There are so many people around the world who would like to know what the maximum weight that roofers should use on a roof. Some contractors and roofing companies say that there should be no maximum weight for roofers to use. In fact some contractors say that the weight should be only half of that. The question is why do roofers say that there should be no maximum or minimum weight?
What is the difference between saying that there should be no maximum and minimum weight for roofers to use on a roof and stating that there should be no maximum weight and no minimum weight for heavy materials? What is the difference between saying that there should be no concentrated load and saying that there should be a concentration of load? If the contractors are saying that there should be no concentrated load, why are they saying it? This article will try to answer these questions.
In order to understand why the roofers say that there should be no maximum or minimum weight, one must first understand what a roofing contractor is talking about when he or she states that there should be no concentration of load on a roof. A roofer’s term for “loads” is actually a measurement that can include both the weight of the roof materials roofers say 300 pounds concentrated as well as the pressure that is applied to the roof. Basically the term is used to describe the amount of force that is being applied to the roof and the materials and the roofing structure. These loads can be measured in pounds per square foot or in the pounds per linear foot.
In other words, if the roofers say that there should be no maximum load because there will be no stress on the roof, but the roof is still stressed at the necessary limits then that would be a load which would exceed the maximum stresses set by the roof. The roofers say that this type of roofing system should be used on heavier materials and with heavier loads the roof will last longer. Now, the roofers can make their argument from experience because they have built thousands of these systems themselves and they can testify to that. That does not mean that they are correct about the practicality of their statement, but it does mean that some of the limitations that they have mentioned might actually apply to some applications and certain roof types.
The maximum load that is stated by many roofers say that it should be no more than the sum of the first five feet of the roof span of the building or structure to be erected. They also recommend that the load should be no less than 300 pounds per square foot and that it should be spread over the length and width of the roof to be erected. So, basically the roofers say that you can have as much load on your roof as you like, but it has to conform to the building codes and it has to be of the right type.
In other words, the roofers are saying that you are going to have to buy their special roofing materials which cost them a lot of money, but that if you follow the roofing rules then you shouldn’t really have to pay for them at all. This means that you could have a perfectly sound roof without buying all those expensive roofing materials. The roofing code in most states is designed so that you are supposed to use the minimum amount of roofing materials that are required, but this doesn’t mean that you have to break the bank buying these roofing materials. It just means that you have to buy only what is specified in the roofing code.
There are many reasons why roofers say that you need to follow the roofing codes, but there are also many practical reasons why you shouldn’t have to adhere to all the roofing codes, unless you want to. One of the reasons why you shouldn’t have to break the law is because you are not the one who is actually causing the damage to the roof. If you are just adding water on top of the water which already exists on your roof, then you are simply adding concentrated load to the roof without doing anything which would give rise to building codes being broken. You should be concentrating on making sure that you don’t cause any further damage by not adding concentrated load to the roof. If you want to make sure that you don’t cause any more damage, then it is important to follow the roofing system regulations which have been set down by the state.
What would happen if you ignored the laws and added more water to the roof? Would it still be standing after a few years? Probably yes, but you wouldn’t know that because it would have been causing the roof to expand. By following the roofing system regulations you will be safe in the knowledge that the roof will not expand due to any type of concentrated load.
