One important building material to include in your construction: Jo Chivers

Whether you are building a single house, duplex or multi unit development, there is one essential building material that we always include. This item is not mandatory or compulsory in most cases, however Property Bloom has three good reasons why we include it. 

We are talking about sarking beneath a tiled roof. Sarking is a pliable membrane that sits under roof tiles, usually silver in colour. 

I've been watching as a new house is being built in my street.  As the roof was going on, I noticed they had not used sarking. The house is being built by one of the parents at my son's school who I know. So when I saw them next, I casually mentioned to them that I'd seen the roof had now been finished but there was no sarking. They said they had ummed and ahhed about it and decided not to spend the extra money on something no one is going to see. Big mistake I thought, but I didn't say that as it was too late for them to change their mind. Their bedrooms are all upstairs and the house faces west.  I know how hot it will get up there but that's not the only reason they should have considered it. 

So here's my reasons why we include sarking on our all Property Bloom developments:

1. Waterproofing. This is my number one reason. If you get a cracked roof tile, which is easy enough to occur in a big storm particularly if there are trees close by, sarking will assist in keeping out the moisture. Leaking roofs are your worst enemy. Once water seeps through the plasterboard, it can get expensive to repair and can also cause electrical damage. 

2. Insulation. This is a pretty good reason, particularly in a long, hot summer. We are seeing our temperatures rising and if you're sleeping just a few meters from your roof void, then chances are you are going to be hot or spend a lot of money on cooling this area. Sarking improves the thermal performance by up to 97%* and helps to provide a more energy efficient and comfortable home.

3. Dust. Sarking helps keep dust out of your roof void. If you have access into the roof void for storage or maybe thinking of creating an attic room, then minimising dust is a good thing. Also, if you have down lights or sky lights in your ceiling and no sarking, you may find dust can filter down into the living area through any tiny gaps created by ceiling fittings.  

On a typical Property Bloom duplex project, our builder charges about $1,800-$2,000 more for sarking and to me this is a small price to pay to ensure you have the highest of quality roof protection for your property. The last thing we want is for our clients to experience complaints from tenants down the track that their roof is leaking. 

Sarking is compulsory in bushfire rated areas and provides compliance to BAL bush fire ember attack requirements. 

So don't scrimp on your roof, it'll be a good investment plus provide peace of mind.
