What We Do
What Our Customers Say
Hard work, and no mess
![]()
We discussed the problems I’d been having and decided that a slight slope of the flat roof towards the outside and an eavestrough and downspout would resolve my issues and it has. The team worked hard and had the job done in about two weeks. There was no mess or debris around the yard. I am truly grateful and would recommend your company to anyone who needs to have a flat roof repaired or redone.

I wish I knew about them sooner

We have hired no less than five contractors to repair our problem. All were unsuccessful I wish I knew about Sealteck Flatroofing Inc. 20-years ago.

No delays and cleaned up thoroughly

Sealteck gave us a brand new flat roof at the most reasonable price in the market. This company has a solid product, along with the insurance and expertise to install it. There were no delays and they cleaned up thoroughly before they left. Thank you Jason for understanding our situation and delivering as promised!
