FAQ
- What is a bundle?
- A pack of shingles. Coverage per bundle is printed on the wrapping. Three square metres is the default here, not a standard you should assume.
- Does this include starter strips and ridge?
- No. Order those from the manufacturer’s instructions, on top of the field bundles.
- Should I add waste?
- Increase the roof area, or reduce the cover per bundle slightly, if hips and valleys will waste shingles.
