Shingle program depends upon whether the current roof was eliminated or left the location and about the type of roofing material left in position. When the old roof was taken away or when reroofing is old roll roof or BUR, the shingle-application processes are the specific same as those for the new buildings.
Wooden shingle roofs that are altered with feathering strips are also shingled inside the same fashion as new construction.

The situation that differs from the brand new structure is going to be the use of fresh strip shingles within existing strip shingles. The nesting procedure explained earlier, reduces any unevenness that may well result in the shingles bridging across the butts of those old shingles.
If fresh eaves flashing were inserted, snap chalk lines to direct the installation of their shingles before the classes buttocks against the present courses.
For the starter class, remove the tab and two inches or far more from the very top of the starter strip shingles to ensure the remaining part is equal in diameter to the vulnerability of the older shingles, which is normally five inches.
Make certain the present shingles overhand the eaves far enough to carry water to the gutter. When they don’t, cut on the starter strip into a width that can do so. Don’t overlap the present course over.
For the remaining classes, the five-inch vulnerability is automatic and complies with all the present shingles. As in brand new construction, use the shingles round the groove as you move up the roofing.
