The Science and Technology
of Traditional and Modern
Roofing Systems

Dear Colleague:

You probably will not receive any notice during your professional career more important for decades to come than what you are reading right now!

Why? Because you cannot find any publication as of today to be of such immense completeness and filled with the culmination of worldwide acquired knowledge in the field of roofs, roofing and waterproofing. It provides answers to any questions you might have and opens doors for you to further explore any published literature on the subject, all in a condensed roofing library consisting of a 3,152 page, two-volume set (80 chapters) on one CD-ROM & E-Book in full color, where all the information is easily searched in a matter of minutes.

Also Available by the chapter!

This book set is already accepted as "The Bible of Roofing" by professionals and students on a global scale, and Dr. Laaly has won the World Lifetime Achievement Award from the American Biographical Institute. If you have contributed to the advancement of roofing science and technology (in the form of Research Data or Scientific Publications), your work probably has been acknowledged and highlighted in this masterpiece. If you have developed any roofing materials, components, tools or equipment, or have enhanced existing products, your company's name, address and telephone number(s) have been mentioned in this text in the appropriate sections.

My two-volume set on CD-ROM & E-Book, will provide you with the most up-to-date, in-depth and complete information by the leaders in roofing science. Achievements in roofing materials, accessories, system design, services, organizations, standards, testing, and performance criteria are systematically discussed - more so than any other publication of its kind.

It is a pleasure to share with you the results of many years of hard work - lifetimes of dedication of thousands of individuals and institutions made available for you.

I'm sure you will find the possession and daily use of this two-volume set on CD-ROM & E-book most rewarding - possibly the best investment your company or institution can make to function more effectively in the ever-changing world of roofing practice, science, and technology.

With sincere personal regards,
