**Q: Do I need a permit for a Markham roof replacement?**

Yes, the City of Markham (York Region) requires a building permit for most roof replacements involving material change or structural work. We file every York Region permit ourselves. Typical issuance is 5–10 business days for residential roofing.

**Q: Do you work on Unionville heritage homes?**

Yes. Unionville's character properties often require heritage-appropriate materials and finishes. We work with Markham's heritage requirements and have completed installations on multiple Unionville character homes — references available.

**Q: How fast can you start a Markham project?**

Free assessments scheduled within 48 hours. From signed agreement to install, typical Markham timeline is 3–5 weeks depending on permit timing and material lead time. Standing-seam metal has the longest lead time; asphalt shingles ship within a week.

**Q: What warranty do you provide on a Markham roof?**

Standard manufacturer warranty (25–50 years for metal, 15–30 years for asphalt) plus Buildoreno's own 5–10 year workmanship warranty in writing. We don't subcontract — the same crew that installed your roof is who we send back if anything ever needs attention.
