8 years ago I had a complete roof replacement done. At the time I was pleased with the work. The team was professional and Oswaldo was responsive. However, I was up in my attic a few months ago and notice some water staining along the North wall just below where the chimney meets the roof. I suspect there's a spot where the flashing was not sealed or angled in such a way to assure the water flowed away from the valley and off the roof. I tried contacting Montalvo Construction repeatedly and received no response. Regretfully, I am now forced to have this work done by another company, one who IS responsive. I will settle the matter of reimbursement for this work with Montalvo at a later date. read more
