Roof line not straight.

Crooked gutters can make a roof look crooked even if the roofline itself is straight. Roof lines should be arrow straight. Every 5 inches make a new mark until you get to the rop of the roof. Sometimes an uneven roof is simply a sign of minor errors or aberrations in construction.

It might be something basic you can handle yourself but. This will be the bottom of your board. It is probably feasible to straighten up the roof line a bit when the metal roof is installed. Run your string line from the nails and measure up from the string.

At other times the gutters may need to stay where they are so gravity can do its work. This droopiness could be caused by moisture and ventilation problems. The rotten wood may be because the sag has caused water to gather repeatedly in that area. Screw a 2x4 about 12 long with a small nail sticking out on the 1 1 2 side.

Use the chalk line to snap a straight line vertically every 6 inches. Ask an assistant to hold the end of a chalk line on the first shingle at the longest edge of the roof. Sometimes you can adjust gutters and vents for a more uniform appearance. After your floor is straight it is time to concentrate on the next floor s ceiling.

It also may just be due to structural age or possibly a defect in the original structure. Repeat this on both sides of the roof.
