Commercial Metal Roofing in Los Angeles, CA

Metal roofing work begins by naming the roof areas involved. Metal may cover the entire roof or only a canopy, a sloped section or an addition. Other areas of the building may use a flat roof system.

When metal is already on the roof, the job is usually a repair or a replacement of that system. If metal is new to the building, the plans should define the complete roof assembly. That includes the panels, their attachment and every layer beneath them.

Metal does not suit every roof area, since slope, deck condition and project design all affect the fit.

Panels, attachment and transitions are three separate questions in a metal roof scope, and each one changes the work.

• Panels: The panel is the visible metal sheet. Its profile, metal type, thickness and finish belong in the written scope. Some panels fasten with screws through the face, while standing-seam panels join at raised seams that hide the fasteners.
• Attachment: This is how the panels hold to the roof. It covers the clips or screws, their spacing and the deck or framing they fasten into.
• Transitions: These are the places where metal meets walls, edges, vents, equipment curbs or flat roof areas. Flashing and trim seal those places, and many leaks begin there.

The conditions on site and the panel maker's instructions set these details, not a general rule.

For commercial roof repair on a metal roof, the first clue is where the water shows up inside. Tell us when it appears, whether it follows rain and what was repaired before.

A metal roof leak can trace to loose or missing fasteners, open seams or flashing at a transition. Old patches and sealant can hide the real source, so any repair history helps.

Keep a simple leak record from inside the building. Note the date, the room or unit and the weather each time water appears. Save any photos you already have.

Leave the roof itself to us. Call (424) 842-2249 to request a free estimate for the leak repair.

Replacement and new installation are separate jobs with different risks. Commercial roof replacement removes the existing roof and installs a new system in its place.

Removal can expose deck damage that no one could see before. The proposal should state how that repair gets priced if it turns up.

Commercial roof installation on new construction follows the plans a general contractor supplies. We build the roof to those plans and do not assume what the structure can carry. Structural answers come from the plans and the people who prepared them.

When the job needs a roofing permit, we help you pull it from the city or agency in charge. Approval and timing rest with that office.

A clear proposal names the system, the scope, the transitions, the access plan and the warranties. Use this list to review each item before you sign.

• System: the panel manufacturer, product name, profile, metal type, thickness and finish.
• Scope: the roof areas included, whether the old roof comes off, and what is left out.
• Transitions: how each wall, edge, vent, curb and flat roof joint will be sealed.
• Access: how crews reach the roof, where materials are stored, and how work runs around tenants.
• Warranties: which warranty covers workmanship, which covers materials, and the written terms of each.

Check the inclusions, the exclusions and every promise in writing, and ask us about any line that is unclear. The Contractors State License Board's roofing guide gives the same advice for comparing written bids.
