I have a old shop building at my mother in laws that is in desperate need of a new roof. The roof has been allowed to deteriorate to the point of needing new sheeting. I do not know how long she will own the property and the apperance of the roof is not that important. Any ideas on using roll roofing. I know it cannot last as long as shingles but the cost is quite lower and I can easily install it in a short period of time. The roof pitch is 4/12.
Any thoughts or suggestions as to whether the added expense of shingles is warranted if she may only own it a few more years?

DUH???
Well, me cheaper than most, FHB Nov '90 GM had a description of my cabin roll roofing. Am now reroofing with 3tab arch type shingles.
That said, unless your slope is less than 2/12, and you value your own time at more than 10 cnets/hr, 3 tb is better. \
Did my own mom's house in shingles vs roll. 6/12 slope. Had to travel 2000 mi. for that job, shingles were only 20% MORE $$ AND lots less labor.
On a 4/12 slope, IMO you would be extraordinarily foolish to do roll unless your finances are truly in real desperate shape.
So how are shingles less labor than roll roofing?

A roll of roll roofing is about 30.00 for 100sqft. A square of 20 year shingles is around 52.00. I have never installed roll roofing but I imagine that I can install it in less than 1/4th the time I can put down the shingles. Where is my math off?
You said that you were just reroofing your roll job done in 1990. That is 18 years. Most of the "20" year shingles I have seen are lucky to make it 15.

Not if you do it right, if you do it right, it will take LONGER to install roll roofing than shingles (assuming you have a coil nailer).
Only proper roll roofing install IMO is 50% selvage type overlap, all seam bonded with cold process adhesive, etc. Which, btw, runs the cost to the same as shingles.
