Ventilation in our climate: intake (soffit) + exhaust (ridge); reducing ice dams and attic moisture.

We hired JExteriors after a hailstorm and they were fantastic from the first inspection to the final walk-through. The crew replaced our shingles, added proper ridge venting, and fixed a couple of soft spots they found . They finished in a day, cleaned up every nail and registered the manufacturer warranty for us. They were very friendly - couldn’t ask for better communication and also the invoice was as discussed with no surprises.
