Shingle Estimating Chart


I was given a sheet of paper today with the following roofing information,

task-----------------time required x amount---------------------total time
tear off-------------1 hr / square

install
felt paper---------30min / square

apply shingles
flat run------------2 hrs / square
ridges, hips-----30 min. /10 ft
dormers----------add 1 hr each

flashing,
chimneys-------2 hrs, each
vent pipes -----30 min. each
valleys----------30 min, 10ft
roof vents------30 min, each
skylights-------2 hrs, each
drip edge------30 min, 20 min

My question is, I wanted opinions on whether this is good advice or should it be filed in the circular file, otherwise known as the trash can?

Re: Shingle Estimating Chart


trash it,it's way off.2 hours flat run for a square.an hour for a dormer?

too many variables to put a certain time limit on most of the list.I charge by making a visual inspection,measuring,and knowing what we are capable of on a bad day.

Re: Shingle Estimating Chart


I agree with wiz. While shingles are a commodity and are sold by the square, the same cannot be said of the resources needed to properly install a good roofing system.

Each roof is a custom built system. To try to boil it all down to a common denominator (sq. ft.) does a disservice to the consumer and the trade.

We build our quotes based on (among other considerations) how many man hours we believe the job will take, the technical requirements of the job, the height and steepness of the roof, project accessability (petunias in the landscaping need protecting?) and how much common sense the homeowner has (some would deny that gravity has any impact on the tear off process).

For instance: The tear off on this information is rated at 1 sq/hr. Soooo. . . is this reflective of the need to strip off one layer of shingles? Two layers of shingles? How about 3 layers? And are these shingles six nailed? Are these asphalt composition shingles or wood shakes? Is this on a 4 pitch roof or a 14 pitch roof? Is the roof deck 7/16" OSB? 1/2" Plywood? 3/4" plywood? 1" x 8" dimensional hardwood? Pine?

All of these variables impact productivity. In short, this piece of information you have is not very useful.

Some years ago, a general contractor who should have known better secured a contract to install wood shingles on an apartment complex in Florida. His prices came from Means, and were based on "average" rates for wood shingle installation in the area. He reasoned that his inexperienced crew could work at least half as fast as the professionals, and bid accordingly.

If anyone has watched a skilled wood shingler at work (the nail guys, not the rookies with staple guns), they can fully appreciate the consequences. The GC discovered (much to his horror) that the "one square per hour" installation rate was for serious professional roofers. The rate for his crew (including himself) was about 2 squares a day, and that was on a good day.

I have not seriously considered generic estimate sheets since witnessing that debacle in Florida.

Re: Shingle Estimating Chart


I'm all for learning and try to learn something new every day.

I'd hang it on the wall/bulletin board, then I'd see how my job pricing and time taken compared. A lot of variables.

40 degrees, I can T.O. 2-3, or more single layer sq. off, per hour.
90 degrees, I HOPE to get 1 an hour.
I base my time on 'Off, swept, and in the truck or dumpster. Add another few minutes to re-nail that area of deck and rid it of any loosened nails.

Holy Steep Roof, Tin Man!!!

You work on a 90* pitch?

That is a vertical wall. What do you do, stick your pitch fork into the shingles at the top, secure yourself to a bungee cord, and go bouncing up and down till it's stripped off?

Re: Shingle Estimating Chart


If it's just the top piece I probably would, as 'favour' to the customer, and make sure he realised that. If it involved replacing the whole thing I probably wouldn't. The flashings, of course all get changed out, anyhow.

It's often easier to take the top section of a metal chimney off to replace the flashing.

Re: Shingle Estimating Chart


Does my contract say I will replace a furnance pipe? If not I will have to charge them, and I will do it, but would prefer not to. I will however make sure it is 100% water tight where the pipe meets the roof. I'd probably try to upsell the square housing unit that is supposed to look like a brick chimney but really only does if you are driving past 20+ miles an hour.

Re: Shingle Estimating Chart


I meant just the top piece i guess. Meaning from the shingles up. Its seems like where i live when a neighbor gets a new roof the roofer always puts a shinny new furnace vent on.

Ps Had a neighbor get a new roof. ASk what kind of shingles he said iko 30 year i didn't say anything.

It's really a HVAC thing, a vent pipe which vents dangerous exhaust gasses. I personally am not comfortable doing it myself, even though it is pretty simple. I don't know of any roofers that do this on a regular basis as part of their base package.

Again if it's in my proposal form, I am doing it and if it's not in the form it'll cost extra.

Re: Shingle Estimating Chart


Even on insurance jobs unless damaged from a tree or something the only thing the insurance will pay for is replacing the cap if it has hail damage which most do.

$42 for 5in
$48 for 6in
$54 for 8in

Add $157 base charge for the heating work, which every insurance company pays but Allstate. Now's a good time to tell all that Allstate is bad, really bad.

A couple weeks ago the home owners wife asked my father if he put a new cap on the heating vent. He said he replaced the cap and painted the whole vent to match the roof, she was happy.

Above prices are via Xactimate Minneapolis version, best $1,600 I've ever spent on my business. The average jobs yeilds a minumal of $1,000 more than the adjuster figured and up to $4,000 more on single family's (roof only).

$1,600? Wow I heard ALOT more than that... and monthly update fees?

My price is typically always higher than the insurance is willing to pay.

Re: Shingle Estimating Chart


If you have a signed agreement for replacing with similar like materials, then they MUST pay the going rate you charged so the HO does not have to reach any deeper than his/her deductible.

Getting them to sign before it is approved is the trick.
