It took about three weeks of labour and just under three grand in cost to redo the shingles on my roof. It was just over two grand for the shingles, the rest for misc. Not including me taking two weeks off of work.
About three weeks because I didn't do it all at once, an 11/12 pitch is tiring to work on. One week per side of stripping/waterproofing, then a couple weekends of shingling.
Edit: the stripping took a week from having two layers of shingles, first layer was cedar than asphalt.
If he had been paying a crew and not doing it themselves most roofs can be done in part of a day with shingles. And most often by meth addicts or illegal immigrants because nobody else will do that horrible job for the prices they ask, not to mention a skilled tradesmen.
In some areas when big enough hail or storms goes through a town 1 or 2 crews will jump on the insurance payouts and take the low bid if they can do them all at once. And within a week or two at worst the entire neighborhood or small town is reshingled.
Yep, I only did my roof because I had some free time (planned for, excluding weather).
That and saving $20 000 or so in labour. I was quoted $8000 just to remove cedar shingles not asphalt as well (off-hand by a buddy). This is in $CAD.
As well as doing a better job than most of the roofs I've redone, whole lotta hack jobs on roofs since you'll never see the problem or deal with it till the contractor is long gone.
Someone else suggested that you have to replace your roofs every 25 years though. People definitely live for 25 years!!
Also even if you personally don't live that long, it does affect the value. For example a 99 year lease on a property is considerably less valuable than a 999 year lease, even though very few people live more than 99 years.
25 years is common but most places allow 2 or 3 shingle overs that don't require a tearoff. They just slap a naked layer of new shingles over the old which is even cheaper than the first roof/layer.
The shingles used in the us are a good compromise. They are cheap and easy to repair. Clay lasts well overall but one broken tile is going to be expensive to repair.
