Why this matters
What you should know before hiring any roofer
New roof installation differs from replacement in important ways. There is no tear off, no existing layers to navigate around, and often a deeper conversation about materials because the homeowner is building from scratch. American Roofing Pro works on new construction projects across LA with general contractors, architects, and homeowners directly.
ADU roofs have become a growing portion of our new install work. California has made ADU construction easier, and most LA homeowners adding an ADU need a new roof on the structure. ADUs are typically flat or low slope and integrate visually with the main house. We handle the membrane install, the flashing to the existing structure, and the inspection paperwork.
Material selection on new construction is a longer conversation than on replacement because the homeowner has more options. There is no existing roof to match. We typically walk through composition shingle (workhorse, 25 to 30 year life), concrete tile (50 plus year life, heavier, structural verification needed), clay tile (75 plus year life, classic LA look, premium price), and flat membranes (for low slope sections). The right choice depends on the home style, the budget, and the long term ownership plan.
Permits and inspections are part of every new install. We pull the roof permit, coordinate the city or county inspection at the right point in the project, and provide all the documentation the GC or architect needs for the certificate of occupancy. The permit cost and the inspection coordination are part of the written estimate.
Owner promise: An owner or senior roofer is the person who inspects your roof and writes your quote. Not a salesperson. Not a subcontractor. The same person who quotes the job is on site when the work happens.

Yes. We work as a roofing subcontractor on new construction projects regularly. Direct contracting with the GC is standard, and we handle the permit and the inspection.
Can you do an ADU roof?
Yes. ADU roofs are a growing portion of our work. Most are flat or low slope. We handle membrane install, flashing to the main house roof, and inspection.
How much does a new roof installation cost?
Depends on size, material, slope, and access. Composition shingle is most affordable, concrete tile mid range, clay tile premium. We provide a firm written quote after the site visit.
Do you do new roofs on detached structures like pool houses?
Yes. Pool houses, guest houses, workshops, and other detached structures. Often these are flat roof installs.
Will you coordinate with my architect?
Yes. We review the architectural plans, confirm material specifications, and provide product data sheets and warranty information for the project documentation.
Is there a difference between new install and replacement?
Yes. New install does not include tear off of an existing roof and typically does not require deck repair. Replacement starts with tear off and often involves deck and underlayment replacement.
