Brief Estimate


So the set up. Have a 3 person crew, the 4th person is not always there and when there is on the phone (ie the boss). One person on the crew is experienced but hasn't roofed in quite awhile, the other 2 haven't at all.

17square ranch house with 2 valleys . Without woven valleys. Waste was approximately 2 tons. And no dumpster on site so all had to be hand tossed into a truck that couldn't be up against the building except in the drive way. So debris where every where.

One layer of shingle 2 layers of felt to come off and replace.

So I have 2 questions. How long should you expect a brand new crew to do this house? Both laying shingles and clean up? Experienced person and one inexperienced nailing and an inexperienced loading debris ?

The shingles were what I thought was three tab but I now believe to be architectural. The first load of debris was thrown into a flatbed with basically plywood sides and back, rudely 3 feet taller then the clean up person. The second load was loaded onto tarps and rolled into a pickup for easier dumping.

I'm asking because we all think my boss had an unrealistic plan on how long it would take to do it all. With a new crew
Thanks in advance.

If nessisary I can try to find a few pictures

Re: Brief Estimate


It's not uncommon for workers to think the boss has an unrealistic plan on how long it will take to complete a project.

As time goes on, he will have a better estimate of how much you can do in a certain amount of time.
Then the boss will still think you should have it done faster.

It doesn't matter how long I think it should take.

I recently hired a 6 man crew to tear off 4 roofs. I overestimated their abilities. They worked pretty hard all day long. They were just slow.
So, for the first roof, I had an unrealistic plan on how long it would take to do it all. For the next ones, I have a better understanding of their abilities. They will still go slower than I want them to, but at least I know what to expect.

1 gunner, 1materials, 1 clean as you go, plus materials. 2 days. This is all materials and clean up, the gunning is faster.

Re: Brief Estimate


Essentially you have one roofer (shingler) and a couple laborers.

Two days for the installation with the shingler and one helper. That would be a reasonable clip, but somewhat slow. For a shingler to throw down 2 sq an hour with a guy as a dedicated helper would be more in line. That's an average of 1 sq an hour per guy. Metal, starting, hip/ridge....I say give shingler and helper roughly 12 hours to do the whole roof.

As far as the tear off, there are a lot of factors, but having it all off of the roof and dried in in one day is a reasonable expectation. Two guys to clean it all up.....half a day. So you have 1 day x 4 guys, 1-1/2 days x 2 guys, 1/2 day x 2 guys....I don't really know how much value to put on the phone guy

Now reality is different. Working as unit, the tear off and clean up can be considerably shorter when the lead is actually leading and the laborers are following the directions given.

Just because one guy has a lot of experience as a shingler, doesn't qualify him (automatically) as a good manager of time and people.

Also job site prep, available tools (clean up and tear off) and disposal set up are huge factors. If there was "debris everywhere", it's not being done efficiently from the get-go. A ranch would have 95% of the debris moved directly from the roof into the dumpster/truck/bin. Once it hits the ground you have to fight gravity all over again.

Expectations and reality aside, it would be more useful to evaluate each crew member as to their potential....lead included.

Re: Brief Estimate


Yea, I figured it would have taken you guys close to 4 on the first one. After the first you will find it speeds way up. If the crew have no experience, and haven’t worked together before it is normal for the first one to take longer than expected. Once you guys are set up onsite and get into a groove it will improve. Sounds like your boss should have planned to spend some more time onsite on the first one to make sure the procedure was running efficiently. Amazing what a little more site time will do.

Re: Brief Estimate


Roof pitch can make a big difference, plus 2 story vs 1, but you didn't mention any of those. I also didn't include tear off.

Better to spend time on site the first day to cover the basics for being efficient, unless you aren't a hands on roofer.

Working by lights is way slow, no matter what lights you use.

Re: Brief Estimate


I can't imagine that 2 of us couldn't get it done in three days. Tear off 8.5 square for 2 days and shingle on the 3rd. We would probably get done early each day.

Carry everything over the roof and throw it in the truck. Don't throw it on the ground.

Re: Brief Estimate


Unfortunately one of the reasons the tear did not all go on one side of the house is because we were told to tare off front and they started shinglingin it. The back half of the home was not torn off until the next day, and all the remaining bundles of shingles had to be moved to finished portions to complete it.
