Castro Roofing can help you with your roofing repair. In some cases nails will “pop” through the shingles due to pneumatic nail guns not sinking the nails to proper depth. Some cases roofing companies are not educated with flashing properly, so they will re use the old flashing. That will certainly fail in time. (We always change all flashing with a new roof installation). In this case if your chimney, pipe boots, valleys or wall junctions are leaking. Castro Roofing’s experienced professional roofers can most likely repair your roof without replacing it.
