The roof of your building is vital to its overall structure since it protects the interior and exterior of the building from any damaging substances. Your roof can also prevent any wear and tear from everyday exposure to sunlight and any type of precipitation. So, if you experience some roof problems, there is a high chance that it can go deep and weakens your whole structural integrity. 

One of the most common contributors to roof problems is defective flashing. Roof flashings, as a whole, protect your roof’s joints and angles from any source of water. They prevent entrapment and leakage of water towards the interior of your building. Without flashings, water can get past your roof and reach your ceilings and walls. Once they reach these areas, deterioration, and moulding over the surfaces will certainly follow.  

Poor roof flashings can also cause leaking problems among other problems on your roof. To guide you, here are some problems that poor roof flashing can cause your beloved building.


Poor installation and maintenance of roof flashings can lead to weakened roof’s membrane. This weakened roof’s membrane then leads to the billowing of roofs. Billowing occurs when large portions of the roof’s membrane detach and flutter with strong winds. As a remedy, a roofing professional must cut some parts of the membrane to release pressure on your roof preventing more damage to the rest of the membrane. This fix, however, does not prevent water and other debris from going into the building.

Blow Offs

Just like a billow, poor roof flashings condition can lead to open seams and joints of your roof. As time goes by, these openings can eventually lead to blow-offs of a part or of the entire roof when high winds or rains occur. One contributing factor to these blow offs is the reduced puncture resistance to a roof’s membrane. Reduced resistance makes the membrane of your roof separate itself from the roof’s substrate, thus, resulting in blow offs. This reduced resistance came from the usage of cold adhesives that aren’t cured long enough. 


When there is a dimensional change in the roof’s membrane, then your roof may shrink. This phenomenon is known as tenting or bridging. The dimensional change in the roof’s membrane adds pressure to the flashing and the roof seams, which can cause rupture afterward. The effect of tenting is irreversible; meaning, it should be addressed right away before water enters the building. The water can cause dry spots beneath the flashing or penetration of the roof. The tented areas must be cut by professionals and must be replaced with new ones immediately. When you ignored poor roof flashing problems, they can certainly cost you a lot when it comes to repairs and replacements. Strong weather disturbances can occur at a certain point, so if your weather permits, check for some roof flashing problems now. If you want to get help regarding roof flashing, Johnson Roofing got you covered. We are a licensed building practitioner that can help you with your roof flashing maintenance.

Construction firms know how to build the most ideal design and structure for your desired property. Be it a house or a commercial building, your construction firm will readily build whatever is agreed upon between the two of you. As soon as the building is turned over to you, it is now your responsibility to maintain whatever is built for you. Some firms may offer extended post-construction services, but others won’t offer you that kind of service.

And if some parts of your building start to wear off, there is nowhere to go but to hire individual services. For example, if your sewage system cannot store enough waste anymore and is close to leaking unwanted substances, then you should hire a plumbing service. Another example is that if your roofing cannot hold the rainwater, or it is getting too hot inside your home, then you should hire a company with roofing services.

Roofing Services for Hire

One of the most important parts of our property is its roof. Just imagine a house or building without a roof, it would take at least several minutes before various creatures and insects go in our properties. Different airborne particles like dirt, dust, and smoke may enter our premises in no time, which can be harmful to all of us. A building without a roof cannot even protect us from intense sunlight and strong rain, snow, and wind. 

The illustration above goes to show how important roofing can be in a building. Leaks and other health hazards can dominate the people occupying the building’s space. Thankfully, companies that perform roofing services can help property owners feel secured within the vicinity of their homes or offices.

A commercial building can benefit a lot with the right design and materials. Facades, walls, and other parts of the building might be able to create an impression of the whole building. However, a building’s roof tells a lot to the people inside the building.

Even if roofs are not that visible from the ground level, this specific part of the building can determine the overall structure of the building. In particular, the insulation of the roof can change the way a building holds into the integrity of its composition. This insulation can also affect the energy consumption of the building in a huge way.

Roofing insulation is essential to every commercial building since it produces the following outcome:

Serves Like a Protective Blanket

The roof surface and roof deck of a building have a layer in between that uses different materials for roofing insulation. These insulation materials include polyisocyanurate, extruded polystyrene, expanded polystyrene, mineral wool, spray foam, and fibreglass. With these materials, your roof can reduce the transfer of heat in and outside the building. On hotter days, your roof insulation will trap heat so that you won’t feel the direct outside temperature. Alternatively, your roof insulation will reduce heat loss during the cold season, which is a good thing for the entire building.

Prevents Growth of Moulds

Another great thing about roof insulation is that it prevents moulds from forming in the roof and even other parts of the building. They cannot survive the temperature and moisture of a building with roof insulations. However, there are cases that moulds still grow on the roof, but the layer of the insulation is thick enough to block the moulds from entering the surfaces that are visible to the building occupants.

Saves Energy and Electricity Bills

Since roofing insulation regulates the temperature of the building, some equipment and machinery are not required to run regularly basis anymore. Buildings where the roof insulation can effectively manage the heat distribution of the whole structure can save a lot of energy from the frequently equipment that used to maintain temperature. Moreover, the efficiency of the roofing insulation can hugely cut the electricity bills of business owners.

Lessens Carbon Footprint

Most buildings in Australia are built with careful consideration and elegant architecture. Moreover, property owners construct buildings that follow simple yet sustainable guidelines for a more safe and thriving environment. The installation of roof insulation can lessen carbon footprint that combats air pollution. With occupants reducing the use of electricity in general, their carbon footprint is now lessened for every occupant that works on a commercial building with roof insulation. This factor attracts business owners in leasing a commercial building since they want to comply with the ethical standards of a working environment.

Roof insulation can help your commercial building in a lot of ways. If you want to install one, then reach us at Johnson Roofing. We are licensed and highly regarded in doing roof works for any type of buildings in Australia.

As more and more countries are beginning to appreciate the wonders of renewable energy, different companies and households are now switching from coal energy to solar energy. Using such energy as a source of electricity is a good thing not just for the consumer, but also for the environment. Households that go green enjoy cheaper electricity, and at the same time, avoid the use of non-renewable energy like coal and petroleum as their primary source of fuel and power.

Many houses and buildings have adopted the use of solar energy at the expense of buying and installing solar panels on top of their roofs since the solar waves have almost no obstructions out there. However, you may want to hold your plans of buying solar panels and consider first the best roofing material suitable for your existing house or building.


Tiles are made of different strong materials that can last for a very long time, which made them the most common roofing material in Australia. As common as they seem, installing solar panels to them may take some thorough work. The solar panel installation with tiles includes the temporary removal of tiles, drilling of steel mounting brackets to the rafters, cutting some tiles, and reattachment of tiles.


When it comes to solar panel installation, metal roofing is considered the best type of roofing material. This is because the installation requires minimal work and zero drillings into the roof structure. Unlike tiles, metal roofing has roof screws that can be reused for the attachment of solar panels. This type of roofing material can certainly speed up the installation process of solar panels and cut down cost.


Another roofing material that can save a lot of time and workload in installing solar panels is composite. By just sliding the footings under the composite shingles, they can easily be secured to the rafters to which the solar panels can be attached afterward. They can withstand the weight of solar panels since they are durable and flexible, all at a cheap cost.

Tar and Gravel Roof

Homes with flat roofs often resort to using tar and gravel roofing material. This kind of roofing entails the use of hot tar, roofing felt, and some mineral coatings on its sheet layers. Incorporating solar panels to this kind of roofing requires additional brackets that can be tilted at a certain degree to catch sun waves. Although the installation procedure is easy, the cost of the tilted brackets and braces may be expensive. Still got questions about the best roofing material for your solar panels? Johnson Roofing can help you with that. We have done new roofing services to a lot of households in Australia and continuously serve more and more clients. Take note, installing solar panels does not translate to new roofs. Sometimes, you just have to re-roof to save you a lot of time and money. Luckily, we also offer re-roofing and roof maintenance.

A leaking roof can cause you and your family a variety of serious problems. A roof may begin leaking for different reasons, including poor installation, damage from harsh weather conditions and negligent upkeep. Even a small leak can lead to a series of home structural, health and safety hazards, from the attic down through your home’s foundation. Most roofs are predicted to last for 20 to 30 years if well maintained and repaired when needed. Why not take good care of your roof so that you can enjoy its protection and attractive curb appeal throughout those full 20 to 30 years? 

Major Unexpected Dangers that Your Leaky Roof Can Cause

Some major unexpected problems and dangers that your leaking roof can cause for you and your household include the following: 

• Attic and Upper Floor Ceiling Damage. The first sign of harm that a leak in your roof may cause is water damage to your home’s attic and items you have stored there. If the leak is extensive, or if your home has no attic, the ceiling interior of your top floor will be damaged. Plaster may begin to bubble and swell as ceiling paint darkens and stains. The adjoining walls will also suffer water damage, along with any ceiling lighting or fans. 

• Mold and Mildew Development.
If mold and mildew develop as a result of a leak in your roof, your home’s entire structure can be affected. Mold can also invade the HVAC system, including the vents. Eventually, mold and mildew may be present on your rugs, furniture, and personal belongings. The most common type of mold caused by water leaks is black mold. The non-toxic variety can weaken wooden framing, wall and floor surfaces or coverings and ceiling tiles. Toxic black mold can cause health hazards like lasting nasal congestion and asthma.

• Weakened Home Structure. Over time, a leaking roof can cause damage to ceiling joists, rafters, beams, wall framing or fascia boards. Serious and chronic water leakage through your roof can result in rotting roof framing that must be repaired or replaced by roofing contractors. When neglected, continuous water leaks from the roof can cause damage to the entire structure and interior of your home, which can be extremely costly to recover from.

• Fire Hazard. Serious leaks can also short out electrical wiring in ceilings and walls. If you detect a leak in your roof near ceiling or wall wiring, you should turn off the electricity in these areas until an electrician can examine the affected wires.

When you contact the experts at Johnson Roofing located in Albany, Auckland, NZ, you will receive top-quality essential information, advice, a roof inspection and all necessary repair or replacement services to restore your leaky roof.

When your roof requires maintenance to keep it in a functional, attractive condition, you must choose the right time of the year to perform it. In most parts of this country, spring is considered the ideal time for any roof maintenance project. Below, we share with you some reasons why you need to schedule roofing tasks during this time of the year to better illustrate our point.

Temperatures Are Pleasant

Spring temperatures are pleasant enough for the roofers to work without issue. This means fewer delays, especially for complex roof maintenance, such as re-roofing or installing new roofs.

Roofing Companies Are More Available in the Spring

Most roofing companies are not in high demand during the spring since property owners have different plans in mind for the time and money at this time of the year. As a result, you can schedule your maintenance easily when it is convenient for you without needing to wait. Choose another time of the year, and you may need to wait months to receive roofing maintenance.

Roof Maintenance Is Less Expensive in the Spring

Since the roofing companies are not as busy in the spring as they are at other times of the year, they are more likely to cut you an affordable deal on your roofing needs. Certain repairs and replacements for roofs that are a part of maintenance can be quite pricey during the busy season. You can use the savings on other home or building improvements if you require them.

Prepares the Roof for the Rest of the Year

Another reason that the spring is the perfect time for a roofing maintenance project is that you can prepare your roof for the rest of the year. After all, you might have a vacation planned for the summer and then, autumn and winter bring numerous holiday festivities with them. The last thing you want to do during those seasons is to have roofing tasks performed on your house, so hire the roofing companies in the spring and free up the rest of the year for more enjoyable plans, projects and even trips. In the event, that your structure is a commercial one, you may have many business projects coming up in the months ahead that you need your building ready for to ensure no issues happen.

For further information about why the spring season is the right time of year for roofing maintenance, consult with Johnson Roofing. Our company performs a full line of roofing services from simple maintenance and repairs to complex roof replacements.

You want everything in and around your home to work properly. This includes your roof gutters and drain pipes. Excessive water pooling in these locations means there is a problem that requires the attention of a professional roof maintenance service.

Possible Causes

Water pooling in your roof gutter could be a sign that the gutter is not draining properly because it is clogged. Water pooling in a gutter could also be caused by a damaged gutter. If water pools in a drain pipe, it may be blocked. A professional roof maintenance service can determine what the problem is if water is pooling in a gutter or pipe.

Damage from Water Pooling

If there is too much water in your gutters, they will overflow. The overflow will spill to the ground and could pool around the foundation of your home. The pooling water could cause mould or cause cracks to develop in the foundation. This could lead to structural damage. If water pools under the house, it could lead to damp floors. Excess water in pipes or gutters can also penetrate into your roof, walls and ceilings. If too much water penetrates, internal roofing may collapse. A blocked drain pipe can cause water to back up and flow over the flashing on the roof. The water may then leak through the roof on to your ceilings and walls. A professional roofing service will be able to fix your gutters or drains before serious problems occur.


A professional roofing service will know how to solve the water pooling problem. The most costly solution is to replace the gutter or drain pipe. However, that is not always necessary. If the gutter is clogged, cleaning it thoroughly will allow water to move through it properly. A damaged gutter will need to be replaced. If a portion of the gutter is damaged, only that portion will need to be replaced. Cleaning a blocked drain pipe may eliminate water pooling. If the pipe is too old, you may need to have it replaced. If you have your gutters and pipes regularly cleaned by a professional service, it is likely that you can avoid water pooling in your gutters and drain pipes.

Contact Johnson Roofing if you notice excessive water in your gutters or drain pipes. Our experienced team will find what is causing the problem and make the necessary repairs to fix the problem permanently.

Your home is one of the biggest purchases you will ever make. Making sure that everything inside and outside of the house is in good condition before you move in is important. An old house may have an old roof, and you will want to make sure the old roof has no roofing issues. There are some types of roofing problems you should be aware of when you are looking at old houses.

Improper Drainage and Leaks

You can detect water leaks by looking for stains on the outside and underside of the roof. Stains on the outside of the roof could mean that water is not being drained off the roof properly. This could be caused by clogged gutters. You should check to see if the house’s gutters are clogged with leaves or other debris.

If you see stains on the underside of the roof, the roof is leaking. You may not be able to see these unless the house has an attic or water is seeping into the ceilings.

Missing Roof Tiles

If the house has missing roof tiles, this could be a sign of old or damaged gutters. Damaged gutters can cause water to stay on the roof instead of draining into the gutters. If water remains on the roof, it can trickle under the roof tiles. This may cause the tiles to fall off the roof. Falling tiles can be dangerous to anyone who is near the house. If you see broken tiles on the ground near the house, this can be a sign of a roof damaged by water due to gutters that are not working properly. Gutters on an old house may be old and need to be replaced. You can check the gutters to see if they look damaged.

Tiles or Shingles are Not Aligned

Tiles or shingles on the roof should look straight and even when you look at them. If you see roofing material that looks uneven or misaligned, this means that the roof was not constructed properly. Misaligned roof material looks unsightly. It also means that the roof may not be completely waterproof. Water can seep through cracks or gaps that are created by the uneven placement of shingles or tiles.

Get in touch with Johnson Roofing if you notice some issues with your roof. We will be happy to work with you to make sure your old house has a roof without problems.

The upkeep of gutters and downpipes on the roofs of homes is a constant and essential concern for homeowners today. In order to ensure ongoing roof protection and the good working condition of your gutters and connected pipes, it is essential to schedule regular periodic inspections of your home’s roof areas and gutter systems throughout the year.

Only by engaging experienced experts in the professional roofing and gutter systems installation, maintenance and repair industries can you be assured that your home, its roof and gutter systems are damage-free and clear of tree branch twigs, dried leaves and other debris that can clog gutters and pipes, causing hazardous water buildups that can result in serious damage to your roof and gutter systems. 

Ways in Which Old and Damaged Gutters and Downpipes Can Affect a Newly Installed Roof

If your home’s gutters and downpipes are worn-out or damaged, they can seriously affect your newly installed roofing in the following ways:

• Water Pooling Damage. Excessive pooling of water on areas of your roof can occur when gutters and drain pipes become clogged with debris and cannot drain accumulated water from your roof during and after heavy rain or snowstorms. This pooled water can result in water leaks beneath roofing materials, damaging the underlying roof structure. This excess water can also leak into the ceiling of your home’s attic or top floor, causing damage to the interiors of your rooms. 

• Moulding or Rotting of Roofing Materials.
When water accumulations cannot drain from your home’s roof areas, roofing materials can become saturated and begin to develop mould and mildew. If left unattended over time, these water-soaked sections of your roof can weaken and rot, deteriorating to expose the supporting under-structure of the roof. Mould is a fungus that grows and spreads rapidly in damp or wet conditions, and this spreading mould will eventually cause irreparable damage to large sections of your roof. This may require the costly installation of an entire new roof on your home. 

• Dislodged Roof Tiles. Especially if you live in a very mild climate where attractive terracotta tiles are commonly used for roofing, you will enjoy the advantage of the adaptability of these clay-based tiles to absorbing water without being damaged and to dry out rather quickly under sunny skies. However, if your gutters and downspouts become clogged or damaged and water collects on the roof, seeping beneath the tiles, these tiles can become dislodged and fall from your roof, cracking and breaking while creating a hazard to anyone walking or standing near your home.  

By contacting our roofing installation and repairs experts at Johnson Roofing located in Albany, Auckland, NZ, and serving all surrounding regions, you can obtain top-rated inspections and maintenance for your home’s roof, gutters and downpiping. Our experienced professionals are prepared to install new roofing, repair damaged roofs and provide regular upkeep services to ensure that you always enjoy a safe, attractive and protective home roof with well-maintained and working gutters, drains, downspouts and connected piping. 

While you may be familiar with other roofing materials, you might not be with flashing. It is crucial to the integrity of your roof since it reinforces joints, valleys, walls, chimney areas and edges to prevent leaks. Flashing installs in an overlapping fashion that guarantees water cannot be trapped. Various materials are available for use as flashing. The one that is right for your house depends upon your budget, durability needed, how visible it will be and the other materials that the flashing will come in contact with on your roof. We discuss some of the best materials for flashing in the following.


Aluminium is a durable, versatile material and is suitable for numerous flashing locations, including in the valleys, around the chimney and at the walls or step-up areas. It comes in pre-formed shapes, sheets and rolls, so it can be customised when necessary. One advantage of aluminium is that it is a moderately priced material for flashing. Other benefits are that it is mouldable around corners or to conform to various angles and it holds its shape effectively. A downside to this material is that the uncoated version of it should not come into direct contact with mortar and cement since their alkalinity will corrode this material. In these situations, only coated aluminium should be used.


For a pricier, highly durable flashing option, turn to copper. It is resilient in all situations, including valley flashing with tile, chimney flashing, wall intersections, ridge areas and more. Copper can be fabricated into continuous, rigid custom shapes when needed. Flashing in this metal also comes in a lead-coated option as well, and this style is ideal for marine areas. With correct installation, it will last for years. Installation is easy due to the fact that it is a moderately pliant metal.

Stainless Steel

Stainless steel is an extremely resilient flashing material and is suitable for the harshest of environments. The price of it is comparable to copper flashing, placing it in the premium category of materials for this use. Typically, it is installed for base flashing, counter flashing and valley flashing. It comes in sheet form in both 18 and 24 gauges. One major advantage of stainless steel is that it is the flashing material that is least affected by salt spray, acid rain or other environmental corrosives. Also, it can be placed right against mortar and concrete since the alkalinity of these elements will not negatively affect it. A disadvantage of this material for flashing is that it is labour-intensive to install, which increases its already expensive cost.
