LET'S DISCUSS YOUR PROJECT REQUIREMENTS

New restaurants are constantly moving into busy areas like Downtown Washington D.C. and Old Town Alexandria. A new tenant often requires property managers to schedule alterations to their rooftops. 


All restaurants require rooftop exhaust fans and grease containment systems. Do you need to modify your roof? Let’s discuss your project details. Call us and speak with a dedicated Estimator today!

ADDING A NEW HVAC UNIT

Rooftop A/C units last a surprisingly long time with regular maintenance. However, they can also break down unexpectedly. Virginia Roofing Corporation will help you estimate costs when adding a new rooftop air conditioner. 


If your roof is under warranty, you will need to submit roof penetration details to the manufacturer for approval. Virginia Roofing Corporation will assist with this process and help you determine the best materials for your project. 


You might consider adding roof walkways pads around your HVAC unit. High-traffic areas around your rooftop equipment are more at risk for roof damage and leaks. Contact Virginia Roofing Corporation for roof walkway pad installation.

RESTAURANT AND RETAIL

Busy restaurants require a well-built commercial exhaust fan that can keep up with cooking for hundreds of customers a day. In addition, you need a rooftop grease containment system to protect your rooftop from the damaging effects of grease and oil. 


Property managers must pay special attention to grease guard containment that requires frequent maintenance. Unchecked grease is a huge fire hazard that puts everyone inside the restaurant at risk. Proper rooftop grease containment is required by law, but we still find restaurants using improper methods of catching grease. On more than one occasion, we’ve found a food-grade plastic bucket underneath the exhaust fan overflowing with gooey grease.   


Virginia Roofing will help you find manufacturer-approved restaurant rooftop equipment that fits your budget. Plus, a rooftop grease guard that is easy to clean and maintain. Contact us today!

POST-INSTALLATION ROOF CARE

Adding new equipment to your rooftop puts a lot of stress on your roof membrane. Also, contractor foot traffic, heavy equipment, and tools can easily damage your roofing system and cause leaks. Post-installation, we recommend scheduling your yearly commercial roof inspection. During the inspection, inspectors check the areas around your rooftop equipment for wear and tear.
