Roof Inspection in Mill Valley, CA

What Does a Roof Inspection Include?

A professional roof inspection is a systematic examination of your entire roofing assembly, not just a quick glance at the surface. For a Mill Valley home, this means checking every component that protects your structure from the heavy winter rains and coastal fog that characterize our climate.

Our inspectors start with the interior, looking for signs of water intrusion in your attic or ceiling joists. We check for dark streaks, damp insulation, or rot in the wood decking—these are often the first clues that moisture has seeped past your outer layers. Then we move to the exterior, walking the roof surface to examine each course of shingles. We look for granule loss, curling, cracking, or blistering that signal end-of-life wear. We also inspect all flashing around chimneys, skylights, and valleys, since these are the most common points of failure.

Materials and Methods We Use

During a roof inspection, we assess the condition of your existing materials—whether you have asphalt shingles, metal panels, clay tiles, or a flat membrane roof. We check for proper installation of starter courses and field courses, and we verify that staggered courses are correctly aligned to prevent water from wicking along the seams. We also test the integrity of self-adhered underlayment in critical areas like valleys and eaves, where ice dams can form.

For homes with older roofs, we pay special attention to the condition of the decking beneath. We look for sag or settle that might indicate structural issues, and we check for overdriven or exposed fasteners that could compromise the water-shedding ability of the shingles.

How Much Does a Roof Inspection Cost in Mill Valley?

A standard roof inspection from Mill Valley Roofing costs between $150 and $400, depending on the size and complexity of your roof. For most single-family homes in areas like Alto or Strawberry, you can expect to pay around $250. This fee includes a detailed written report with photographs, a digital copy for your records, and a clear explanation of any issues we find.

If you're in the process of buying or selling a home, we also offer a more comprehensive pre-purchase inspection that includes a written certification of the roof's condition. This typically costs $350 to $500 and can save you thousands in unexpected repairs down the line.

Signs You Need a Roof Inspection

You should schedule a roof inspection at least once a year, ideally in the fall before the winter rains arrive. But there are specific warning signs that should prompt you to call sooner:

• Missing, cracked, or curling shingles visible from the ground
• Granules accumulating in your gutters or downspouts
• Water stains on your ceiling or walls, indicating an active leak
• Daylight visible through your attic or roof boards
• Moss or algae growth, which can trap moisture and accelerate decay
• Damaged or loose flashing around chimneys, vents, or skylights
• Sagging or dipping areas on your roofline

In Mill Valley, the combination of morning fog and winter storms creates a unique environment. The constant moisture can cause asphalt shingles to erode faster than in drier climates, and the temperature swings can make materials expand and contract, leading to cracks and splits. That's why a local inspection is so important—we know what to look for in your specific conditions.

Our Step-by-Step Inspection Process

1. Interior Examination: We start in your attic, checking for leaks, rot, or inadequate ventilation. We look for water stains, mold, or damp insulation that indicate a problem.
2. Exterior Walk: We walk the roof surface, inspecting every shingle, flashing, and vent boot. We use ring-shank nails to secure any loose areas we find, and we note any areas that need repair.
3. Flashing and Penetration Check: We closely examine all flashing around chimneys, skylights, and plumbing vents, resealing any gaps with a high-quality sealant.
4. Gutter and Downspout Inspection: We check your gutters for debris and ensure they're properly attached and draining away from your foundation.
5. Detailed Report: Within 24 hours, you'll receive a written report with photos, a condition rating, and specific recommendations. We include a priority list so you know what needs immediate attention and what can wait.
6. Follow-Up: If we find issues, we'll provide a clear estimate for repairs. If your roof is in good shape, we'll give you a timeline for future maintenance.

Insurance and Warranty Considerations

If you've recently experienced storm damage, a roof inspection is often the first step in filing an insurance claim. We document all damage thoroughly, which helps your claim process go smoothly. We also work with most major insurance companies, and we can meet the adjuster on-site to ensure nothing is missed.

For repairs or replacements, we offer a workmanship warranty that covers any issues arising from our installation. We also provide guidance on manufacturer warranties for your roofing materials, so you understand exactly what's covered and for how long.
