Steep slope roofs represent the majority of single family homes, townhouses and duplexes. The term describes any roof other than flat roofs with a slope of 2 inches of vertical rise for every 12 inches of horizontal run. A roof with this slope is described by the ratio 2:12. A more common roof slope, 4:12, rises four inches for every 12 inches of horizontal run.

The term misleads somewhat. Steep slope roof merely differentiates the type of roof used on most residences from the flat roofs found on most commercial structures. A roof with a 2:12 pitch comes close to being flat. Most people could walk on a roof with a 4:12 pitch without much difficulty. Roofers consider an 8:12 pitch the steepest pitch walkable, meaning that they can work on the roof without the use of hands or other aids.

Newport News roofers that concentrate on steep sloped roofs use asphalt shingles, wood shakes and shingles, clay and concrete tile, metal shingles and panels in new construction and remodeling projects.

The importance of a roof's slope relates to the time required to install any selected roofing material. The higher the slope, the longer it takes.

Very steep roofs, those with ratios of 7:12 or 8:12 require far more time for installation than do those with the more commonly encountered 4:12 and 5:12 slopes. Explaining the difference to a homeowner who balks at an estimate that substantially exceeds the price paid by someone of the homeowner's acquaintance with a similar house will likely provide clarity. Steeper roofs offer a superior ability to shed water from rain and snow. This enables them to last longer, which over time, makes up for the initial difference in the price and pace of installation.

Homes with mansard style roofs often have pitches beginning at 21:12 and going to as much as 60:12, only a bit short of vertical. Safety harnesses, special ladders and scaffolding make it possible for roofers to work on near vertical roof decks. Installation slows considerably due to the caution required for safe work on highly pitched roofs. Even granular coated roofing materials that typically provide good traction require extra care. The potential for slips and falls increases even more when slippery slate and metal roofing materials come into play.

Many modern homes feature multiple roof lines. Small sections of roof over dormers and similar architectural features present pitches steeper than the rest of the roof. Professional, experienced roofers can often determine different pitches without actually measuring them but will verify with measurements for generating an accurate estimate.
