Thinking about adding a deck? Don’t look any further than Cosmo Roofing and Home Exterior. From the first design consultation to final inspection, they took care of everything—including the permit process, which can be a headache. Our new deck is not just beautiful—it’s structurally solid, well-designed for entertaining, and adds major value to our home. The team communicated well and stuck to our timeline. If you want a custom outdoor living space done right, this is the crew to hire.

The absolute worst company I have ever worked with!!! I gave 70% down payment and 4 and 1/2 months later the job is still not done. I had to hire another company to do the job and Mohib has yet to issue a refund. Watch out for these fraudsters. They also threaten to sue anyone who leaves negative feedback and tries to force it to be removed but I refuse to be bullied.
