There are many
types of roofing solutions and products available these days so
let’s look at a few. The IBR profile is one of the most commonly
used on roof sheets and is available in a thickness of 0.53 and
0.58mm. Aluminium, steel and galvanized roof sheets use this profile.
Although galvanized and steel roof sheet s are much cheaper than
aluminium sheets aluminium sheets do last much longer and doesn’t
lose its color as quickly neither.
Aluminium roof
sheets also known as Zincalume is much more durable than steel and
doesn’t need to be painted with a UV resistant paint like Silvacote
to protect it. All though Silvacote is a really great product you
still need to refurbish your roof sheets once every 5-7 years. Silvacote
does however protect sheets from becoming really hot and you can
also use it on waterproofing membranes to protect them against UV
rays.
Colorbond which
is Zincalume’ color roof sheet range has a special paint that
gets sprayed onto the roof sheet. Colorbond roof sheets last up
to 25 years before the color starts looking ugly faded and all sheets
fade the same amount. Zincalume is a great product with attributes
in it that gives the aluminium a life span of between 20 and 30
years. This was test in a open area next to the ocean in an marine
environment. Although Zincalume has a aluminium color the Colorbond
comes in many deferent shades and finishes. Zincalume and Colorbond
are both aluminium based. Unlike steel sheets that have a thickness
of 0.53mm and 0.58mm Zincalume is only available in a thickness
of 0.53mm.
Because Zincalume
is made up of aluminium roofing contractors need to use a certain
roof bolt to fix the roof sheet down with. One of the biggest mistakes
roofing contractors make is when they use cheap hammer in roof bolts
and doing things cheap doesn’t pay off in the long run. The
reason I’m so against those cheap roof nails is because they
always pull lose from the roof truss and your roof sheet either
ends up blowing off or water seeps in under it into your house.
The other biggie is that the self sealing washer which is suppose
to do its job leaks and has to be resealed with a Bitumen Plastic
tar paste.
The best roof
bolts on the market by a long mile are the Class 3 Self drillers
and just saying that name gives me Goosebumps. They are the best
and that’s just it, nothing more to say. The Class 3 Self drillers
has a small self sealing washer which you think won’t even
do the job but the deference is it’s made of rubber not plastic
so when it seals it seals.
Class 3 Self
drillers are also made to work with Zincalume roof sheets so neither
of the tow rust. If you are a roofing contractor or just a diy enthusiast
and would like to do your own roof I would strongly suggest you
use this product. It will simplify your life so much.
