Some roof questions. my roof shingles look great but some neighbor's shingles are all streaking. Looking at previous posts, it must be mold. Roof shingles are either fiberglas based or organic felts? Is it just the organic based shingles that the mold attacks? mold eats the organics? are the architectural type shingles fibergas based? Final question...do you install a new gutter after the roof is on? if so, the drip edge flashing is under the side of the gutter. do you get water between the gutter and fascia? THANKS bill

Just address the moss issues directly. Neither type of shingle is totally moss proof. Local conditions seem to make a difference in what is the best solution so maybe you should ask around. I would consider zinc strips if I were you as they seem to be the most effective overall.
