In that post I told how on January 1, 2016 I borrowed a friend's brand new trailer and went and bought 50 squares of shingles that were on sale. 

That is a gable roof with a three tab composition shingle which is the cheapest shingle on the market.

As a GC I can advise try to retain control of your finishing material orders (anything where you need to make a choice ((tile, flooring, lites, faucets, tubs)) vs. construction materials (2x4s, mortar, shingles)) because we get those discounts on the finishing items and we keep them!

Also, be sure to set up some Keyword Alerts for some of the topics you are knowledgeable about, or other topics that interest you (likmy computere wholesale, New York, Rehab, etc ) so you'll be notified that those words were mentioned in the forums and can jump into those conversations!

You go metal right over the shingles.  

When I say hodge podge, the shingles on the roof don't line up correctly...or match!

Simply put, you drive around neighborhoods looking for distressed properties (Boarded windows, uncut grass, missing roof shingles, etc.) and write the addresses down. 

In the old days, grandpa would buy the shingles and spend his week of vacation from the factory replacing the roof when it was needed.

If your short one piece of drywall or one bundle of shingles .

When repairing an existing home, there always seems to be some sort of a surprise... termites, underground plumbing, lots of wood-rot under the shingles, you name it...
