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.
