What goes on the roof next
Useful life is HUD’s planning figure, not a warranty. More in the guides to shingles, metal, slate and flat roofs.
| Material | HUD useful life | Fits a house like | Watch for |
|---|---|---|---|
| Asphalt shingles | 20 years | Most pitched roofs; 74% of homes here are detached | Class G or H at 127 mph design wind (IRC Table R905.2.4.1) |
| Metal (standing seam, panels) | 50 years | Simple roofs with long, unbroken slopes | A complete standing-seam system may go over the old roof (R908.3.1) |
| Slate | 75 years | Older and historic houses | Never a base for a new layer (R908.3.1.1); heavy |
| Flat roof: EPDM or TPO | 15 years | Additions and porch roofs | Coating is not a replacement |
