Where two slopes meet · Metro Detroit
Valley repair.
Where water concentrates.
Valleys carry more water than any other part of a shingle roof. When metal pinholes or woven shingles fail, stains show up after every heavy rain. Partial valley rebuild $850–$1,250; full run $42 per linear foot — published in the price book.

Why valleys fail early
Debris, shade, and freeze-thaw hit valleys harder than the open field. Caulk and roof cement over a pinhole fail again within a season. We rebuild the detail so water sheds the way the roof was designed.
If the surrounding field shingles are truly done end-to-end, we’ll say so with photos. We still won’t sell a replacement — repair-only is the point of this company.
