Steel roofs are extremely popular today because of all of their attributes, including the fact that they are recyclable at the end of their lifespan. While you have been reading and learning about the benefits of these roofs, you probably have come across advice that states to remove your old roof shingles before you switch the steel roofing, and you may wonder if this fact really is true. The short answer is ‘maybe’ but there is more to it than this quick answer. It also depends on the following.
How Old Is Your Shingled Roof?
You need to remove your old roof shingles if the shingles are at the end of their lifespan. Asphalt shingles only last up to 20 years at most. After this, they begin to crack and break which means that if you leave them under a new steel roof that they will diminish the integrity of the roof’s structure.
Are the Shingles in Bad Condition?
In the event that the shingles are still in ideal condition, it might be fine to leave them to apply the steel roofing over them. However, this also may depend upon what profile of steel roofing and if leaving the shingles would interfere with the quality of its installation.
Do You Need Additional Support for Your Steel Roof Than What Is in Your Old Roof?
There is no other choice but to remove the old roof shingles when you need extra support for your new steel roof in comparison to your present roof. The roof sheathing has to be able to support the steel roofing in a sturdy fashion for you to receive a quality roof installation.
Are There Already Multiple Layers to Your Roof?
When your present roof already contains two layers of roofing, you will need to remove all of the old shingles to install the metal roofing. Three layers of roofing materials is just too much for the sheathing to support along with other determining factors.
Is the Sheathing under the Shingles Warped or Cracked?
Sheathing supports the roof materials along with the roof rafters. If it is warped or cracked, the shingles will need removing to make way for new sheathing prior to the installation of the steel roofing.
Remember that in comparison to asphalt shingles, steel roofing lasts far longer for a greater return on your investment. For further reasons that you should get rid of your old roof shingles and switch to steel roofing, consult with Johnson Roofing. We are experts in all aspects of roofing. Our company delivers quality results at affordable prices.
Expansive commercial roofs pose a challenge when it comes to selecting the right roofing materials to protect them sufficiently over the years mainly due to their lack of pitch. While there are numerous different materials that will be adequate for the task, steel roofing outperforms some of them and therefore, is one of the popular choices today for these roofs. Refer to the details below to learn more information about why steel roofing is ideal for an expansive flat commercial roof.
Longevity of the Steel Roofing
The prime reason to turn to steel roofing for a large flat commercial roof is that it lasts for up to 70 years. In comparison, asphalt tiles last 20 years max usually. Therefore, asphalt tiles are not recommended for this type of roof since you will need to replace the tiles at least twice, if not three times, to just one steel roof. This means that the asphalt roofs can wind up costing more over the years than investing in a durable steel roof.
Flexibility of Design
Since there is a wide assortment of profiles for steel roofing available today, you have flexibility of design with it for your expansive flat commercial roofs. Each profile provides a slightly unique appearance to your roof.
Low Maintenance Requirements
Steel roofing is easy to clean and requires low, if any, maintenance throughout its lifespan. You should keep a steel roof as free of debris as possible to prevent organic elements from damaging it. However, this is easy to do since elements do not adhere to steel as readily as they do with other roofing materials. If a repair is required, it is quick and easy to perform as long as it is a minor issue.
Another benefit of steel roofing is that you can recycle it when it is time for a new one. Also, your new steel roof will contain a certain amount of recycled steel. This recycling reduces the need for raw ore and the excessive energy it takes to process it into steel.
Steel Roofing Is Safe and Energy Efficient
An additional reason to install steel roofing on your large flat commercial roof is that it is fire resistant and ideal even in fire-prone areas. On top of this, steel roofs are energy efficient and can reduce your cooling costs up to 25 percent.

Metal roofs are all the rage right now, but many property owners do not know whether to select a Zincalume® or a galvanised steel one. While both galvanised and Zincalume® metal roofs are durable, there are some distinct differences between them. While some property owners will be satisfied with a galvanised metal roof, others will want the superior performance of a Zincalume® roof. Before you can really appreciate the latter choice, you must fully understand the following differences between these two materials.
The coating on galvanised metal roofing is coated with almost 100-percent zinc. In comparison the alloy coating of Zincalume® metal roofing is approximately one-percent silicon, 43.5-percent zinc and 55-percent aluminium. Even though both are coated using a hot dip method, these two roofing products perform a bit differently from each other.
Which One Has the Best Corrosion Resistance?
Since the galvanised metal roof primarily depends on sacrificial protection from corrosion and Zincalume® uses both sacrificial and barrier protection to keep from corroded, these two products have different levels of corrosion resistance. Zincalume® resists rust and corrosion in a superior fashion in test sessions. In fact, its protection lasts four times as long as, if not longer, than that of galvanised metal does in the same tests. Tests also show that both metals start off almost equal but the rate of corrosion with Zincalume® slows down as it is exposed to the weather elements since its coating forms additional barrier protection over time.
Does Zincalume® Metal Roofing Last Longer Than Galvanised Roofing Does on Structures?
Research shows that Zincalume® roofs lasts twice as long as the galvanised roofs do since the galvanised coating reduces the life of steel by fifty percent. This difference could just swing your preference to Zincalume®.
Zincalume® Roofing Is Cost-Effective
While you may think that Zincalume® would be the pricier option for a roof, it actually is quite affordable. It is not overpriced to start with, and with it outlasting galvanised steel because of its coating, you will not need to replace it as soon. For both of these reasons, you do not need to fear the price of selecting this material for your roof if it is your preference.

Often times, property owners will ignore the advice to replace their old gutters and downpipes when they receive a new roof installation only for their negligence to come back to haunt them later. What happens is that the downpipes and gutters fail to provide the ideal water drainage that their new roof needs in order to protect their structure sufficiently. Also, improper drainage can cause issues for other parts of the building. That is why when you replace your roof with a new one, you should always install new gutters and downpipes as well. If you need further reasons for this besides just our word, refer to the following details.
Old Gutters and Downpipes May Work Loose during the Roof Installation
Depending upon the complexity of your new roof installation, your old downpipes and gutters might work loose during the process. When this occurs, the water will drain off the roof in between the gutters and downpipes instead of through them. Replacing these elements at the same time as the roof prevents this issue.
Aged Gutters and Downpipes Can Leak
Another reason to replace old downpipes and gutters during a new roof installation is the fact that they might be leaking. Leaks will keep the water from draining through the right channels, so to speak, for the downpipes to guide it away from the structure. The water will drain through the leaks rather than along the intended route.
Improper Drainage Can Damage Elements of the New Roof
Insufficient drainage can damage the structural elements of the new roof, such as the fascia, roof tiles or sections, and sheathing. As a result, you will require roof repairs far sooner than you should with a new roof.
Foundation Damage Can Occur Due to Gutters and Downpipes Being in Poor Condition
One issue that can happen due to gutters and downpipes that are in poor condition is foundation damage from standing water coming into contact with the house at ground level. When the gutter system does not channel the water down from the roof and away from the house efficiently, the water can puddle right next to the house in such a way that it can seep into the foundation where it can soften and even crack it.
For additional reasons old gutters and downpipes should also be replaced when new roofs are installed, consult with Johnson Roofing. We specialise in installing high-quality NZ steel roofing materials in the Auckland area of Australia. Our company will provide a no-obligation quote upon request. Also, we issue a five-year workmanship guarantee on all of our roof installations.
One of the important considerations when thinking about installing solar panels on your house is how you need to prepare your roof for them. Most experts recommend that you re-roof an old roof prior to having the solar panel system installed unless your roof is already brand new and designed to handle the additional weight. Very rarely is the latter the case. The majority of homeowners require roof refurbishment to ensure that all is well after the solar power system is attached and operational. Below, you will discover why the experts recommend re-roofing before powering your house, at least in part, with solar energy.
The Roof Is at the End of Its Lifespan
A major reason to re-roof before installing your solar panels is the fact that you roof has reached the end of its lifespan. It is showing signs of serious wear and tear, and as a result, may be leaking in spots. There is no need to go to the expense of installing a solar panel system when your roof is in this bad of shape. Refurbish the roof first.
Your Roof Needs to Be Able to Support the Extra Weight of the Solar Panels
At times, the sturdiness of the roof with the addition of the extra weight of the panels may be in question even when it is still in good condition. The last thing you want is the sheathing to give way after you pay for the full installation of the panel system for solar power implementation.
Angle of the Roof Might Be in Sufficient to Capture the Sun’s Rays Effectively
Another reason to re-roof prior to installing the panel system for solar power is to adjust the angle of the roof when the angle is not sufficient to capture the sun’s rays in the ideal fashion for the panels to collect the solar energy efficiently. Your results with a solar energy system would be less than favourable if you install panels at the wrong angle.
Compatibility Is Another Reason to Re-Roof
Ensuring that the roof is compatible with your chosen solar panel system also is an important reason that re-roofing is recommended prior to the installation of solar panels. You will need to consult the installers to find out if your roof is or is not compatible.
For additional info about why re-roofing old roofs is recommended before installing solar panels, consult with Johnson Roofing. We specialise in re-roofing services, new roofs and services for roof maintenance. Our company will guarantee that your roof is suitable and durable enough for the installation of your solar panel system.

When re-roofing your industrial factory, you must ensure that the roofing company removes any old asbestos from it prior to installing the roof materials. While once a common material in roofs and other parts of buildings, it is now known as a hazardous material that can cause health issues and even death for those exposed to it on a regular basis. We are here to explain what asbestos is, and why it is so crucial to remove it from your structure in the following facts.
What Is Asbestos?
Asbestos is a broad term for six different silicate minerals that are found in various parts of the world. It can be reformed into a soft, fibrous consistency. Once in fibrous form, it is an effective insulation material, but also can be combined with cement, paper and other materials to increase their strength and durability. Also, it is resistant to chemicals, fire and corrosion. Unfortunately, over the years, research discovered that this substance also has been highly toxic but more about that later.
Asbestos Was Once Used Heavily in Construction
For years, asbestos was once a common material in the construction industry because of its various attributes. It was not unusual to find it in the following products:
• Roofing shingles
• Wall board
• Floor tiles
• Other construction materials
The Importance of Removing Old Asbestos
Now that we have covered the attributes of asbestos, we will explain the dangers of this material. Throughout the years of its heavy use, evidence started to emerge that asbestos was causing health issues not only for the miners who mined it, but also for others who worked with it in the construction and other industries. The reason for this is that when it breaks down, its fibres are microscopic in size and are easily inhaled into the lungs. When people inhale enough of the asbestos fibres, they can come down with serious respiratory diseases. One prime example of this is Mesothelioma, which is an aggressive form of cancer that occurs in the mesothelium membrane. Since the discovery of the link between asbestos exposure and respiratory issues, special rules and regulations have been enacted on the safe removal procedures of asbestos from structures. To safeguard yourself and your workers, you must ensure that asbestos is removed from your building prior to the installation of the re-roofing material.
For further details about why old asbestos must be removed prior to the re-roofing process, consult with Johnson Roofing. We specialise in roof maintenance, re-roofing and the installation of new roofs. If you require the removal of asbestos from your industrial factory prior to re-roofing, we ensure that it will be done so in a safe, thorough fashion.
While you may be familiar with the fact that corrugated metal roofing is ideal for flat roofs, you might not realise that it also provides benefits for sloping roofs. Yes, you can install this type of roofing material on roofs that range from low-pitch ones to ones with steep slopes. We offer you a description of these benefits in the information that follows.
Creates a Lightweight Roof That Has an Eye-Catching Design
One major benefit of corrugate metal roofing for sloping roofs is the fact that it is both lightweight and attractive. It does not require addition support like concrete or other heavier roofing needs. Also, with it corrugation pattern, it is complementary to numerous styles of houses and buildings. This type of roofing creates a clean, crisp roof that is extremely eye-catching in appearance.
Corrugated Metal Roofing Is Ideal in All Types of Climate
When you select this type of roofing, you ensure that the resulting roof is ideal for all types of climate. It can withstand heavy snow accumulation, torrential rains, strong winds and more. There is never any pooled water since the corrugation guide the water off the roof efficiently, and also due to the slope. Even low-slope roofs have an easy time with drainage with this roofing material.
Highly Durable and Long Lasting
Corrugated metal roofs come with lengthy warranties and can last up to 50 to 60 years with only minimum maintenance. As a result, you receive an optimal return on your investment. You will need to replace your roof far less often than those who choose the asphalt shingles that only have a 15-year to 20-year lifespan.
Corrugated Metal Roofing Is a Sustainable Choice
Since the metal in this roofing is recyclable, it is a sustainable option for sloping roofs. A benefit such as this helps with the production of other metal products since it reduces the need for raw materials and the extra energy to process them into usable form.
Quality Corrugated Metal Roofing Is Energy-Efficient
Corrugated metal roofing has the ability to be coated with a reflective solution. The solution helps increase the reflectiveness of the metal in order for it to prevent the absorption of heat. Your building or house will stay cooler in the summer as a result of this. You will save on your cooling costs during the summer. Also, with the right sheathing and insulation, this roofing helps the house retain its interior temperature effectively in the cooler months of the year.

When a roof contains leaks or other damage, it can fail to protect your home and for that fact, your health in the manner that it should each day of the year. That is why you must keep watch over your roof at all times and catch any minor issues before they turn into major ones that can have negative effects on your house’s structure and your health. Even one small leak can lead to you spending excessive amounts of money repairing all of the issues that can result from it when you do not take immediate action. Below, you will discover the many negative effects that roof damage and leaks can cause.
Sheathing and Attic Damage
Once your roof shows signs of leaks and/or other damage, the sheathing or decking can also suffer issues along with your attic area. Even the insulation can be ruined as a result of roof issues.
Danger of Electrical Problems and Fires
Roof leaks all water to seep into the house, and water around live electrical wires can short them out. When this occurs, electrical fires may happen, depending upon the materials that are in the surrounding area of the wires.
Ceiling and Wall Stains and Other Damage Can Happen
As water leaks into the house beyond the attic area, it causes ceiling and wall stains along with possible other damage, such as deterioration of the framework and plasterboard. In severe cases, the ceilings, walls and possibly the framework will collapse. Replacement is your only course of action to remedy this type of damage.
Mould and Mildew May Grow in the House and Might Cause Health Issues
Since roof leaks allow water to seep into the house, they also create the ideal environment for mould and mildew to grow and thrive. Many people are sensitive to these elements and as a result, can develop respiratory and other health issues. Do not be like some homeowners who have had to move out of their homes while mould and mildew remediation steps are being performed to eradicate the issues. Act quickly to prevent these issues from occurring in the first place in your house.
Other issues can occur with the foundation of the house when the roof leaks or damaged in some other way that keeps it from protecting your home in the right manner. Remember that part of the roof’s role is to ensure that water drains off the house in such a way as to not pool next to the foundation. Standing water can soften concrete foundations to the point where they can crack and possibly crumble. Once the foundations weaken the house may become unstable.
For further negative effects that roof leaks and other damage can have on your home and health, consult with Johnson Roofing. We are experts in all aspects of roofing jobs from ongoing maintenance to new roofs and re-roofing projects.
When it is time for a new metal roof on your factory or industrial building, you need to proceed in the proper manner to ensure that the roofing installation comes to completion in a quality, safe fashion. In order for you to prepare correctly for a new metal roofing installation, we offer you the following steps to take prior to the project taking place.
Hire a Reputable Roofing Company
The first thing on your agenda when preparing for an installation of a metal roof is to hire a reliable, quality roofing company. Also, ensure that the company specialises in roofs for factory and industrial buildings to receive the best results. Any company that you hire should also carry full-coverage insurance and correct licensing to work in your area. If you interview more than one roofing company, be certain to compare quotes and check references to learn which company will deliver the ideal results.
Select the Style and Colour of Metal Roofing
With the help of the roofing company, select the style and colour of metal roof that complement your building in the most favourable way. When pertinent, choose the roof profile that is compatible with your solar power system.
Sign All Pertinent Agreements
Read over and sign all necessary agreements once you agree with their terms. Be certain that there are no hidden fees or terms before signing any agreement.
Clear the Area Around the Building
Another important task to perform prior to your new metal roofing installation is to clear the areas surrounding the building to ensure that the roofing crew members have unhindered access to your building. After all, they will need space to place their equipment and supplies.
Protect the Upper Floor When Necessary
You also need to protect the upper floor if the sheathing or decking is going to be replaced as part of the metal roof installation. This upper floor could be no more than storage but may house some of your offices. Either way you might need to move some belongings and cover the floors and walls until the installation comes to completion.
Ensure That Safety Measures Are in Place
Do not let any metal roofing installation begin before the proper safety measures are in place. Warning signs that work is going on alert pedestrians, visitors, clients and employees to the fact that caution is necessary. Also, the walkways should have covered scaffolding on them to allow for safe travel to and from the building. This protects people from falling objects.
For additional preparations that you should do prior to a new metal roofing installation, consult with Johnson Roofing. Roofing is our business, and we deliver high-quality results to commercial, industrial and residential clients.
