O.K. I messed up and need some information

Make a new roof that fits your space.

Dave

Two ways to address the issue to visitors to your layout:

Number 1: That's not a "gap" in the roof, that is a new, experimental "natural air flow vent" system to cool the building.  Yes, it is a little inconvenient during winter snows or rainy days, but the tenants have learned to put up with it.  What really bothers them are the birds who see it as an invitation.

Number 2: Well, the lawsuit between the owner of the building and the owner of the construction company turned just a little ugly. Let's just leave it at that.

If you don't like those two...

The "chipboard and masking tape" works fine.  As would buying a piece of styrene and replacing the factory roof.

I have also seen people simply cover their "error" by taking appropriate looking (grit) sand paper, spraying it an appropriate color, and then putting that in place to hide seams, etc.  (Might want to make it much larger than you need and hold down the corners while the paint dries so it dries "flat" and does not "curl".)

But I kind of like the first two solutions...

I need pictures! It's very hard to solve a problem that I can't visualize.

O.K.  Hear is my mistake.

Seems like an easy fix. Either infill the gap with a similar material, or measure up a completely new roof and glue it on top of the old one, then apply new "tarpaper". Personally, I use fine sandpaper that's painted with Polly Scale Tarnished Black, then weathered with powders...

Scot,

You could put a firewall in that spot. You could make it with a simple piece of wood the same height above the roof as the other exterior walls. It can be painted black to match the roof. Styrene would also work easily.

The roof panels are available as single pieces. I would fabricate a patch.

These pieces of the Barrettsburg model were incorrectly cut. I fabricated a corner "fitter" from the mistake with two roof pieces and brick wall end pieces , cut to fit.  Flat roof section.  Click on the underlined phrase to link.

I cut the pieces with a band saw, small tooth (hacksaw blade), and finished the cut edge with a small sanding block.  Roof panel picture is from the OGR website.  Almost all the parts available in the kits are available for kit bash.

use masking tape and paint it black. just cut strips about 1in long and over lap them it will look like tar paper when you paint it.

Another alternative would be to make a short wall to fill the gap.  Just bond it to either...or both...of the roof pieces.  Don't worry about the tile wall capping...I'd just fake it with some segmented (cut grooves) thick styrene strip stock, sanding/rounding the edges.  Lots of embossed brick styrene to choose from to facilitate the wall itself. 

It would be as if the smaller building had been built as an addition to the original larger one, retaining the original walls. Lots of real world structures end up that way as they grow addition-by-addition.

Just a thought, FWIW, always...

Put in a filler then get some old phone book pages and tar paper it then gravel it.

Scot I don't see where you've make a mistake.  The only thing I see is that you still have to add the firewall.

Use anything to fill the gap, plastic sheet, matt board even scrap package material. Then use wide 2 inch or so masking tape over the gap.....paint it all black,,,done!

Thank you all for your tips. I'm going to use them somehow, and I'll let you all know how it goes  again  Thank you all.     Scot

I bash Ameritown building kits and make buildings from panels so often that I almost never have a completed building on which the provided roof fits.  I've found that black, 1/4 inch tick foam-core board bought from staples is very easy to use to make a very suitable new roof. I turn the building over (roof side down) and put it on top of the foam-board, then press each panel into the foam-board enough to leave small indentations where the roof edge was.  I then use an X-Acto to trim about 1/8 inch outside of those to get a roughly roof-sized piece that is a bit larger, then finally trim it carefully down to fit inside like it should.  I must have a dozen buildings with this type of roof.  Some I paint, some I cross with small knife-point creases, etc., but all of them look fine.

Don't waste your time!

Get some of the roofing crew figures from Arttista up there on the roof and let them figure out what the problem is and how to fix it!!! 

Now we're talkin'.   

That building is great! I can almost smell the hot tar...

Hey, Scot, I agree with the new cross brick section idea like the wall surround already is...you can make a simple styrene short wall as high as the outside walls and add thin brick sections to it to mimic the brick.

My 2 cents...

Hello guys. I'm still Thinking this over on what I plan to do. I have been working on this model and will decide soon. I love all the tips so far and want to thank you guys for offering them.  Scot

Scot,

I offer a number of resin castings for roof details that may assist you in solving your problem at the same time adding a customized appearance to your building. Take a look at my web site www.westportmodelworks,com

Just adding my two cents worth (hope you don't mind). I was painting the roof on A gas station and picked up A can of black spray paint and shot the roof on the front porch. Went back to painting tree armatures for an hour, went back upstairs to the front porch to get the roof picked it up and realized what an idiot I am. The roof is all shiny I painted it with gloss black so back down to the basement get the flat black this time and repaint the roof. Back down the basement painting more armatures for another hour go back up to the front porch to get the roof took one look at it and now I'm really PO (ten thousand tiny little cracks that are shiny black and the rest of the roof is flat black. Now I'm ready to smash the roof off the ground. My dad yells at me to calm down I told him that I've got to strip the two layers of paint off and when I do the plastic roof is going to melt and warp from the paint thinner. He is telling me to leave it alone he said that A flat tar roof when the tar sort of dries it looks flat but as it dries it shrinks and the cracks look shiny so I left it alone put the roof on the gas station and it looks good so if you are interested in giving it A shot try it on A scrap piece of plastic and see what you think. Hope you like the idea Choo Choo Kenny

Hello everyone.  I think I might go with http://www.westportmodelworks.com/  and use their sky windows. Can you guys give me a place to look for these little detail items for adding  such detail to a model.  Thank again.    scot
