So can walking on your tile roof harm it? Yes, you can. HOWEVER, the probability and level of severity depend on the time of year. Herpes zoster is resistant and is made to withstand occasional walking. However, if it's hot outside, say 80 degrees, and there is direct sunlight on the roof, the asphalt base of the tile will softenProfessional roofers know better than anyone when conditions are safe and you shouldn't walk on the roof if they tell you it isn't.
It's usually not a good idea to stand on the roof. On the one hand, you can damage the roof tiles or even slip and fall due to moisture or algae buildup (if it's an external problem). While this depends largely on the definition of “good”, walking on tiles of various types can, in fact, damage them. In addition to the risk of damaging roof tiles, broken roof tiles can also create a fall hazard and cause injuries.
Fiberglass ladders are durable, but aluminum ladders can also work if you need something lighter. Secure the ladder to an anchor point with a cord or rope to prevent it from slipping from side to side. Find an observer to help you keep the ladder stable as you climb. This will allow you to have three points of contact, which will help to further secure the ladder.
While there are several factors that can make walking on the roof more or less safe, walking on the roof is dangerous. The safest option is to keep your feet on the ground and hire a professional to step up and take the risk. The next question to ask yourself is whether or not it's good for your roof to walk on it. If you have stepped on your roof yourself, insurance companies may not accept any other claims you file in this regard. While you can fix the leak or hang up the Christmas lights if you're a homeowner walking around your room, climbing onto the roof on your own poses serious safety and insurance risks.
If you are not used to walking on roofs, you should keep this in mind and act with great caution. Walking on the roof can also cause other problems, such as water loss due to a poorly placed tile that wasn't replaced as well as it should be. Remember that if you are not safe walking on your roof or are uncomfortable doing so, it's best to hire a professional roofing contractor who has the experience and equipment to navigate the roof safely without causing any damage. Once you know the slope of your roof, it will be much easier to determine if it's safe to walk on it.
While there may not be any visible damage when walking on the roof, a leak may form that could cause extensive damage to the home during the next rain storm. Roofers are trained to walk on sloped surfaces, so contact a roofing professional first if you plan to do repairs in your roof. Even something as small as a loose tile or a missing nail can cause slips and falls, so it's always best to have a professional roofer check the roof before deciding if it's safe to walk on the roof or not.
