I am in NW Ohio. Had a roof installed last fall. Been fighting with the company since then about shoddy workmanship. In an area of about 2 squares I have found over 20 locations where nails are coming thru shingles. We have several rows close to 50’ long where the offset is less than 4". In addition to the nails coming thru I have found about 10 places where partial nail heads are exposed because the shingle exposure is not correct.
The installer want to just “repair” while I want a complete replacement because I question the ability to remove a few rows, the entire length without causing more damage to surrounding shingles.
Also With so many nails coming thru in one area I am concerned that in a few years other may work thru.
This was NOT the cheapest company. Actually the most expensive one.
What would you do to encourage them to replace the entire roof?
