How the job goes
Inspection
Laps, blisters, flashing and drains are checked, and wet areas found.
Written scope
You get a written scope with photos: repair, coat or replace, and why.
Work
The crew repairs or installs the roof, flashes the details, and checks drainage before leaving.
What affects the price
We don't publish prices because no two roofs are the same. These are what move the number on your written estimate.
- Number of layers
- Two-ply systems take more material and labor than one.
- Tear-off
- How many old roofs are on the building and what has to come off.
- What is underneath
- Wet insulation or damaged decking has to be replaced, not covered.
- Details
- Walls, curbs, drains and rooftop equipment each need flashing.
- Access
- Height, landscaping, tight driveways and neighboring buildings change how the crew and materials get up and down.
The only way to a real number is to see the roof.
How it goes on

Sheets are heated with a torch to bond them.
Self-adhered
Peel-and-stick sheets, used where open flame isn't a good idea.
Cold-applied
Sheets set in adhesive.
Cap sheet
The top layer, often with granules or a reflective surface.
