Every commercial roof has a life cycle and there comes a point in time when it makes sense to stop repairing and replace instead. We will assist you through every phase of your roofing project, from the planning phase through the installation and well beyond. Nasi Roofing takes a holistic approach to roofing, providing complete roofing services.
If your current roofing system is older and beginning to experience chronic leaking or if the roof system is lacking insulation and not energy efficient, it may time to consider a replacement instead of a repair. A Duro-Last roof is not like most other single-ply roofs. Because it is prefabricated in a factory to reduce seams by up to 85 percent, it fits like a glove over your building's roof deck. Properly installed, it may never need repairing. When it does, though, avoid using your own facilities crew to make repairs on a Duro-Last roof.
A roof inspection is a critical part of roof maintenance and your roof manufacturer's warranty. During a commercial roof inspection, we evaluate your entire roofing system and all the components associated with it. Early detection of possible issues can save you money and add years to the life of your roof.

The best roofers around. Fast and professional with a great price and an excellent crew. I couldn't ask for better. I recommend N.A.S.I. Construction and will use them again for future projects. Service: Roof installation
