Asphalt shingles: overview
Asphalt shingles are common on U.S. homes and available in many styles and product grades. Architectural/dimensional products are widely offered, while exact construction and warranty terms vary by manufacturer.
Asphalt: planning considerations
- Broad contractor/material availability in many markets
- Many colors and styles
- Roof slope/product requirements still apply
- Underlayment, flashing and ventilation remain critical
- Product line should be identified in the contract
Metal roofing: overview
“Metal roof” describes multiple systems. Standing-seam/concealed-fastener and exposed-fastener systems have different details. Panel material, coating, seams, clips/fasteners, penetrations, flashing, and substrate all matter.
Metal: planning considerations
- Long-term system choice for many homeowners
- Distinct appearance
- Installer experience with the specific system matters
- Expansion/contraction and penetration details require appropriate design
- Installed price can differ substantially from asphalt
Tile roofing: overview
Clay and concrete tile create a different roof assembly. Tile weight, structural suitability, underlayment, flashing, attachment, walking/access, and replacement of broken units are important considerations.
Tile: planning considerations
- Distinctive appearance
- Structural weight must be considered
- Underlayment is an important part of the assembly
- Individual tiles can be vulnerable to breakage from traffic or impact
- Contractor experience with tile systems matters
Weight and structural suitability
Do not assume a home designed for one roof covering can accept every alternative. If changing to a substantially heavier system, ask whether structural evaluation or approvals are appropriate.
Climate and location
Wind, hail, heat, snow, wildfire exposure, salt air, and local code can affect product and installation choices. Manufacturer documentation and local requirements should guide the specific project.
Cost comparison
Compare complete installed proposals. Material-only price does not account for tear-off, deck work, underlayment, flashing, labor, accessories, permits, disposal, or structural work.
Warranty comparison
Read actual manufacturer and workmanship warranty documents. Warranty duration alone does not tell you what is covered, excluded, prorated, transferable, or required for a claim.
Decision checklist
- Is the system appropriate for the roof slope and structure?
- Does it fit local climate/code requirements?
- Is the installer experienced with the specific system?
- What maintenance is expected?
- What is the complete installed scope and price?
- What do the written warranties actually cover?
