How Much Should Roof Tile Overhang?

Depending on the tiles’ size and the roof’s pitch, they should overlap by 75mm to 100mm. This means that the gauge of your roofing battens should be roughly 32-35cm, measured from the top of one batten to the top of the one underneath it.

It also depends on the tiles, meaning which type of tile you use, but the general rule is a typical roof tile will cover approximately 75mm to 100mm of overhang. In a nutshell, that’s all there is to it.

This gives the right amount of space for the roof tiles to fit into, meaning they won’t easily fall off during the rain or snow.

However, you should be aware that this isn’t always feasible for some installations and can cause problems with tiles not being able to sit properly and compromising your overall design.

What Is The Code On The Roof Overhang?

The code on the roof overhang refers to the maximum horizontal distance the overhang can extend. This distance is typically measured in inches or millimeters; in this case, the maximum distance is 24 inches (610 mm).

This code aims to ensure that the overhang does not extend too far and create a safety hazard. Also, if the overhang extends too far, it can cause damage or leaks to water or plumbing.

How Much Overhang Should An EPDM Roof Have?

When you purchase the EPDM sheet, you will receive one huge sheet. As a result, you’ll need to calculate the size of your roof. Allow for a 150mm material overhang on each edge (so add 300mm to the overall dimension). Allow for the roof’s slope and edge overhangs as well.

The slope dimension is bigger than the plan dimension of the structure, so to ensure a straight, leak-proof roof, leave a 150mm edge overhanging the structure on each side. This should be 600mm to 700mm of overhang for the EPDM roof.

The overhanging part is covered in detail with PVC. This roofing material doesn’t require support from underneath, but you can still use a batten if you wish to do so.

For the overlapping bit, it is preferably 300 mm on one side and 150mm on the other side.

The larger your overhang extends past your building; the more rigid your structure will need to support it.

Does Lot Coverage Include Roof Overhang?

Lot coverage is the proportion of a lot’s area covered by the perpendicular projections onto a horizontal plane of all structures or mobile homes on the lot, excluding balconies, canopies, and overhanging eaves that are 2 metres (6.56 feet) or higher over finished grade.

It is expressed as a percentage and varies with municipalities. For example, in Seattle, lot coverage is 60 percent (meaning you can only build to a maximum of 40 percent of your lot).

The maximum lot coverage in Vancouver is 100 percent, although most zoning districts allow only 75 percent.

A building’s roof overhang typically measures lot coverage. For example, if your roof extends 16 feet (4.88 m) beyond the walls of your house and the lot coverage in your area is 80 percent, you can only build a structure to a maximum of 96 square feet (9 sq m).

If you live in a heavily congested area with small lots, you’ll want to check the codes on lot coverage and underutilization, as well as minimum yard requirements.

This will help ensure that you maximize the space available on your property by meeting the codes without violating them or incurring fines for non-compliance.
