Lesson 4 • Drainage System Overview
Introduces gutters, downspouts, and flashings as an integrated drainage system. Students understand how each component contributes to whole-roof water management.
Chapter 2HideHide detailsSee detailsGutter Materials and System Types
Gutter Materials and System Types
Lesson 1 • Sectional vs. Seamless Gutter Systems
Contrasts sectional and seamless gutter construction methods, joint risks, and installation requirements. Students evaluate which system suits each project scope.
Lesson 2 • Gutter Material Properties
Analyzes aluminum, steel, copper, vinyl, and zinc gutter materials by durability, cost, and climate suitability. Guides material selection for long-term performance.
Lesson 3 • Gutter Guards and Leaf Protection
Reviews screen, micro-mesh, reverse-curve, and foam insert guard types. Students assess guard effectiveness and maintenance implications for each system.
Lesson 4 • Commercial and High-Capacity Systems
Introduces box gutters, scuppers, and internal drain systems used on low-slope commercial roofs. Connects commercial drainage design to load and code compliance concepts.
Lesson 5 • Gutter Profile Styles
Compares K-style, half-round, and box gutter profiles by capacity and application. Students match profile to roof type and aesthetic requirements.
Chapter 3HideHide detailsSee detailsGutter Sizing and Layout Planning
Gutter Sizing and Layout Planning
Lesson 1 • Calculating Roof Drainage Area
Teaches horizontal projected area calculation for sloped roofs. Accurate area measurement is the foundation for all subsequent sizing decisions.
Lesson 2 • Layout Drawing and Documentation
Guides students in producing dimensioned gutter layout drawings with component callouts. Documentation skills support accurate material takeoffs and client communication.
Lesson 3 • Gutter Sizing Calculations
Applies flow rate formulas to determine minimum gutter cross-section for each roof plane. Students practice sizing K-style and half-round gutters using standard tables.
Lesson 4 • Rainfall Intensity and Design Storms
Explains how to read rainfall intensity maps and select design storm values. Students apply local intensity data to size drainage components conservatively.
Lesson 5 • Downspout Sizing and Placement
Determines downspout quantity, size, and spacing to match gutter capacity. Students learn maximum gutter run lengths and outlet spacing rules.
Chapter 4HideHide detailsSee detailsGutter Installation Techniques
Gutter Installation Techniques
Lesson 1 • End Cap and Outlet Installation
Demonstrates fitting, sealing, and securing end caps and outlet tubes. Watertight end caps and outlets are critical leak prevention points.
Lesson 2 • Establishing Correct Gutter Slope
Teaches chalk-line layout and slope calculation to ensure consistent water flow toward outlets. Proper slope prevents standing water and premature corrosion.
Lesson 3 • Cutting, Mitering, and Joining Sections
Covers tin snips, miter saw, and notching techniques for accurate gutter cuts and corner joints. Precise cuts reduce leak risk at every joint and corner.
Lesson 4 • Hanger Types and Fastening Methods
Compares spike-and-ferrule, hidden hanger, and strap hanger systems by load capacity and longevity. Students select and install hangers at correct spacing for each material.
Lesson 5 • Downspout Assembly and Attachment
Guides assembly of elbows, straight sections, and straps to route downspouts to discharge points. Secure attachment prevents wind damage and wall staining.
Chapter 5HideHide detailsSee detailsFlashing Materials and Types
Flashing Materials and Types
Lesson 1 • Purpose and Principles of Flashing
Defines flashing as a water-diverting barrier at roof transitions and penetrations. Students understand why flashing failure is a leading cause of roof leaks.
Lesson 2 • Self-Adhering and Flexible Flashings
Covers rubberized asphalt, butyl, and EPDM self-adhering flashing tapes and membranes. Students apply flexible flashings where rigid metal cannot conform to complex geometry.
Lesson 3 • Penetration Flashing Components
Covers pipe boots, vent collars, skylight curb flashings, and chimney flashing assemblies. Students identify each component and its role in a watertight penetration seal.
Lesson 4 • Metal Flashing Materials
Compares galvanized steel, aluminum, copper, and lead flashing by corrosion resistance, workability, and compatibility. Material choice affects service life and maintenance frequency.
Lesson 5 • Flashing Profile Types by Location
Identifies step, counter, base, valley, drip edge, and apron flashings by their roof location and function. Students select the correct profile for each transition type.
Chapter 6HideHide detailsSee detailsFlashing Installation Techniques
Flashing Installation Techniques
Lesson 1 • Metal Flashing Fabrication Skills
Teaches layout, scribing, cutting, and bending sheet metal using hand brakes and snips. Accurate fabrication is the prerequisite for every flashing installation task.
