Roof pitch

Roof pitch is how steep a roof is.

Waterproofing and Building Envelope

Why it matters

Pitch affects what roofing materials are appropriate and how well water sheds.

Where people get this wrong

Some materials require minimum pitch to avoid leaks. Low slope roofs need different details than steep roofs.

Real-world example

A roof looks like shingles, but it is too low-slope for standard shingle details. Leaks show up because water moves slower and finds seams.

Where this hits your build

This affects how your home handles water. Water damage is one of the most expensive problems to fix, and it often starts with details that seem small.

Most people do not just struggle with terms. They struggle with the decisions tied to them.
