Frequently asked questions
FLEXIROOF DESIGN
What is Flexiroof made from?
We use high tensile aluminium (70% stronger than normal aluminium), premium 3mm polycarbonate sheet, and stainless steel fasteners.
Is polycarbonate sheet available in clear?
No, clear is too hot! We offer a medium grey sheet, cutting out:
~100% of UV radiation
~50% of visible light
~20% of heat
This is the best Goldilocks solution. Not too dark, not too light!
We only use polycarbonate sheet because it is 15x stronger than the cheaper acrylic or perspex alternative many other companies use.
How does Flexiroof handle snow? High-wind? Salt-water?
Flexiroof shelters not only look great, but they are also designed to last for decades, even in New Zealand’s wildest weather situations.
Snow
Under snow load, some sag will occur, but as the melt occurs, our strong and elastic materials will return to their original forms.
Normal window aluminium has an ultimate tensile strength (UTS) of 150 MPa. Our rafters have internal bracing ribs are made from higher tensile 6016 T6 aluminium (UTS 235 MPa.) and all our other extrusions are made from the even stronger 6106 T6 aluminium (UTS 260 MPa.)
High-wind
To ensure Flexiroof handles high-wind we:
Use 3.00mm sheet and trap it with geometry video so there are no holes in the sheet (corrugated polycarbonate is only 0.9mm thick)
Use polycarbonate sheet – 15x stronger than common acrylic or perspex alternatives
Use 10mm stainless fasteners
In exposed places, during storms there may be sheet noise (in keeping with noises from the rest of the house!)
We had several shelters hit by the Auckland West tornado in early 2018 and they all survived well.
Salt-water
Flexiroof uses:
6061 T6 aluminium and polycarbonate sheet which are inherently very corrosion resistant
Stainless steel fasteners – all steel will corrode over long periods of time when exposed to sea air
A note regarding galvanic corrosion: “battery corrosion effect” can occur with dissimilar metals (such as stainless and aluminium) but for it to occur it needs moisture, salt, and a lot of time. If you are putting aluminium windows (or a Flexiroof shelter) on a fishing trawler you will definitely have a problem. Otherwise, here at Flexiroof we are certain we are using the best system possible.
PAYMENT
Do you offer finance?
Sorry, not at this time
What kind of warranty do you offer?
An industry-leading 15 year warranty.
DELIVERY & INSTALLATION
Do I need a permit?
In New Zealand you do not need a permit for any of our shelters that are less than 20m². We often put independent shelters adjacent to one another, that are all less than 20m² but combined over more than 20m² with no permit.
How long does it take to deliver / install?
Our shelters are made to order so our normal delivery time of kits to your agent is:
6-8 weeks for the North Island
8-12 weeks for the South Island
If this is too long for your project, or you have a big family event approaching, please let your agent know, and we can see what we can do!
How much does installation cost?
Please see ouronline pricingfor an estimate
Do you offer Flexiroof as a DIY kitset?
Yes!, and even better Flexiroof allows you to quote online for a Flexiroof Light DIY kit!
FLEXIROOF OWNERS
How do I clean a Flexiroof?
We recommend using 30 Second Roof & Awning Cleaner every 6-18 months (depending on your roof’s location).
- Clean it after rain so the things on the roof have had time to soak in water and soften.
- Test cleaning whatever is on the roof off in an area less seen just to see how it comes off first before doing a larger area.
- Don't get too aggressive with cleaning if everything is not coming off. Put some more product on it and give it some more time to do its job
- To use a microfibre head on your cleaning implement
