SentinelSeal™ | Sentinel

Flat roofs can often be restored with a spray-applied coating system, but only if the owner acts before major damage occurs. This solution is ideal for roofs that are still structurally sound but starting to show signs of wear.

Cost Savings

Roof coatings can save 40–60% compared to full tear-off and replacement.

Warranty

Most systems come with a 20-year manufacturer warranty, offering long-term peace of mind.

Timing is Critical

Coating is only an option if applied before leaks or deterioration become severe. Waiting too long eliminates this cost-effective option.

For flat roof owners who act early, spray coatings provide a high-performance, long-lasting, and budget-friendly alternative to replacement.

If you’re eligible, you could extend your roof’s life by up to 20 years with our spray coating solution for nearly half the cost of replacement. When business budgets are tight and disruption isn’t an option, SentinelSeal provides the breathing room you need.
