Corrugated Roof - Construction/Roof Openings

howman

Hi all

New to the forum, but in need of advice/recommendations etc

We are midway stage of planning.

Site is sloping, south facing, entrance at top of slope, house design living upstairs/sleeping downstairs, roof design is curved corrugated “barn style”

Construction style for house is not yet finalised, but it will be a concrete slab / concrete stairs system, yet to decide on blocks or ICF type construction

Anyone gone down this path before?

The roof is my main concern and getting head around its construction

The curve is too tight to use one piece kingspan commercial type panels, so Im assuming it will be corrugated aluminium sheets, with insulation / sound proofing membrane etc

Has anyone eperience with this? Is it noisey?

I am concerned about having openings throught the roof (chimneys, electrical cables), as leak paths maybe difficult to avoid?

Even fixing the sheets to the supports has me worried of leak path developing over time?

Was thinking of bringing chimneys out through side walls and removing any stoves not on side walls

Has anyone worked with this type of roof and experienced any diffculties?

thanks

I'm not a builder/tradesperson but when I contemplated a corrugated metal barrel-roof for a modest extension the universal response I had from trade, surveyors, etc., was that it would be expensive as the aspects you mention are highly-technical and difficult to accommodate, and the supporting beam-structure more complicated.

We didn’t exactly over research the roofdesign beforehand but recent neighbouring builds had traditional apex roofsreplaced by curved/flat designs during the planning stage, to decrease impactof builds on locality (very close to protected area), so we embraced the designand build the house to suit the barn style roof

At the time I thought one piece panels wouldwork but unfortunately not (with kingspan/tegral anyways)

Anyone work with another potential supplier?

So now Im freaking out a little ( a lot) overpotential issues of the roof

Deciding not to have any openings through theroof for this reason, not sure if that is being overly dramatic?

1. dont be, with good arch detailing it will fine, you'll find there are several options available to you, whats the width of the roof,whats the arch height &/or radius?
2. your arch should be capable of designing a building without roof-lights. that said there is no issue crating chinmey flashings etc through such a roof - its common. you may just want to vet the roofing company a little more thoroughly than you might with a slate roofer

Perhaps using flat sheets near any opes may result in a stronger seal being formed?

layout of roof
main "barrel" running east to west, width 9.5m, length 15.5m, radius 2.4m
short roof barrel sections, running north south, joining at ends of building, width 5.5m, length approx. 6m, radius 2.4m

Hi,i think you should avoid this as this might confuse you with the sloping. To overcome this problem you can either ask for structural damage assessment or structural repairs for the corrugated roof and its construction.

not sure what point you are trying to make here....spam perhaps?

Hello Howman when you use this type of roofing you may find that you are very limited when you try to insure it. My advice would be talk to broker first . Many companies are reluctant to quote for domestic building with this type of roof.

where have you come across this?
have not checked into it but , on the basis that they are at least 4no. similar roof styles within the area, its not exactly an unknown build?
