Today, I will make an attempt to describe roofing warranties, and what they mean.
First, let's understand the relationship between the roofing contractor and the roofing material manufacturer. In order to be an "Approved Applicator" for almost all major roofing material manufacturers, you will be required to successfully complete three projects using their products.
The contractor is required to request inspections (startup, in progress, and completion). Assuming the projects are done according to specification and achieved a level of competence, you will then become an "Approved Applicator" of their material, and qualify for manufacturer warranties for your client.
All set? At this point, you are an Approved Applicator, and sign an Approved Applicator Agreement, and receive certification. Great Ron, why do you sign an "agreement"? The agreement stipulates the contractor is responsible for roof repairs (leaks) for a period of two years. After two years, the manufacturer becomes the "Guarantor" for the balance of the warranty.
Most roofing specifications are very clear when they demand a two year contractor's guarantee, and (varies) a twenty year manufacturer's warranty. It is not relevant if a contractor offers a 3,4,5, etc. year guarantee, as it is a moot point. It's a sales trickery thing, giving a false impression. Regardless of what the contractor says, he is only on the hook for two years.
I'll discuss warranty vs. guarantee, and their respective definitions another day. The only thing you need to understand here is who is the "Guarantor". Your contractor can be out of business tomorrow, so his guarantee would be worthless. I see it every day. Can I get a show of hands?
We'll talk briefly about types of warranties, and I am very serious about what I'm trying to impart here. All warranties are "Limited Warranties", and contain stipulations the owner must adhere to. The owner must maintain the roof system in a reasonable manner, and report any leaks within a 24-48 hour time frame, which is both reasonable and fair.
I'm sure a few people said NO to my limited warranty statement, and said "what about No Dollar Limit warranties"? Here is something I regard as gospel: NEVER install, or specify, a roof system that does not have a "No Dollar Limit" warranty, commonly referred to as an "NDL". It means the owner will not be out of pocket for roof repairs or replacement throughout the term of the warranty. PLEASE digest that. However, by definition, it is a "Limited Warranty".
The owner is not served by entry level (15 yr.) warranties. There is great VALUE in choosing a mid level roof system, and achieving a 20 year warranty. The upgrade allows the owner to keep many thousands of dollars in the bank for an additional 5 years. That can be a very significant sum of money, for a slight up front cost. NDL warranties are not prorated.
"NDL" warranties are offered by all major manufacturers, and in many cases are backed by surety's, or bonding companies. Top notch manufacturers like GAF, Firestone, Carlisle, DOW, Sarnafil, etc. have the financial resources to back up vast numbers of applications. I encourage you to take a moment to research the financial status, before enlisting a specialty, or "boutique" material manufacturer for obvious reasons.
The firms I mentioned above are representative, not exclusive, as there are many other firms too numerous to list in this space. Johns Manville is a fine company, and on it goes. I don't normally like to share personal observations, but I do not install roof systems that are not readily available from LOCAL SUPPLY HOUSES. This is important should you run short on material, and are holding up a job.
Tomorrow, I will discuss the relationship between all parties when installing a roof (architect, consultant, permit jurisdiction, etc.) and how it may apply to your specific project. It is critical all parties work in concert, and while that doesn't always happen, I can help reduce the grief.
I would like to introduce two dear friends of mine who are outstanding core individuals, and am proud to be associated with.
Mr. Laurence (Larry) P. Dickie, AIA, CP - Principal Consultant - Rimkus Consulting Group, Inc.
http://www.rimkus.com/ Tampa, Florida.
Larry and I have worked together for many years, and I've found him to be exceptionally skilled, and more importantly, a man of his word. Larry's handshake is as good as any contract as far as I'm concerned.
Ms. Janet C. (for Coral) Campbell, an extremely capable architect located in San Francisco, Calif. I enjoy an outrageous rapport with Janet, and we have open conversations on many topics. Janet is probably the top crusader in this country as it pertains to consumer fraud being perpetrated by unscrupulous roofing material manufacturers, and I'm proud of her. Very proud.
Please be enlightened by what she has to say, and ILLUSTRATE. It will arm you, and make you ask why? Hopefully, you will be motivated to ask your school district if they are involved in these practices. Find Janet at:
http//schoolroofingscam.blogspot.com/
Or, you can just type in Roofing Scam Targeting Schools, and you will be astonished.
I am overwhelmed by the many people who care what I have to say, and will do my very best to offer accurate, and useable information, to make your roofing experience more palatable.
How dry do you want to be today?
Keep looking "UP" my friends.
Respectfully,

"Overheated Prisoners @ DOC"
A theme in this blog is to apply roofing science to "real life" scenarios as it pertains to you as a taxpayer. Here, we try to solve problems and save money, while protecting the environment.
Sounds crazy doesn't it? Well, I think it can be done, and will prove how.
It gets very hot here in Florida, and I am trying to illustrate the value of "Cool Roofs" vs. petroleum based (mainly modified bitumen or built up roofing), and how it affects YOUR taxpayer dollars. You will probably grow tired of my constant comparisons, but I think it's something you need to know, and must know.

How hot is too hot on death row?
In a lawsuit, Florida inmates say lack of fans or air conditioners is cruel and unusual punishment.

Is lack of cool air in hot prisons cruel and unusual punishment?
Cast your vote.
Florida's summers are notoriously long and hot and humid, but apparently nowhere in the state are they longer or hotter or more humid than in a six-by-nine-foot cell on Death Row.
A federal judge in Jacksonville is being asked to consider whether the state's decision not to provide air conditioning - or even fans - in its prisons amounts to cruel and unusual punishment in violation of US constitutional safeguards.
It is an issue that arises most frequently in Southern states, where high summer temperatures can make prison life nearly unbearable.
There are no clearly established standards as to how much heat and humidity prisoners must endure before officials take special remedial action. Last summer, two inmates at the New Jersey State Prison in Trenton died of heat-related causes during a heat wave that boosted cell temperatures into the 100s.
The American Correctional Association suggests summertime temperatures inside prisons should range from 66 to 80 degrees F. But the vast majority of US prisons are not air conditioned and prison officials set their own standards.
The Florida lawsuit, filed on behalf of some 300 death-row inmates at the Union Correctional Institution southwest of Jacksonville, says the prison's own temperature logs demonstrate conditions that pose a danger to the health of the prisoners.
"During July and August, the recorded temperatures in the cell area during the day are almost always in excess of 90 degrees F, frequently exceed 100 degrees, and have been as high as 110 degrees," the suit says.
Two death-row inmates, Jim Chandler and William Kelley, complain in the suit that excessive heat has left them feeling sick and dizzy. They say prison rules bar them from affixing pieces of cloth and cardboard to their cell walls to deflect air from wall-based blowers toward their bunks. And they say that recent installation of metal security screening over their cell bars is further reducing the minimal air flow.
"We are not necessarily saying this building has to be air conditioned. We are just saying that air temperatures are too high and something needs to be done to correct that," says Randall Berg, a Miami lawyer who filed the suit on the inmates' behalf. "The state is housing inmates under conditions that are barbaric and causing them severe health problems."
Prison officials say that long hot summers are a fact of life in Florida. C.J. Drake, a spokesman for the Florida Department of Corrections, says that the two complaining inmates are longtime death-row residents, with Mr. Kelley arriving in 1984 and Mr. Chandler arriving in 1981.
"They haven't acclimated themselves to the heat after 16 and 19 years on death row?" Mr. Drake asks. "They are only now complaining about the heat?"
Drake says the lawsuit is based on inaccurate or incomplete temperature data and that prison officials are prepared to demonstrate in court that conditions at the prison are acceptable.
He says officials took temperature readings two weeks ago and found that when outside temperatures were 98 degrees, temperatures on Death Row were 86.9 degrees. Later that same day, officials recorded outside temperatures of 100.5 degrees and inside temperatures of 88.8 degrees.
Prison officials stress that inmates have access in their cells to water and that if they become ill from excessive heat they will be taken to the prison infirmary, which is air conditioned.
They add that there is no historical evidence of inmates suffering substantial medical problems related to excessive heat. "All they have is inmates complaining that it is too hot," Drake says.
Fred Markham knows a thing or two about prisons, having spent 27 years behind prison bars in Texas. Mr. Markham, who now works for Prison Legal News in Seattle, says Texas prisons are not air conditioned, but most provide fans. Even so, summers are difficult.
"You sit in the cell and you sweat, hour after hour," Markham says. "I've seen fistfights over who would get to sleep on the floor because the concrete was cooler."
"If you are locked in that cell for 23 hours a day it gets pretty ... intolerable because you are only showering every second or third day. So there are a lot of baths taken out of the toilet. I've done it thousands of times."
Markham says prison officials who keep their inmates cooler are likely to experience fewer problem inmates than those who let them broil. He says fans would be a welcome addition in most prisons, but "try to get a state legislature to kick down $1 million to buy fans for prisoners ... not in this universe."
Inmate-rights experts say prison officials are afforded wide discretion in running their facilities, such as setting budget priorities that may exclude air conditioning and even the purchase of fans.
But these specialists stress that prisons must provide a humane and safe atmosphere. If prison officials deliberately seek to use excessive heat as a form of additional punishment, they say, that could rise to the level of cruel and unusual punishment.
"Many prison officials and members of the public have lost sight of what an astonishing punishment the loss of liberty is," says Jamie Felner, a prisoner-rights specialist at Human Rights Watch in New York.
Many prisoner-rights experts stress that, at some point, most prisoners will be released and rejoin society. "If we don't do anything for them while they are in prison, they are just going to come out angry individuals," says Kara Gotsch of the American Civil Liberties Union's National Prison Project. "That is not the kind of person you want to live next to."
First, I would like us to set aside our differences, and not get drawn into what prisoners deserve, and what they don't deserve. We'll grow old debating, and sharing opinions on that, but this blog is based on science and fact, so we'll continue.
Why are the prisons hot in the first place? They're hot because the DOC specifies modified bitumen roofs, and many buildings do not ventilate well. As I've said before, these roofs greatly amplify ambient temperature readings. I'm going to get blue in the face, but YOU CANNOT INSTALL PETROLEUM BASED ROOFS IN THE VICIOUS FLORIDA SUN, AND NOT EXPECT THEM TO BE HOT!!!
The DOC's solution was not to do the very obvious by installing "Cool Roofs" for far less money than they spend on "Hot" roofs, but they are spending $750,000.oo dollars to teach inmates how to install....Ready?..........Solar Panels!
It is not uncommon for the DOC to direct purchase materials and have the inmates install them, but I can't tell you how many times I've been called in to clean up the mess of unskilled workmen. Friends, I've gone to prisons where the material was laying flat on the ground, melted, and completely ruined. The roofing portion was a criss cross of backward seams, laps, etc.
So, for that effort, YOU received:
1.) The material YOU purchased had to be removed from the site and deposited into a landfill.
2.) The roof YOU paid for had to be completely removed (a very difficult task), and deposited into a landfill.
3.) Purchase brand new material.
4.) Pay for a professional, licensed, contractor to do it correctly.
Now, I can't blame the inmates, because roofing with 450 degree asphalt, or a propane torch, in the Florida sun, might not be the best source of motivation. Did I mention each roll of modified weighs 100 lbs.?
I am working every day to change what I feel to be a barbaric, inhumane, and unsafe environment for humans to earn a living, or in this case "pass time". Countless millions of dollars are being wasted by increased energy demands we are CREATING, when it really doesn't have to be that way. This is what it looks like in real life, and I dare someone to say "foot traffic" or "redundancy of plies".

These workmen do not have ice water coursing through their veins, and I am offended by those who don't hesitate to put them in such a dangerous environment. You think that's a "cool roof" because it's white, don't you? That thing is so full of petroleum it's sickening, and ABSORBS heat, not REFLECT it.
If anyone from the DOC wishes to contact me, I would be more than happy to solve these problems. Because I can.
Enjoy your day, and keep looking "UP".Robert R. "Ron" Solomon

"Cool Roofs vs. Government Inaction""
We touched briefly on "Heat Island Effect", and heat absorbed by petroleum based roofing materials. This topic is so simple, yet so ignored, that I thought we could devote time today, as it is an ongoing theme.
To me (and I will further explain why), it is beyond irresponsible for any governmental agency, or department, on any level, not to understand this principle. Yet, I see the same outdated, "cookie cutter" roofing specifications, as I saw in the 70's. Who builds structures made of oil? Doesn't that just sound silly?
I decided to do a side by side comparison between a white reflective synthetic roof, and a white modified bitumen roof over R-20 insulation, and a warranty term of 30 years. The energy model (200,000 sq. ft.) revealed a carbon reduction of 77,000 lbs., and an amazing $456,000.00 in energy savings (Courtesy: Carlisle Syntec).
The example was to replicate the general size of a High School, so I could provide a visual. Folks, that's almost a half million of YOUR tax dollars spent without the slightest benefit. None. Now imagine the size of your school district, and multiply. Rather staggering isn't it? Now, repeat this process with prisons, universities, and all governmental structures. Keeping in mind the average energy savings of non-petroleum roofs is 20% (other factors also influence that number).
I am a conservative environmentalist (spotting one is like seeing the Abominable Snowman) seeking maximum benefit of taxpayer dollars, and pursue this with enthusiasm on your behalf.

I've never seen, nor heard of any roofer who does this, and frankly don't think it's their fault.
Where I am retired, independent of monetary influence or having to "go along" with the game, they are not. Please understand I have only friends in the commercial roofing discipline, and understand they have a common responsibility: To provide work, nourish their employees, so they can provide for their families. An incredible task for anyone in business, and I pray for their success.
They need WORK, and it would be cruel of me to criticize anyone for addressing commodities of immediate need. But, if government would get it's head out of the sand, my colleagues would just as easily comply. They cannot complain, or they will be ostracized. FACT.
Okay, that's enough of the shrill tone, but I would encourage anyone who gives a whit about tax dollars to ask your local, state, or federal government "why".
I've had the privilege of speaking to Dr. Steven Chu, Physicist, Nobel Laureate, Former Director Lawrence Berkely Laboratories, and now U.S. Secretary of Energy. Secretary Chu supports exactly what I'm saying here about white reflective roof systems.
Quoting Dr. Chu:
"Professor Steven Chu, the US Energy Secretary, said the unusual proposal would mean homes in hot countries would save energy and money on air conditioning by deflecting the sun's rays.

More pale surfaces could also slow global warming by reflecting heat into space rather than allowing it to be absorbed by dark surfaces where it is trapped by greenhouse gases and increases temperatures.
In a wide-ranging discussion at the three-day Nobel laureate Symposium in London, the Professor described climate change as a "crisis situation", and called for a whole host of measures to be introduced, from promoting energy efficiency to renewable energy such as wind, wave and solar.
The Nobel Prize-winning physicist said the US was not considering any large scale geo-engineering" projects where science is used to reverse global warming, but was in favor of "white roofs everywhere".

"Heat Island Effect" and asphalt shingles.
In this discussion, I will share the "Reality" of Heat Island Effect created by your asphalt shingle roof system.
MANY people are confused by, or have little knowledge regarding solar radiation, and the energy demand it creates. This is "Low Hanging Fruit" friends, so let's deal with that first.
The number ONE issue I face when discussing this topic is that all white roofs are "Cool Roofs". I speak to Professors, Architects, Engineers, and Government "Officials" who debate the esoteric, and ignore one of the most principle rules of physics: "Solar Radiation". Cool Roofs are almost exclusively measured by their ability to reflect solar radiation.
Please bear with me here, because I really need you to understand the following: Petroleum based roofing products (asphalt shingles, modified bitumen, and built up roofing) ABSORB the sun's energy, and retain it well into the evening.
But Ron, I've got white asphalt shingles on my home, so I've got a "Cool Roof", right? The answer is NO. The sun "sees" all petroleum products as "black", and your shingles may reach temperatures up to 100 degrees (assume all measurements to be Fahrenheit) hotter than ambient temperatore.
Example: If you change from a black asphalt shingle roof to a white asphalt shingle roof, you will not qualify for any energy rebates. The white granules embedded in asphalt shingles have very little reflective value. I don't care if the granules were made of chrome, your roof will be hot.
This energy absorption creates a roof surface temperature approaching 180 degrees, and greatly stresses attic insulation, and is a strong influence on your average energy consumption. For those of you who may be ambitious, try to touch them on a hot day. Now that's kind of like your Mother telling you not to touch the stove, but doing it anyway. Mom gets the Bactine, and you shout "blow it, it burns".
This is where you will say, "I live in a very cold climate", so why should I care? In your area, you may have more heating days than cooling days. So you would benefit from it, but most of the country (and world) do not live in that environment. I'll get into more regional discussions at a later date.
The best measure of a material's ability to reflect radiant energy is it's "Solar Reflectance Index" (SRI). Asphalt shingles rate very low at about .27, but I'll get into the SRI a bit later as I don't want to overload you with data. I will show you where to go, and you will see the published statistics. I do not feature EnergyStar in my assessments, as they allow manufacturers to publish their own statistics, and many times the manufacturer even owns the testing laboratory. How's that for a "Fun Fact"?
More on Heat Island Effect in the next post.
Have a happy, and productive day. Always remember to keep looking "UP".

Initial Introduction:
Here, we will be discussing the correlation between synthetic reflective roof systems, and their benefit to sustainability efforts. By benefit, I am referring to clean water runoff, substantial energy reduction, safety, and taxpayer/owner value. Reflective white synthetic roof membranes are inherently LEED compliant which I will address in detail with future posts.
Retired after 37 years in the commercial roofing discipline at the highest level, a licensed Roofing Consultant, and State Certified Roofing Contractor (Florida CCC1325620). I've been directly involved in the successful completion of over 70 public schools, and a great number of high profile commercial and industrial facilities.
I've had the great joy, and honor of being a nominee, a finalist, and judge (3 times) for the Governor's "Sustainable Florida" and "Sustainable Schools" programs, which are considered the premier sustainability achievements in my state.
The basis of my advocacy is to inform you, and let you make decisions based upon science, public record, extensive research, and your specific need. The idea is to separate the grain from the chaff, and maximize your roofing investment. Fair?
I do not sell anything, do not represent anyone other than myself, nor do I receive/accept monetary or personal advancement scenarios. This is the only way I can reasonably expect you to believe my statements to be free of influence. Along the way, I may share some experiences (good and bad) which you may identify with, or in some cases avoid altogether.
While these topics may be vast in terms of money involved, I do not take myself too seriously, and don't want to portray something I am not. I'll try to keep this page upbeat and positive, as that's my nature.
I will not participate in anything that is not inclusive of ALL people, as I find that beneath me, and frankly, beneath you. You will soon learn my aversion to "Proprietary Specifications", or "Sole Source" contracting, as nothing good ever happens there. Especially when it further burdens taxpayers.
Please know I am open to constructive criticism, and welcome comments based upon science or record. I'm aware I cannot be "all things to all people", and may offend someone with my directness, but I hope a direct approach is why you're here. I know many people who will tell you exactly what you want to hear, but I'm not interested in sacrificing my integrity to make it happen.
MANY of you will be interested in roof water catchment devices, material selection, and safety. Over 400,000 people in New Zealand alone depend on the roof as their only source of water, and we'll try hard to bring that into perspective.
By Oct. 18, I will post very specific questions, answers, concerns, and articles to get us started.
My goal is to earn your trust, and provide the information you seek.
"The positive thinker sees the invisible, feels the intangible, and achieves the impossible"
Thanks for spending time with me today, and don't forget to look "UP".
