Simulated Tar Paper Roofing

I thought I would throw my hat in the ring and show how I do Tar Paper roofing.

I will use brown wrapping paper, the kind used for mailing packages through the mail.  One roll will last an eternity and do untold numbers of structures.  :D

As I work in 'O' scale, I will normally cut strips 3/4" in width and 6" in length.  This, of course, represent 36"x24' pieces.  You can, of course, make them any length and width you want.  I choose this length for ease of managability.
You can also just roll these up and make them as unused roofing rolls.  Good warehouse dock loads! How about a truck loaded with these heading to a roofing job?  :) :)





Placing the strips on another piece of wrapping paper, I will then color them using an A/I mix of black India ink and alcohol.  These inks do come in other colors.  I buy them at a local art supply store.





I will allow this to dry between applications.  I usually end up doing about three.  The amount of ink you have in the mix of course, will determine how dark or bright a stain you end up with.
The side you stained, will end up pretty solid in color.  The back will usually be a blotchy mix.  I have used both sides.
You will notice on the example, that the darker side, is varigated.   How is it that Bob Ross used to say, "there are no mistakes, just happy accidents!"  Nothing is beyond using.  ;)





Then, whatever size roof you are wanting to cover, start laying it out.  I always leave an overlap on the roof edges.





Using white glue as my adhesive of choice in this,  I work my way up the roof.  Overlapping the next over the next...etc..













Using my trusty razor blade, I will go under the overlapping and lift.  Giving the look of dried out and lifting tar paper.



If you want it to look newer, skip this step.



If you want really aged tar paper, then take a brush with just plain water and soak some spots of the roof.



Then just start worrying it with a razor blade or your finger.







Once I have it where I want it, I then using weathering powders to finish 'er off!





This particular roof, is for a small pump house for the engine service facilities on the HWCRR.



Here are pics of a couple of structures I have used this method on.

I've had good luck using telephone book paper for tarpaper/roofing paper or canvas roofing in HO scale.  I treat it pretty much the same way you do here.  The telephone book paper is thinner and has a finer texture appropriate for HO scale, and it'll get realistic small wrinkles when you glue it down.

What is a telephone book?
It's a hardcopy printout from your LDAP server.
