Roofing
Complete replacement and new installation only
A complete roof replacement, start to finish
Full replacement and new roof installation for houses across the area. The existing covering comes off, the deck is reviewed, and a new roof system goes on as one project with one scope.

The project
Four stages, old roof to new
- 01
Project review and measurement
Roof area, pitch, the number of existing layers and site access are measured, so the quote covers the whole project rather than an estimate of it.
- 02
Removal down to the deck
Existing covering and underlayment come off. The deck is then reviewed as part of the replacement, because what it can carry decides the system above it.
- 03
Deck, underlayment and edge metal
Sheathing that cannot carry the new roof is replaced, then underlayment, drip edge and valley metal are installed before any field material goes down.
- 04
New roof system installed
Field shingles or panels, ridge cap, intake and ridge ventilation, and all edge and penetration details are installed together as one finished system.
Roof systems
Three systems, three different projects
Asphalt shingle
The common choice for pitched residential roofs: wide colour range, familiar installation, and straightforward replacement of a worn covering.
Standing-seam metal
Long panels with concealed fasteners. Suits both simple and complex roof shapes, and is usually specified as a full replacement system.
Clay or concrete tile
Heavy tile systems for warmer climates. The framing has to be sized for the tile weight, which is established during the project review.
What shapes a replacement quote
- Measured roof area, pitch and the complexity of hips, valleys and dormers.
- How many existing layers have to be removed and disposed of.
- Deck condition once the old covering is off, and how much sheathing needs replacing.
- Ventilation, edge metal and penetration details included in the system.
- Access, staging and the number of working days on site.
Common questions
Roof replacement questions
How long does a complete replacement take?
Most houses run two to four working days once materials are on site. Size, pitch, the number of layers being removed and weather all move that number.
Does the whole covering come off?
For a complete replacement, yes. Existing covering and underlayment are removed so the deck can be reviewed before the new system is installed.
Can a new roof go over the old one?
That is a different scope with different limits. This service is complete replacement and new installation, so the old layers are removed rather than covered.
Is ventilation part of the project?
Intake and ridge ventilation are planned with the replacement, not added afterwards, because they belong to the roof system being installed.
Planning a complete roof replacement?
Have the roof area and the number of existing layers ready. Both shape the project.
