Commercial Slate Roofing in Los Angeles, CA

Request a commercial roofing estimate

We fix broken, loose and slipped slates on commercial and multi-unit buildings in Los Angeles. We also handle lift and relay, which puts new underlayment under slate that is still sound. When damage reaches too much of the roof, we prepare a separate proposal for full replacement.

Every slate job depends on three things: the slate itself, the fasteners holding it and the layers beneath. Those details show whether a repair, a lift and relay or a replacement fits the building. Call (424) 842-2249 for a free estimate on the slate work your building needs.

Start with the Existing Slate and Roof Details

Before we price any work, we confirm that the roof is natural slate. Some roofs use synthetic or composite products that resemble slate from the street. Knowing which one you have keeps the estimate tied to the right material and repair choices.

Next, we note which slates have cracked, slipped or gone missing, and we look at the nearby flashing. Flashing is the material that seals joints at walls, chimneys, valleys and roof edges. It can leak on its own, so a broken slate nearby is not always the cause.

On a commercial or multi-unit building, tell us which units or rooms show leaks. Tenant reports, ceiling stains and wet walls help us link roof damage to the spaces below.

Slate Roof Repair Depends on Fasteners and Hidden Layers

A broken slate is often only the visible part of the problem. Fasteners hold each slate, and underlayment, a layer beneath it, helps protect the roof deck from moisture. If those parts have failed, replacing a single slate may not stop the leak.

The repair scope depends on the fasteners, underlayment and flashing around the damage. The count of broken slates is only one input to that scope. The National Slate Association's article on slate roof condition assessments covers the slate, fasteners, flashing and underlayment.

Leaks that start away from the slate fall under our broader commercial roof repair work.

Lift-and-Relay Questions for Slate Roofs

In a lift and relay, we lift the existing slate and replace the worn underlayment. We repair damaged decking, the boards under that layer, and then relay the sound slate. This option fits when the slate is in good shape but the layers below it are not.

Before you approve a lift and relay, ask us these questions:

  • What share of the existing slate is likely reusable, and what happens if pieces crack?
  • Where will replacement slate come from, and how closely should it match?
  • How much underlayment and decking does the estimate include, and what does extra decking cost?
  • Does the plan cover the whole roof or certain sections, and in what order?
  • How will the work schedule affect tenants or staff in the building?

The actual count of reusable slates becomes clear only after lifting begins. If you're weighing a spot repair against a full relay, call (424) 842-2249 for a free estimate.

When Slate Roof Replacement Needs Its Own Proposal

Replacement gets its own proposal when damage spreads too far for repair or relay to make sense. We base that decision on the affected area and the work needed underneath, not on age alone. Worn underlayment or soft decking across wide sections can tip the choice toward replacement.

Removing the slate down to the deck falls under our commercial roof replacement work, with its own written proposal. Read that proposal for what it includes, what it leaves out and what it promises. A full replacement also carries our ten-year workmanship warranty.

If the job requires a permit, we help you pull it from the city or county. New buildings follow a different path: we price commercial roof installation from the supplied project plans.

Records That Help Us Prepare Your Slate Estimate

A few simple records help us scope your estimate and ask the right follow-up questions. You don't need every item, and we confirm the roof material during the estimate.

  • The building type, number of stories and how crews reach the roof.
  • Dates and scope of past repairs or relay work, plus any product names on old invoices.
  • A leak log showing where water appeared, when, and the weather at the time.
  • Photos from the ground, a window or indoors; please keep everyone off the roof.
  • Your preferred schedule, including any tenant or business hours to plan around.

After your first call, we may ask for specific photos or records.

Slate Roof Cost, Report and Warranty Questions

What is the average cost of a slate roof?

A commercial slate roof has no single average price. The quote depends on roof area, condition, the layers specified, tear-off, access and the full scope. The estimate for the work is free; a detailed written report carries its own fee.

What are the drawbacks of a slate roof?

Fasteners and underlayment can fail under slate that looks fine, so one new slate may not stop a leak. During a lift and relay, some slates may crack, and the reusable share stays unclear until lifting begins. For replacement pieces, ask where they will come from and how closely they will match.

What warranty applies to a full replacement?

Our ten-year workmanship warranty applies to full roof replacements only and is separate from any manufacturer warranty. Ask for the written warranty terms before you sign the replacement contract. For repair or relay work, ask what written terms apply.
