How to Prepare for the ICC F15 Shingle Roofing (2015 IBC/IRC) Exam

Start with the books. This is an open-book exam, so the references on the bulletin's list are your main study tool. Get the editions the bulletin names.

Learn where things are. Read the table of contents and the index of each book until you know where every major subject lives. On test day, finding an answer fast matters more than memorizing it.

Highlight the sections you use most. Check the bulletin's rules on tabs and markings before you add any.

Spend most of your time on the biggest topics. Fasteners, Flashings, Scuppers, Etc. and Re-roofing make up 59% of the exam.

Take timed practice exams. The clock trains you to find answers at the pace the real exam needs: about 3 minutes per question.

Aim to pass more than once. One passing score can be luck. Several in a row means you're ready.

On Test Day

• Then go back to your bookmarks and work them out.
• Don't let one question eat your time. You have 2 hours for 40 questions, which is about 3 minutes per question.
• Before you finish, answer anything you skipped. A blank can't earn a point.

Study Tips

Only select answers that directly respond to the question asked—not ones that merely sound correct or seem true. After choosing, verify your answer against the question to confirm you didn't misread it and that your selection genuinely addresses what was asked.

Our practice exam is specifically designed to mimic the testing conditions at all exam centers. While untimed PDF study guides might help with studying, they don’t prepare you for the challenge of managing your time during an actual test.

Before reading the answer choices, try to predict the correct answer based solely on the question. Your thinking is sharpest at this moment, before distractors cloud your judgment. Then scan the choices for your prediction—if it's there, you're likely right. A quick check of the remaining options is still worthwhile, but trust your instinct.

On an open-book exam, work through every question once: answer the ones you know and skip the ones you don't. Then go back to the ones you flagged. You can bookmark questions for later review, just like on our exams — and don't sink too much time into any single question. The clock is still running.
