Drilling holes before installing the corrugated plastic roofing sheets will make the installation process easier and quicker.
You have to place the fastenings at a high portion of every fourth corrugation. The holes should be about two millimeters wide, with a diameter of about ten millimeters.
The holes should be bigger than the fastenings you are using to allow the roof to expand as heat is exposed to it. Use a hole-drilled stick as a reference when drilling the holes, which will be the roof base.

Place the ladder against a sturdy wall in your home so you can climb up safely to the roof. Get someone to help you hold the ladder steady to prohibit any accident from occurring.
Below the heads of the corrugated roofing sheets, there are waterproof seals that prevent leaks. Instead of using regular screws, use specialized roofing fastenings to secure the sheets.
Use silicone sealant when adjoining the sheets beside the vertical length. Make sure to overlap them with each other after the third wave crest.
Then apply a sealant to cover any gaps so that no possible leaks will happen.
To enable an appealing finish and an additional layer of protection, attach flashing. It will prove to be practicable when heavy rain arrives or if your roof links up to another housing structure.
