The bottom is 16ft across, the top is 2ft across. The secps. call for 1in x 6in T&G. How would I figure how much wood it would take. Per pie or what?

Hi Rusty,
I'm not trying to be hard on you, but are you sure you want to bid something that you have difficulty calculating.
When you look at a project like this, look at your shirt first and ask "do I want to lose it".
First you find the hypotenuse, then you take the result and multiply it by 1/2(sum of narrow end plus the wide end) and that gives you the area of one pie. Multiply the area by the number of sections and you will have your total area.
Add whatever percentage of loss you need and you will know how much material you need for this job.

*Gabe - Ditto.Rusty - If your run is about 35 feet and your rise is about 10' then your rake run should be about 17' or so. With a 2' width at the top and a 16' width at the bottom that gives you about 272 sq. ft. of surface area which means you need about 550 lin. ft. of 1x6 per pie section. I think this is right, but if it were my shirt on the line, I'd calculate it about five more times before I was comfortable. Add at least 15% for waste. My next piece of advice is never, never trust anyone elses numbers. Do it yourself to be sure. Ed.

Hi Rusty,
Don't pass up the chance to monitor a job that you bid on. Remember, you are now familiar with this one.
The dollar spread is too wide to be accurate. Keep an eye on the jobsite, find out if all went well. Talk to the inspectors etc.
You can learm as much, or more, from a job you didn't get as from one that you did. There will be other jobs to bid on, but you want to make absolutely sure that your price is not only the right one, but one that makes you money.
Good luck on future bids,
Gabe
