There is no single roofing material that is best for every property. A decision should account for the existing structure, design, local climate, product specification, upkeep and the cost of changing roof details.
Consider the roof structure and layout
Tiles and sheet-metal systems have different weights, supports and installation details. Before switching materials, have the structure and roof design assessed and confirm what approvals or engineering advice may be needed.
Compare maintenance and repairs
Tile roofs may need attention to cracked tiles and ridge details; metal roofs may need checks of fasteners, coatings, flashings and material compatibility. Actual upkeep depends on installation, exposure and condition.
Compare written scopes, not slogans
Ask each contractor to specify the product, insulation, ventilation, flashings, drainage, removal and warranty terms. A product's general properties do not guarantee comfort or performance in a particular home.
Describe the roof concern to an independent professional.
Request a connection and discuss the property, quote and any next steps directly with the contractor.
