Questions
Are there always three bundles in a square?
No. Three is common, but bundle coverage varies by product and manufacturer. Verify the selected product.
Does this include starter and ridge cap?
No. Those may be separate products and require edge measurements and manufacturer-specific coverage.
Can I order from this number alone?
No. Verify measurements, product coverage, waste, accessories, local code, and installer requirements.
