Walnut Creek Roofers installs and repairs natural slate roofing, and the first thing we tell a homeowner is that slate outlasts almost anything else you can put overhead. It sheds winter storm systems, shrugs off the hail that rolls through on hot summer afternoons, and holds its own against the strong afternoon winds that push across the Diablo Valley.

Slate roofing is a layered assembly built for hot, dry summers with occasional hail and for winter rain systems. Slate tiles sit over a self-adhered ice-and-water shield at the eaves, synthetic underlayment across the field, plus copper flashing at every valley.

Each tile gets fastened with ring-shank nails into solid decking, because one slate square weighs several times what an asphalt shingle does. Strong afternoon winds matter here too; wind uplift pulls at the rake and ridge first.

Cost on a slate job is driven by how much needs a full tear-off, whether the decking shows rot, and how much flashing has to be custom-bent. A recover or overlay over failed slate almost never works, and we'll tell you that up front.

What's Included

A full roof inspection from the ladder line, checking tile condition, flashing, and the ridge cap before we quote anything.

Tear-off of failed slate in the repair zone, with the debris hauled away in a dumpster we set on the driveway.

New synthetic underlayment and ice-and-water shield wherever the old felt or tar paper has dried out and cracked.

Custom-bent copper or steel flashing at the valley, chimney, and any skylight, formed on site to match your existing profile.

Replacement tiles matched to your slate and fastened with ring-shank nails, hand-sealed along the head lap of each course.

Gutter and downspout cleaning so slate flakes and debris stop backing water up under the eave and soaking the fascia.

A written line-item roof estimate broken into labor, material, and any decking repair, so you can see what drives the number.

Signs You Need Slate Roofing

Slate flakes and gritty crumbs piling up in your gutters after a windy week, which is granule loss on a much larger tile.

Hairline cracks or chips across the roofline after one of our summer hail events, usually starting on the south-facing slope.

Rusted or popped nails showing at the rake and ridge, meaning fasteners have backed out of the sheathing underneath.

Brown stains on attic rafters or a damp smell near the chimney, a sign water is wicking past the counter-flashing.

A sag or dip in the roofline, which points to rotted roof deck or a purlin that has settled under the weight.

Green or black streaking that will not wash off, common on north slopes that stay damp through the winter.

Our Slate Roofing Process

We start with a roof inspection from the ground, then the ladder and, if needed, scaffold — checking the field, ridge, valleys, and chimney flashing before we quote a thing.

You get a written roof estimate that separates labor, material, and any decking repair, so the cost adds up in front of you.

On work day we set the dumpster, lay tarps, and stage material on the ground; no slate gets dragged across your finished roofscape.

Failed tiles come off with a roofing shovel and pry bar, and we cut open only what the repair needs. If we find rot, we stop and show you photos first.

Fresh underlayment goes down, then tile is set in staggered courses with ring-shank nails and a mastic seal at the head lap.

We refit the ridge cap, clear the gutters, and walk the roof with you so the job is signed off before we leave.
