As per their January tradition, SIG Design & Technology are counting down their top ten blog posts from the last year.
This year they are covering four blogs, including the new SIGA Natural Slate Knowledge Base which launched earlier in the year.
Here is the first half of the top ten roofing design blog posts, in reverse order. Soon SIG will reveal the top five. Tell the team what you want to read about, and maybe you can help SIG write about what you want to know in 2020.
10. Flat roof upstand best practice: updated for 2019
Towards the end of 2018 the British Standard BS 6229:2018 Flat roofs with continuously supported flexible waterproof coverings was updated, and SIG seized the opportunity to update their hugely popular post about upstands on flat roofs.
True to form this new post which covers not only the answer to ‘how high does a flat roof upstand need to be’ but also explains why upstands are needed, how to deal with level thresholds, and what to do if you don’t have the magic 150mm, together with plenty of example details for you to use, has made it to the No.10 spot.

9. BS 6229:2018 – the changes explained
Next on the list is SIG’s introduction to the changes brought about by the new BS6229. This interview with Daniel Bosworth looks at all the key changes, how they affect different types of flat roof, the effect on zero falls roofs, rainwater disposal and thresholds, and the implications for architects on the design, specification and construction of flat roofs.
SIG are generally in favour of the changes brought about by the new British Standard, particularly in how they relate to interstitial condensation risk analysis and hybrid roofs.
The changes were also welcomed by many industry bodies including the NFRC, SPRA and LWRA, and you can see statements from their technical representatives in the post.
8. Zinc clad demonstration house in Bedfordshire
The first post from the SIG Zinc & Copper blog to make the top ten is this case study of a house in Bedfordshire clad in pristine elZinc Rainbow Red, expertly worked by master installer Richard Laver and his team from RFL Metal Roofing.
SIG talk to the client, Neil Shepherd of Fairfield Homes, about this four bedroomed house, the choice of cladding finish and details, and the experience of seeing a house to showcase your company ethos come into fruition.
They also begin a conversation about the excellent gutter and ridge details, of which there will be more later. Read about the zinc-clad demonstration house and check out the fantastic photography by Terence Smith.
7. Standing seam membrane roofing on luxury housing developments
This post centres around a development of 25 luxury homes that were being built on the former garden site of a school of mission in a village in Nottinghamshire. Baxter Green features distinctive single pitched standing seam metal roofs, but they aren’t metal, they are Armourplan PSG Membrane.
The article features an interview with Nigel Fields, Midlands Area Technician for SIG Design & Technology, who describes the detailing of the project. Nigel, who won two of SIG’s ‘best roofing photo of the month’ competitions last year, went on to be highly commended in the ‘Best Trainer of 2019′ category at the SPRA awards.
Read about Baxter Green here. There are also plenty of photographs and link to the development on Leonard Design Architects’ website.
6. Liquid roofing best practice
Topping out this half of the top ten of 2019 is this article about liquid roofing featuring an interview with Daniel Bosworth and Chris Page, who are Design & Technical Manager and Product Manager at SIG Design & Technology.
In recent years the variety of liquid waterproofing suitable for roofing projects has exploded and there are all sorts of products available. Dan and Chris look at the main types, describe the advantages and disadvantages of liquid waterproofing and provide some valuable advice about choosing a system, designing the roof and what to ask about guarantees.
Since this article was written a new improved version of AH-25 has been launched, Hydrostop AH+. Be sure to contact SIG for advice and support on the most appropriate approach for your project, be it new build or refurbishment. Read the post on liquid roofing best practice here.
