What are the Main Disadvantages of Shingle Roofing?

shingle roof damage

Fixing or replacing your roof is one of the most significant investments you will make as a homeowner. Therefore it is crucial to understand all of the options available to you. While asphalt shingles are one of the most common materials currently used in residential roofing, that doesn’t mean that this is the best and only option.

There are many reasons why a shingle roof can put you at a disadvantage, including: 

  • Asphalt shingle roofing, in particular, absorbs heat from the sun and transfers it into the home. In contrast, on colder nights, it transfers heat away from your home, leaving your interior much cooler.
  • Asphalt shingle is a heavier material compared to others such as metal. 
  • The durability of a shingle roof isn’t as long compared to other roofing materials. They are easily outlasted by slate, metal, and tile and last an average of 15 to 30 years. 
  • Shingle roofing is much more susceptible to heat damage.
  • If you live in a particularly wet area, you are likely to encounter mildew problems. This is caused by excess moisture, which can cause the shingles to rot quickly and cause other damage.
  • Shingle roofs are also more susceptible to algae and mold. 
  • Strong winds can easily tear or uplift shingles off, making them susceptible to damage from high winds. Tree branches and other debris blowing in the wind can also cause substantial damage a lot easier in comparison to different types of roofing.

Are you facing one or a number of these issues? Call for a local roof inspection as soon as possible. Now might also be the perfect time to think about a roof replacement. If you need a new roof to keep your house safe and sound, metal roofing is the ideal alternative option to consider. 

Sleek and sophisticated in appearance, metal roofs come in a wide range of colors and styles to perfectly match the look of your home and neighborhood and are available as tiles, panels or shingles. 

While other roofs quickly wear and tear with age, unlike asphalt shingle roofing, it’s metal alternative gives you the benefit of proven performance expectation of at least 50+ years, giving you more for your money. They are also fire-resistant and energy-efficient, reflecting solar heat to keep your home cooler and more comfortable in the summer, lowering your energy bills while weighing less to preserve the structural integrity of your property. 

Unlike asphalt shingles, metal roofs require less overall maintenance and are tough. The natural properties of metal, and interlocking panels, provide maximum natural resistance to the many numbers of forces that can lead to roof damage such as high wind and rain.

With great options existing for nearly every budget, metal roofs offer a plethora of benefits to allow homeowners to upgrade with high-quality products of long-lasting value that are also recyclable and friendly to the environment.

Re-roofing your home is a big project, so it’s important to select the right manufacturer and contractor for the job. Here at RPS Metal Roofing, we offer top quality metal roofs in various sizes and colors, alongside state-of-the-art-equipment, and are here for all of your metal roofing needs, for the best roofing possible.  

When is the Best Time to Install a Metal Roof?

Installing a roof takes some time. Planning ahead and considering seasonal weather is therefore crucial, as damp and rainy conditions can set your installation back and cause various problems, which isn’t ideal when you are running a business or simply want a roof over your head at home.

How long does a metal roof installation take?

Your contractor should be able to give you a rough time frame for the installation and an expected completion date prior to starting. To replace a roof on a house, it takes an average time of three to four days; however, this is just a rough estimate and doesn’t consider your home’s specific circumstances. Factors which can affect roof installations include the size of your roof as well as the pitch, and of course the weather. 

What is the best time of the year for a metal roof installation in Florida? 

Living in Florida gives you the added benefit of great weather throughout most of the year, especially compared to other states in the country. This opens you up to more options time-wise throughout the year to install your metal roof. 

Winter or Spring are the two most optimal seasons to replace your roof in Florida, due to the fewest storms and hurricanes. This means that you are guaranteed to have fewer delays and setbacks due to weather. If at all possible, look to install your metal roof during the winter months. This season tends to be the least busy time for workers in comparison to spring, and the cooler weather allows for a smoother, quicker installation. Try not to book a roof installation during the summer and fall months unless absolutely necessary as this is storm and hurricane season. Without having a proper roof over your head, this could cause you to place your home or business in unnecessary danger and lead to long delays. 

The summer also brings with it intense heat and sunshine, which in theory sounds like the perfect time to install a metal roof, however, the high temperatures could potentially soften the material and result in damage during the installation. 

Either way, it is essential not to wait until the last minute and arrange a date as soon as possible to ensure that your contractors can fit you into their schedule. By planning ahead, you can also often get better deals financially, and you won’t have to deal with any of the last-minute stress and hassles that last-minute chaos inevitably brings. Keep the weather in mind when scheduling your roof project to reduce any unnecessary risks and to also protect your new room from any damage. After all, you are spending your hard-earned money, so it would be a shame for it to get damaged straight away when it could have quite easily been avoidable.

Can I Paint My Metal Roof to Change its Color?

Whether you’ve recently bought a property with a metal roof or wish to change the color of your existing roof for the sake of aesthetic and energy efficiency, painting the metal roof naturally stands out as the most logical solution for the sake of your time, finances, and commitment to living an Eco-friendly life. 

The short answer is: yes, you can paint a metal roof. However, if you wish to change the color of an existing metal roof, it’s imperative that you do it in the right manner. Here’s all you need to know.

When Can a Metal Roof be Repainted?

All types of metal roofing are suitable for repainting, but it should be noted that newly installed metal roofs should not be changed for at least six months as they need time to weather.

Before painting a metal roof, though, you must also prepare it for the process ahead by removing mildew, dirt, and any loose paint that may be left over from the original paint job. A jet power wash is the best way to achieve this, and can complete the task in a matter of minutes. 

When you want to change the color of an existing metal roof for the first time, using a diluted vinegar solution to remove any old paint oils and residue is a wise move too.

How to Repaint a Metal Roof

After preparing the metal roof through a powerwash treatment, you need to ensure that the right processes are used to paint the roof. First and foremost, the right type of paint should be selected.

Acrylic latex paint works well for bare metal roofs or painting over old paint coats. The combination of oil-based alkyd paint and a galvanized metal primer can work well too, ensuring that the paint is locked in and adhered in the right manner. With so many brands on the market, it’s important to look for a paint that offers the attributes you require. Water resistance, fire resistance, insect repellent capabilities, and UV reflection are all properties you may seek.

Application is a relatively simple task. You can use a sprayer to reach high or steeped metal roofs. Alternatively, rollers and paint brushes that are designed specifically for corrugated metal are equally capable of providing the quick coverage you crave. Only a few coats are needed, although you can usually judge this for yourself.

If all else fails, or you’re worried about safety (you should wear a harness and non-slip shoes), you can always hire a professional to repaint metal roof solutions on your behalf.

Maintenance Tips

The fact that metal roofs require minimal maintenance is a very attractive feature, and is another reason for staying loyal to this material. Nevertheless, a little work can help extend the life of your roof by several years.

Cleaning the roof once every six months with a gentle detergent should suffice. It removes debris and dirt before it has a chance to penetrate the paint or make the metal start to rust. It also provides an opportunity to identify and treat bald spots or any other early signs of damage.

You may still wish to repaint the roof once every few years to maintain the fresh look, but you’ll no longer need to worry about replacing the roof. Perfect.

Recommended Tools to Install a Metal Roof

If you are choosing to install a metal roof yourself, you must be sure that you have the correct tools and equipment in order to do this effectively. You may have purchased a do-it-yourself system, so you will appreciate that this will be installed directly onto your old roof. You must also ensure the key elements of safety when undertaking any task such as this but by using some of the best tools on the market, you can reduce your time and effort to allow you to erect your metal roof easily.

While some tools may be pricier than others, you will want to make the investment for your safety and comfort. 

Let’s start with the joining tools that you will need to use when you are installing your roof. These tools are going to be the main element of the job. Knowing what tools you need will allow you to be prepared and put together a plan of action before proceeding with the task at hand. It also allows you to learn how to use the tools and practice beforehand. These are the recommended tools that will allow you to safely and effectively install your metal roof

Fastener Drivers

These are most likely going to be needed in a job as big as this. Using a professional fastener driver will make life much easier when it comes to installation. Using a cordless impact driver will make life much easier as it will be lighter and more easier to maintain and handle. One particular favorite is the DW257 because of it’s easy adaption for metal roofing. With this modified driver, you do not need to connect it to any power supply and it is much more manageable. 

There are many cordless fastener drivers, which will also add to the safety of usage. You will find that the DEWALT cordless driver will be comforting to hold and light in the hand as the exact weight is just 3.5 lbs. It has a powerful and controlled use which makes it great for longevity and focus. 

Electric Swivel Head Metal Shears

These are mostly going to be used to cut your panels to size and trim any edges to ensure you have a snug fit to your metal roof. The recommended metal shears are the DEWALT DW890 which are very powerful little tools. Incredibly versatile, they cut through metal like butter and provide accuracy. You will be able to change speed and adjust the type of cutting feature depending on the type of metal you are using; the size and density. The DW890 is ideal for stainless steel of 20-Gauge and thinner but works well for any type of metal. You can add attachments for different types of jobs, including a drill attacher, which can come in handy. 

Nibblers 

This little tool will cut sheet metal with very minimal distortion and uses a blade that moves in a linear fashion, and will remove any small bits of metal, which may be helpful for trimming edges of your metal roof. They can directly attach onto your drill and can save time and effort. 

Blade Cutters

If you want a smooth rounded edge to your metal roof, then you are going to need a blade cutter that offers exactly this. It is best to use a blade cutter and not a handheld grinder as these can create abrasion at the edges. For the best outcome for your metal roof, you should look at a carbide metal cutting blade for a 7 ¼” circular saw as this will allow precision cuts and trims. The blades are made of hardened and tempered tungsten carbide. 

Metal Snips 

These are an essential for trimming and flashing purposes. You will find that there are snips for both right hand and left hand cuts and most good metal snips will be chrome plated rust protected forged blades for increased lifetime so you will be able to reuse them for multiple projects. They do not have to be expensive and can often be found at the hardware stores. 

Conclusion

Once you have the correct and reliable tools at your disposal, you will find that installing your metal roof will be much easier and simpler. Using the best tools will ensure that you don’t run into any unwanted issues and you can use them with ease and safety. Metal roofs are durable and weather resistant and with the rest of the necessary parts, including safety equipment and necessary nails, washers and tape, you can create the perfect long lasting metal roof. 

Metal Roof Ventilation: Gable Vents Versus Ridge Vents

Metal roofs, especially those lighter in color, can have a significant positive impact on your home’s energy efficiency and air conditioning costs in warmer climates. However, in order to maximize the cooling benefits of a quality metal roof, proper attention must be paid to the installation process, specifically ventilation. 

When ventilation is not properly taken into consideration, heat and moisture can build up in excess within your home’s attic – this can potentially cause damage to your insulation and also reduce, or fully negate, any benefit to climate control that may have been possible with the conversion to a metal roofing system. 

Two of the more common types of vents are Gable and Ridge. Each has its pros and cons, and it could be valuable to combine the two. While we always suggest first consulting a professional on any metal roof installation, here are some of the ways Ridge vents differ from Gable vents, and what you might want to take into consideration when deciding on which to go with. 

Gable Vents

A Gable roof looks like an “upside down V” and comes to a point at the top. The way these roofs slope away from the home make them beneficial for shedding water, ice, snow and other buildup of debris from collecting in one specific area – causing a higher probability in damage over time. 

Gable vents are located in front of Gable roofs and can be accompanied by fans to assist with the distribution of airflow between the roof and the attic. However, some Gable vents are purely decorative. 

Ridge Vents

Unlike Gable vents, Ridge vents are always installed with a purpose. In fact, they are located at the top of Gable roofs, typically hidden under the roof overhang with the intention of providing airflow ventilation while adding an extra layer of protection against the entry of rain. 

Should You Install Gable and Ridge Vents?

Since Gable vents can be used decoratively, they can be used in conjunction with Ridge vents. However, the benefit of Ridge vents becomes somewhat useless when coupled with a Gable vent that is not sealed off – since the benefit of a Ridge vent over Gable is the added protection against water entry. 

Choosing and Installing a Vent Type

Before committing to a style or installation of vent system for your metal roof, it is recommended to first consult with a licensed professional. In addition to offering free estimates, the team at RPS is on standby for any question you may have about the process.

How Metal Roofs Can Protect Your Home During High Wind and Hurricanes

One of the very best ways you can protect your home in strong winds and hurricanes is to install a metal roof. Metal roofs have been proven to withstand up to 140 miles per hour gusts of wind, and they can hold up against heavy rain, snow, and hailstorms. It’s for this reason that locations that are prone to heavy wind and hurricanes are having metal roofs installed. The demand is rising because of the evidence that is stacking up, showing that metal roofs are among the best protection against hail storms, embers from wildfires, and hurricane wind.

Other materials? They don’t hold up so well. Slate shingles have a Class A rating, but they don’t withstand fire and wind in the same way as metal roofs. Materials like asphalt deteriorate from the moment that it is installed, which will mean paying for re-roofing every decade or more.

Why Metal Roofs Withstand High Winds Best

It doesn’t matter where you live; metal roofing is an excellent decision to make for your house. They have an ability to resist the uplift from wind and water at the same time. This is because of three critical factors:

  • Design. Metal roofs come with two systems: hydrostatic or hydrokinetic. Hydrostatic is for low-sloping roofs, and they protect against any water due to the pressure. Hydrokinetic is for steep-sloping roofs, and they facilitate water shedding.
  • Installation. A significant factor of metal roofs working well is in their installation. You need to protect your house from wind, and with the correct installation, you get the uplift resistance that you need. It’s why the industry requires all installers to follow the installation instructions to the letter.
  • Properties. Steel is the best metal roof for hurricanes because it has the best strength to weight ratio of any other roofing material. It’s why it will work exceptionally well under the pressure of a storm. The metal itself doesn’t degrade, and when it’s exposed to the elements, you still get the benefits of longevity. Steel sheets and tiles can be coated correctly with zinc or even aluminum to prevent rust.

Those who live in areas where severe storms are frequent will benefit from metal roofing, but they’ll also be the best option no matter where you are. The resistance to the weather, water, and wind, as well as fire, is enough of a reason to get a metal roof installed onto your home.

How to Choose the Right Metal Roof Color for Your Home

Choosing the right color of metal roof for your home can be dependent on a number of different factors. Which color you ultimately decide upon may not only be an aesthetic choice. Energy savings, maintenance and other factors such as your neighborhood’s HOA may come into play.

To begin taking the right factors into consideration from the start, here is a list of items to consider when making a decision on the color of your metal roof.

DESIGN

A quality-fabricated, properly installed metal roof can combine well with any home style. However, the color you choose can make a big impact on how well your metal roof fits the overall aesthetic of your home.

A more vintage or victorian-style home may not be the suitable canvas to try exuberant or flashy colors. Staying with something more muted or era-appropriate will help keep the look of your metal roof in line with your overall home’s curb appeal. 

However, a more industrial-looking or modern-style home may offer the flexibility of experimentation with bolder, brighter colors. 

When looking at metal roof samples, it is also good to compare them during different times of day. A color that really blends well in the evening may be a little too contrasty at night, for example. 

ENERGY EFFICIENCY

Which color of metal roof you choose to install can play a key part in the energy efficiency benefits to your home. This especially holds true in warmer or more tropical climates.

In regions with lots of direct sunlight and warmer climates, lighter colors are recommended. These colors include, white, beige, light bronze, light blue, light green or peach. Choosing a lighter, Energy Star rated color & material in these cases can lead to energy savings of up to 30% over darker colored shingle and tile roofs. 

If you live in a cooler region with less direct sunlight, or have an impeccably well-insulated attic space, then darker colors can be chosen with less of a concern of impact to energy expenses.

NEIGHBORHOOD 

Depending on your neighborhood and if you need to abide by the rules of a Homeowners Association (HOA), you may be limited on the color options at your disposal. 

However, even if you do not have an HOA or other regulatory body governing your color choice, it is still a good idea to adhere to the general trends and aesthetics of your neighborhood. A color that sticks out too much from the pack and can create an eyesore and potentially even limit the interest in your home should you ever decide to sell. 

Maintaining a Metal Roof: the Do’s and the Don’ts

Choosing to invest in a quality metal roof is a decision that can result in many benefits as the owner and resident of your home or business. Energy efficiency, longevity, fire resistance and insurance savings are just a few of the rewards of owning a metal roof over standard materials such as slate shingles.

But as is the case with any quality investment, taking the time to familiarize yourself with and commit to very basic recurring maintenance can go a long way to getting the most out of your metal roof, both functionally and aesthetically.

Do’s for Properly Maintaining Your Metal Roof

1. Regularly inspect for dirt, stains and other buildup

A few times per year should suffice, but unaddressed buildup can lead to permanent abrasions and/or stains. You can choose to scale a ladder to get an up close inspection or simply use a pair of binoculars.. 

2. Use gentle washing practices and materials

Soft cloths and sponges are suggested as they are less abrasive. Additionally you should be using water and lighter cleaning solvents. One quarter cup of detergent with one gallon of water along with a soft bristled brush or non-abrasive pad should do the trick for lighter buildup and stains. 

¼ cup of bleach along with ¼ cup of dish soap and two gallons of water will help remove tougher buildup such as algae or mold while still being gentle on your roof’s surface.   

3. Keep branches clear of your roof

Regular pruning of trees and branches that grow near or over your roof will help avoid damage due to scratches from high winds and debris. A distance of at least six feet is recommended. 

4. Do touch up any scratches or abrasions

When doing a regular inspection and washing dirt or other debris, touch up any abrasions or scratches with a manufacturer-approved paint or sealant. Untreated scratches can attract more debris and cause abrasion-based damage to grow over time. 

Don’ts to Avoid When Maintaining Your Metal Roof

1. Don’t Use Harsh or Abrasive Cleaners

Gritty, powder-based cleaners can be great for agitating and lifting tough stains, but they also can result in scratches and/or paint damage to a metal roof. To maintain the integrity of your roof’s color, sealant and appearance, these cleaners should be avoided for any standard maintenance. 

2. Don’t use spray paints near your roof

This especially includes painting your home with a sprayer. But even spray painting other items should be done at a safe distance from your home or under the cover of your garage where wind cannot carry over spray. 

Any spray painting that comes in contact with your metal roof will be nearly impossible to remove. 

3. Do not walk on your metal roof too much

Metal roofs are sturdy enough to withstand walking around on, but extended periods of stress from walking can cause raised metal roofing panels to dent if you are untrained or not careful with how you are distributing weight when walking. 

Are Metal Roofs Hotter Than Shingles?

ARE METAL ROOFS HOTTER THAN SHINGLES?

No, metal roofs are not hotter than dark shingle roofs made from asphalt or other standard materials such as slate, for example.

That said, metal roofs, just like any other roofing material, will heat up in direct sunlight. But due to the reflective nature of metal, especially in lighter colors, any heat absorption is much more quickly dissipated than in asphalt, slate or ceramic shingles – all of which retain heat over a longer span of time. 

Additionally, most metal roofs are treated with Energy Star finishes which, when coupled with paler colors, can result in surface temperatures up to 50 degrees cooler than shingles. 

WHICH METAL ROOF COLORS ARE THE COOLEST?

Lighter colors tend to be more reflective and are typically the right choice when it comes to picking an energy efficient color for your metal roof. Colors such as pale blue, light green, white, beige and lighter bronze are especially good options if you live in a region that has lots of direct sunlight and a hotter year-round climate.

Additionally, the EPA has an entire list of Energy Star-certified roofing products and information available at https://www.energystar.gov/productfinder/product/certified-roof-products/

WHAT OTHER FACTORS SHOULD I CONSIDER TO KEEP MY HOUSE COOL? 

How hot your home gets from heat hitting your roof has a lot more to do with factors besides just color, finish and material. If your metal roof sits directly over a non temperature controlled room such as an attic, then insulation and ventilation will be an extra important step to ensure that heat is not gathering in a contained space.

Another benefit of proper insulation is that it will prevent your metal roof from becoming too noisy during heavy rain, hail or other inclement weather. 

Lower cooling costs are just one of the benefits of choosing to invest in a quality metal roof over shingles and other older material.
