Decide to use Gable or Wall Flashing
There are two main choices here on this first point:
- If the side of your roof is not up against a wall then you would want to use a gable wall flashing. The best gable flashing option is the Corrapol®-BT Rock n Lock Gable Flashing which is available in Black, Brown, Green or Red, if you are installing Corrapol®-BT corrugated bitumen sheets, or alternatively choose the White or Mill Finish colour options for Corrapol® Corrugated Polycarbonate Roofing sheets.
- If the side of your roof is up against a rising wall then you will need a wall flashing. Corrapol®-BT Rock n Lock Wall Flashing is available in four matching colours, or choose White or Mill Finish colour options if you are installing Corrapol® Corrugated Polycarbonate Roofing sheets.
Buy top wall flashing to save time
One of the hardest areas to seal on a corrugated lean-to roof is where the corrugated roof meets the back wall, where there’s no flat surface for lead flashing to seal on to. Top wall flashing makes corrugated roof flashing 75% easier to waterproof. Corrapol® Top Wall Flashing for Corrapol® Corrugated Polycarbonate Roofing sheets comes in white or mill finish, with options of 2m, 3m or 6m sizes.
If you are installing corrugated bitumen sheets then choose Corrapol®-BT Top Wall Flashing in Green, Black Brown, or red colour options. These aluminium corrugated roof flashings can be cut and mitre for almost any roof angle.
Check Ridge options and endcaps
For all apex roofs you should use a quality ridge solution, as the ridge is where the elements hit hardest. An aluminium ridge is a vitally important corrugated roof flashing, making the ridge connection waterproof and easy to install.
The Corrapol®-BT Super Ridge comes in all four matching colours and has a flexible foam gasket to suit almost any roof angle, making a fast and easy installation. Corrapol®-BT Super Ridge is made from aluminium creating a very long-lasting corrugated roof flashing solution.
If you are choosing the Corrapol® Corrugated Polycarbonate Roofing sheets then you will need the Corrapol® Super Ridge which comes in Mill Finish or White colour options.
Bonus Tip: For these corrugated roof flashings it is crucial that you consider the ridge apex where you may have a gable corrugated roof flashing. These connections can be very tricky due to the compound mitres, however you can choose a Corrapol®-BT Super Ridge Endcap or for clear roofing sheets choose a Corrapol Super Ridge Endcap. These Super Ridge Endcaps make this complex corrugated roof flashing connection simple, fast and professional looking, with greatly enhanced waterproofing.
Use Correct Corrugated Roofing Screws
When fixing any aluminium corrugated roof edge trims, it is important to use stainless steel fixings. This is because aluminium can react with other metal or plated fixings, so using stainless steel means you can be assured it will be the longest lasting solution. For the Corrapol®-BT Super Ridge and Corrapol® Rock n Lock Gable Flashing, fixings come with the product, however Corrapol® Rock n Lock Wall Flashing may require some additional wall fixings to suit whatever substructure you are fixing to.
Choose Corrugated Polycarbonate Roofing for Clear Roofs
If are making a roof using clear corrugated roof sheets, and you want your roof to have the longest possible lifespan, after all your hard work, then it’s very important that you understand why it’s worth paying more for corrugated polycarbonate roofing. Corrugated polycarbonate roofing is typically 2000% stronger than PVC corrugated roof sheets. Corrapol® Stormproof clear roof sheets also have a UV protective layer which means they don’t discolour or become brittle with age in the same way corrugated PVC roof sheets tend to. Additionally, Corrugated polycarbonate roofing is 40% more transparent than clear PVC corrugated roof sheets.
Understand why 3m Corrugated Plastic Roofing Sheets are most common
Corrugated roof sheets can be overlapped to easily create any length, however for the majority of applications its preferable to have one continuous sheet length, if you can. Corrugated bitumen sheets are generally only manufactured up to 2m in length, however Corrapol® PVC Clear Corrugated Roofing sheets are manufactured in to 2m, 2.5m, 3m lengths. 3m Corrugated Plastic Roofing Sheets are most common because it suits the slope length of most carports which tend to be 3m slope due to the width of a typical car packing space. If you need a longer sheet then Corrapol® Clear Stormproof Corrugated Roofing is manufactured in 4m for the longer roof slope applications!
Get Corrugated bitumen roofing sheets, which colour to choose
Bitumen corrugated roofing is manufactured in Black, Red, Green and Brown. Black corrugated roofing tends to be slightly lower cost because it is manufactured in higher volumes, however there’s an increasing trend towards Red, Brown or Green bitumen corrugated roofing colours, with the relatively small additional cost provides a brighter and more creative look to projects. There is no significant difference between the colours of bitumen corrugated roofing. Corrapol®-BT is the standard bitumen corrugated roofing sheet, but for more demanding applications the heavier duty option of Awnapol® bitumen corrugated roofing sheets provide an extra level of strength.
Upgrade for Extra Durability: our new Corramet Corrugated sheets provide greater spanning, rigidity and durability. With length options up to 4 metres these sheets are excellent for longer roofs. hats more, they come with fixings provided!
Buy quality flexible corrugated roof fixings
For your corrugated roof sheets, you will need to use plastic head fixings, but as these can be seen its important to make sure these are colour matched and provide quality waterproofing. For best results it’s important that the plastic cap is flexible so it curves around the contoured top of the corrugations on the corrugated roof sheets. Using Corrapol®-BT Flexi Screw Cap Fixings also allows much more torque control with screw fixing method rather than nails. Corrapol®-BT Flexi Screw Cap Fixings are available in all four colours to match the corrugated bitumen sheet options. You can also use the Corrapol Clear Flexi Screw Cap Fixings to suit clear corrugated roofing sheets
