Roofing a House, 2-roofing techniques to improve lego homes

I have already brought up some basic house building techniques in a previous post.
In this post i will continue with the basic roofing of houses.

Lego just recently released info on another one of their big sets for next year.
This time it was the                                      

10243 Parisian Restaurant. After taking a closer look at this model i realized that the roofing was rather abnormal for Lego. This model featured some large sloping elements to form the roof. Often techniques like these are excluded from official lego sets. 

Now, as mentioned before, most lego houses are designed for a beginner's age group. so, more complex roof designs are excellent to find in new sets. 

with this all said, it's time to get to the building tech part of this post:
House roofing techniques....

Lego to release a small scale model of the "Maersk Line Triple E" !!!

The first Triple-E to be launched: The Mc-kinney Moller
Passing through the Suez canal on its maiden voyage. 

Lego has always had a way of taking advantage of the release of "the next big thing".
This time, it's the world's biggest, energy efficient Maersk Triple-E!!!

20 of these ships are to be constructed over the next few years and will be launched to ship over 18,000 containers at a time!!!! These giants span about 400 meters long and 59 meters wide. The ships are much to big to dock in the Americas. They are designed to cross the Suez Canal in Egypt in order to preform trades between Europe and Asia.

under construction!

The Triple-E will be able to carry 2,500 more containers than it's predecessor the E-class Emma Maersk.
"One of the class's main design features are the dual 32 megawatts (43,000 hp) ultra-long stroke two-stroke diesel engines, driving two propellers at a design speed of 19 knots (35 km/h; 22 mph). Slower than its predecessors, this class uses a strategy known as slow steaming, which is expected to lower fuel consumption by 37% and carbon dioxide emissions per container by 50%. The Triple E design helped Maersk win a "Sustainable Ship Operator of the Year" award in July 2011." -- Wikipedia

Why is this big news for Lego? If the reader hasn't noticed before, Lego has a habit of designing sets based off an upcoming theme. Take lego Cars for example, just

The five basic tips every house builder should know.

    

Recently, lego creator saw the release of the new Family House. I personally have had a chance to mess around with this set and I find it disappointing. Although it may "look cool" it has a low piece count (756p.) and price per piece is high averaging at 9 cents a piece. This includes all the minifig elements and accessories. so i do not fancy this decline in value of lego sets.

Now I could go on and on about how awful a set this is, including the fact that the garage opens directly into the living room where a kitchen should exist, but I have a different point to make.

The standard for lego houses could be so much better. Take the modular buildings for example.
The 10218-1: Pet Shop has neat techniques and lots of space for it's size. If you haven't seen this model displayed before, it's HUGE! So, why aren't Lego houses this good?

The two reasons I figure are:
