What metal Roofing covers
Metal roofing performs well on low pitches and awkward shapes, and it fails at its details rather than its panels. Fixings, seams, movement provision and the junctions with walls and penetrations are where a metal roof leaks, and where the work concentrates.

Metal roof installation and repair, where the panel is straightforward and the detailing is where the work is.
Waystar carries out this work on residential and commercial property in Brooklyn and across New York City. Every project starts with a look at the building, and the scope, the materials and the figures are written down before anything begins.
When might you need it?
These are the signs owners usually notice first.
- Water tracking in at a seam or a lap rather than mid panel
- Fixings backed out or their washers perished
- Panels oil canning or moving noisily with temperature
- Corrosion starting at cut edges or around penetrations
- A flashing at a wall abutment that has lifted
What the work involves
- Survey of seams, fixings, penetrations and abutments
- Substrate and support checked before specifying panels
- Panels set out to suit the roof geometry
- Seams closed and fixings set to the correct pattern
- Movement provision built in rather than fixed rigid
- Flashings and penetrations detailed and sealed
How the process works
Survey the details, not the panels
On a metal roof the seams and abutments decide performance.
Set out the panels
Panel layout is worked out to the roof geometry before anything is cut.
Install with movement allowed
Fixings and seams are set so the roof can move with temperature.
Detail every junction
Penetrations, abutments and edges are flashed and checked.
What you get
- A covering that suits low pitches where other systems struggle
- Details that allow for thermal movement instead of fighting it
- A long life covering when the junctions are done properly
What affects the scope
- Roof geometry and how many cuts and junctions it creates
- The condition and flatness of the supporting structure
- Panel profile and finish specified for the exposure
- Access for handling long panels safely
This is a preliminary planning range, not a quote. A property visit is required before any price is confirmed.
Frequently asked questions
Is a metal roof noisy in rain?
Far less than people expect once it is over a deck and insulation. Noise is mostly an issue on uninsulated open frame structures.
Can metal go over an existing roof?
Sometimes, on a suitable substrate. It depends on what is underneath, the loading and whether trapping the old covering causes a moisture problem.
Where do metal roofs usually leak?
At penetrations, abutments and fixings, almost never in the middle of a panel. That is where a survey looks first.
