Mono Pitch sloping roof - Planning exemption

chris scanlon

hi sorry to post a question on my first post but i hope u might be able to help me.

Currently building a shed out my back. The roof im putting on is a mono pitched roof (High at the back wall sloping down to the front wall).
After construction the back wall will stand at 3.5m.

My question is since the roof is not a apex roof and is a sloping roof would i get away with the 4m roof height exemption. i have read the exemption and t doesn't specify what type of pitched roof (tiled pitched roof - 4m).

Any help greatly appreciated.


Thanks for you time.

Chris.

4m height for any pitched roof. A mono pitch is still a pitch.

+1 as long as it cant be construed as a flat roof with a v gradual slope

I don't think that can actually happen. As it must be tiled or slated.
I don't know of any tiled or slated finishes that can go on a flat roof

You could put a tiled or slated finish on a flat roof.
Wouldn't be much good at shedding rainwater.
I wonder is this one of those "gray areas"?

This the exempted development schedule for Class 3 Exempted development:

"CLASS 3

"The construction, erection or placing within the curtilage of a house of any tent, awning, shade or other object, greenhouse, garage, store, shed or other similar structure.

"1. No such structure shall be constructed, erected or placed forward of the front wall of a house.

"2. The total area of such structures constructed, erected or placed within the curtilage of a house shall not, taken together with any other such structures previously constructed, erected or placed within the said curtilage, exceed 25 square metres.

"3. The construction, erection or placing within the curtilage of a house of any such structure shall not reduce the amount of private open space reserved exclusively for the use of the occupants of the house to the rear or to the side of the house to less than 25 square metres.

"4. The external finishes of any garage or other structure constructed, erected or placed to the side of a house, and the roof covering where any such structure has a tiled or slated roof, shall conform with those of the house.

"5. The height of any such structure shall not exceed, in the case of a building with a tiled or slated pitched roof, 4 metres or, in any other case, 3 metres.

"6. The structure shall not be used for human habitation or for the keeping of pigs, poultry, pigeons, ponies or horses, or for any other purpose other than a purpose incidental to the enjoyment of the house as such."


As you can see there are several issues that affect it apart from the overall height.
To answer your specific question, and notwithstanding my earlier tongue-in-cheek reply to Mellor:

"tiled or slated pitched roof, 4 metres "

You're looking at a slope of around 30 degrees, I think.

However it would be best if you were to ask your local planning officer for his/her interpretation.

This is what I had in mind when I posted earlier.
Had a case with SDCC where the 'shed' had a proper 'flat' felt roof under slates which were only fixed on to try get around the 3m rule.
It failed to get past because the slope was less than 10 degrees

I threw in the comment as a joke.

But with an underlying nugget of truth.



There are a few inconsistencies like that one lying in wait for the unwary.

Certain slates - reconstituted - can be set to 20 Degrees

I know of a concrete tile that can be set to 17.5 degrees

Both would still qualify as pitched roofs imo.

Unlike profiled sheets that can go to 4-10 degrees.
Not a pitched roof, But would be interestign to see what would happen if used at say 20 degrees. I think it wouldn't qualify for tiled or slated (dispite be plastic/rubber/metal tiles).

Interesting point.. what exactly constitutes a pitch? Even flat roofs have to drain.

Mellor

Flat roofs do have a fall. For, as you mentioned, drainage. But not so much so as to class them as "pitched"

how its defined is pretty simple,
<10 degrees = Flat roof
10-70 degrees = Pitched roof
>70 degress = Walls

These are just the guideline def, in reality,
pitched roofs are in the 20-40degree range, and only mansard sections approach 70.

Is this one of the double-interlocking variety?

Another landmine waiting for the unwary.

Where the roof of the house is tiled or slated, what about the shed roof covering?
What happens if you use say wood shingles as a roofing material.
Nice to look at, visually not a problem surely?
Or even that old standby, felt?

In theory they don't comply.

Coming back to your profiled metal sheeting and I think this is where the problem may have arisen initially.
Sheds were often constructed of corrugated metal or asbestos sheeting laid to a fall, giving an "industrial" look to the backlands of residential areas.
I suspect the rrequirement for slate or tile wasn't to make what could normally be a temporary storage structure more permanent, but to maintain the visual amenity of the area.

Yes , R*******d 49 I think it's called ( avoiding trade name )

Geez, this pussyfooting around is annoying.

As long as you preface your comments to preclude them being read as statment of fact you're reasonably well covered on the less extreme utterings.

Anyway, yes, I thought so.

I had a garge conversion to do many years ago and the clients wanted a pitched roof and we used a similar special tile - touch wood, no problems.

Shingles would have to get planning I suppose, unless it was kept under 3m

I was actually refering to the newer profiled sheets that are designed to look like tiles.
There can be laid to very low pitches, and could in theory be used for a flat roof. Imo these would be subject to the 3m height exemption regardless of pitch, as they aren't what would be considered "tiled or slated", dispite their looks.

Yep, that's my call on it, odd as it seem, because of the specific wording of the exempted development schedule.

Yep, I think that's the call on it as well - beauty being only skin deep in such cases.
