What is 7:12 in degrees?

A 7:12 roof pitch equals 30.3° — the roof rises 7 inches for every 12 inches of horizontal run. As a grade that is 58.3%, and the pitch (slope) factor used for area is ×1.158.

What roofing materials can I use on a 7:12 roof?

At 7:12, the materials that meet their minimum-slope requirement are: Membrane (TPO / EPDM / built-up); Standing seam metal (mechanically seamed); Asphalt shingles (low-slope method); Clay / concrete tile; Exposed-fastener / metal shingles; Wood shakes & shingles; Asphalt shingles (standard); Natural slate. That is a code-minimum list, not a recommendation. See the recommended materials above, and always confirm against the product's installation instructions and local code.

How much more material does a 7:12 roof need than a flat roof?

About 15.8% more surface area than the flat footprint, because the slope lengthens every plane. Multiply your footprint area by ×1.158 to get the true roof surface area.

7:12 Roof Pitch

7/12 crosses into steep territory — just past the walkable threshold (6/12). Strong performer in snow and rain regions.

Walkability

Difficult — experienced only

Steep enough that most people should not walk it unaided. Roofers use roof jacks, toe boards, and fall protection here.

🏠 Common Uses for 7:12 Pitch

•Traditional two-story colonials
•Steeper Victorian designs
•Regions with heavy rainfall or snow
•Craftsman and bungalow roofs with more drama

🌦️ Best Climate Fit

•Moderate to heavy snow regions (PNW, Midwest)
•Wet climates (Seattle, Eastern seaboard)
•Ice dam-prone areas benefit from faster runoff

✅ Advantages

✓Excellent water and snow shedding
✓Better curb appeal and architectural presence
✓Longer shingle lifespan (less heat accumulation)
✓More attic space for storage or conversion

⚠️ Drawbacks

×No longer safely walkable without equipment
×Maintenance requires professional roofers
×~10-15% higher construction cost than 6/12
×More materials needed (larger surface area)

About 7:12 Pitch

A 7:12 (also written as 7/12) roof pitch means the roof rises 7 inches for every 12 inches of horizontal distance. Expressed as an angle, this is approximately 30.3 degrees, with a slope of 58.3%.

Asphalt shingles (most popular), architectural shingles, or wood shakes. Standard residential pitch range.

Compared to a flat roof of the same footprint, a 7:12 pitch roof has about 15.8% more surface area due to the slope. Use our roof area calculator to convert your footprint to actual roof surface, or go straight to shingle and cost estimates with a pitch multiplier of ×1.158.

Cost Impact of 7:12 Pitch

Starts to add noticeable cost over the 6:12 baseline — about 4% more material. The increased attic volume can be a benefit (more insulation space, potential for attic rooms). Labor cost begins to increase slightly as the slope becomes less comfortable to walk.

Building Code Notes

At 7:12, some roofing contractors begin using toe boards or roof jacks for safety, though it's still walkable for experienced crews. Check whether your local jurisdiction typically requires fall protection at this pitch — OSHA standards generally require it above 4:12 for commercial work, but residential rules vary by state.

Calculation Example

For a 35×42ft Craftsman home (1,470 sqft footprint) at 7:12 pitch: roof area = 1,470 × 1.158 = 1,702 sqft, about 17 squares. Compared to a 5:12 on the same footprint (1,592 sqft), the 7:12 adds about 110 sqft — roughly one extra square.
