Before and After
What is shown here represents completed projects where Derek Cook's Roofing Specialists transformed the exterior of homes across New Hampshire. These are not quick cosmetic upgrades—they are full replacement or significant repair work, photographed at completion to show the scale and finish quality of their installation.
The selection at a glance
Each project in our showcase was selected to illustrate a different challenge or material choice. This table breaks down the scope across the work we have reviewed most closely.
| Project Type | Primary Material | Scope & Timeline |
|---|---|---|
| Full Roof Replacement | Architectural Asphalt Shingles | 3000+ sq ft, 5–7 days |
| Roof + Soffit Restoration | Metal Standing Seam / Cedar | 2500 sq ft, 2–3 weeks (includes trim work) |
| Storm Damage Repair | Mixed (shingles + structural deck) | Partial replacement, 2–4 days |
| New Construction Roofing | Composite Shingles | 4000+ sq ft, 7–10 days (custom pitch) |
How each was chosen
Our project selection follows a sequence designed to show breadth across the most common decisions a homeowner faces.
- Scope clarity. We prioritize projects where the before-and-after boundary is unmistakable—not a detail change, but a full system replacement or significant structural work that reads visually from street level.
- Material diversity. A roof is not just asphalt shingles. The gallery includes metal standing seam, architectural shingles, and composite options, because the material choice matters as much as the installation quality.
- Timeline representation. We include both quick turnarounds (emergency repairs) and longer jobs (new construction or full restoration with custom details), so visitors understand how long their own project might take.
- Location and season. All projects shown are from the New Hampshire region where Derek Cook's crew works, and they span multiple seasons—because roofing happens year-round and weather conditions change the job's complexity.
Why these and not others
Not every completed job makes it into this gallery. We exclude quick patch repairs, purely cosmetic work, and projects where the lighting or angle does not clearly show the quality of the installation. Roofing photographs taken at an angle often mislead about the actual work—overhanging trees hide details, poor lighting flattens texture, and a good-looking photo can come from mediocre work while a harder light reveals the joins and transitions that actually matter. We keep this collection to projects where the photograph honestly represents the work's finish and scope.
These are the ones where a homeowner can look at the before image and the final installation side-by-side and understand: this is what good roofing looks like when it is complete. This is what the repair takes. This is the timeline. This is the material choice in context. If you are deciding whether to call and get a quote from Derek Cook's team, these projects show the standard they work to.
