Here is some helpful information you should know:
- What type of shingles does your roof have?
Wood Shake shingles:
Regular Asphalt shingles:
- Is your roof walkable?
The following roof pitches are what we consider walkable:
- 2/12 pitch
- 4/12 pitch
- 5/12 pitch
- 6/12 pitch
- 7/12 pitch
- But how do you determine the pitch of your roof, to know if it’s walkable or not?
- Pitch (or slope) – measures the amount of rise your roof has compared to the length. In other words, for every twelve inches of length your roof will rise a set number of inches. The diagram below illustrates a roof that has a 7-inch rise for every 12 inches of length, thus it has a 7-inch slope or pitch (also conveyed as 7/12).
- How to determine the pitch of your roof:
There are two ways to determine the pitch of your roof; either from the roof or the attic.
- If on the roof, take a level, and then you will make a mark at 12” from the end.
When you are at the top of the ladder, you will hold the level straight, so the bubble is centered, and then measure the vertical distance down from the bottom right end of your 12” mark on the level down to the roof.
- If in the attic, place the end of the level against the bottom of a roof-supporting rafter. Make sure the level is horizontal, and measure up from the 12” mark to the underside of the rafter.
- Do you have gutter guards? If so, do they snap on or do they screw on?
