A West Fort Collins Roof at Three Stages
Drennen’s West Fort Collins project media follows the existing roof through installation work and a later shingle walkthrough. The original roof-detail photograph below is part of this same project media. The short clips add views of the earlier shingles, underlayment and exposed ridge area, and the later roof surface.
Existing roof
The camera follows the earlier shingle surface past roof vents and pipe penetrations.

This close view shows underlayment beside exposed decking and an opening along the ridge area.

If you’re weighing a repair against replacement, start with a roof inspection and a written scope for your property. See our roof inspection and certification services, learn more about attic ventilation, or review our Fort Collins roof replacement cost guide before requesting an estimate.
