roofing time and plywood spec

I'd like to get an idea of how long it would take a 6-7 man crew to completely redeck, shingle, and dispose of, my existing roof. Here's the basic layout of my 1500 sq ft home's roof. I've been told it's about 36 squares. We're located in Houston, Texas.





Last, my rafters are on 24" spacing. What size plywood, with radiant sheathing, is best? 1/2, 9/16, 5/8?

If they are all competent roofers and the weather cooperates, 2 days max. 1/2" sheathing with H-clips between rafters would be the bare minimum, but IMO I would suggest they use 5/8".

I vote with XSleeper, the thicker the better (especially if the cost difference is negligible). That being said, however, I can remember when it was common to see roofs sheathed with 3/8" plywood. Felt like you were on a trampoline when you walked across them.

Two days...and yes, 1/2 will work

You are looking at an additional $300 or so to go from 1/2" up to 5/8". The 1/2" with ply clips will work fine...but if money is no object, you may want to upgrade.

Roof

Here's the basic layout of my 1500 sq ft home's roof. I've been told it's about 36 squares.
Why is the amount of roofing more than double the square footage? Seems high to me. Just my 2 cents.

The roof area is always larger than the house size, because of exterior overhangs and roof pitch. The steeper the pitch, the larger the roof area.

That being said, it sounds like the difference between 1500 S.F. and 36 squares is definitely too high, unless someone is throwing in a huge waste factor. For example, using a simple gabled roof on a 50' x 30' (1500 S.F.) house with 2' overhangs, would require a pitch of 20-in-12. Not normally seen in this country (picture a 60-degree angle from the horizontal), and about 5 times steeper than a conventional 4-in-12 roof slope. Great for a house in serious snow country.

I'm not 100% sure if the garage is included in the 1500. I've been meaning to measure the house for years, lol.

Roof

What is the roof pitch? If steep, could affect time required to do the job.

I don't know.


I have to have 25 characters so this is filler material. I almost feel like a newscaster.

Its Houston, so I was assuming that it's pretty flat. 3:12 or so.

The work is moving along. Here's a pic:




I'm not overly happy with the process, but I guess that's why my customers, I'm in the cabling business, are willing to wait for me.

Holy Cow! You didn't say that they were replacing the rafters and adding on! Looks good so far!

Here's what we've ended up with after 11 days:









That's the good part, here's the other part. Trailers have been in my driveway for 11 days, our vehicles on the street, and no one has shown up today, so far:

Damaged 6-7 of these new star jasmine, but they'll grow back quickly.

Remember your check book is your most effective tool. Be nice, but point out your concerns to the boss [or at least who's in charge at the job]. Let them know you expect those issues to be taken care of before you make the final payment.
