Slate Roofing in West Covina, CA

Slate Roof Work We Take On

We repair damaged slate, relay sound slate over new underlayment, and replace roofs that are past repair.

Repair covers the ordinary failures: a cracked or slipped piece, loose fasteners, or failed flashing. Flashing is the metal that seals roof-to-wall, chimney and valley joints. Those joints are a leading place for leaks to begin.

A full roof replacement takes the old covering down to the deck and builds the assembly back up. Between those two sits the relay, where slate comes off and goes back on over new layers.

Water can enter at one point and show up somewhere else inside. So we trace that path back to the entry point instead of patching the nearest stain.

Natural Slate or a Look-Alike

Some roofs that look like slate are quarried stone, and others are manufactured pieces shaped to match.

From the ground the two can look much the same. Up close, the difference changes how the roof is handled and how a piece is matched.

So tell us what you have, or we can look at the pieces ourselves. Matching a new piece to an existing roof is part of slate repair. Clay and concrete coverings sit in the same tile roofing family, and we work on those too.

Slate Weight and the Structure Below

Slate is stone, so the deck and framing underneath have to carry real weight.

Decking is the layer of boards under a roof covering, and framing carries that decking. Both have to handle the load of the covering above them.

Swapping a lighter covering for stone is a bigger change than it sounds. It belongs in the conversation early, before a scope is settled.

Slate does not suit every building. Where it does not, we can quote asphalt shingle roofing instead.

Repair or Relay a Slate Roof

A few failed slates point to repair; failed underlayment or decking points to a relay.

We look at the slate, the flashings, the underlayment and the deck below. Any one of them can fail while the others are still sound. What we find decides the work.

Underlayment is the sheet layer between the slate and the deck. It protects the building before the slate goes on, and again wherever a slate later breaks or slips. Which type fits depends on the slate and on the weather it has to handle.

Individual slates can be replaced where only a few have failed. The deck under them has to be in suitable condition first. Hidden rot there is one reason a quoted scope changes once the covering comes up.

A relay is the larger version of that work. We lift the slate in sections, repair damaged decking, and install new underlayment. Sound pieces go back on, and broken ones are replaced.

What a Full Slate Replacement Involves

Replacement strips the roof to the deck, then rebuilds the underlayment, flashings and slate above it.

When much of the slate field is breaking up, patching stops being the practical route. A replacement takes the covering off and starts the assembly again.

Replacement also brings the deck into the job. Boards that have gone soft come out before any new covering goes down.

Where the work needs a permit, we help property owners pull it from the city.

How We Quote Slate Work

The estimate is free, and some existing roofs can be quoted from satellite imagery without a visit.

Call (626) 593-1910 for a free estimate on slate work. Satellite imagery does not suit every roof, so a visit is sometimes the only way.

For new construction, we quote from the plans you supply. Slate work is priced from its scope, and these are the things that move it:

• How many squares the roof covers, since one roofing square is 100 square feet
• How many stories the building has, and how steep the slope runs
• Whether the old covering has to come off before new work goes on
• How many layers are already sitting on the deck
• Whether rot turns up once the covering is lifted

Roof Reports for Escrow and Insurers

A free estimate prices the work; a documented roof report is a separate paid service.

Escrow companies and insurers sometimes want the roof condition written down. That report is priced on its own, and the fee moves with roof size and stories.

If an insurer asked for it, California's insurance department publishes a residential property claims guide for homeowners.
