“We recently completed a room addition along with a full roof customization, and the results are amazing. The team was professional, organized, and easy to communicate with throughout the entire project. The new room looks like it has always been part of the house, and the new roof was installed perfectly. Highly recommend their services!”

Low-slope systems specified for the building, not the brochure
Most commercial and multifamily roofs in Los Angeles are flat or low-slope, and the failure points are consistent: ponding, seams, penetrations and flashing at parapets and equipment. We assess the existing assembly, drainage and insulation, then recommend the right system — TPO or PVC single-ply, modified bitumen, built-up roofing, a restorative coating where the deck is sound, or standing-seam metal.
Work is scheduled around tenants and operations, permitted with LADBS or the local city, and specified to meet Los Angeles Class A fire-rating and Title 24 cool-roof requirements. As a general building contractor we also handle the deck repair, parapet and drain work that a re-roof frequently uncovers.

Commercial roof repair in Los Angeles
Not every commercial roof needs replacing. Most calls we take from building owners and property managers in Los Angeles are leaks with a specific cause: an open seam in a TPO or PVC membrane, blistering or splitting in modified bitumen, ponding water at a low spot or a clogged drain, failed flashing at a parapet, curb, skylight or HVAC penetration, or damage left behind by a rooftop equipment contractor. We trace the source, photograph it, and put the repair in a written scope before anyone starts cutting membrane.
Where the deck and insulation are sound but the surface is aged, a restorative coating can extend the life of the roof for far less disruption than a tear-off. Where the assembly is saturated, coating over it only hides the problem — and we will tell you that. Repairs, coatings and full replacement are all priced from the same written assessment so you can compare the options against how long you plan to hold the building.
Working around tenants and operations
Occupied buildings set the schedule. We stage material and equipment where it does not block parking or access, sequence the work section by section so units and suites stay usable, coordinate noisy phases with building management, and give tenants notice before anything above their ceiling is opened up. Permits and inspections are handled under CSLB #1155602 with LADBS or the city building department that has jurisdiction over the address.

What homeowners say
“I didn't think a bathroom could make that much of a difference until this one was finished. We kept the design pretty timeless with a walk in shower, porcelain tile, and a wood vanity, and it completely changed the feel of the space. It feels cleaner, more open, and just a lot more enjoyable to use every day.”
“Great experience with American Reliable Construction & Remodeling. They helped us with our ADU from start to finish and made the whole process smooth and stress-free. The team was professional, responsive, and delivered quality work. Highly recommend!”
