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.
