“How much does a roofer weigh?” is a question I have been asking myself, and I don’t get the answer I want. I also find it kind of funny that people will actually tell me that I can’t see an estimate on a roof, because they want me to believe that I can, and guess what…I can’t! It’s really important for roofers to know not only the poundage they’re carrying, but also the quantity of tar or roofing shingles they need to complete a roof job. I’m sure you’ve been there: you’re standing on a ladder, surrounded by a huge mess of roofing materials, and you can’t see a thing. So, how do roofers say 300 pounds concentrated?
This question may seem trivial, but it is important. As a roofing contractor I am often asked how much heavy equipment they should be carrying on the roof. Here is my answer: As heavy as you can legally carry. You also need to understand how many tons of nails, shingles, I beams, metal flashings, metal clips or nails you are required to have on the roof. Calculating the weight of all these items takes some math, so if you are planning on being a roofer for the next 30 years or more, you better understand how the industry works.
If you were just buying a house, you would most likely not have a lot of heavy duty equipment on hand. Even if you did, how much would you use it? A home owner would never consider buying a home that didn’t have girders, and while roofers are required to be very precise in their calculations, they don’t go overboard. As a matter of fact, on average a roofer should carry about two tons of nails, shingles, or metal flashings. In addition, many roofers have high-powered back-up tools like nail guns.
So, how much do you need? That depends on several factors including the roof, the terrain and the climate of your area. Nails can be heavy and difficult to transport, especially in severe weather. In the winter when the temperature may dip below freezing, having long nails makes sense.
Another factor in figuring the load is the type of roofing material used. Most roofers say that asphalt shingles weigh about three tons. However, not all asphalt shingles are the same. They all have different combinations of fiberglass, asphalt and other additives. Some roofers prefer to use asphalt, because they are stronger than the fiberglass roofing products. Fiberglass does not hold up as well as asphalt shingles in high winds or extreme weather conditions.
The weight and size of a roof also depend on the design of the roof. Do you have a low slope roof or one that is arched? Are there valleys or other features in your roof design? These are all things that will affect how much weight a roofing contractor can safely lift. It is important to know exactly what your roofing system weighs, because if you have problems while doing your work, the only people who will truly benefit are those from the roof repair company.
One big question often asked is how much roofing material a roofer uses. Most roofers say that one pound of material is equal to eight pounds under average weight. Of course, roofing weights vary from house to house. For example, a two-story home will obviously carry a lot more weight than a single story house. If you have questions regarding the roofing material used on your home, ask your roofer for a recommended weight for your house.
There is no one rule for determining how much roofers should use in order to repair your roof. It will depend on the type of roof you have and whether or not it has been galvanized. It also depends on the number of nails being used and how long they have to be used before requiring a break. Again, always ask your roofers for recommendations, and if possible see their proof of insurance documents (often this is called a bonding certificate).
