The new hipped-roof planning
Our house was extended in 1932 and a small flat roof was used above a corner window. We have never liked the style of this roof and it ala had problems with water leakage so we decided to replace it with a small tiled hipped roof to improve the overall look of the house.
I've used a hipped roof to maintain visual compatibility with the rest of the house. As described on Wikipedia: "A hip roof, or hipped roof, is a type of roof where all sides slope downwards to the walls, usually with a fairly gentle slope. Thus it is a house with no gables or other vertical sides to the roof."
Task number one is to determine whether I need planning permission to change the small flat roof to to a hipped roof. This is usually achieved by talking to your local planning department and asking them for their views.
I had hoped at first in this case I would not need planning permission as was the case with my house extension but it was not to be.
The reason being that (as can be seen on the government's Planning Portal). The permitted development rules allow for roof alterations without the need for planning permission, subject to the following limits and conditions: "Any alteration to project no more than 150 millimetres from the existing roof plane."
The cost of applying for planning permission turned out to be £160.00.
An on-line planning application can be made via the Planning Portal.
After I submitted the planning permission with my plot map, the local council rang to ask whether did I had permission to use the 1:1250 Ordinance Survey map of the plot for copyright reasons - that I have used several times in the past. I said I didn't and this drove me to go to the Ordinance Survey web site http://www2.planningrequired.com/ to buy a plot map. This involved more cost with a bill for Â£31.80 which gave me a license to use the map ten times.
Further, it became clear that I also needed to involve Building Control department at a further cost of Â£195.00 including VAT. I used "Building Notice" which does not involve full plans submission.
I had estimated that the materials cost for the new roof would be about Â£500 so the total local council charges were nearly the same amount. Phew!
In the planning application I had to provide three views.
This is the roof as it was - flat and felted.
Front projection of the proposed roof complete with dimensions.
The north facing view.
Within a few days of applying for planning permission the usual public notice was displayed outside the house.
Let's hope nobody objects!

The planning application is displayed in the local newspaper.
Planning permission approval dropped through the door this morning in the normal ubiquitous brown envelope.
Now I guess I have to address building regulation issues so the first thing to do is to do is fill the form and pay the money! Time to go to the building regulations page.
As planning permission for the hipped roof was required, the building control department needed to be involved so some more money needed to be spent to pay for conformity inspections.
I originally was only going to build this small hipped roof but I eventually decided to re-roof the whole house.
As more than 50% of the roof was being replaced, I needed to upgrade the roof insulation to current standards - to quote:
"Following the publication of the EU’s Energy Performance of Buildings Directive, in April 2006, Part L of the Building Regulations was revised together with its Approved Document.
Part L deals with the Conservation of Fuel and Power in Buildings. The revision of the Approved Document aims to reduce energy consumption by 20% in comparison with the 2002 level.
These regulations affect your property if you intend to repair or replace more than 50% of the surface area of your roof, or more than 25% of the total area of the building envelope."
This caused me many issues as you will see later!
