The Problem Isn't You. It's How They Explained It to You.

It's 10 p.m. at the kitchen table. The practice question asks which underlayment goes where and how far the laps run, and you've rolled out more of it than you can count, but the answer won't come.

The manual gives it to you in paragraphs: ASTM numbers, lap widths and offsets packed into the same long sentence. Nothing on that page looks like the roll you carry up the ladder.

Felt D226/D4869, synthetic D8257, self-adhered D1970: 2 in laps, 4 in end laps, 6 ft offset

In the book, underlayment gets one page. Felt, synthetic and self-adhered are drawn side by side on the deck, each with its ASTM number, and the 2-inch side laps, 4-inch end laps and 6-foot offset are marked right on the drawing.

Pitch, squares and bundles, step flashing, the ¼-inch drainage rule, attic ventilation: each one has its own page, drawn the same way.

You see it, it makes sense, and you answer in the exam's own words, or you know exactly which section to look up if your exam is open book.

COMPARE FOR YOURSELF

Same Topic, Two Ways to Study It

THIS
  • The manual: line after line
  • Pitch and slope explained only in words
  • You walk into the exam with doubts
Roof slope, referred to as pitch in field practice, shall be expressed as the ratio of vertical rise to horizontal run, wherein the run is standardized at twelve inches. Accordingly, a designation of 4:12 indicates that the roof surface ascends four inches for every twelve inches of horizontal projection. Said measurement may be obtained from the exterior roof surface or from the underside of the rafters within the attic space, provided the level is held true and the run is measured horizontally and not along the rafter.
FOR THIS
  • Pitch in one drawing
  • The numbers in one box
  • You see it and it makes sense
2,350 sq ft → 23.5 squares → 71 bundles before waste

One Page, One Topic, All Clear

Think of it this way:

You're tying a roof into a sidewall, or it's the exam question about it: how big does each piece of step flashing have to be, and what goes over it? You've done it a thousand times, but now you need the number.

In the book you open the step flashing page and see the wall drawn in section: one 4 × 4-inch piece per course, each shingle laid over it, the siding lapped over the top, with the IRC section flagged to check against your edition.

Step flashing: minimum 4 × 4 in, one piece per course, siding over it (IRC R905.2.8.3, check your edition).

Same with pitch and squares, underlayment laps, the ¼-inch drainage rule, metal panel slopes and attic ventilation: each one on its own page.

Roofing Contractor Illustrated is 9 parts and 62 topics, all drawn, and it ends with the numbers page, the mix-ups that cost points and a last-week review plan.

What you see drawn, you don't have to memorize.

Frequently Asked Questions

Is it for me if I've been roofing for years and haven't taken a test in decades?

Yes. It doesn't teach you to roof from scratch: it starts from the roof you already know and puts each topic in the words and numbers the exam asks for, one drawn page at a time.

Does it work for my state's exam?

It's built on the codes most state roofing exams draw from: the International Residential Code (Chapters 8 and 9), IBC Chapter 15 and OSHA 29 CFR 1926 Subparts M and X, plus candidate bulletins from boards like California CSLB (C-39), Florida DBPR, Arizona ROC and Nevada NSCB. Code values are flagged on each page so you can check them against the edition your state enforces.

Is this official material?

No. It's an independent illustrated study guide. It isn't published or endorsed by any state license board, the ICC or OSHA, and it doesn't come with a certificate or count as course hours: your license comes from passing your state's exam.

Does it replace a prep course or the code book?

No. It covers the trade part of the exam: the roof, the code values and job-site safety. The business and law test (California's Law and Business, Florida's Business and Finance, Arizona's business management exam) isn't in this book. For that part, and for the reference books if your exam is open book, use the list your state board publishes.

Are the practice questions the ones on the exam?

No. They're written for this book, in the style of a trade exam, and each answer points you back to the page that explains it.

When and how do I get it?

The book and the 2 bonus books come as a PDF by email, sent to the address you enter at checkout.

Do I have to pay every month?

No. It's a one-time payment. No subscription.

Can I get it on paper?

It's a PDF, ready to print. Print it at home or at any print shop and keep it in the truck.

How does the refund work?

You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.

Before You Close This Page
