Sound Emission of Metal Roofing

Isn’t a metal roof noisy? It is one of the most frequently asked questions about metal roofing. The theory that a metal roof is “noisy” stems from the memory of a barn, or a patio awning, where there is nothing between an individual and the roof, except air.

The more adept one becomes at answering this question, no a metal roof isn’t noisy, the more one hears the response – Oh that’s too bad, I rather liked the sound of the rain hitting my grandparent’s old metal roof. In time off homeopathic fountains and sound machines, the sound of rain pattering on a rooftop is not necessarily classified as noise.

Noise is defined by Webster’s dictionary as Sound or a sound that is loud, disagreeable, or unwanted. Sound or sound pressure is measured in units known as decibels (dB). The softest sound the human ear can detect is measured at 0 dB, while the loudest sound is registered at more than 175 dB. Existing standards indicate that sound levels should not surpass 70 dB if general conversation is desired; whereas, frequent exposure to levels exceeding 85 dB will impair an individual’s hearing. Although this is not a technical paper on acoustical concepts, it bears mention that the human ear does not distinguish variations in sound until the sound pressure level has been increased by 8 dB.

A study was conducted by The Acoustic Group at the University of Luleå, Sweden, to determine the amount of sound emitted when rain falls on various roofing materials. The study concluded that metal did not register a significantly higher sound level than shingle. In fact, the sound differential between shingle and metal was only 6 dB.

The variation of sound pressure, as it relates to rain falling on a metal roof, is dependent upon various factors. The most important factor relates to the method of construction. A metal roof installed over open framing will register a louder sound than panels that are installed over a solid roof deck. The roof deck literally absorbs or muffles the sound.

It is with few exceptions that most metal roofing products on the market today are installed with some form of underlayment material that absorbs sound. Further, in a re-roof application, metal is often installed over an existing layer or two of shingles. Considering the multiple layers of shingles, roof deck, attic air space and the insulation above the ceiling, individuals who have metal roofs say they hear the rain on their skylights, not their metal roof.

Individuals who are looking for the solace of a gentle rain on their new metal roof could be disappointed. For this reason, contractors can answer their client’s question about noise by first determining whether the customer likes the sound of rain on the rooftop. If the answer is yes, then the roof can be installed to enhance the sound they desire. If they consider the sound to be noise, then one can assure them that a metal roof is no noisier than any other roofing material.

5 Metal Roof Myths Dispelled

Article written by by Lisbeth Tanz and originally posted on October 9, 2009 at Improve Your Home And Garden web site:

Quick! What’s the hottest trend in residential roofing today? Metal. But first let’s first dispel a few myths about metal roofs:

Myth #1: Metal roofs are hot and don’t insulate the house as well as asphalt shingles.

Truth: Metal roofs actually save money on heating and cooling bills when properly installed. Depending upon the finish of the metal and the net air space created, metal roofs reflect much of the solar radiation typically absorbed by an asphalt roof. The result is a home that stays a more consistent temperature, which means no more wild temperature fluctuations throughout the day.

Myth #2: Metal roofs attract lightning.

Truth: According to the Metal Roof Alliance, a metal roof does not increase the likelihood of lightning striking your home. But if your home was hit by lightning, the metal roof disperses the energy safely throughout the structure. Besides the strike itself, the big concern with a lightning is fire. The great news is, metal roofing isn’t combustible or flammable, so it’s a low-risk and better roofing option where severe weather is a concern.

Myth #3: Metal roofs don’t last as long as asphalt shingles.

Truth: Quality metal roof workmanship warranties come with a 20-year guarantee, unlike asphalt roof warranties that are at the discretion of the contractor, says Tracy J. Scott, owner of Best Metal Roof Period in High Ridge, MO. The key to metal roof longevity, Tracy says, is a comprehensive installation by a master metal roofer. Metal roofs require special skills and knowledge to be installed properly. “Not just anyone can install a metal roof properly,” he says. “It takes at least 4-5 years to become proficient at metal roof installation–and proficient is the minimum standard homeowners should look for when seeking a contractor.”

Myth #4: Metal roofs don’t offer much benefit.

Truth: First, see #1 above. Currently, you can also receive a $1,500 tax credit on most metal roof products and/or installations that meet energy star ratings. Energy Star-qualified roof products can help reduce the amount of air conditioning needed by reducing peak cooling demands by 10%-15%. (You can find out more details about Energy Star requirements from the EPA’s Department of Energy website.)

Myth #5: Metal roofs are cost-prohibitive compared to asphalt roofs.

Truth: Metal roofs may cost more than asphalt shingles up front. However, as petroleum-based product costs go up – and asphalt shingles are petroleum-based – the cost difference is less than it was a few years ago. Typically, you can expect to pay two to four times more for a metal roof. But if you run a pay-back analysis and figure in the annual energy savings in your heating and cooling bills (depending upon the region you live in), plus the $1,500 tax credit, a metal roof can pay for itself in just a few years. Additionally, according to the Metal Roof Alliance, asphalt roofing has a higher lifecycle cost, needing replacement 2 – 4 times as often as metal roofing. And what happens when you claim frequent roof repairs on your homeowners policy? So doing an apples-to-apples replacement roof comparison requires looking at all the costs: homeowner premiums, electrical costs, and warranties. Comparatively, metal roofing can be a “once-a-lifetime” installation.

Below are the six criteria Tracy Scott recommends for homeowners evaluating metal roof contractors. He says they’re best practices that Best Metal Roof Period, his company, adheres to for professional metal roof installations that last the lifetime of the warranty.

  1. Be sure contractors you request bids from are metal roofing contractor experts.
  2. Closely related is the qualification process. How long have they been in business? How many years have they installed metal roofs? What trade associations do they belong to? What certifications do they have?
  3. Talk to the installer or the project foreman who will actually do your roofing job.
  4. Get at least 3 estimates.
  5. Ask for and check references.
  6. Demand a minimum 20-year, transferable workmanship warranty (material warranties last from 30-50 years).

In sports you often hear that the best defense is a good offense. This is especially true in the home improvement industry. “Do your homework before you spend that $15,000,” Tracy says, which is the average cost of a metal roof in St. Louis. “A metal roof will help your home appraise for up to 3% more if you don’t plan to sell right away. That’s a pretty sound investment.” His final advice? Arm yourself with knowledge so that when you talk metal roofing, you understand the language, terminology and requirements necessary for a quality installation. Don’t be in a hurry to get it done. You may be able to put up new asphalt shingles fast, but, “Just like driving a car, speed kills.”

Reducing, reusing, recycling not a fad but a reality – Excerpts

Hence my confusion. My understanding of parenting and grand parenting is the desire to leave the offspring with a brighter future, not a nasty, toxic mess of immeasurable size and unmentionable consequences.

Fast forward to today. I am in serious need of a new roof on my house. I could make the process very easy on myself and request “brown” then write a cheque. But, given my concern for the future, I can’t do that in good consciousness. Instead, I am compelled to weigh out the triple bottom line of my decision.

A triple bottom line includes the single bottom line that dominates most business transactions. Economics. Unfortunately, economics all by itself, does not reflect the full or true cost of doing any business. It never did. You can be sure that the price of trucking used styrofoam cups to St.Thomas and burying them, was never, ever considered when those cups was being made.

Back to my roof. Do I go with steel or asphalt? What becomes of the existing shingles? Will they be land filled or recycled? If they are land filled, what are the consequences? How does the process of producing steel roofing measure against asphalt shingle production? What is the expected lifespan of these products? What can I afford?

Much of the advice I have received seems disturbingly short sighted. I¹m asked why I would want to invest in a new roof that will outlive me and told, better to go cheapest. Another words, only look at the single bottom line.

Reducing, reusing and recycling is not a fad. It is our reality. Every child that you know is depending on you to use prior knowledge, take correction and stop making more of a mess of this world. Enough is enough.

Today is the first day of September. For many of us, this point in the calendar feels more like the new year than the frozen celebration that comes in January. Please use this opportunity to take a loving look at your rosy cheeked darlings. Then, take an honest appraisal at your short sighted habits. Now, make a triple bottom line resolution that will outlive you.

Heat Loss Problem

Heat loss is the term for heat that escapes through the ceiling of the home into the attic, then eventually through the roof deck. Proper air flow or circulation will have a large effect on reducing the amount of heat that escapes through the roof deck. The only way to correct a heat loss issue is through a combination of proper ventilation and proper insulation.

Root heat loss and damage caused by ice

In the illustration above, what is happening is that the snow on the roof is creating a “cold zone”. When the heat in the attic escapes through the roof deck it melts the bottom layer of the snow sitting on the roof. When this melt water crosses the exterior wall of the house, it hits another “cold zone” which then causes the water to freeze when it reaches the ice and builds layer upon layers of ice.

As illustrated, the “ice dam” allows the snow on the roof to build up which now traps the cold on the deck of the roof. Because there is a “cold zone” right on the roof deck, this can cause frost to form inside the roof and as this frost melts it will create a leak inside the house. It is important to realize that the roof is not leaking, but rather frost has formed inside the roof and is now melting the leak.

Installing metal roof is definitely the way to avoid the above problem as properly installed metal roofing provides appropriate ventilation.

Reflective Roofing

Metal is highly reflective: This involves solar radiation being reflected away from the surface.

Metal roof conducts less heat into the attic: Metal roofing, due to the air cavity behind the single and the limited direct contact with the deck, conduct significantly less heat into the attic.

Reflective metal roofing and asphalt shinglesAsphalt Shingles: Asphalt Shingles can retain heat and conduct it into the home, raising attic temperatures

Metal Panels: Metal Roofing reflect heat away from the home, keeping the attic cooler.
