Re: Satellite Roof Measuring


Some vendors have been much easier to deal with and that will be something to consider when I make my final analysis, which I must remind you all, will wind up being an evolving referral list, since this technology is becoming so prevalent and with more and more of them entering the field of competition, the price levels will automatically come down, as newer software tweaks are made to render the useage to becoming completely SAAS available, with no other human intervention from the company offering the product.

Some vendors of various other types of products that I have thoroughly tested and reported on have alerted me that their sales and recognition has risen dramatically, precisely due to the commentaries I have made and referred to them.

I forsee that someday soon, an organization that I know about, that is in the beta development stage, will have access to all of the proven products on the market, with substantial group discouts available, due to the sheer volume of appropriate demographically selected contractor candidates available to utilize the resources affiliated with the group.



Here are a few of the MANY services that I have handy to list here right now for others to compare also.

There are about 40-50 other sites that I did not list yet.

Does anyone have any sites to add to my list for any of the categories?

Re: Satellite Roof Measuring


A representative from Roofer411 will be attempting to contact Ed to offer the sample reports for comparision.

The main thing about Roofers411 is that it is a company built by roofers for roofers. We are not trying to cater to large insurance companies or even super large commercial roofers. Our reports are personally generated, not automatically generated by some elaborate software. We account for pitch! - you don't have to know that already to use us. Those working for us did not apply...they were hand selected, all having roofing experinece.

Re: Satellite Roof Measuring


Since my PM box is full and I won't be sorting through them and deleting any until this coming weekend, my e-mail address is eddiesdad@sbcglobal.net.

I know of another company out there, but you have to be a member of their organization that gets insurance leads, that supplies the views for $5.00 each.

I figure a good price point for this type of service once it is automated or allows for the authorized user to take control of the measuring features, would initially be around $20.00 and eventually working it's way backwards down to around $10.00 each, due to Economy Of Volume.

Re: Satellite Roof Measuring


Skyscope's new website is skyscopeinternational dot com (no URL's with under 15 posts)
There is one other paid service we know of called Connect Point, their website is assurecalc dot com

I'm not spamming, I'm here to answer questions. I'm not an EagleView salesperson. I've been working for EagleView for over a year, I started off with Dave Carlson (our founder who is a 2nd generation roofer) as a measuring technician. That's right we manually measure every single report that is ordered. Additionally each report is reviewed again by our most experienced techs for quality assurance. We work very hard to provide you with the most accurate report possible.

Correct, as you can see I've never posted in this forum before. I'm just trying to reach out to our potential (and current) client base to answer questions and look for suggestions.

The last point I would like to make is that we are not like some of these other companies who come on these forums posing as roofers "who use this or that measuring service". I'm coming to you up front and honestly. I'm here for your feedback, because the fact is we can't get any better, unless we know what your looking for. If you can respect that and you're interested to hear more let me know with your questions and concerns. If you'd rather the vendors stay out of the discussions that's fine. Let me know and I'll quietly pipe down.

Re: Satellite Roof Measuring


Thats interesting, they have Skyscope USA plastered all over their site.

On the other hand they also claim to use a system "designed" from EagleView so who knows.

Re: Satellite Roof Measuring


Well, that is not for me to judge, just report from credible sources.

It would seem as if there will be many trademark, copyright and patent objections to be made in this new technological industry.

It would seem familiar to the objection that EagleView's Legal Representatives made against a party from Texas mid last summer, regarding the outsourcing site that some one made innuendo about trying to Reverse Engineer the EagleView model.

Re: Satellite Roof Measuring


While I have not been using a paid satellite service for takeoffs, I have been using google earth in conjunction with roofcad...with mixed results. I can't imagine the other satellites fare much differently.

The number one issue with satellite imagery...TREES...aparently satellites cannot see through them very well.

The other issue I find is clarity...maybe cuz Google is free .

I find if the roof has brown shingles for example, it tends to blend in with the brown grass fairly well (not much green grass anymore hah), making it very difficult to determine where the roof ends.

Most residential stuff here is a typically a single storey bungalow with detached garage. I find you have to be reasonably lucky to get the thing bang on, which, if you are quoting single car garages and bungalows, you need to be.

Now when it comes to large scale, high roofs, this also works fairly well. With steep stuff I am still somewhat reserved however, the multiplier they (roofcad) use seems to be somewhat general the steeper it gets, which in turn has a large effect on final quantity. I can't imagine a lot of these satellite apps fare a lot better with steeper stuff...it's the nature of the beast I think.

The other thing with roofcad is I can't seem to find where it will break out different areas, it just gives me one lump sum (for all pitches) area.


I think in the long haul this thing will work well, but it's going to take some time (being the one guy that has to do everything leaves little time to hone things), but should prove very valuable I think with some of the larger highrise and condominium reroof stuff we do. I'd much rather get my measurements via point and click than tape measure, now that I've been doing it for awhile, but I think in the meantime, the single family dwellings will recieve the full meaure

Re: Satellite Roof Measuring


MrRoofer,

It's true measuring houses isn't always easy. A number of things can get in the way (trees, blurry images, etc) but we've been measuring roofs by aerial images for quite some time now, and we're very accurate. In some cases we won't measure the roofs if there is too much tree coverage, because then we can't verify our accuracy and that's one of our biggest selling points.

We actually use 5 different images to calculate the area of a given roof. The "top down" image and 4 oblique views (N,S,E,W). With the oblique views we accurately determine the pitch and the total square is calculated with the pitch accounted for. We've been mastering our process for over two years now (open for business just over one year), and we pretty much have it down to a science. Almost all of our reports are accurate within 0-3% of total square footage (waste not included), and we guarantee a report will never be off by more than 5% or we will not charge you for the report. Insurance companies trust us (and many use us), and giving most adjusters an "EagleView" ends any disputes over total square.

We're 3rd party tested and approved, we're unbiased, and we're extremely accurate. Sorry I know this sounds like a sales pitch but it's the truth and I believe fully in our product. Look I know a lot of you guys out there use some of these web tools to measure your roofs and that's fine. I'm not hear to change your mind. I just want to share information with those of you who don't always have to get to all your estimates, who would like to provide a more accurate and more professional presentation to the homeowner to close more sales, and who don't want to argue with Independant Adjusters anymore over how much material you used to cover a roof.

So MrRoofer if your interested I'd be willing to measure a roof for you to show you just how accurate and professional our reports really are. Just shoot me an email will.hieronymus @ eagleview.com

Thanks for listening to me ramble

-Will

Re: Satellite Roof Measuring


Hey Will, thanks for your response, I will have to take you up on your offer at some point, right now with the snow melted, spring is insane, so I will have to get back to you! I can think of a number of applications for us that this service would indeed be the best approach...how are your pilots at finding random ski huts in remote mountain areas?? Satellite images from 1 1/2 km away are entirely uselsess as opposed to the 25m shots we get in city.


I think it has to be pointed out there is a big difference here between the satellite and aerial methodolgy in discussion here with the various different measuring systems available. I would tend to agree even without a full on sample test having perused your site your system should be fairly accurate.

Personally we chose RoofCAD not because it provides us measurements (a site visit is required for your own 'scale') but because of the flexibility of the program itself. I am learning complicated satellite images are not really it's best use, far from it (however, having budgeted the software into our first project's profit margin, it has already paid for itself, and from here on out all satellite measurements are free). It offers the ability to not only produce takeoffs from satellite, but also allows us to punch in our own site measurements rendering takeoffs and our own set of colourful roofplans (subs like pretty pictures it seems), and lastly we can render takeoffs from the roll up digitizer, digitally reproducing blueprints in seconds and generating a takeoff at the same time. There is certainly a learning curve that goes with it, and we have yet to fully realize and work into its full potential to our operation, but it will come in time (which with a small staff we are in short supply!)

Plus it is Canadian .

Doug at rooflogic has been very helpful and accomodating, even with the dumbest of questions (honestly I would probably tear my hair out being the help support guy for unrully computer illiterate roofer types ). No I don't work for them, but I do believe that what they have is a great tool. Kinda like the Hitachi NV45AB2, if you knowhatImean. I don't have a problem sharing my thoughts on it either, as long as people are aware it is my opinion, biased as it may be.

Re: Satellite Roof Measuring


Looks like this field is expanding & spreading out - I just got an email from www. goilawn .com targeting landscapers & lawn maintenance (lose the space if you wish to visit)

Now if we can get a company that does siding measurments & setback diagrams

You can use www.iPhotoMeasure.com for on site photos to download and do the measurements on your computer at your office later on.

Re: Satellite Roof Measuring


I have recently trialed RoofCAD & the Digitizer from the RoofLogic people. First impressions were very good, although there is this annoying flicker of the diagram when you zoom/reposition it (not sure what version the trial was and if it has been fixed in the latest version that came out this month). Outside of that, the software is actually pretty damn phenomenal.

The Digitizer software, which MrRoofer mentioned above, is seperate from RoofCAD. Both can be used seperately or together. Digitizer is the component to easily create diagrams from satellite/aerial photos, paper/electronic plans. RoofCAD is used for free-handing it and inserting descriptive labels, images, and annotations to the diagram. Both components generate take-off reports.

One thing I am looking forward to by RoofLogic is their addition of Mobile GPS to their modules. This will allow you to interact with your RoofCAD drawings while on the roof. Imagine measuring two points on the roof with your handheld device and auto-rescale the entire drawing, or plot objects (skylights, drains, vents, etc.) with ease.

RoofCAD is not too pricey, while the Digitizer commands a $2000 tag. The software can be subscribed to on a monthly basis now for a reasonable charge (see roofcad.com for more info). They did this in acknowledgement of the economic situation we are in.

I do believe many, if not all, services such as EagleView, Roofers411, GeoEstimator, etc use Pictometry service software in combination with their own CAD software (like RoofCAD) to generate the reports. Without Pictometry, they cannot get the heights/lengths required to make the slope measurements.

In general, satellite imagery is not there yet, unless you have a dedicated spy satellite. Any online service worth their salt will be using the Pictometry aerial photos which offer 40 degree angle views from the N,E,W,S as well as the overhead view. The aerial photos offer more detail per pixel and fairly accurate measurements on the whole (+/- 3% ???).

Still, even with a regular GoogleEarth satellite image, one could get the proportional aspects of the diagram correct enough. You can add in any identifiable components and take the rough sketch when you make your call. After visiting the roof, one only need to take one edge measurement and the entire drawing can be automatically rescaled with just one click.

Re: Satellite Roof Measuring


Hey Matt, I would agree that the "services" are probably the right solution for a majority of the contractors out there. One reason we were looking at RoofCAD, however, was for other modules in the RoofLogic suite of apps (such as the Asset Manager). I was pleasingly surprised by its ease of use.

What I meant to say is that the public satellite detail is not there yet. Spy satellites are of higher resolution. And, if you believe everything you see on 24 and what they are capable of, they can read license plate numbers off of vehicles travelling at 60 mph.

I probably should of used the term 'aspect ratio' as opposed to 'proportional'. If a roof is 3 units wide by 2.8 units long ... one only need measure one eave of the roof to determine the actual scale.

Services such as GoogleEarth use a variety of sources to produce their image data. Each image from a single source (some aerial, some satellite) may not be of the same resolution or distance, thereby making standard measurements more difficult to ascertain across the field. Accuracy cannot be guaranteed.

Pictometry is unique, in that, they own their own fleet of 50 Cessna's that continually cruise the skies at certain altitudes using the same cameras and measurement techniques, thereby giving them an efficient method of determining more precise measurements.

In my opinion, I think mistakenly stating that satellites are responsible for remote rooftop measurements is not entirely true. It is important for the consumer of the services to understand the differences between the two, for accuracy sake.
