- Walnut Heights is a Walnut Creek residential neighborhood in the 94596 ZIP code, with Walnut Heights Elementary School.
- It’s one of the higher-priced neighborhoods in the city, so some homes have premium roofing materials.
If your roof is tile, slate or standing-seam metal, tell the roofer when you call. Repairs on these materials need people with the right experience, and matching the original material is part of the job.
Premium roofs leak in different places
On a tile roof, the tiles are rarely what leaks. They’re a shield layer, and the actual waterproofing lies in the underlayment below them. Cracked or slipped tiles let water reach that layer, and when the underlayment ages, it can leak even if every tile looks intact. Slate fails when individual pieces crack or the nails corrode. Metal roofs generally leak at fasteners, seams and penetrations.
| Material | Common leak points | Repair note |
|---|---|---|
| Concrete or clay tile | Cracked or slipped tiles, aged underlayment, flashing at walls and penetrations | Tiles are lifted, underlayment repaired, tiles reset; matching tiles may be needed |
| Slate | Cracked slates, corroded nails, flashing | Specialist work; replacement slates should match the existing ones |
| Standing-seam metal | Fasteners at details, seams, penetrations, panel damage | Sealing and fastener repair; panel replacement if damaged |
Why you shouldn’t walk on tile
Tile can crack under foot, and a cracked tile that wasn’t leaking before may start to. Do not walk on a tile roof yourself, and don’t let a contractor who isn’t familiar with tile do so. Ask whether the roofer works on your specific type of roof, since inexperienced repairs can cause more harm than the original leak.
Matching what’s already there
Color and profile consistency matter on premium roofs. Replacement tiles from a different production run can look noticeably different from weathered ones, and some old styles are discontinued. A roofer may source reclaimed or closely matched tiles, or recommend spreading replacements across the roof so differences are less visible. If the leak turns out to be around flashing, the page on roof flashing leak repair explains how that works for any material.
