Polycarbonate Roofing Installation
Polycarbonate sheets can be used as walls or as roofs.
These roofing sheets come in variety of color, profile and sizes. The price of these sheets varies immensely
depending on the profile. The most common profile is a corrugate plastic roofing sheet.
The guarantee, which comes along with these sheets, may range from a few months to lifetime
depending on the quality of these sheets. But a key aspect is the ease of installation.
Polycarbonate Roofing Installation Tips
Please consider the following points prior to installing your polycarbonate
Most of the manufactures of polycarbonate sheets advise an approximate fall
of 1 in 5.7 i.e. a 10 degree pitch. You will need extra shielding from weathering elements if you
take a sheet of less pitch.
Most of these sheets can be cut with the help of a fine tooth saw or garden
scissors. The better of the quality of these sheets, the easier it is to cut them. If you want to
cut a sheet at a time, you can even use a disk grinder or carborundum. The only disadvantage is
that cutting more than one sheet at a time can lead to fusion and welding of sheets. Find out more
Before you fix the sheets, drill the holes. The adequate size of the holes is
almost 8- 10mm. The holes should be a little larger than the screw's shaft (at least 2mm) so that
there is enough space for the screws to expand and contract. For more details, you can refer to the
guide that comes along with the roofing sheets.
You can get appropriate screws from the manufactures of polycarbonate roofing
panels. The easiest to use are the one with hexagonal heads. Most sheets are needed to be fixed at
every fourth corrugation.
You can even use some other accessories like foam eave fillers or ridge/apron
flashing with the polycarbonate roofing sheet. These are available with the suppliers of roofing
When installing these types of roofing materials, here are 4 things you should
1) Make sure that you install them on a slope
of at least 1 inch for every foot they are long. This will ensure proper drainage.
2) Before installing the screws, it is a good
idea to pre-drill the holes in the polycarbonate. Doing this will keep the shingles from cracking and will save you
a couple of them. You may also want to use a washer to hold the screws in place and keep them from tearing
3) When installing side by side panels. Make
sure to overlap. You also want to caulk the seems to prevent water from getting trapped in between the shingles.
Start at the bottom and then work towards the top so that the shingles can overlap on the way down.
4) Be careful not to walk on the polycarbonate
roofing material. It may look safe enough, but a roof of this type isn't designed to take your weight. For this
reason, it may be a good idea also to regularly clean it off if you have heavy pin needles fall on it or if you get
more than 6 inches of snow.
