First of all, you need to ensure the load is safe to be supported by roof. Is your roof enough strong with solid materials to carry the weight of ladder and you? One thing you can do here is checking the framework that is right beneath your roof. Make sure it is built solid to support any extra load that might come across. Also, keep in mind that a parallelly placed ladder will be able to distribute its own weight evenly on the roof framework.

Check the Duty Rating

The next thing you need to do is checking duty rating sticker available on your ladder. This is to know whether the load weight is safe to go for. Usually, you’ll need to go with at least the type II ladder. It should also include spring-loaded rung locks and real feet. Never risk it all by trusting on a flimsy footed ladder that includes cheap hook rung holders. These are surely very light but also extremely prone to cause a disaster.



Slippery Roofs

There are certain roofs that are made from slate tile. And so, these are pretty slippery. As a result, you will not be able to get a good stable footing on it with a ladder. If you need to put your ladder on such a sloped roof, then be very careful on the footing.

Also, you should ask for help from a friend or family member who can hold the ladder while you’re on top of it. This will keep things much safer than trying it alone.

Cleaning the Surrounding

Inspect Your Ladder

That’s obviously inviting a big accident to yourself.

Be Careful of Electrical Wire

Sometimes overhead power lines end up making huge accidents if not taken care of properly earlier to such tasks. So, make sure you check gradually your surrounding and get rid of any electrical wire that can cause trouble.

Side Slop & Back Slant Consideration

You should not place the ladder on a surface that side slope seems to be bigger than 16 degrees. Also, make sure the back slant is no more than 6-degree. In case the manufacturer states this to be safe, then you can proceed.
