We're a Los Angeles-based commercial waterproofing and protective coatings contractor serving property managers, general contractors, HOAs, and industrial facilities across Southern California. Roof coatings, foundations, parking decks, and industrial floors — engineered for the SoCal climate, installed by our own crews.
Three principles drive every project we take on — and they are the reason our clients keep us on their preferred-vendor lists year after year.
We bid against a written scope of work — substrate, prep, named product, mil thickness, warranty target. The proposal you compare is the work you'll get. No vague allowances, no surprise change orders.
We only spec systems we have watched perform in Southern California heat, UV, and coastal salt air. Silicones that handle ponding, polyurethanes that survive thermal cycling, floor systems that take real forklift traffic year after year.
100% of our waterproofing, coating, and sealant work is installed by Imperplak employees on payroll, supervised by an OSHA-30 foreman every shift. No day labor. No untrained subs.
From a single failed parapet to a full multi-building roof restoration program — we cover the full envelope, above and below grade.

Learn more →A six-building East LA office park had quotes for a full TPO tear-off estimated at $1.6M. We restored the roof in place with a 30-mil high-solids silicone system and a 15-year manufacturer NDL warranty, completed across all six buildings in 13 working days.
We don't bid single-family residential. We work with property managers, general contractors, HOAs, industrial facility teams, and public-sector owners. Our paperwork, insurance limits, and field protocols are built for that world.

Read more →Imperplak restored 82,000 sq ft of TPO roof across our office park without disrupting a single tenant. Their daily photo documentation is the best I've seen from any contractor on our vendor list.
We had a deck failure two days before closing. Moses's crew was on site within four hours, identified the leak path, and had a permanent repair scope to me by the next morning. Saved the transaction.
Three other contractors quoted us a tear-off. Imperplak quoted a restoration with a 15-year NDL warranty for less than half. We're four years in and the roof is performing exactly as they said it would.
