Roofing Systems Compared
The roof takes the worst weather.
Yours should be ready for it.
Compare the ways buildings keep the sky out and learn to choose, detail and defend the right roof for any project without second-guessing yourself.
Roof choices will become quick, confident calls for you.
- Know every option — understand flat, pitched and green systems and where each belongs
- Pick with certainty — choose the right roof for climate, form and budget
- Detail the edges — handle parapets, gutters and penetrations where roofs fail
- Plan for drainage — move water off a building deliberately, never hopefully
- Think whole life — weigh maintenance and longevity before problems get expensive
- Answer hard questions — justify your roofing decisions to clients and consultants calmly

If you see yourself here, start today.
A few hours from now, you could already see differently.
Roof build-ups all looked the same to me on paper. Comparing warm, cold and inverted systems with their real failure modes finally made the differences meaningful. I specified my first roof assembly independently last month and the senior architect signed it off without changes.

Answered simply.
Will this help me choose between flat and pitched systems on real projects?
Yes — you'll compare systems by performance, cost logic and failure modes, so your recommendation comes with reasons rather than habit.
I'm an intern who's never detailed a roof — too early for this?
It's the perfect moment. Roofs are where interns first get exposed on real drawings, and arriving prepared changes how you're trusted.
Do I need any prior experience?
No. Every course starts from where you are and builds up step by step, in plain language.
Is this software training?
No — software changes yearly. The thinking you learn here lasts a career.
How does it work?
Short video lessons with a small practice task after each. Any device, your pace.
What does membership include?
One membership unlocks every course on RTF Academy — all 450+, nothing sold separately. And you stay in control: cancel anytime in one click, and you will never be charged again.
