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.
