How Do You Maintain a Roof?—Tips from an Expert Roofer

Roof maintenance is no walk in the park. We all know that apart from the high cost it entails, it also comes with certain risks, especially if you are not a handyman. If you take into account the benefits you can get from regular roof inspection and maintenance, you’ll see that it outweighs the drawbacks. As for the risk, you can eliminate them by simply hiring a reputable roofing company like GMZ Roofing who can do the job excellently. They have the experience, skill, and proper tools to do the job safely and with zero damage to your property.

Benefits of Regular Roof Maintenance

Homeowners can’t be blamed for being reluctant to have their roof checked by a professional roofer every once in a while and updated if necessary. After all, roofing systems are made to last, and they usually do. It takes years before signs of wear and tear start to show up, and most homeowners only take action when it’s too late. The fact that roofs are difficult to access adds to the reasons they are often neglected. Here are some of the best benefits of regular roofing maintenance that all sceptical and neglectful homeowners need to know.

  • Keep Your Energy Bills Low – Your roof doesn’t just protect your home from the elements; it also insulates it from extreme outdoor temperatures. So if your roof is made of poor materials, not installed properly, or lack the required padding, more heat or cold can seep in, and that means extra work for your heating, ventilation, and air conditioning system.
  • Keep Mould and Vermin at Bay – Lack of maintenance allows small sources of leak, such as cracks or holes, to grow. As the leak increases, so as the water damage in the roof, and we know what happens next when we leave an area damp for some time—mould and mildew. Water also weakens materials it comes in contact with, making it easier for all kinds of wild animals to break into your attic.
  • Maintain or Increase Your Home’s Value – The roof is the first thing a potential buyer will see and it usually makes the first impression. A roof that looks dilapidated with missing shingles or moss growing on its surface isn’t particularly attractive to buyers. It’s easy to distinguish well-kept roofs in a neighbourhood chockfull of houses. Even if they are older than their surrounding roofs, they normally look cleaner and sturdier, everything a smart buyer looks for in a house.
  • Preserve Your Home’s Structural Integrity – Whenever your roof blocks and conveys rainwater down the sewer main, it also prevents some of your home’s major structural components from sustaining water damage, including the trusses that serve as the roof’s framework and the footing down below. Instead of directly pouring on the soil that holds the footing together, water flows through the gutter and is funnelled away through the drainage system.

Roof Maintenance Checklist

Many homeowners are easily discouraged to conduct maintenance on their roof because they think it involves a lot of repair work. Specifically, they don’t want their day-to-day activities disrupted, and that’s apart from the possible cost of the whole project. Maintenance is actually different from repair. In fact, the main reason you are maintaining your roof is because you want to avoid the need to do major repair. Besides, you cannot keep on avoiding repair forever, but you can avoid incurring large expenses if you perform maintenance. How do you maintain roof shingles then? Here’s a quick guide you can follow.

  • Know when maintenance should be done – Experts suggest that you maintain your roof at least twice a year, but when exactly? To know when to carry out the roof maintenance, take the seasons in your area into account. The last thing you want is to work on your roof on a windy or rainy day. You also need to prepare for occasional maintenance, particularly after a bad weather.
  • Conduct routine inspection and keep records – Inspect your roof from time to time even when the weather seems fine. Keep in mind that the weather isn’t the only enemy of your roof. Poor installation and low-quality materials may prove detrimental, too. If you conduct routine inspection and maintain records, you can tell how gradually your roof is failing and from there you can make a good prediction when the next maintenance, or even replacement, should take place.
  • Replace broken or missing shingles – When there’s a crack on any one of the shingles, it’s almost always impossible to fix. The best solution is to replace the damaged pieces. Make sure to do this right away because it may cause leak that can wreak havoc in your attic.
  • Inspect the flashing – One of the major causes of leak in your roof is broken or heavily corroded flashing. This is the metal plate that seals up the grooves and edges of the roofing system to prevent water from leaking through. While applying sealant may be helpful, it would still make for a leak-free home if broken flashing will be completely replaced.
  • Coat your metal roof – If you have a metal roof, it’s imperative to apply coating on it. Although majority of metal roofs are made from galvanised steel, they are still susceptible to corrosion when exposed to the elements for a long time. Coating will give them additional protection. If the paint is already fading away, consider recoating immediately.

You can avoid these dangerous yet critical tasks by simply hiring one of the reputable residential roofing contractors in Auckland, although these roof maintenance tips may also come in handy in their absence. With their experience, you can expect that any possible issue will be dealt with straight away and excellently. They also know the best materials to use if even you are planning to replace your roof soon, and they can do the installation as well.

Roof Repair and Maintenance Tips for Homeowners in Auckland

Prolong Your Roof’s Life with These Roof Repair and Maintenance Tips

Summer is almost over but Auckland and the rest of the country will still enjoy abundant sunshine in the coming months. This means you have an ample amount of time to inspect, repair, or update your roof. Whether you’ve owned your house for a while or just moved, you can greatly benefit from keeping roof repair and maintenance top of mind. You don’t want to worry yourself with these tasks in springtime when the weather can go berserk anytime.

Unlike house cleaning or car tune-up, however, roof inspection and maintenance isn’t a simple chore that any inexperienced households can pull off. It requires the expertise of a well-trained and highly experienced roofing company like GMZ Roofing. Rather than risk doing more harm than good to your roof, it’s better to put your roof in the hands of a company that knows what issues to look for, how to fix them, and where to get the best materials when repair or replacement becomes necessary.

Then again, while a roofer can help fix existing problems with your roof, they can only do so much. As to how your roof can last before you need professional help again, that part is all on you. Here are some roof maintenance tips that can help prolong the life of your roofing system.


Free Your Roof from Organic Debris

Roofs may be tough but they are not indestructible. Like other parts of your house that need regular cleaning to slow down deterioration, your roof needs regular cleaning, too, for the same reason. When you go up there, you’ll realise that ground dirt and dust are the least of your concern. The ones that really pose a threat to the health of your roof are leaves, twigs, and other organic debris. As they decay, they produce substances that might be harsh for the roofing material, or worse fungi and other destructive microorganisms may arise from them, spread across the roof, and cause even more serious problems. They can also get caught in the gutter and block the path of runoff.


Prune Troublesome Trees

To avoid problems with dead leaves and twigs, why not cut the source? Rarely can leaves and twigs from the neighbours get blown off and land on your roof. Most of them come from the trees and bushes around your own house, particularly from overhanging branches. Trim your trees so that no branches will touch or lie over your roof. Not only do these overhanging branches dump dead leaves and twigs on your roof but they can also land destructive blows when tottered by strong wind.



Your roof can get too hot during the day, especially in summer, and too cold during the night, especially in winter. Either circumstance, if neglected, can leave a trail of damage that could render your roof dysfunctional. For instance, moisture can develop on the decking’s underside, which could easily turn into a breeding ground for microorganisms. During winter, heat from the inside of your house may melt the ice build-up on the exterior surface of your roof and create an ice dam, which is notorious for causing severe water damage on the roof and in the attic. Installing a ventilation system can inhibit these problems.



While ventilation regulates the temperature by maintaining sufficient airflow underneath the roof, insulation keeps temperature from being transferred from and into the house. Specifically, it has two important jobs—to maintain your home’s energy efficiency by preventing heat gain/loss and to stop moisture from rising into the attic. It is the element that keeps your home comfortable during summer, winter, or a bad weather.


Fix Broken or Missing Shingles Immediately

Sandwiched by two seas, Auckland enjoys a fair share of high wind coming from every direction. This wind may range from mild to strong, and sometimes strong enough to blow off roof shingles. Especially during a storm, and your roof is poorly installed and maintained, expect to see pieces of shingles lying on your yard the following day. That could mean a great deal of trouble for your home. Before the next rain falls, you must have the damaged area of your roof patched or else you’ll have to deal with severe water damage.


Beware of Fungi and Algae

While fungi and algae may seem harmless, they are considered to be a serious problem or at least a sign of a serious problem when seen growing on rooftops. They may either indicate that there’s moisture build-up on the underside of the shingles or become the problem itself. These microorganisms grow where they have immediate food source. And if you’re curious as to how they feed, they actually consume decaying matters. They break them down by releasing some kind of enzyme. This enzyme may end up affecting your roof, too, so it is highly advisable to clean off algae or fungi growing on the surface of your roof before they could spread.


Coat If It’s Wood or Metal

Those who want a home that looks rustic and natural opt for wood shakes, while those who like a little bit of modern touch on their rooftop go with metal. Whichever of these choices you prefer, you should never forget to coat them after installation. The coating isn’t just for aesthetics but for the protection of your roof from the elements as well. Wood shakes especially need coating because they are an easy target for insects and wild animals. Coating metal roofing, on the other hand, both prevents rusting and makes the roof look hip or at least matching to the home’s overall architecture.

All of these tips can only do so much to stretch out the life of your roof. Soon you will encounter issues that you can no longer handle on your own. That’s the time you should call in a roofer to help you out. They can conduct a thorough inspection of your roof and tell you the best course of action.

You may think that hiring a professional roofer isn’t a practical choice, considering how much it could cost compared to DIY. However, if you look at how many years you can add to the life of your roof without every worrying out repair and replacement, it sure is worth it. Does insurance cover roof repair, you may ask. Check your coverage to identify cases in which insurance can be used. Overall, the benefits of having a professional check and fix your roof is too staggering to ignore.


Residential Roofing Contractors Identify Top Causes of Roof Leaks

Noticed water damage in your attic and ceiling? That’s probably caused by roof leak. Find a trusted roofing contractor to fix it right away.

Roof leak is a leading cause of water damage in New Zealand homes. In fact, a couple of decades ago, it was a widespread household problem that particularly affected untreated timber-framed “Mediterranean” style houses with flat roofs and plaster cladding, which was trendy at the time. The problem was so serious it was later called “The Leaky Homes Crisis”.  

Thankfully, with today’s leak-proof home designs becoming increasingly popular and improvements to the building code being strictly observed, the crisis has finally died down and affected families are coping. Then again, this doesn’t mean you can live a carefree life, as shifting to a modern home style doesn’t guarantee freedom from roof leak. After all, roof leaks may come from a variety of sources other than poor design, including the following.


Damaged Vents

Roof vents are made to prevent the transfer of heat and cool from inside and outside of your house. They consist of several parts, including pipes and gaskets. If any of these parts were broken, outside moisture or water can easily leak into the house. Make sure the pipes and gaskets are intact with no cracks, gaps, or even missing nails. If you discover issues, don’t hesitate to call in a roofer to fix them immediately.


Shallow Slope

Some homeowners opt for a low-pitched roof to save money, not knowing that reducing the pitch could affect the roof’s ability to resist leak. Although roofs can be made flat, a special technique is needed to achieve this without compromising leak tolerance. Residential roofing contractors understand that this technique can’t be used for other roofing materials, such as shingles and shakes. The minimum slope for asphalt shingles and wood shakes must be 2:12 to prevent water from backing up into the house.


Ice Dams

During winter, ice forms underneath the pile of snow on the surface of your roof. If your roof lacks proper ventilation, the heat from your home escaping into the attic may melt that ice. The snow cloaking the roof dams the snowmelt. Instead of falling into the gutter, the snowmelt will seep underneath the shingles and into the roof deck.


Poorly Installed or Broken Flashing

Roof edges as well as the sides of your chimney are notorious sources of leak. This is why they must be sealed off with flashing. The problem is that over time the flashing deteriorates, opening paths where water can trickle into the house. You have to make sure the flashings are properly sealed and resealed on a regular basis. In fact, if you’ve just moved to a new house, flashing in those areas are among the first things you should check.


Wobbly or Bent Ridge Cap

The peak of the roof where two of the roof’s edges meet is actually open. It is closed and sealed with a bent ridge cap. The cap’s position makes it the most vulnerable part of the roof because it can be easily blown off by high wind if not installed properly. Over time, its seal wears away and some nails might go missing. When this happens, the cap will become less resistant to wind force and as it wobbles, water may seep through its underside.


Debris Build-Up

Snow build-up is not the only cause of dams that wreak havoc in roofs. Debris such as twigs, leaves or pine needles can trap water on the roof as well and cause as much damage. Whether or not your house is surrounded with trees that might be the culprit to such occurrence in your roof, you have to stay alert and keep your roof free from debris at all times. Sometimes, these debris may even block the downspout, causing water to dam in the gutter and back up into the house.


Broken and Missing Shingles

Roof shingles’ single most important job is to guide rainwater or snowmelt into the gutter. If one of them has been damaged or worse blown off, nothing in the emptied zone will prevent water from trickling down into your house. Once water breaks into the roof deck, it will leave a trail of damage that’s difficult to repair. So it’s crucial to check the roof for broken or missing shingles every now and then, especially after a storm.

To ensure your safety, use the proper fall arrest when working on your roof. For guaranteed lasting solution to your roof leak problems, leave the job to a trusted commercial and residential roofing contractor, such as GMZ Roofing. Not only do they have the right skills for the job, but they also use advanced tools for detecting and fixing leak sources.




Roof Painting Services and Other Effective Ways to Maintain Your Metal Roofing

With so many roofing types available on the market, it’s so hard to choose the right one for your home. If you know what features you want, however, decision-making can be a breeze. For instance, if you are looking for longevity and flexibility, your best bet is a metal roof. Lighter than wood shakes and slate, metal roofs are easy to install and just as durable.

That said, metal roofs are tricky to maintain. Unlike tile and slate that require minimal upkeep, metal roofing has to be regularly checked to make sure no damage is shortening its life. Here are a few maintenance tips you can follow if you have a metal roof you want to last a lifetime.

Clean It Regularly

Regular cleaning is a necessary step in maintaining a roof regardless of its type, but metal roofing seems to need it more than the others. This is because dirt and debris, particularly the organic ones such as leaves and twigs, may cause the metal to corrode. Even if the metal used is non-ferrous or does not contain iron, it may still corrode. The trick is to eliminate any substance that can trigger corrosion and seal the surface of the roof.

Removing Rust

When you find patches of rust on the surface of your roof, clean it right away to prevent it from spreading and cutting through the panels or shingles. Do not use a steel brush to remove excess rust because too much pressure might poke a hole into severely rusted areas. Better scrub with a clean cloth dipped in a special metal cleanser instead.

Separate Different Metals

Metals are quite sensitive materials. Different metals don’t like coming into contact with each other. When they do, they often react by breaking down in a process called electrolytic corrosion. It’s dangerous when the metals in question are on your roof. The last thing you want is a streak of corrosion on your roof caused by a copper pipe laying on top of your galvanised steel roof.

Paint the Roof

One of the reasons why many households prefer metal roofing to other types of roof is that it can be painted in the colour or style they want. They can even paint it based on a certain occasion or even to match a newly installed siding. To achieve a fine roof painting, consider using professional roof painting services from premier roofing companies in Auckland like GMZ Roofing.

Paint improves not just your metal roof’s aesthetic appeal but more importantly its protection against the elements. Roof painting professionals are highly trained in coating all kinds of roof and use only the highest quality paint products. They know exactly the kind and brand of paint that could meet the highest roof coating standards.



5 Red Flags that You Need Re-Roofing Services Soon

Roofs are not made to last forever. They get old, deteriorate, and fall apart like everything else. It’s important to inspect your roof regularly to determine when to call a trusted roofing company like GMZ Roofing for repair, maintenance, or replacement. Don’t wait until leak starts wreaking havoc in your attic before you ring them up. Here are some revealing signs that you need re roofing services as soon as possible.

Shingles or tiles are firmly installed on the roof’s underlayment so they are not supposed to be easily removed or dismantled. If you found out that there are a couple of shingles missing, don’t ignore it not only because the empty slots may funnel rainwater into your house but also because it can be a sign of a more serious problem brewing above your head. Especially if your area wasn’t hit by a bad storm recently, it could indicate that the entire roof is starting to fall apart due to old age and something has to be done soon.

Rust in Metal Roofs

Many metal roofs are rusted that will, if left untreated, progress into holes and leaks. Badly rusted metal roofs may be past repairing and it may be more economical to re-roof.

Sags and Cave-Ins

Roofs need to maintain a flat, slanted surface to ensure runoff falls into the gutter and away from your home’s walls and footing. Any dip may cause water to pool and slowly seep through gaps, causing serious damage to the underlying structure. If neglected, water can make its way into the attic and down to your ceiling. Most cases of sagging on the roof are beyond repair because the underlying structure is no longer structurally reliable in which case replacement is the only viable option.

Severe Damage

When was the last time you had a roofer inspect your roof? If it’s been more than a few years, chances are your roof is already seriously worn. Don’t be surprised to see rust, cracks, punctures, holes, and splits all over the place. Assess the state of the roof right away and determine if the damage can still be repaired. If you find damage across the roof instead of just in certain areas, then replacement is the best course of action.

Granules in the Gutter

The granules accumulating in your gutter come from the asphalt shingles. These are pulverized minerals that comprise the top layer of the shingles. Over time, as the shingles get exposed to the elements, this layer of minerals dislodge. They then get flushed to the gutter by runoff. Losing granules exposes less resistant layers of the shingles, which could lead to complete damage of your roof.

Replacing your roof is a big decision, considering the huge budget it entails. However, if all the signs show that it is the best course of action, don’t stall and resort to fixing problems as they emerge. It might surprise you to know that you can actually save more when you install a new roof than when you keep fixing damage.

That said, there are certain considerations you need to make for a successful roof installation. You should learn more about “reroof vs new roof”, for instance. A professional roofer from GMZ Roofing can help figure out which is better for your situation. If you opt for reroofing, find out how much to reroof a house, although that would certainly cost less than constructing a roof from scratch.
