Rafter

Rafters are the sloped structural members — typically 2x8s, 2x10s, or larger — that run from the ridge down to the eaves, forming the skeleton of a stick-framed roof. The decking nails to the rafters; everything above depends on them.

In stick-framed (rafter) roofs, each rafter is cut and placed individually — an older, more labor-intensive method that leaves the attic open and usable. Most modern homes instead use prefabricated trusses, which are cheaper and stronger per dollar but fill the attic with webbing.

Rafter problems — sagging, cracking, or rot from long-term leaks — are structural issues, not roofing issues, but roofers discover them during tear-offs when the deck comes up. Sistering or replacing damaged rafters is carpentry work that must happen before the new roof goes on.

Why It Matters

A roof is only as sound as its framing. If a tear-off reveals damaged rafters, address them properly — roofing over structural damage just hides it at greater expense.
