Do Up Diary #52 How to choose the best cladding finish for your dormer

2015-03-05_0017

I’m so happy to be blogging that my new cladding for all four Moregeous Mansions dormers is arriving tomorrow! It’s felt like a long winter but we’ve survived it and now it’s time to get cracking again with the three remaining ‘outside’ things – the cladding, the bi-folds and the garage door. I have AGONISED over what to clad the dormers in. Constructed out of timber and externally lined with OSB then roofing membrane, I’ve kept standing in the garden, cricking my neck and imagining different types of materials and finishes on their outsides. Slate, timber, GRP, metal – all with different pros & cons and very different looks.

Dormers on traditional extension, timber, sob and roofing membraneI needed something to sit well with the tradtitonal aspect of our build, the salvaged slates, the fishtail pattern of the roof and the reclaimed bricks, but also something to give a contemporary edge and compliment with my Railings paint, contemporary bi-folds and what will be a very unique interior. I’ve decided on the finish pictured below called ColorCoat Urban by Tata Steel, a powder coated steel based product with a modern looking standing seam, good environmental credentials, a 40yr guarantee and best of all it comes in the deep grey shade so beloved at the moment – Anthracite. ColorCoat Urban Anthracite on roof

I had four greys to pick from and have opted for the far left – right choice do you think? The others look a bit pale next to my reclaimed slates, I think.
2015-03-05_0016It’s made in 514mm and 305mm wide panels and this took a bit of working out, to see where the seams would end and look the best they could, not be too close to corners and edges for example. The 305’s gave a much better vertical pattern on our sized dormers than the 514’s, something to consider if you’re doing a smaller area as opposed to a full roof. This is what this kind of finish looks like on dormers:

2015-03-05_0013So why did I pick ColorCoatUrban over other finishes? This is why:

Slate clad dormers, like the one below. are more traditional and lots of people suggested them for us. But, we have SO many slates on our complicated roof, if felt like slate overkill to have them on the sides too. It was just too…. obvious. Plus, no contemporary edge.

Slate clad dormerRendering is also a possibility but it just felt a bit too country cottage for our urban home, plus there are ongoing maintenance considerations. I do love this roof below though, it’ has quite the cutest pattern. Love the baskets too, there will be foliage at Mansions Mansions 😉

Render clad dormersThe option of horizontal timber or ‘pretend’ timber was also an option. If I’d painted timber in dark grey that would have looked good but also taken ages and been hard to upkeep. I didn’t really like the idea of a plastic or hybrid product either, plus there was the danger it could look a bit seaside like and we are in Manchester, quite a way from any beaches!

Horizontal cladding on dormersA very flat and modern GRP (today’s fibreglass) effect as below in cream or grey was considered too but it just looks a bit too characterless for my house. On new builds yes, but I wanted a touch more detail.
2015-03-05_0006What about lead work clad dormers? Well, quite apart from the fact I’m all leaded out after the valleys and box gutters, I didn’t want something which would weather and change. I’ve watched the lead work tarnish here and didn’t want that effect on all four dormers, it just looks a bit DIY to me.
Lead cladding to traditional dormerYes, you could have glass sided dormers. No, I didn’t seriously consider them for a single moment.
2015-03-05_0008So, some things to consider when choosing a material to clad your dormers are:

  • Is your build traditional or contemporary, or a mix of the two, like mine?
  • What colour will be best? Do you want your dormers to blend in or stand out?
  • Is your dormer easily accessible – maintenance is a huge consideration.
  • What’s your budget? Different finished vary in price massively
  • Longevity – is the product durable?
  • Is the product or the installation guaranteed?
  • Is sustainability important to you, can the product be recycled?
  • Take note of where you live and which direction the dormer faces, some materials are better for exposed areas and bright constant sunshine for example.

I’m happy that ColorCoat Urban ticks all the right boxes for our build and bridges the traditional / contemporary vibe really well. We can’t wait to get cracking tomorrow taking delivery and getting our hands on it. I look forward to showing you the results next week 🙂

One final point. Here is the example which drove me in my quest for dormer perfection. Can you EVEN imagine this on your home?!!

  1. Hi Jane.

    I’ve just come across your blog while looking for dormer cladding materials. Very helpful. I too would prefer a more modern style to contrast with my ’20s house. I am also adding a rear extension and would like the roof (flat or pitch… tbd) to match and align with the dormer.

    Have you been happy with your dormer? Can you give an approximate cost. Do you have pictures?

    I haven’t yet started work, so no decisions yet.

    Many thanks, Lou

      1. Oops! Sorry, Sian… I was reading the above message from Jane!

        I specified ColorCoatUrban Anthracite for my full-width Dormer and single-storey rear extension cladding, thinking it would be covered under Permitted Development. I applied for a Lawful Development certificate in March just to cover myself, then the Council came to a halt! I’ve just had Planning sign-off, but the Planner turned down the dormer cladding. If I want it, and there’s no guarantee I’ll get it, I need to submit a full Planning application (plus another fee!), which would take at least 8 weeks and probably longer in the current situation.

        I can’t delay for another 8-12 weeks. My chosen builders are desperate to get back to work, and if I don’t proceed now, I will lose them.

        I’m very disappointed. Your cladding looks amazing. But I will now proceed with cladding in tile for the Dormer, but I will go for ColorCoatUrban for my extension roof, with black ‘Crittal-style’ doors and window surrounds.

        Budget is now likely to be an issue. Do you have any advice on whether I go for steel or aluminium for the doors?

      2. Hi Lou
        Sounds fab!
        If you want a photo of my dormers to show the planner, I’d be happy to send you one. It looked superb against reclaimed slate on the original Edwardian house.
        I have done a blog post on our St Albans build for Your Home Made Perfect where Laura spec’d Crittal style. Used a great co, have a gander x
