So let's look at the
deferent roofing solutions you get on the market. One of the most
commonly we roof sheets is the IBR profile. This profile is available
in steel sheets, galvanized sheet and aluminium roof sheets. Steel
sheet and galvanized IBR roof sheets are more cost effective than
aluminium sheets. Steel roof sheet aren't very durable when it comes
to the elements like wind, rain and sun so it needs to be painted
with a substrate called Silvacote. Silvacote is an ABE product that
is made of a aluminium liquid paste. This liquid once stirred becomes
a think silver mold that is then painted onto the steel roof sheet.
For roofing purposes this liquid is magical. It reflects the sun's
UV rays preventing the roof sheets from heating up too much and
melting the waterproofing membranes. Silvacote is also used on waterproofing
membranes itself for UV protection.
A roofing product that
I really like is the aluminium roof sheet called Zincalume or Colorbond.
Zincalume is a hybrid product that last 20-30 years longer than
any roof sheet on the market. Zincalume is available without any
color where Colorbond comes in a variety of colors but is also aluminuim
based. Unlike galvanized roof sheets that are 0.53mm and 0.58mm
think Zincalume roof sheets only has a thickness of 0.53mm. Unlike
painted roof sheets Colorbond sheets also doesn't lose its color
very quickly. Not only that there are no lines painted on the sheets
that are formed from a paintbrush. This is because Colorbond roof
sheets are sprayed in a factory when manufactured.
When fixing roof sheets
to roof trusses the right kind of roof bolt needs to be used with
the appropriate roof sheet. Most roofing contractors just use the
regular roof nail that can just be hammered in. The problem with
those roof nails is that they eventually pull loose from all the
weathering like you would pull out a nail and the roof bolt washers
start to crack and leak too. Class 3 Self drillers are the best
to use when fixing down roof sheets and they also don't rust. Class
three roof bolts are perfect for Zincalume roof sheets as they complement
one another. If you use a normal steel roof bolt to fix down a Zincalume
roof sheet and it starts to rust the Zincalume sheet will sacrifice
itself on the spot where the roof bolt is rusting to prevent the
rust from spreading quickly.
This will put allot of
strain on the roof sheet and eventually burn a corroded hole in
the roof sheet. If you are roofing contractor or would like to replace
your own roof I recommend you use Zincalume. While it cost a bit
more it will save you allot of hassles in the future.
