What’s On The Roof?

A METAL ROOF

This covers zincalume, galvanised steel and colorbond. Following are a few thoughts:

  • In general a metal roof is noisier as you can hear the rain (which I like)
  • They are fairly light so they don’t put as much load on the structure.
  • With modern screw fittings they can be extremely resistant to very high winds and hail.
  • Might get dented but will still be weatherproof in extreme hailstorms.
  • Less likely to leak.
  • Can be laid at lower pitch Which means the roof isn’t as high.
  • They are capable of lasting over a 100 years with minimal rusting.
  • Available in zinc finish or a wide range of colorbond colours. Zinc finish will be best for reflecting heat, followed by lighter colorbond colours.
  • Can be more expensive than tiles.
  • Fitting solar panels will be cheaper and easier on a steel roof.

One drawback is that you will need an external TV aerial and mobile phone coverage may be worse than under a tiled roof.

Tiles

Can be clay, terracotta or concrete. Their characteristics are:

  • Concrete has lower initial cost although some clay tiles and terracotta tiles can be very expensive.
  • Provide better insulation both heat and noise.
  • Heavier.
  • Brittle.
  • Need to be individually screwed down in high wind areas.
  • Wide range of colours.
  • Can add character especially as they age.

I have previously had a steel roof but now have tiles.

If building again I would probably go for metal.

Do you like the sound of rain on the roof?

Upstairs and Downstairs

In my first 35 years living in England I always lived in 2 storey homes.

I was never that keen on stairs for the following reasons:

    • During that time I thought that the worst job around the house, when helping my mother, and later my wife, was cleaning the stairs!
    • When we had young children there was always the worry about them falling downstairs.
    • If you got a leg injury you could be forced to stay on the ground floor until you recovered.
    • As you got older, if you didn’t want too move, you might need to buy a stair lift.
    • Moving new furniture is also a problem with 2 storey houses particularly when the stairs have a bend in them. . .The ones that double back are the worst!

Most people in Britain aspired to living in a single storey house, or as they call them in England ‘a Bungalow’.

Imagine my surprise when we moved to Australia and found that two storey houses were seen as the premium end of the market. I quickly said there was no way I would be living in a 2 storey house again.

Changing Circumstances

If I was a first time buyer with the current problems of urban sprawl and housing affordability I might be forced to think differently.

Perhaps the developers and builders also need to think again and start offering designs and subdivisions that are aimed at smaller two storey houses.

You do see a few smaller houses but they tend to be in body corporate infill developments as these are generally built closer to the city there isn’t the same saving for the first time buyer compared with newer subdivisions.

There are also often issues of limited parking.

 

Would you be happy to get a start in the housing market by buying a smaller 2 storey house, and then moving up to a larger two storey house as your family grow?

House Style or Fashion Victim

Appearance is very much a matter of taste with different people liking different styles, there no right solution.

If I put up a picture of something as the way to go than more people would think I was wrong, than would think I was right.

But here are a couple  of thoughts:

  • Avoid being a fashion victim, by going for the latest builders style, which was designed with the aim of grabbing your attention…………… The ‘WOW’ factor……………. In a year or two the ‘WOW’ gimmick and fashion will have moved on. For example about 30 years ago in Australia there was a trend for white bricks, which looks really dated now.
  • Going for the Victorian look, which seems popular, but can be risky. . . One mistake I have seen is this big two storey Victorian mansion on a small block surrounded by single story modern houses. It looks more like a pub than a home.

I try and go for what you could call a timeless appearance but what’s that look like?

The best suggestion I can make is to walk round an estate near where you live that is around 20-30 years old.

Some of the houses you see will look very dated.

Other will look as though they could have been built a couple of years ago.

They won’t all look the same……………….. just timeless.

Take some photos of the ones you like to help you compare with other designs you come across.

Here are some things you should consider avoiding:

      • Too many different materials. Brick, render, stone, painted wood, stained wood, all on the same façade can look very messy.
      • Different sized windows. The human brain likes to see order and a range of different window heights and widths on the same wall looks confusing.
      • Too many decorative elements.
      • Garage dominating the house.
      • Anything with a structural appearance that looks obviously stuck on.
      • Roof out of proportion with house. Could be either too large or too small.
      • A front façade that doesn’t link in with rest of the house. Some really look as though they have been stuck on the front face, particularly when they stop at the corner rather that continuing to a natural break point.

 What trend do you think will mark a house as a Fashion Victim?

Timber or Steel Frame

The most common frame for the standard brick veneer house uses timber.

Steel frames however are becoming much more common. . . . So why should you choose one or the other?

Advantages of Timber

  • Well understood by builders;
  • Cheaper;
  • Easy to adapt or modify during construction or later;
  • Is a sustainable resource;
  • Better sound and heat insulation;
  • Easier to fix fittings into;
  • Lock away carbon.

Advantages of Steel

  • Cannot be attacked by termites or borers; (that doesn’t mean you don’t need termite protection as there will still be plenty of wood in door frames and cupboards etc);
  • Prefabricated frames are lighter than timber;
  • Steel doesn’t have to be treated with chemicals;
  • Doesn’t rot;
  • Doesn’t shrink warp or twist;
  • Doesn’t burn;

NB. Inside a building rust will not be a problem, but just in case most steel frames are galvanised.

All my houses up to now have had timber frames and I have been happy with the result so I would probably continue to use timber if I was getting someone else to erect it.

If I was planning to erect the frame myself I would probably go for steel for the weight saving.

Rendered Foam Walls

This addendum was added to an original Post from 2014 as there has been a lot of publicity recently (late February 2019) about foam panels and certification has been removed from certain types of panels.

A particular issue for apartment blocks has been related to high speed spread across the surface of the panels to other flats.

On a standard house the render should protect the insulation from external flames. (If flames penetrate the plasterboard, from the inside, it is likely that the occupants will either have already evacuated, or be dead before the insulation ignites) n

Nevertheless you should review whether the potential risks from foam panels are acceptable to you.

Original Article

Rendered Foam walls are becoming much more common, particularly in the upper floor of 2 storey homes. They offer a real advantage in situations where it would be difficult to provide adequate suppport for a heavy brick wall (For example when the upper floor needs to be set back from the ground floor)

If you are worried about strength you need to be aware that the real strength of the house is in the frame. (see: House Construction – The Frame)

Construction

  • The Foam boards, which are manufactured with an external mesh face, are fixed to the frame with special galvanised screws that incorporate spreader washers.
  • Joints are sealed with a polyurethane foam and have mesh jointing tape.
  • External corners are reinforced with metal strips.
  • A minimum of 5mm of  acrylic render  is applied, normally in a three layer system.

Polystyrene Foam

There are 2 different types of foam used in this construction method:

  • Expanded polystyrene( EPS) – Good thermal performance but limited impact resistance/structural strength.
  • Extruded polystyrene (XPS) – Similar thermal performance and looks similar  but the production method is different which results in increased impact resistance and structural strength. Higher cost

Insulation values for the various board thicknesses are:

  • 50mm    – R 1.2
  • 75mm    – R 1.8
  • 100mm – R 2.4

Final Thoughts

Although there are some advantages in this system it does require careful detailing and construction otherwise leakage can occur damaging your house.

The advantage of masonry on the lower part of the house is that it is less likely to be damaged by the bumps and bangs of daily life. Once the wall is above head height damage becomes less of an issue and the rendered foam board should be fine.

I’d prefer XPS to EPS.

Although the insulation values are good the builder will most likely want to save the cost of the insulation batts in the frame. If you ask for the wall to include insulation batts you will have an exceptionally well insulated wall at very little extra cost.

Will Your Roof Take Solar Panels?

Plenty of people are thinking about solar panels as they can save a lot of money.

But is your roof strong enough?

In the old days a house roof had a good factor of safety so they could take the additional weight of solar panels, or a solar hot water system easily.

These days it would seem some builders are cutting costs by using lighter trusses in the roof.

This means that the roof doesn’t have  the strength to take the weight of solar panels.

I have heard of new builders asking for $300, or more to upgrade the roof.

If you think you might want solar panels, and I suggest that it is a good idea, make sure you ask the builder if the roof is strong enough.

What are balustrades and why are they important for safety in your home?

Guest post by James Andrew

If you have invested in buying a property, you want it to look good and you want it to be a safe place.

The last thing you want to happen is for someone to get hurt while living in, or visiting, your home.

This is why you need to pay attention to aspects of your property that provide protection.

Once such aspect is the balustrades in your home.

The aim of this article is to explain what balustrades are and why you need to ensure that they are installed in your home, and well maintained.

What are balustrades?

The word balustrade sounds very grand; but balustrades are actually very common place, they consist of a series of posts or columns, topped by a rail.

You find them on staircases, platforms and terraces, including in your own home.

The foremost aim of a balustrade is to provide protection.

They can also form an important part of the interior décor of a property.

From a safety point of view if you do not have secure balustrades in place in your home, it’s easy for people to have accidents.

Looking at balustrades as a item of décor, it’s important that they fit within their surroundings.

Why are balustrades important?

We have already touched on the importance of balustrades for safety purposes; let’s look at this in

more detail.

Imagine someone is visiting your home.

You have a balustrade fitted to your raised terrace but it’s old and you do not pay much attention to it.

Your visitor leans on the balustrade, it gives way and they fall to the ground below.

Not only is the person likely to get hurt, you will feel guilty and could be sued by the injured party.

It’s not worth taking the chance when it comes to balustrades.

You need to ensure that they are good quality, securely fitted and well maintained.

If you want information about the fitting of balustrades, click here for more information.

The decorative aspect of a balustrade

We have established that balustrades are essential in your home.

This being the case, it’s important that you see them as an integral part of your décor.

If you do this well you can actually use them as an impressive feature that catches the eye.

Balustrades can be made from different materials, with the most popular being timber, metal and glass.

The material you choose will depend on how your home is decorated as well as your budget.

Do not forget that it’s also possible to have balustrades outside your property.

They can still be used to add to the overall visual appeal.

You also need to ensure that this type of balustrade is able to withstand varying weather conditions.

Now you know what balustrades are, and why they are so important.

Do not neglect the balustrades in your property.

Doing so could be dangerous and someone could end getting seriously hurt which is not something you want to happen in your home.

Floor Loadings

One of the things with blogging about houses is you can’t stop looking at buildings.

I was on holiday in Cairns a couple of weeks ago and looking out of my hotel saw this balcony.

What a great idea to have a Spa on the balcony! . . or is it?

That spa when full of water and with 4 adults could weigh in excess of 1,500kg (1.5 tonnes)

With the pumps running there could also be quite a bit of vibration.

I wonder what the building engineer thought of the idea?

Any Plans For Heavy Items?

Heavy items such as Spas, or even Pianos will be fine on a slab ground floor.

If however you want them on the first or second floor make sure the building engineer knows what your want.

Most structural frames should be able to take the load but you could get considerable deflection of the supporting beams.

Also

Something that is often forgotten is how you would get large and/or heavy items up stairs.

In one investment property I owned it was hard enough getting a double mattress up the stairs!

Identifying signs of termite infestation.

Guest Post by Hubert Dwight

One of the worst nightmares for homeowners is to find that their home is being attacked by termites.

The thought of termites terrorizing your home is enough to send shivers up your spine.

If you are already aware of the damage termites can do to your home, you have every right to have a sense of fear in knowing what extent damage from their presence can do.

If not, then buckle up as we inform you of what termites can do, how they can impact your lifestyle and offer you prevention tips to overcome these issues.

Prevention Is Better Than Cure.

Before going into detail about managing termite infestations, we recommend that you take as much action as possible, such as undergoing Termite Treatments to prevent any infestations.

The cost to resolve the impact from termites can be in the thousands  depending on the extent of the damage.

Below are a few ways you can prevent your home from being infested from termites.

Building Design

The way the building is designed can reduce the risk of infestation to the home. This includes:

  • Reducing the amount of timber that is used in buildings.
  • Using properly designed concrete slabs with edges exposed.
  • Installing a reticulated system under the concrete slab that allows chemical barriers to be applied and reapplied when necessary.
  • The use of physical barriers – Such as metal shields, stainless steel mesh or granite chip barriers can all be used to stop termites getting into buildings.
  • The use of chemical barriers (termiticides) can kill and remove termites through treated layers of soil under and around concrete slabs and pipes. These termiticides can kill or repel termites and even eliminate the entire colony should the termites take the termiticide back to the nest.

Detecting Termite Infestation.

Detecting a termite colony in or around your home indicates your house is at a serious risk.

The average size of a termite colony will range from 300,000 to over a million termites made up of swarmers, workers, and soldiers that can cause serious damage to your home.

While having thousands or millions of these little critters around your home is dangerous, the termite queen poses an even greater risk as she has the power to multiply the colony substantially as she can lay over one thousand eggs in a day.

These termite eggs don’t just go away after a short amount of time neither as they can survive for up to 50 years.

So even if you take actions to remove nests and infested areas, the queen still has the ability to repopulate the colony to its previous levels if the termite infestation isn’t completely dealt with.

Where Are Common Breeding Grounds For Termites?

Termites often breed in the ground and create tunnel systems in the soil.

The mud tubes that they make connect their colonies underground to food sources such as wood materials from your home.

Some termites also live in water sources such as damp areas or leaky faucets produced by rain.

They prefer to dwell in a place with moisture so they will be able to survive and populate.

Having termites in the house can be quite stressful. They can lead to increased safety and fire hazards within the home.

If things get really bad, they may even force you out of your home as they make their way through your dwelling, room after room, growing into a plague of biblical proportions and it can become a living hell for those people that have to live in it.

You must commit to taking action before it is too late.

You have learned that the way termites are, they keep coming and coming and coming, even if you have removed nests or done some baiting yourself, if the queen still lives or if there is a colonization that hasn’t been found, they can repopulate their lost colonization.

Avoid devastation and take action to identify and combat termite infestations as quickly as possible.

 

Roof Access Hatch – 5 Considerations

Guest post by Hubert Dwight

If you are considering building a house with a flat roof or very low pitched roof (2-5 degrees) perhaps you should think about a roof access hatch.

If you are thinking about installing a roof access hatch in your new home, here are some important things to consider:

Convenient Access

There are a lot of reasons why you might want to have convenient access to your roof .

You never know when you are going to need to get up there to do small repairs, install an aerial, clean the solar panels,  or just  retrieve your kids ball from the roof.

In fact, some people have  small gardens because of the shade free sunlight they get up there.

Whatever your reasons for installing a roof access hatch, having this convenient access is much easier and safer than having to get out the ladder and climb up the outside of your house.

NB If you plan on regularly accessing your roof you will need to address the issue of ‘Falls From Hight’ and take precautions such as high parapet walls or balustrades.

Safety

Having access to the roof in times of fire, flood, or other natural disasters can save your life.

For example in a bushfire situation it would make it easy to install sprinklers on the roof perimeter to provide a spray that would envelope the house.

In a flood the roof will be the safest place.

While these events don’t happen often, don’t let yourself get caught in a situation when you realise you should have had one installed for safety reasons.

Sustainable

Its a good idea to ask about the insulated options.

Openings facing the sky lose a lot more heat in winter than vertical openings. they also are subject to the most direct sunlight in the summer.

Now, while you might spend more money on the front end, down the road you will have minimised your energy consumption.

Access To The View

If you are a serious amateur astronomer or just a casual ‘stargazer’ you can get a much better view from above the streetlights.

A  view from the roof will also give you an unobstructed view of the New Year Fireworks!

Value

When you decide to invest in a roof access hatch quality is very important.

Our homes and properties are some of the biggest investments we can make in our lives so for a roof hatch value means quality more than price.

On the roof the hatch will have to withstand pouring rain and strong winds. . . In alpine areas there could be snow and ice in winter.

You should look for a supplier with well designed weather seals and strong construction to avoid warping.

Achieving a 5 star energy rating is also really important.

 

A roof hatch can have many benefits but make sure you choose quality.
