What We Offer

Sealed Tite


Make sure that your roof is Sealed Tite!


Your home and your possessions are only as safe from the elements as the roof that protects them. A leaky roof can rot your roof deck and rafters, cause mold and mildew. By the time you start to see wet spots on your ceilings and sheetrock, chances are mold is not far behind. Don’t wait for a small problem to become a major problem. Here at Sealed Tite Home Improvements, we sell and install the finest roofing products from GAF and Owens Corning, including GAF’s famous lifetime roofing systems in all colors and styles. Call or email us to set up a free roof inspection. If your roof is fine, then you can sleep tite; if not, you can be sure that Sealed Tite can solve the problem.
