Design Dilemma Exteriors Kitchens

Roof covering for a flat roof kitchen extension?

4 years ago

We have a dilemma over which roof covering to use for our 3mx6m flat roof kitchen extension. Architect has put rubber in the spec but the builder has had bad experiences with this and would prefer felt/asphalt? Our e tension has 2 roof lights and a parapet around it. It wont be used for walking on. What are people’s thoughts with regard to durability and longevity?

We have rubber on ours, I think it's vastly superior to felt/asphalt if applied correctly and properly bonded by someone competent. Alternatively I understand that fibreglass is an option, but I'm not sure how costly it is.

We have chosen rubber too, north facing extension with rooflight. Could put some white gravel on top for insulation (the rubber looks a bit wobbly, but that's because we installed it ourselves, lol) and soundproofing.

If you're leaning more towards a pitched roof, perhaps you could extend your glazing right up into the gable to maximize the light coming in. I've attached a couple of images of projects where we have done just that. The first was necessary due to it being a listed building so we suggested an additional tiled roof would be more in keeping than, for example, a flat roof with a roof lantern. The second was on a lovely Victorian terrace in Coggeshall and again, we suggested echoing the original architecture with a pitched roof and glazed gable. If you would prefer an orangery style extension, despite some previous comments it is definitely possible to have a space that is a nice even temperature all year round, doesn't collect lots of flies and doesn't leak. We have built these for 30 years. All of our roof lanterns are available with solar controlled glass and motorised vents, plus the combination of masonry and glass (as opposed to a traditional conservatory which is mostly glass) provides a a more consistent room temperature anyway. We offer a 10 year guarantee on our joinery, glass and paint coatings (parts and labour) - that's how confident we are that it won't leak. We also use Accoya wood in our products which is incredibly durable, stable, moisture resistant, fungus proof, inedible to insects and thus incredibly low maintenance. It's definitely worth googling Accoya if you're considering going for a structure that incorporates timber joinery.

Dilemma - Brick flat roof extension fascia colour
Q

It’s quite difficult to see from the photos as the scaffolding is still up and we have mahogany windows which are very dated and I don’t want to keep. The fascias around the roof are black but I feel that the fascia is so large that black will be too huge and stark. I’m feeling in a dilemma. I hope the photos help a little.

HELP! Flat Roof VS Gable in Rear Extension
Q
Comments (10)
Hello, It depends on the style of your house I guess but a flat roof is generally a lot cheaper than a gable one. We are lucky in that our ceilings are higher so our flat roof doesn’t make the space feel squashed like some new homes are. It feels airy and bright because we are south facing and have two large rooflights and full glass doors across the back. The rooflights are also flat but get the morning east sun in the kitchen and the other side gets the late West sun. Well they are bright at both times of the day anyway as we are all bungalows in the area so there is nothing blocking the sun! A gable would cost more with the tiles etc but it can also give you height if you lack it (vaulted ceiling perhaps) and catch light from a different angle if you lack it. Try getting a price for your square footage for just the roof tiling vs flat roof coating and see the difference. I think ours (approx 4m x 8m) was around £2,600 ish from memory for the fibreglassing. The beams were easier to fit as well as just lengths so there was less joinery in it.

Hi Nicola - we used both types and if correctly applied, and the flashings are done properly,. you'll be fine with both. Having said that, its easier to apply a felt roof wrongly than it is to apply a rubber roof. Ask your builder for a cost comparison and check the guarantees for both - I should have stressed that more - do get the roof installed by someone who can give you a guarantee, please! ;-)
