Outstanding Roof Work
Commercial Roofing
“JH3 successfully finished a complex TPO “cool” roof installation for one of our clients in Newbury Park. Their crew’s work was flawless when applying the white elastomeric coating. They finished three days ahead of schedule and precisely within budget. JH3 has earned our trust as a highly reliable subcontractor, and we will certainly utilize their services for future re-roofing contracts.”

Residential Roofing
“I contacted JH3 Company for a full roof replacement and was impressed from the start. They provided a quick estimate and promptly answered all my questions. Despite high demand, the work began much sooner than expected, within just six weeks. The crew was professional and incredibly careful, and my new tile roof looks fantastic! Chris maintained great communication throughout.”
