It also can save time, money and won’t open a home up to the elements during the process. Read on to learn how our CF system works! ## **WHY CONCEALED FASTENINGS? ** The concealed fastening system allows the panels to be fixed directly to a plywood substrate, or to battens. As the batten fixing space can be matched to the old tiles, you can install the CF panels directly over your existing asphalt shingle roof. This makes Tilcor’s CF Shingle the fastest stone-coated steel shingle roof to install. The concealed fastening system also adds a layer of protection, even in the harshest environments. Tilcor products are fire-resistant to the highest standards and wind resistant in extreme conditions, up to 120 PMH. A  UV-resistant coating is also added to protect from harsh ultraviolet rays. Worried about earthquakes? Tilcor is considered a “lightweight roofing system” and the interlocking panels mean the roof is less likely to give under structural pressure.  A lightweight Tilcor roof saves you money and time, whether it’s a re-roof or a new build. ## **DESIGN OF TILCOR ROOFS** Tilcor’s CF profiles have been carefully designed to preserve the familiar appearance of a traditional shake or asphalt shingle roof. A range of natural, weathered tones are available, so that you can recreate the rustic appeal of timber, or asphalt. These profiles have been cleverly engineered to resolve the ongoing issues suffered by many homeowners with traditional roofs. The solution is largely down to the innovative concealed fastening system. Roofing panels interlock, resisting wind lift and fully sealing fixings. As all fastenings are protected from the elements, these roofs are watertight and reliable in a way that wasn’t possible before. Other shingle roofs are prone to lifting, delaminating, and generally breaking down. This is caused by high winds and strong UV rays. In contrast, Tilcor’s CF profiles are highly durable, delivering world-class performance. - [Tweet](https://twitter.com/share) [« prev](https://blog.rossroofgroup.com/tilcorusa/climate-change-contributing-to-need-for-better-roof-materials) [next »](https://blog.rossroofgroup.com/tilcorusa/cf-shingle-makes-stone-coated-steel-install-faster-easier) ### Recent Posts ### POSTS BY TOPIC - [November 2017 (3)](https://blog.rossroofgroup.com/tilcorusa/archive/2017/11) - [June 2018 (3)](https://blog.rossroofgroup.com/tilcorusa/archive/2018/06) - [July 2018 (3)](https://blog.rossroofgroup.com/tilcorusa/archive/2018/07) - [September 2019 (3)](https://blog.rossroofgroup.com/tilcorusa/archive/2019/09) - [November 2019 (3)](https://blog.rossroofgroup.com/tilcorusa/archive/2019/11) - [May 2017 (2)](https://blog.rossroofgroup.com/tilcorusa/archive/2017/05) - [October 2017 (2)](https://blog.rossroofgroup.com/tilcorusa/archive/2017/10) - [May 2018 (2)](https://blog.rossroofgroup.com/tilcorusa/archive/2018/05) - [August 2019 (2)](https://blog.rossroofgroup.com/tilcorusa/archive/2019/08) - [April 2020 (2)](https://blog.rossroofgroup.com/tilcorusa/archive/2020/04) - [May 2020 (2)](https://blog.rossroofgroup.com/tilcorusa/archive/2020/05) - [June 2020 (2)](https://blog.rossroofgroup.com/tilcorusa/archive/2020/06) - [July 2020 (2)](https://blog.rossroofgroup.com/tilcorusa/archive/2020/07) - [September 2020 (2)](https://blog.rossroofgroup.com/tilcorusa/archive/2020/09) - [December 2016 (1)](https://blog.rossroofgroup.com/tilcorusa/archive/2016/12) - [March 2017 (1)](https://blog.rossroofgroup.com/tilcorusa/archive/2017/03) - [July 2017 (1)](https://blog.rossroofgroup.com/tilcorusa/archive/2017/07) - [August 2017 (1)](https://blog.rossroofgroup.com/tilcorusa/archive/2017/08) - [January 2018 (1)](https://blog.rossroofgroup.com/tilcorusa/archive/2018/01) - [March 2018 (1)](https://blog.rossroofgroup.com/tilcorusa/archive/2018/03) - [April 2018 (1)](https://blog.rossroofgroup.com/tilcorusa/archive/2018/04) - [August 2018 (1)](https://blog.rossroofgroup.com/tilcorusa/archive/2018/08) - [October 2018 (1)](https://blog.rossroofgroup.com/tilcorusa/archive/2018/10) - [February 2019 (1)](https://blog.rossroofgroup.com/tilcorusa/archive/2019/02) - [April 2019 (1)](https://blog.rossroofgroup.com/tilcorusa/archive/2019/04) - [July 2019 (1)](https://blog.rossroofgroup.com/tilcorusa/archive/2019/07) - [October 2019 (1)](https://blog.rossroofgroup.com/tilcorusa/archive/2019/10) - [December 2019 (1)](https://blog.rossroofgroup.com/tilcorusa/archive/2019/12) - [January 2020 (1)](https://blog.rossroofgroup.com/tilcorusa/archive/2020/01) - [February 2020 (1)](https://blog.rossroofgroup.com/tilcorusa/archive/2020/02) - [August 2020 (1)](https://blog.rossroofgroup.com/tilcorusa/archive/2020/08) see all ![](https://blog.rossroofgroup.com/hs-fs/hubfs/CTA.png?width=400&height=237&name=CTA.png "CTA.png") ![](https://blog.rossroofgroup.com/hs-fs/hubfs/CTA.png?width=400&height=237&name=CTA.png "CTA.png") [![stone-coated-steel-video-series](https://hubspot-no-cache-ap1-prod.s3.amazonaws.com/cta/default/2382472/214894a4-4069-487d-863f-a8636fb35e8e.png)](https://hubspot-cta-redirect-ap1-prod.s3.amazonaws.com/cta/redirect/2382472/214894a4-4069-487d-863f-a8636fb35e8e) ### Subscribe to Email Updates [Tilcor Privacy Policy](https://content.rossroofgroup.com/privacy-policy-tilcor) [![Ross Roof Group](https://blog.rossroofgroup.com/hubfs/RossRoofingGroup_Jul2016/Layout/RRG-logo.jpg "Ross Roof Group")](https://rossroofgroup.com/looking-for-roofing-products) ![Fast Deloitte 50](https://blog.rossroofgroup.com/hubfs/RossRoofingGroup_Jul2016/Layout/NZ_Made-logo.png "Fast Deloitte 50") [![MRM](https://blog.rossroofgroup.com/hubfs/RossRoofingGroup_Jul2016/Layout/mrm-logo.jpg "MRM")](http://metalroofing.org.nz/) [![roofing-association](https://blog.rossroofgroup.com/hubfs/RossRoofingGroup_Jul2016/Layout/roofing-association-logo.jpg "roofing-association")](http://www.roofingassn.org.nz/) [![nz-steel](https://blog.rossroofgroup.com/hubfs/RossRoofingGroup_Jul2016/Layout/nz-steel-logo.jpg "nz-steel")](http://www.nzsteel.co.nz/) ### like what you see? get a quote!
