Conventional slope roofs are most common with residential roofs. This means the slope has a pitch between 4/12 and 9/12 on most homes. Roofs with a pitch exceeding 9/12 are called steep slope roofs.
What is the best roof pitch?
For metal panel roof systems, NRCA recommends slopes of 1/2:12 or more for structural panel systems and 3:12 or more for architectural panel systems. For asphalt shingle, clay and concrete tile, metal shingle, slate and wood shake and shingle roof systems, NRCA recommends slopes of 4:12 or more.
What is a traditional roof pitch?
The modern roof pitch has been made at a ‘standard’ 45 degrees. When comparing it to the steeper pitch of the old whitewashed range, it somehow seems wrong.
Is a 4/12 roof pitch good?
4/12 is quite typical. Anything under 3/12 is a low pitch roof. Anything above 6/12 is a steep roof pitch since it becomes harder to walk on the roof.
What is the cheapest roof pitch?
A low pitch or walkable roof is one that can be safely walked on without more than basic safely measures. This term is typically applied to roofs with a pitch of three fourths or 8/12. The increased risk of falling means they need more safety equipment to work on such a roof.
What kind of roof do I need for a 2 12 pitch?
Metal roofing made of steel and copper are ideal for shallow-pitched roofs. In fact, a properly installed metal roof can be used on roofs as shallow as 1/2 inch/12 inches, which is almost flat.
At what pitch does a roof become a wall?
The National Calculation Methodology (NCM) modelling guide (for buildings other than dwellings in England) 2013 edition, published by the Department for Communities and Local Government (DCLG) considers that a pitched roof is a ‘Roof with pitch greater than 20 deg and less than or equal to 70 deg – if the pitch is …
What are the types of roof pitches?
The most common r00f pitch on residential homes falls between 4/12 and 9/12. A “walkable-roof” is generally defined as having a roof pitch of 7/12 or below. There are many different types of pitched roofs including gable roofs, hip roofs, gambrel roofs, dome roofs, and mansard roofs.

Can you Shingle A 2 12 pitch roof?
While roofs with a 4/12 pitch and steeper are ideal, the minimum roof pitch for shingles is 2/12. A roof with a 2/12 pitch can safely use shingles by incorporating additional layers of underlayment around the eaves.
Is a 6 12 roof steep?
The 6/12 roof pitch is by far the most common residential roof pitch. It is steep enough to shed water quickly while also being what we refer to as “walkable”.
Are higher pitch roofs more expensive?
A roof with a high pitch is commonly 6/12 – or 6 inches in height for every 12 inches across. When making roof decisions, many people think these roofs require more materials and cost more money. Thus, they are often tempted to go with a low slope. However, 6/12 and higher rooftops are valuable—and for good reason.
What is the lowest shingle pitch?
What is the Minimum Slope for an Asphalt Shingle Roof. The short, simple answer is 2:12 has traditionally been considered the absolute minimum acceptable roof slope suitable for asphalt shingles. Asphalt shingles continue to be the most widely installed roof covering option in North America.
