07 Apr Does your roof have these?
This is not a common mistake, but this is not how a professional roofer installs shingles on the ridge of a house or garage.
These architectural shingles may tear off during heavy winds, and cause possible roof leaks.
Ridge cap shingles are not cheap, but are a must for the ridge of a house. These will need to be removed and repaired by a qualified and experienced roofing contractor.
