Trailor To Dumpster. Now What?

mattp

I just close a 80sq church job. 50sq is 3 layer asphalt and the other 30sq is one layer asphalt. All tear off is 20-25 yr 3 tab shingles. I always use my dump trailor but this time Ill be setting dumpsters on the job. So my question is how many squares can the large containers hold (sorry its sunday and cant call the dump to get the dimionsions of the container till tomorrow)? Or how many containers will i need? By the way 2 other contractors bid the job and I was $6,000 higher and still landed this thing.

Figure the information you need by the weight being removed and how much each container can hold.

I can easily do a 35 - 40 square one layer re-roof with a 20 yard.

You have 180 squares total of shingles and you can safely fit 40 squares in a 20 yard dumpster without going overweight, so you would technically need 4 1/2 dumpsters.

I would try to see if I could fit the first 1/3rd, or 60 squares into the first 20 yard container, only if they are so degraded and have already lost a significant portion of their granule surfacing and asphalt saturation weight. this way, you would only wind up paying for 3 of the 20 yarders, unless they charge you an extra fee for the overloaded tonnage.

Otherwise, 4 will do the job without much concern.

I usually get abouit 40 sq in a 10yd dumpster---80 sq. in a 20 yd dumpster

I have also been able to put 70 sq. in my 14.5 yd trailer. Very heavy.

I like the 40 yard dumpsters. The sides are high enough (about 8') that it makes it much more difficult for others to fill your dumpster. Anything in a public location overnight seems to fill up with the neighborhood junk.

The pricing (at least around here) is not proportional to the size. A 40 yard dumpster will cost me about 1/3 more than a 20 yard one.

Ask the hauler about weight.

Ed the Roofer

In my area and others that I have read about, the dumpster companies will not pick up asphalt roofing materials in anything larger than a 20 yard dumpster.

So, be sure to check if they can carry the additional weight in a larger container, which will save significantly on the refuse disposal costs.

Your going to average 1 ton for every 8 squares of roofing material you have as tear off. The roll off company is going to charge you a flat rate for what ever size roll off you request. This will include up to X amount of tons, once the roll off weight exceeds the specified tons you'll get additional charges per ton that it's over the limit.

According to your numbers you will have about 23 tons of material which will probably be 3 20 yard containers, so ask for two containers to be delivered at the same time. When the first one is full call for pull off and replacement. Then you should be good to go to finish tearing off and leave some room for the waste and final clean up.

Hope this helps

I agree with the 3 20 yarders.
I slightly disagree with the tonage.
I predict 20 tons max.
Matt, please get back with us on the exact number....

mattp

Thanks for all the help guys. This job is about 2 weeks out and will prob take me and my two helpers 2 weeks to complete. After I get all the dump tickets I'll let you guys know the exact numbers. I think I'll go the 2 at a time route and have a third one set when the first one is picked up (if needed). I called the dump today and I can fill 30 yd containers with shingles. If anybody wants to compare costs the charge $188 to set the container, $311 to pick it up, and $43.72 per ton of debris. Thanks again for all the help.

I don't understand. Why do want containers if you own a trailor?

I would use the trailor because you can move it around the job site so much easier. Plus you won't tear up their parking lot

I have 180 total square of shingles to haul off. My trailor will hold 40sq max so thats a total of 5 trips to the dump. The closest dump is 60 miles round trip. With the dumpsters I can have 2 set in the parking lot and dump there and save hours of driving time. I will be renting an aerial fork lift for materials to be handled. I will also build a box out of 4x8 plywood and attach it to the forks raise it up to the roof fill it with trash then dump it in the container. So unless Im missing something that has to be the easiest way.

I predict 22 tons . Don't forget felt (1200 pounds) and waste from the new roof and nails. The smaller the box the less weight allowance of course and the likelihood you would go overweight per box. $499 seems kinda high for pull and drop alone. theres gotta be a tonnage included in there. Get as large a box as you can fit on site to keep the drop and pull costs down. Im thinking two thirties should do it. Cant even get forties here. And its about $85 a ton over a typical 4000# to 7000# limit depending on what county here in NJ and the pulls about $200-$350, Ive gone over weight with a 20 yard box with a small slate tear off that didn't even fill the box 1/4 way up.

I just bid on a 370sq laminate tear off and will not be wasting money on renting dumpsters. Instead if I get the job I will bring both 14 yard dump trailers to the site and run back and forth to the dump which is only 10 miles away.

One building is 240 squares and the other is 130 squares, four sided 5/12, both insurance.

Will plan to load about 50 squares into the trailer and will have to make as many as 7 trips but it will be under $500 in dump fee's. Renting dumpsters would run around $2,500. With the dump trailers I will be able to back them right up were they are needed as they are needed. In addition won't have to worry about the heavy steel dumpster wheels wrecking the black top.

Now just to secure the job!!!

dougger222

One big problem too right now in Minnesota with large dumpsters is road restrictions. It's hard enough having to sneak the boom trucks in!!!

mattp

Wow you can dump 370 sqs for under $500. If I were to use my trailers dump fees alone would be around $1,500.00.

Seems ive been out of the dumpster loop for awhile. Just got a quote for a twenty with 6500 lbs of roofing $580.00 plus $90 a ton for overages. That would be a roll off. I used to use this guy because he was one of the last to use skips. Which were nice for a couple of reasons. They were small and tall. and cheap. They take up less room than a sub compact car. They don't drag them on the pavement like a roll off. they use a chain sling. Unfortunately he no longer has this setup anymore.


So its costing me roughly $40 a square for a two layer tear off that I can guarantee im not going to get.

Yes your streets are crazy narrow over there. And space is limited. I cant imagine anyone over there trying to fit a dumpster as long as a bus on a residential block. Which reminds me. Years ago my uncle in law begged me to use his sanitation company for a very large retirement community re-roofing project he landed for me. I only needed a single 10 yard dumpster for the cap tear offs and cut off scraps. But there were an awful lot of roofs. That single roll off dumpster wasn't there one day before I got a rash of complaints from the association and its residents. (old retired people have nothing better to do but complain) Had to have him pull the roll off and I went back to my skip guy.

I used to see the roll on roll off skips on building site but if your doing a residental re-roof then the smaller skips the way to go.
Lol@ cray narrow , but your right!
