Sentry Roofing is a Commercial & Industrial roofing contractor specializing in flat, low-sloped, and metal roofing systems for new or active facilities.
Every roof has a life cycle and there comes a point in time when it makes sense to stop repairing and replace instead.
Because a roof installation is often a large, capital expense, we realize that building owners and facility owners need to feel comfortable in their decision.
Our job is to help you feel comfortable moving forward with the installation.
Sentry Roofing will provide an honest, thorough evaluation in writing, as well as details and photographs of any issues noted on your rooftop.
We will guide you on the best option based on your budget, building structure and need.
Project logistics, site safety and any other concerns regarding construction will be addressed, as well as the estimated timeline and project completion date.
Different roofing materials and roofing systems will result in different lifespans.
The general lifespan of a new rooftop that is professionally installed can range from around 15 to 35 years with proper maintenance and care.
A neglected rooftop can start to have problems much sooner than this if not careful.
