01Measuring Roofs: Slope, Area & Quantities

Every estimate starts with an accurate takeoff. Learn to measure any roof — level or sloped — and convert plan dimensions into real roof area.

02Roof Sheathing & Decking

The deck is the foundation of the roof system. Verify the structure, know your panel rules, and price hidden rot before it eats your profit.

03Underlayment, Dry-In & Flashing

The roof's second line of defense — underlayment, drip edge, eaves membrane and the flashing details that decide whether a roof ever leaks.

04Asphalt Shingles

The material on most American roofs. Master products, flawless nailing, and the complete takeoff — field, starter, caps, and accessories.

05Mineral-Surfaced Roll Roofing

The budget workhorse for sheds, porches and outbuildings — quick to lay, honest when sold for what it is, and full of lap details that matter.

06Wood Shingles & Shakes

Cedar delivers a look nothing else matches — and demands real craftsmanship, breathing room, and honest labor pricing.

07Concrete & Clay Tile

Tile roofs last generations — if the structure can carry them, the underlayment is premium, and every detail sheds water.

08Slate Roofing

The century roof. Slate is stone — beautiful, brittle, heavy, and unforgiving of shortcuts or the wrong nail.

09Metal Roofing

From ag panels to architectural standing seam — the fastest-growing steep-slope category, where every detail is about thermal movement.

10Built-Up Roofing (BUR) & Mod-Bit

When the roof goes flat the rules change: continuous membranes, laps, drainage — and fire discipline on every torch job.

11Elastomeric & Single-Ply Roofing

TPO, PVC and EPDM own modern commercial roofing — membrane choice, attachment method and seam quality decide whether it lasts twenty years.

12Insulation, Vapor Retarders & Waterproofing

The roof system doesn't stop at the shingles — heat, moisture and water vapor all have to be managed, or the building rots from the inside.

13Roof Coatings

Fluid-applied restoration and spray foam — extending sound roofs for a fraction of replacement cost, and feeding the maintenance-contract business.

14Roof Repair, Maintenance & Re-Roofing

Finding leaks, judging hail and wind damage, and making the overlay-vs-tear-off call — the service side of the business, where trust is built.

15Estimating, Overhead & Bidding to Win

The capstone: turning takeoffs into profitable bids. Costs are facts; price is strategy — and overhead is not profit.
