Frequently Asked Questions

How long does a commercial roof last?

+

Most commercial roofing systems last between 15 and 30 years depending on the material, installation quality, and maintenance schedule. TPO and PVC membranes typically last 20–30 years, modified bitumen systems 15–20 years, and standing seam metal roofs 30 years or more. Regular inspections and proactive maintenance can significantly extend the life of any commercial roof.

Can you roof my building without disrupting business?

+

Yes. We understand that business continuity is a priority. Our team coordinates phased installations and works around your operating hours to minimize noise, access disruptions, and any impact on your tenants or customers. We develop a detailed project schedule with your property manager before work begins.

Do you handle permits for commercial roofing?

+

Yes, we handle full permit coordination with the City of Los Angeles and surrounding jurisdictions. Our team manages all paperwork, inspections, and code compliance requirements so you don't have to. Commercial roofing projects in LA typically require building permits, and we ensure everything is properly filed and approved before work begins.

What maintenance does a commercial roof need?

+

We recommend bi-annual inspections (spring and fall), regular drain and scupper clearing, seam and flashing checks, and coating reapplication on coated systems. A proactive maintenance program catches small issues before they become costly repairs and helps maximize your roof's lifespan. We offer scheduled maintenance programs tailored to your building's needs.
