Repair or replace?

Metal roofs frequently outlive their fasteners and sealants. A re-fastening and re-sealing programme can add years to a sound panel roof - get a condition assessment before accepting a replacement quote.

How the work is carried out

1. Measurement and system selection
2. Panel fabrication or ordering
3. Substrate preparation
4. Panel installation and trim
5. Final inspection

What affects the cost

• System type - standing seam costs more than exposed-fastener panel
• Panel gauge and coating
• Roof complexity and number of trim conditions
• Substrate and existing roof removal
• Coastal-grade materials where salt exposure applies

Virginia-specific considerations

In coastal Hampton Roads and the Eastern Shore, salt exposure affects metal and fastener selection. In the Shenandoah Valley, metal is valued for snow shedding and long service life on agricultural buildings.

Questions to ask contractors

• Is this standing seam or exposed-fastener, and why is that right for my roof?
• What coating and metal are specified, and how do they perform near salt air?
• How does the system accommodate thermal expansion?
• Are you licensed in Virginia, and what is your license number?
• Can you provide a current certificate of general liability and workers' compensation insurance?
• Who pulls the permit, and which jurisdiction issues it?
• What is included in the written scope - underlayment, flashing, ventilation, decking allowance and disposal?
• What warranty covers workmanship, and what covers materials?
• Who will be on site each day, and is the crew employed by you or subcontracted?
