Metal roofs aren’t just for commercial construction anymore. As homeowners’ demand for low-maintenance, durable roofing options grows, metal roofs have become an appealing alternative for residential projects. In fact, 14% of the residential market was comprised of metal roofing in 2016. Now that number has nearly doubled, and as metal roofs continue to surge in popularity among homeowners, more textures, shapes, colors, and designs are being made available.

So what makes metal roofing such an appealing option for homeowners? Metal roofs can last 40-70 years, which is a significantly longer lifespan than more traditional options like asphalt shingles. They can also withstand certain extreme weather conditions, such as wildfires, lightning strikes, and wind gusts of up to 140 miles per hour.

Metal roofs can also lower energy bills by reflecting unwanted heat in the summer and increasing insulation during colder months. Plus, finishing a metal roof with a durable coating allows for an even wider variety of colours, textures, and design options.

Metal roofing has claimed a spot in the roofing industry as one of the leading customer preferences for roof replacement. How did this material rise to fame in the recent years? Read on below to find out.

Continuous Annual Growth

The continuous growth of metal roofing began in 1998, when the Metal Roofing Alliance (MRA) created a national consumer awareness campaign. They found that the metal roofing market had approximately 3.7 percent of consumers. Since then, the metal roofing industry has received growth in the residential market because of the agency’s efforts in disseminating metal roof information.

Popularised in Various Regions

According to a data supplement from Dodge Data and Analytics, metal roofing has increased its popularity ratings. This company is also behind some of the best product and service statistics, such as the consensus behind preferred fibre cement siding repair services. Some regions showed rapid growth, such as the Pacific, East South Central and Mid Atlantic.The largest market share in metal roofing is the East South Central region, with a metal roof installed on over 30% of residential houses.

Recent Market Aspect

As the demand for metal roofs grows, the market share for other popular roofing products such as asphalt roofs decreases. In 2016, asphalt dropped down to 59 percent, from a 64 percent market share the previous year. Metal is enjoying its current popularity as a roofing material among home and business owners because of its durability and versatility.

If you have ever done any kind of repairs on your roof, you know how much effort it demands. From standing on the ladder trying to repair something to the noises that everyone in the house can hear, it is unforgettable experience. It can be especially stressful when you need to go up into the roof and fix something there. Luckily, you do not have to do everything yourself. You can get an roof inspection done by a professional which is much safer method of repairing the roof. Below, you can find the biggest benefits of having a professional roof inspection services in Auckland.

Detect Water Damage

Of course, you do not need a professional to find large leaks but other forms of water damage are almost impossible to find with the naked eye. This can prevent you from dealing with the problem before more leaks appear. Professional inspection can help you prevent this. These inspections let professionals detect moisture damage and problems with structure of the roof that would have gone unrepaired otherwise.


Even though performing repairs by yourself is cost effective in a short term, hiring a professional to inspect your roof can save you a lot in the long-term. These inspections can help you detect hazards, prevent you from paying a lot in the future to repair leaks and protect the items inside your house from damages. Not to mention the fact that if you have large leaks, you may have to leave the house until repairs are done. As a result, the ability to find problems early can save a lot of time and money by preventing you from leaving the house due to serious roof damage.

Moreover, professional inspection is pretty accurate, so you can also save money on roof maintenance in the future. When severe roof problems happen, the only option is to replace the entire roof. However, professional inspection can help skilled workers identify spots that need attention, repair specific areas of the roof and leave the rest of it untouched during the repair process. This can save homeowners a lot of money by preventing them from replacing the entire roof and by allowing fixing sections that have certain problems.

Great Protection Against Unseen Roof Damage

Because the roof suffers different weather conditions and sunlight, it is inevitable it will need repairs. Rain, temperatures and snow are continuously affecting the structure of the roof. However, these processes are slow and happen gradually so there can be a problem in the roof for a long period of time before it will be noticed by the homeowner.

Only a professional can inspect the roof in a way that all unnoticed problems will get necessary attention. Contractors have the experience and knowledge to identify and treat non-apparent damage. Thus, they can conduct necessary repairs before major problems appear.

Helping Your Insurance Claim

If your house has been through the storm or something else happened and now you need to make an insurance claim, you can ask a professional inspector to carefully asses the roof damage you have. Insurance companies often ask what kind of damage your roof has, so it is always nice to have a report from a specialist that can help you in that regard.

Help Extend the Life of Your Roof

By performing routine inspections of your roof, you can mitigate damage that is slowly occurring in your roof. Regular inspections and minor repairs ensure that the roof structure will last much longer. By preventing damage, the roofing contractor reduces the amount of effort, time and money you will spend on repairs in the future. By extending the lifespan of the roof, professional contractors postpone the need for costly repairs and roof replacement.

To prolong the life of your roof and ensure water doesn’t leak through, your home’s roof should be inspected twice a year. Once in late spring, and once during the autumn. Below is an autumn season roof maintenance checklist.

Trim the Trees

Dead tree limbs can fall on your roof and cause damage, especially when it’s raining or snowing. Trees that are leaning towards your house could also fall on your roof or allow squirrels and raccoons to pay your roof a visit. Twigs, leaves, and other debris can cause rotting, gutter blockage, termite invasion, and roof damage. If you want to avoid these problems, remove overhanging branches and ensure that trees aren’t leaning towards your home.

Gutter Cleaning

Check and clean the gutters. One of the best ways to prepare for the cold season is to clean your gutters and ensure they’re well-anchored. This allows rainwater and thawed snow to flow properly off your roofline, avoiding leaks and water damage to your home. So remove leaves and other debris from the gutters regularly throughout the fall. In addition to this, install gutter guards – these ward off any debris that would invade your gutters.

In some situations, water from overflowing gutters can pool around the base of the home and damage the foundation. For example, the heavily saturated soil puts pressure against foundation walls, which can cause them to crack. Pooling water from blocked gutters can also cause the foundation to settle, and that may trigger a chain reaction throughout the home, cracking walls and creating uneven floors.

No one wants to spend a fine autumn afternoon scooping muck, gunk, and leaves from the gutters. It’s a time-consuming task—and it can be dangerous if you’re not careful. Seal out debris but allow water to flow through gutters. The result is maintenance-free gutters that won’t cause leaks, back-ups, and other headaches.

Damage Inspection

Check the roof flashings. They are these cover gaps near vents and chimneys, and can be dislocated during a storm. Replace faulty flashing pieces. If you have an asphalt roof, replace shingles that have bare spots, are warping, or are curling at the edges. If you own a wooden shake roof, look for signs of warping. If at least 25 percent of your wood shingles are damaged, replace the roofing material. If you have a metal roof, look for signs of pitting, corrosion or gapping seams as these can lead to leaks or underlay damage.

Sometimes a factory roof can naturally reach the end of its useful life without experiencing a roof failure. It just looks old and worn, and you are doing preventive maintenance on your home. If replacing an old factory roof is delayed, however, it could result in bigger problems down the road. So watch for the warning signs to be sure to give yourself plenty of time to add the reroofing project to your to do list. Below are factory roof leaking issues that tell you need to re-roof.

Factory Roof Caused Stained Ceiling or Walls

Whether you have ceiling tiles or other types of ceiling systems in your facility, extended exposure to water will create a discoloured area of your ceiling. If the leak is near a wall, the water stains could run down the corresponding wall, if this is the case, there could also be water damage within the wall.

Factory Roof Has Odour or Mould

A foul smell in your facility could be a red flag for hidden mould. Mould grows in moist environments, so if water is constantly entering your building, there is a high chance that mould could grow and spread. A mould problem in your commercial facility should not be taken lightly as it could cause illness.

Factory Roof Has Dark Streaks

Airborne algae cause dark streaks on roof decks. While this may not necessarily harm the roof shingles, it may not look good. Algae streaks can be removed using a 50:50 blend of water and bleach sprayed on your roof. It is important to use a low volume garden hose so you do not knock the protective granules off your shingles. It is also important that you protect your landscaping from the bleach run-off.

Factory Roof Has Moss Overgrowth

Moss can grow on roof surfaces that don’t get much sunlight, especially in cool, moist climates. Moss growth can be more than a cosmetic issue. Moss holds moisture against the roof surface and overtime in freezing climates can cause damage to the granules on the top of the shingles. Moss can be brushed off but it won’t prevent it from growing again; take care not to damage the shingle surface. You may need to contact a professional roofing contractor.

Commercial and residential roofing, while serving the same ultimate purpose, have their respective differences. These differences are essential to know which one is the right option for you. Peruse the following differences between commercial and residential roofing and know which one is fitted to your needs and preferences.

Commercial and Residential Roofing Structural Needs

The structural needs of a commercial roof are different from a residential roof. Obviously, commercial roofs may be considerably larger – imagine the size of a roof on a shopping mall compared to the size of the roof on your house and you’ll get the picture. In addition, the load requirements, fixtures, and even materials will vary significantly between commercial and residential roofs. For example, commercial roofs must have a larger load-bearing capacity than residential roofs often just because of the materials involved in their construction. Similarly, installation of a commercial roof requires a much larger crew than residential roofs simply because it’s a bigger job.

Commercial and Residential Roofing Functions

With respect to the function of the roof, commercial roofs tend to have more protrusions than residential roofs. While a residential roof may need to accommodate chimneys, skylights, and a few other protrusions, commercial projects must also consider ventilation systems, smokestacks, pipes, roof entrances, and mechanical needs. Likewise, there are specialized construction specifications for commercial and residential roofs. For example, commercial roofing materials are often chosen based on the function of the commercial building; if the commercial building features heavy machinery, the roofing material must be able to withstand heat discharge. On the other hand, residential roofs are generally constructed with respect to the homeowner’s personal preferences regarding appearance, durability, and maintenance.

Commercial and Residential Roofing Project Scope

Whereas commercial roofers must consider the function of the commercial building and the unique specifications that affect the roof’s construction, residential professionals must be informed about the particular needs of their clients. Obviously, both types of roofs must be constructed to withstand the climate of the region, but residential types tend to be constructed with an eye for aesthetic and commercial roofs with a mind on functionality.

Commercial and Residential Roofing Needs

Most importantly, because of the differences between the two types, you will find contractors have different needs as well. Commercial roofing is generally considered a much more involved if not difficult job and finding skilled laborers for the work may contribute to the cost of projects. The fact that these projects tend to be considerably larger than residential projects also means that commercial crews are larger, and many residential contractors cannot accommodate the manpower needed to complete a commercial job.

Today, the average cost of replacing a roof can be considered as an expense that lies way over the budget. For such a costly investment, you need to make sure that you choose the right contractor as well as materials for your reroofing project. Aside from that, there are so much more to keep in mind so as not to render your project obsolete and dysfunctional. Below are items to consider before proceeding to your reroofing project.

Inquire about Reroofing Project’s Proposed New Ventilation

Proper ventilation has a huge impact on your roof’s longevity. Improving your roof’s ventilation helps regulate the attics temperatures during the summer and minimises moisture accumulation in the winter. Ask your contractor whether they will include such features as gable and ridge vents.

Ensure that your Reroofing Project Maximises Energy Efficiency

An energy-efficient roof helps lower your energy bills as your air conditioning unit does not have to work exceptionally hard to cool your home. Cool roofs are normally made of materials that do not easily absorb the sun’s heat. Apart from keeping your home’s interior comfortable, this also reduces the roof’s maintenance costs. While in the past such roofs were mostly made of bright colours, dark hues are now becoming available.

Consider Installing Low Maintenance Gutters for your Reroofing Project

Misaligned and unsightly gutters will probably not augur well with your new roof. Choose a roofing company that provides low-maintenance and preferably, seamless gutters. Choose gutters that are not held in place by gable overhangs or eaves as these are susceptible to water damage.

Consider Installing an Airtight Chimney Cap for your Reroofing Project

Although chimney caps are quite inexpensive, they are often overlooked. A chimney cap reduces the energy consumption in your home by preventing heat from escaping and keeping snow, sleet or rain from getting into your home. It also prevents animals such as raccoons, squirrels, birds, mice, and rats from accessing your home.

Prevent Ice Dam Formation by Installing Eave Flashings for your Reroofing Project

Eave flashings are your roof’s unsung heroes. This is a thin weather-proofing material which, alongside your roof’s underlayment, prevents moisture from getting to the shingles. Eave flashings also prevent the formation of ice dams.

Reroofing is one of the home improvement tasks that homeowners are not prepared for. Most of them rely entirely on the durability of their roofs that they forget to save up for a rainy day. What they fail to consider is the fact that reroofing commonly costs a lot and minimising such expenses might be a budget struggle. Luckily, below are reroofing tips to ensure you won’t go beyond your budget.

Off-Season Advantage

Reroofing requires good weather, and most contractors stay pretty busy through the warmer months. Depending on your climate, tackling this project at the end of winter or the beginning of spring, when it’s still a bit dry in many areas, can leave you room to negotiate the price of the project. In some cases, late fall is often a slow time for many contractors, both due to the changing season and the upcoming holidays, when most families aren’t focused on home improvements. You may need to be flexible with work schedules due to weather, but you can save a significant chunk of change.

Project Planning

Proper planning is the key to any successful home renovation project. In the absence of a solid plan, you may end up making decisions you cannot sustain. When creating a project outline, you will need to consider your roof’s pitch, house size, damage severity, and roofing materials. You should also get a rough estimate of how much your project will cost by contacting several roofing contractors. This enables you to compare notes and narrow down your options to what would suit your budget.

No Sudden Changes

Making changes after the roof replacement project has already begun may not only end up delaying it but could also blow up the overall cost. The only changes that should be made should only be as a result of damages that were not discovered during the inspection.

Consult Roofing Professionals

Even though you may have meticulously planned your roof replacement project, you need a professional to get the installation done right. Professional roofing contractors have the right equipment to ensure that your roof replacement project is completed on time. A roofing company will provide you with a detailed estimate after thoroughly inspecting your roof. They should also suggest roofing options that fit your budget, so be sure to discuss that early on.

Consider Roof Financing

In some cases, unforeseen roof replacement projects cannot wait. For instance, roofs that are heavily damaged by extreme weather need to be replaced immediately. In that case, you may need to consider roof financing.

If you’re thinking about replacing your tile and shingle roof, maybe steel roofing is something that crossed your mind. Your roof is, after all, the most important part of your home’s structure. It’s the covering which provides protection from the elements; which prevents water, wind and hurricane damage; and stops wild animals from entering your home. Steel roofing is a commonly perceived as a more durable roofing material. Below are three things to consider in re-roofing with steel as the main material


The cost to install a metal roof is inherently higher than the cost to install a traditional terracotta tile roof. This is because installing a metal roof is a more technical process involving a high level of skill, training, experience and expertise. Roof tiles are simply nailed to the roof deck – which is why there are so many horror stories about extreme weather conditions literally ripping asphalt shingles off the roof. Metal roofing, on the other hand, is only installed after premium breathable synthetic underlayment material has been laid down along with proper flashings and vents.

The price you can expect to pay for different types of metals and ‘profiles’ such as standing seams, steel shingles, metal tiles and stone-coated steel shingles is variable, but it is nearly always pricier than traditional roof tiles. Unfortunately, no one ever said that installing a steel roof was a steal. Many people point out that asphalt or terracotta shingles are the more economical choice.


The durability and longevity of a new metal roof are largely determined by its proper installation. It is critical not to try to cut corners by contracting an inexperienced roof plumber to complete the job.  A properly installed metal roof will last the lifetime on your home with little to no maintenance. Metal is pretty much the lightest material you can install on your roof, and it boasts good weather resistance as well as overall longevity. Many metal manufacturers offer limited warranties that last up to 50 years.

Overall, in terms of whether tiles or metal offers the best durability, it’s a clear win for metal. In addition to lasting for decades, steel won’t crack, peel, fade or disintegrate like roof tiles. Just make sure you choose the most experienced installer you can find to make sure they get the installation right first time.


Obviously, you want your roof to look good, and this is another important consideration when switching from roof tiles to a metal roof. Your roof is capable of adding a distinctive design element to your home as well as increasing its curb-side appeal so have a good hard think about what sort of aesthetic appeals to you. Design choices for roof tiles have come a long way since the 1970s. You can find clean, minimalist styles as well as high-end laminates enhanced with deep shadow lines and available in many colours.

The roof, like any other part of the house, requires regular maintenance to work at peak efficiency. Roof professionals often tell homeowners to avail of semi-annual inspections in order to fully utilise the roof and save up to 45 percent of the cost of a roof replacement and extend the life of your roof through corrective maintenance. Below are other ways on how roof maintenance can really help you save money.

Ensures Longevity

The roof’s ability to maintain a watertight seal against the elements is its’ primary job and when the roof can’t maintain a waterproof system, the longevity of the roofing system will be called into question. Don’t wait for your home insurer to tell you to commit a roof inspection, by then it might be too late to save the existing roof and a complete roof replacement may result due to negligence.

Damage Assessment

Twice-a-year inspections can identify damage that has occurred due to inclement weather, rodents or tree branches that breach the surface coating. When conducting a roof inspection some factors that you should consider would be the age of the roof, general wear and tear, damage and improper insulation to name a few.

Ensures Functional Roofing Elements

Inadequate insulation can cause heat build up in the attic that radiates through the roof structure to the shingles and in turn cause the shingles to curl and crack exposing the underside underlay to potential water leaks. Ventilation and insulation are the keys to protecting your shingles from the inside out. Most homes have asphalt shingles that coated in granules, over time and exposure, the granules become loose and wear off. When the granules start to decay it exposes the shingle surface and reduces their overall effectiveness.

Loose shingles or missing shingles is an indication that your shingle’s tar seal is starting to go, a temporary quick fix tar reseal will certainly help it is not a permanent solution to the problem. A roof that is buckling can trace the cause back to insufficient ventilation and attic insulation. Overheating creates moisture build-up that adversely affects the roof truss and roof decking that cause the roof to sag that is visible from the outside.

When conducting an inspection of any or all of these elements, it is important to determine if the elements are still in good shape. For example, is the vent still straight, if is not it might need to be replaced to prevent water damage.

Your water drainage system is another important element of a roofing system and its importance to your roofing system shouldn’t be underestimated. If you see that your rain gutters are blocked by debris, it can cause water build-up in rain gutters that cause two things to happen. Water leaks over the rain gutters and runs down the fascia putting the fascia at risk of water damage. The second problem is the added weight creates separation between the gutters and the building.
