The next time you walk outside, take a moment to gaze up at your roof. What do you see? Do you see even shingles that are all laying flat? Or do you see shingles that are starting to curl and that are covered in moss? You can tell a lot about the condition of your roof just by looking at it. If you are at all concerned about the state of your roof, then your first call should be to a roofing contractor. They can evaluate the situation and recommend repairs or replacement as needed.

Lots of things can go wrong with roofs, and that means a roofing company always has to assess the situation before committing to a solution. It is good for customers to know how a roofing company will approach this part of the job. You can expect roofing contractors to conduct assessments by looking for these four issues.
The scariest part of roofing work is where the roof gives out completely in some spots. A roofing company will have employees check both the outside and inside of the roof to see what kind of structural issues might be present.
For example, they'll check for signs that water has gotten through the shingles and damaged the underlying plywood. In the worst cases, the damage could extend to the rafters, support beams, or joists. These are the basic components that give the roof its shape. If those are damaged, the roofing company will have to remove and replace them before they can even consider attaching new felt and shingles.
Layers of Roofing Materials
In most cases, the structure is in good shape. The roofing company will proceed to assess just what's on the outside of the roof. Specifically, they'll look at how many layers of shingles are on the roof. Nailing a new layer of shingles into the old ones is a common practice because it saves their customers money. However, every layer adds thousands of pounds to the roof, and this eventually adds up to the point that the old materials have to come off. Otherwise, there is a risk the roof will collapse under its weight.
When a roof gets to this point, the contractors will strip it down to the plywood. This involves prying up the old layers of shingles and any protective felt. It also usually involves paying for at least one roll-off dumpster to haul away the junk.
Some roofs are more complex than others. Eaves, valleys, dormers, chimneys, and gables can all make it harder to work around the roof. Roofing contractors have to cut shingles to account for odd angles, increasing waste.
The slope of the roof determines how much equipment roofing contractors will need. If a roof has an aggressive slope, the roofing company may need to bring in additional equipment so its employees can safely work. That extra equipment comes at a cost, and it also tends to slow things down because workers have to move it as they go up and down the roof.
