictable.

Lightning is actually a rapid discharge of atmospheric static electricity. As such, three major types of lightning strike can occur: cloud-to-cloud discharges from a highly-charged cloud into a less-charged cloud Intra Cloud discharges inside of a single cloud from a highly-charged area in the cloud to a less-charged portion in the cloud, and cloud-to-ground discharges from a cloud that is highly-charged down to the earth.

We best understand CG, which is the type we are most concerned with when it comes to property and life. While there is uncertainty about where lightning discharges appear, the exact location depends on the storms topography, geography, and movements. When lightning is ready to discharge, it simply will. This happens whether there is a roof in the area or not.

There is faulty logic at work in assuming that metal roofs attract lightning strikes similarly to a lightning rod. This is because lightning rods are not actually made to attract lightning. They are made to channel that lightning safely to the ground if and when a strike hits the building.

Selecting The Correct Thread Count

Thread count, also known as thread pitch or threads per inch , represents how fine the threads are on a screw. This is an important consideration because its part of what determines the pull out values of the screw

US fasteners refer to the thread count as threads per inch so 24 would represent 24 threads per inch. Example: #12-24 is a #12 diameter with 24 threads per inch.

Metric fasteners refer to thread count as thread pitch, or the distance between the threads. For example, a 1.5 pitch would have 1.5 millimeters between each thread.

Smaller fasteners tend to have finer threads, so the thread count is higher.

This is why having the right materials in place is essential. Again, people get confused since metal is a conductor, thinking that it makes for unsafe roofing material. But the fact of the matter is that the exact opposite is true.

Since metal is a conductor, it actually spreads out the force of the electricity rather than focusing it in one place. For this reason, the strikes full impact will be diffused. The electricity from the strike will travel nearly instantaneously through those conductive materials straight to the ground.

Did you know that the average lightning strike lasts only 30 microseconds? If your building materials are more likely to combust, the results of a strike are more often than not a destructive fire. When using metal and steel as building products and also pairing them with fire-resistant materials, your building will be much more likely to stand up to a lightning strike than those wood-framed buildings that permeate your neighborhood.

    Tin Roof Vs Shingles Lifespan

    The length of time any roofing lasts depends on location which can affect UV exposure, precipitation, temperature extremes, airborne salts and chemicals, wind forces, organic debris, and pollution. The greater the exposure to any or all of these, the faster the roofing will degrade. However, asphalt shingles will deteriorate more quickly than metal roofing in the same environment.

    Where I live, the common adage is: buy 25-year shingles and hope for 12, whereas most steel roofing will last 40 to 75 years or more. Plus, SMP or PVDF coated steel will resist fading or chalking for 35 and 40 years respectively, so steel roofing will easily last 3-times or more longer than asphalt shingles.

    Asphalt shingles are less expensive and easier to install than steel roofing. The overlapping multi-layer aspect and the fact that shingles dont expand or contract with temperature is a great preventative against leakage. Unfortunately, pollution, organic debris, wind, and other climatic issues can cause the shingle to curl, warp, and crack, exposing the roof structure to moisture.

    Steel roofing, if properly install and maintained, also is an effective barrier against leakage. However, wind, snow, and ice, along with temperature extremes can damage seals, screws, and washers, resulting in leaks hence the need for regular and proper maintenance. While the asphalt shingle has to be replaced, the steel just needs a new screw or sealant to make it as good as new.

    Reasons Why Exposed Fastener Metal Roofs Are Problematic For Homeowners

    What happens is an exposed fastener metal roof is always exposed to extreme heat and cold year-round and causes the metal to expand and contract regularly and loosen those screws up.

    Also, exposed fasteners have neoprene attached on top base of the screws to prevent water from getting into the roof. What happens is the heat and cold also affect the neoprene causing it to dry up and eventually cracking. These cracks will open up holes that allow water to flow right through and cause leaks and other damages to your roof.

    You wouldnt think water can get through a little screw hole, but they do.

    Worse case is multiple loosen screws and cracks in the neoprenes on those screws. Youd be looking at a big problem if that were the case.

    We recommend that if you have an exposed fastener metal roof, its best to get it checked every ten years or even sooner.

    Its very likely that in 10 15 years your exposed fastener metal roof is going to need a re-screw.

    Because this often happens to exposed fastener metal roofs, its not the best type of metal roof for homeowners.

    If youre a homeowner looking for a metal roof, youre going to want to go with a standing seam metal roofs because the screws dont come off, and there no maintenance required at all.
