A professional will start by taking a look at permits in a local area. This includes seeing if the new items to place on a roof can actually be accepted in a community. Some communities have rules on what types of surfaces can be used in a local area.
The roof has to be measured in square feet to get a careful idea of just how much material is required. The professional must especially factor in individual flat surfaces to see how many materials may be utilized in smaller spaces.
Some additional reviews must be made based on the angles for the job. Angles can include many spaces where the roof slants or adjusts its appearance. The goal will be to cut apart individual roofing tiles so they can fit onto a space without overlapping anything.
A few materials for the job will also be brought in by the professional. These re-roofing materials may include such things as a dumpster to take care of the individual tiles that were removed and tarp surfaces to protect the roof's membrane when an area is not being worked on. This may be critical in the event of a rainstorm during the re-roofing process.
Finally, the professional will create a schedule for which parts of the roof are to be removed and replaced. Only one section of a roof can be replaced at a time. This is to not only make the process easy to handle but also to analyze a space to see if there are any damages from rot. All damages have to be accordingly to ensure there's no issue with getting a roofing job treated right.
