RESIDENTIAL METAL ROOFING BUYER’S GUIDE

Your roof is one of the most critical components of your home, protecting both the exterior and interior. As such, it is
vital that the roof is made from high quality product, installed by a quality
professional, and comes from a reliable source. North American manufactured metal roofing
meets the highest standards for quality, safety and dependability. These products are subjected to rigorous industry standards and performance testing helping ensure your investment in a new metal roof will comply with building code requirements and perform reliably for years to come.

Don’t be fooled by inexpensive, sub-standard roofing materials that have the potential to put not only your roof investment, but your home, at risk. While it’s tempting to try and save a few dollars short-term, the higher cost
of greater repairs, the potential for roofing failure and the lack of warranty protection that come with inferior products are no bargain, and can quickly wipe out any initial savings.
Reputable manufacturers stand behind quality products with solid warranties and stringent business practices, offering peace of mind that comes from knowing your home will be well-protected, now and into the future.
Here’s what to know before you get started.

Section 1
IS IT TIME FOR A NEW ROOF?
Re-roofing your home can be a big decision, both financially and from a timing perspective. If you wait too long, you’ll cause more harm than good.
A failing roof can mean water leaks, mold and additional damage to the interior of your home. Financially, putting on a new roof typically means a large outlay of funds or a newly
acquired loan…neither of which is very appealing to homeowners. So, it comes as no surprise
that, for most people, re-roofing your home can be a stressful yet unavoidable aspect of home ownership.

So how do you know when it’s time to put on a new roof? Here are a few signs that it may be time to consider re-roofing your home…

Missing or loose roofing material…this includes either a large quantity of missing material or a re-occurring issue that has to be addressed frequently.

Damaged roofing material which may include curling, cracking, blistering, staining or breakage…anything that visually indicates the material is reaching the end
of its life.

A sagging roof…this could indicate your roof is weak and deteriorating, it was improperly installed or that it might be supporting too much weight.

With asphalt roofing, when there are large amounts of granules in your gutters, downspouts or anywhere there is water
run-off from the roof. Shingles typically lose more and more granules as they age, leav- ing the shingle unprotected. Over time the shingles become brittle and fail, allowing water to enter your home.

Exposed or loose nail heads which could mean increased susceptibility to water penetration and potential leaks in the roof.

Any water damage inside your home or attic may indicate that your roof has deteriorated. This increases the chance of mold and mildew growth which can result from inadequate roof ventilation.

Missing or damaged flashings, curbs or roof jacks increase the opportunity for water to leak into your home.

If your heating or cooling bills have gotten noticeably higher. This may be
a result of insufficient attic ventilation which may impact airflow and prevent moisture from leaving your attic. A damaged or leaking roof will also allow water into an attic. The Department of Energy states every 10% increase in moisture content within the insulation equals a 25% loss in the R-value, the ablity to insulate the home.

Depending on your roof composition, the age of your roof alone may be a good indicator it’s time to be replaced. Further, if the roof was installed over the top of the previous roof (example: shingles on top of shingles), then you may need to replace your roof even sooner.

Asphalt roofing will become dry, brittle and misshapen when aged.

Damaged or aged roof jacks may allow water leaks in your roof.

If your roof is showing any of these signs, it may be time to start planning for a new roof. This Buyer’s Guide will walk you through various aspects of the re-roofing process… from things  to consider when selecting a new roof to material  comparisons and options to questions   you should ask your roofing professional. It is our goal to assist you in your re-roofing journey and to help make your experience as seam-  less as possible.

WHERE YOU LIVE MATTERS

One of your first considerations when re-roofing
your home should be where you live. Why? Because the area in
which you live can have a big impact on your roof and its potential lifespan. Understanding
how your home’s location could impact the roof will go a long way toward ensuring you select and install a roof that can exceed your performance expectations.
Here are some important regional considerations that should impact your roof selection process.

HURRICANES & HIGH WINDS
Consider the following if you live in an area that experiences hurricanes, tornadoes or high winds.
Wind speeds – which roofing options (systems) are tested and proven to withstand high winds?
Performance ratings – what roofing products are rated to withstand the winds that could befall my area? (NOTE: there is a formal, recognized rating system in place for high winds)
Building codes – what do local building codes require as it relates to high winds?
Insurance – which roofing materials are rated to meet/exceed insurance company policy requirements?

WILDFIRES
Consider the following if you live in an area where wildfires are a possibility.
Fire resistance – what roofing materials are tested and proven to be fire resistant?
Performance ratings – which roofing materials are rated to withstand high heat such as from direct flame or embers? (NOTE: there is a formal, recognized rating system in place for fire resistance)
Building codes – what building code requirements related to flames or embers exist in my area and what roofing materials can meet those codes?
Insurance – which roofing materials are rated to meet/exceed insurance company policy requirements?

In hurricane prone areas, your roof system should be rated for its ability to withstand high winds and uplift.

Your roof can be the first line of defense when living in fire prone regions.

METAL ROOFING MATERIALS

Your roof will only perform to the level of the products from which it is made. Using sub-par products that are not designed or manufactured to defined quality standards could mean a shorter life-span for your roof as well as unforeseen complications along the way.

The MRA requires all member companies meet defined material standards. These standards are based
on verifiable testing protocol, well documented building codes and third-party research. The culmination
of standards over years of testing, performance data and research are documented in the Metal Construction Association’s Roofing Specifications which all MRA members agree to adhere to.

METAL ROOFING MATERIALS
(Continued)

SYSTEM DETAILS
Roof Substructure
The roof substructure is an integral part of the roof system. It lies beneath the metal roof panels and serves two primary functions. First, it acts as
a base to which the metal roof material is attached. Secondly, the roof substructure serves as a structural member, transferring the load to the support structure. Live loads include wind, snow, rain, and foot traffic. Dead loads include the weight of the roof materials including the roof deck itself. Most decks must also act as diaphragms, transferring wind, and other lateral forces, such as seismic movement, to the building’s structural frame.

Underlayment
Underlayment is required before metal roof panels are installed. Some panels may require both an underlayment and what is called a slip sheet. Underlayment normally comes in rolls and is available in a variety of natural and synthetic materials.

Fasteners
The metal composition and style will dictate the type of fasteners used. Each metal roofing manufacturer has specifications regarding fasteners.

Ventilation
Proper ventilation is a critical factor affecting both a roof’s efficiency and its longevity.

Curbing & Roof Jacks
Roof curbs are used to support roof penetrations such as skylights. Roof jacks are used to flash around pipes and other similar roof penetrations. Both curbs and roof jacks reduce the possibility of water leaks and provide additional protection against roof leaks.

Underlayment is a critical step in the roofing process.

Selection and use of the correct fasteners can have a big impact on the roof’s performance and longevity.

Ventilation helps balance air flow in your home, reducing the risk of mold and condensation.

METAL ROOFING COLORS & COATINGS
Choosing a color for your home’s roof can have a huge impact on your home’s overall aesthetic. With metal roofing, the color choices are virtually limitless meaning you can select from a wide variety of options or work with your installer on a custom-designed look.
Here are some dynamics to consider when selecting your roof color.
WHAT TO CONSIDER

Contrast
Selecting a roof color that contrasts with the color of your home’s exterior walls will help your home to stand out and command attention. A great example here would be a bright red metal roof on a white exterior home.

Light Colored Roof
If you are trying to add visual height to your home, a lighter color roof may make your house appear taller. For example, homes with a low-slope roof or a shallow pitch would appear taller with a lighter colored metal roof.

Dark Colored Roof
Alternatively, a darker metal roof may give the appearance of a more modest height home.

Other considerations may include your environmental surroundings and the need to blend into those surroundings.    A great example is with homes in mountainous regions where dark greens or browns help the home blend into the wooded terrain. Architectural styles may also impact the type of roof and color selection.

METAL ROOFING COLORS & COATINGS
(Continued)

METAL ROOF COATINGS

Silicone-Modified Polyester (SMP)	Polyvinylidene Fluoride (PVDF)	Stone Coated / Granular	

Siliconized polyester is composed of silicone additives in a base resin of polyester. The addition of silicone supplements the paint’s performance
by improving gloss retention and weather resistance. Some manufacturers also add ceramic pigments to reduce
color fading.

Should be applied to metal at 0.2-0.3 mil thick prime coat and 0.7-1.2 mil
thick topcoat.

SMP is considered a good paint system that offers lasting performance at a more economical price.	
PVDF paints use a resin of 70% fluoropolymer/30% Acrylic, and are considered the most durable paint in the industry. The formulation provides the ultimate protection for metal roofs.

Should be applied to metal at 0.2-0.3 mil thick prime coat and 0.7-1.2 mil thick topcoat, depending on the paint color.

PVDF is considered a higher-end paint system that offers industry-leading performance and a longer-lasting, more durable finish.	
Stone or granular coated panels, which have been formed and shaped to style, are coated with an acrylic polymer adhesive then the granule coating is applied bonding the stone chips to the specially primed steel panel. A clear coat sealer is applied over the top for extra protection during transit and installation.

Stone coated steel panels are tested to insure no more than 1% stone loss per ASTM D4977.	

SPECIAL PRODUCTS FOR CORROSIVE AND MARINE ENVIRONMENT
If you live in or near a corrosive or marine environment, metal roofing is the perfect choice for your home. For coastal applications, non-ferrous metals such as aluminum and copper may provide a better solution.
For projects near or within marine environments, the MRA recommends consulting the product manufacturer for details regarding warranty.

COOL METAL ROOF COATINGS
Metal roof coatings labeled as “cool” are coating which utilize special pigments in the paint which reflect infrared radiation and UV rays, allowing the color to appear the same while keeping
the roof cooler. These cool coatings can help in alleviating heat build-up and reduce air conditioning requirements.

Metal Roofing Alliance // Residential Metal Roofing BUYER’S GUIDE	13

METAL ROOFING PERFORMANCE
Metal roofing’s ability to perform in even the most difficult locations and circumstances makes it the best roofing choice in truly every region. How? Here is quick, simple guide to metal roofing’s performance in several important categories…

ENERGY EFFICIENCY
Metal roofing is available with “cool” coatings that can repel heat and minimize heating and cooling loads which equates to cost savings for the homeowner.

SOLAR
Because of the long lifespan of quality metal roofing products, metal roofs are the perfect platform for solar panels. In fact, most metal roofs will outlast the solar panels themselves which means the solar panel warranties will not be voided by replacement of the roof underneath. And, as an added benefit, solar panel mounts for metal roofing typically do not require any penetration of the roof itself which means less opportunity for water penetration.

NOISE
Despite the perception, metal roofing is not any louder with rain or adverse weather as compared to any other roofing material.

LIGHTNING
Again, despite the misperception, metal roofing does not attract lightning. In fact, if lightning strikes your metal roof, the electricity will be spread out across a larger area, which diminishes the immediate impact.

ENVIRONMENTALLY FRIENDLY
Metal is one of the most environmentally friendly roofing products on the market. Metal roofing is made of recycled material and is 100% recyclable at the end of its life. That means less in landfills and more reuse than with most other roofing products.

Thanks to their longevity, strength and exceptional durability, there’s no doubt that metal roofs are an excellent choice when it comes to residential rooftop solar systems.

Research has  shown  that  metal  roofing  does not in any way increase the risk of lightning striking the roof surface.

Section 7
METAL ROOFING PERFORMANCE
(Continued)

SNOW & ICE
Most metal roofing systems are designed to carry heavy weight loads, such as snow and ice. Further, several metal roofing styles encourage snow shed and minimize ice damming due to their smooth surface. Snow guards are readily available and easily fitted to every style of metal roof on the market.
HURRICANES & HIGH WINDS
Many metal roofing systems have been tested and proven to perform in winds in excess of 140 mph (equal to an F2 tornado) and provide protection against impact damage from debris.
WILDFIRES
Metal roofing, when combined with the correct roofing system components, meets the Class A fire rating. The Class A rating requires roofing systems to meet or exceed testing criteria as outlined by UL 790 (ASTM E 108) Standard Test Methods for Fire Tests of Roof Coverings.
HAIL
Most metal roofing manufacturers offer UL 2218 Class 4 compliant roofing products. This rating qualifies for the Severe Hail (SH) requirements as defined by most major insurance companies.

In summary, metal roofing out-performs most other roofing products on the market in every category. Long-lasting, durable, sustainable, low maintenance, and eco-friendly… what more could you ask for?

Section 8
DO YOUR HOMEWORK

Now that you are ready to proceed with the re-roofing process, do your homework BEFORE reaching out to
a roofing installer. It is important to note that, while the type of roof you install is critical to your decision process, just as critical is the selection of your roofing installer. For homeowners seeking a quality metal roofing installer, MRA offers these tips:

Don’t assume all roofers are equally skilled
Some contractors push homeowners towards a certain roofing material, not because it’s the best or most appropriate for their home,
but because it may simply be the option the installer is most familiar with. Make
sure your installer is properly trained, experienced and skilled in installing metal roofing. Ideally, look for a roofer that has been in business for at least five years; roofers who don’t do quality work usually don’t last that long.

Get referrals
Reputable installers are typically involved in the industry and are committed to keeping abreast of the latest trends and techniques. Check to see if the prospective installer is a member of MRA and other reputable trade alliances. Be sure to ask for and contact recent references. When contacting references, ask if they were satisfied with the work, if the process went smoothly, if the installers were careful and courteous and they did what they promised, including sticking to the estimate and change orders. Also, ask the installer to provide you with a few recent job locations so you can drive by and check out the work. While pictures may be helpful, there’s nothing like seeing how a roof looks first-hand.

Know what you want before you reach out
With metal roofing alone, there are hundreds of different options, material types, finishes and installation techniques. Request the highest-rated, longest lasting material within your
budget and always do your own research for whatever product recommendation your installer suggests, verifying it’s what you want for your home.

Metal Roofing Alliance // Residential Metal Roofing BUYER’S GUIDE	16

Section 8
DO YOUR HOMEWORK
(Continued)

K

HOMEWORK

Protect yourself
Make sure that installers are licensed, insured and carry workers’ compensation coverage. Don’t be afraid to ask for proof-of-insurance certificates and the insurance agent’s name. A reputable installer won’t hesitate to provide you with that information. Don’t pay the full amount of a job upfront; ideally, pay one-third upfront for materials, and the remainder when roofing and clean up are completed to your satisfaction.
It goes without saying that evaluating warranties is essential: make sure it covers not only materials and finishes, but leaks, flashing failures and other labor-related defects.

Be thorough
Putting on a new roof is only part of the equation. Replacing flashing, curbs and roof jacks is less complicated when re-roofing, so consider having it done at the same time if needed. Be sure to have your contractor or HVAC provider verify proper attic ventilation. Poor ventilation can cause significant damage, high utility bills and worse case, can lead to serious safety issues.
Remember… metal roofs are one of the best and most reliable ways to protect your home for the long run. Invest some time and effort upfront before your re-roofing project begins, and it will pay off with many years of loving your home’s roof.

Select the type of roofing you desire before reaching out to a local installer, including the type of roof material and color.

Make sure the installer  you  choose is a qualified, trained installer of the roof choice you select.

Referrals are important and should be easy for good installers to provide… just ask.

Require proof of the installer’s coverages (licenses, insurance, etc.) upfront. Don’t be afraid to verify
as needed.

Do not pay 100% of the roof estimate up-front. Work with the installer
on determining payment amounts based on targeted points in the project. A quality, trustworthy installer will understand that full payment is dependent on a job well-done.

Make sure you inspect the workmanship and finished product before making final payment. Don’t be afraid to question the installer about specific aspects of the final results for clarity and confirmation.

Make sure you record the important details about your roof—the manufacturer of the product, installer information, warranty details—for future reference. Also get signed, final versions of all pertinent warranties for the project.

Section 9
UNDERSTANDING THE ROOFING PROCESS
Understanding the roofing process is a vital
part of your roof replacement project. The ability to
make an educated decision when hiring a roofing professional will save you time, money and frustration throughout the process.
A moderately-sized, professionally-installed roof will follow a process similar to these steps.

INSPECTION / REMOVAL
Often a metal roof may be installed over the existing roof, eliminating the need for tear-off and disposal.
If you choose to install a metal roof, MRA recom- mends inquiring with your installer as to if the old roof must be removed prior to install. Should you need to remove the existing roof, this will require depositing the old roofing material into a dumpster or truck for removal, including old or damaged flash- ings and drip edge. A good roofing crew will protect your foundation, siding and landscaping during tear- off and will use magnetic tools to pick-up nails and metal objects from your lawn and surrounding areas.

ROOF SUBSTRUCTURE / REPAIR
If the roof deck is in good condition, only minor repairs will be required. If not, replacement of bad wood with new plywood sheathing, OSB or boards, whichever is applicable to your type of roof,
will be required.

UNDERLAYMENT / WATER PROTECTION
Install underlayment over the roof sheathing.
The layer of underlayment creates an inner barrier against water penetrating into the house. Rows of underlayment are overlapped as they progress upward toward the peak and are normally nailed in place with sealing nails.

DRIP EDGE
Apply metal drip edge round the edge of the roof, both the eave sides and gable sides. The metal drip edge is nailed in place over the underlayment.
FLASHING / CURBS & ROOF JACKS
Where necessary, apply new valley flashing along areas where two roof planes meet. The valley flashing is typically fastened to the roofing deck.

VENTILATION / RIDGE VENTS
Install the ridge vent. This continuous vent along the peak  of the roof will help air circulation in the attic space and can be integral in exhausting hot air and preventing winter ice dams. Ridge vents may not be included on older roofs but installing them can be a good idea whenever a house
is re-roofed.

INSTALLATION / FASTENERS
Installation of the roofing panel should be performed by a licensed metal roofing professional with experience installing the roof style you chose.

CLEAN-UP & INSPECT
Complete the final cleanup and haul debris away. Have the installation inspected and approved by an approved building inspector.

WARRANTIES

WARRANTIES

WHAT YOU NEED TO KNOW
Product warranties can be tricky, especially when it comes to roofing. Knowing what to look for in a product warranty could mean the difference between
a long-lasting roofing product and one that appears to be quality but, when failure occurs, ends up being worthless.

Quality metal roofing products, such as those offered by MRA manufacturer members, typically come with a 40+ year warranty on painted products. And the warranties that back these quality metal roofing products are solid, offering homeowners the assurance that the metal roof they have installed will be a “life time roof”.

The MRA encourages homeowners to get a copy of the product warranty being offered before making your final roof selection. Read the warranty details and make sure you fully understand what is being covered. Odds are high that, with other roofing materials, your warranty will not be as robust or provide the true coverage that a quality metal roof warranty can provide.

Also, homeowners should receive both a product warranty from the manufacturer and a workmanship warranty from the installer. It is important to know who is providing the warranties as well, Including the responsible company and contact information should a problem arise.

Is the warranty transferable? Does this matter to you?
Is the warranty pro-rated
(i.e. the warranty lessens over time either in coverage or amount reimbursed)?
What are the warranty exceptions? Will these exceptions pertain or negatively impact you?
Is it clear how to exercise the warranty? Is contact information provided?
Do you understand the range of acceptable performance per the warranty (i.e. what is the aesthetic variance that is allowed, roof performance in certain situations)?

In summary, the warranty is an important aspect of your roof purchase and should protect you from installation issues and/or failed product performance. It is critical

installation instructions provided by the manufacturer. Always consult the manufacturer’s instructions.

METAL ROOF CARE & MAINTENANCE
With a quality metal roof, the level of maintenance needed to maintain the roof is generally minimal, especially if the roof was correctly installed. However, performing regular maintenance and inspections of your metal roof will help ensure its longevity and aesthetic appeal.

CLEANING
During your regular roof inspections, look for warning signs such as corrosion, scratching/scuffing, leaks or debris build-up. As with any other roofing product, keeping your gutters clean and debris off your roof will help prolong the roof life.

If you need to clean your metal roof, beyond normal rain wash, a mild solution of pure soap or non-abrasive dish washing
detergent in warm water should do the trick. Washing should be conducted with a sponge, soft cloth or soft bristle nylon brush (no abrasive scourers or steel wool). A low-pressure spray may also help with removing dirt or debris.

If more rigorous cleaning is needed, other cleaning options are available. Check with your metal roofing manufacturer or installer for additional cleaning suggestions.

REPAIR
Should your metal roof need more serious repairs, such as touch-up painting or replacement, the MRA recommends reaching out to your installer. Touch-up paint is typically available for metal roofing products and the process of doing so is well defined.

BEST METAL ROOF CLEANING PRODUCTS
Plain Water
Dirt, dust, and other low-grade elements might wash off a roof with something as simple as water from a hose. Feel free to use as much water as necessary until the surface is clean.

Detergents
This is the cleaning solution that most people need to use when cleaning their metal roof because it’s non-invasive and easy to do. This category includes mild laundry detergents, car washing soap, mild dish soap, and cold or hot commercial/industrial detergents.
Mix: 1/4 cup detergent (5% detergent solution) per gallon of water
Apply solution to surface using a sponge or a washcloth
Let stand for 5 to 10 minutes
Thoroughly rinse surface with plain water
