Cover board installation

If your cover board is being used it is installed over the insulation to provide you additional protection and stability for the roofing system. The cover board is basically secured to the insulation using adhesive for mechanical fasteners and is cut to fit around penetrations

TPO membrane installation

The membrane is rolled over the prepared roof surface and experts can permit it to fit around your edges and penetrations; generally you need to know that the membrane is heat welded or either to the underlying layers using a hot air gun. Experts will take special care to ensure seams are properly sealed to prevent water infiltration.

 Flashing details

Flashing details like grips, edges , edge material and penetration flashings are installed to provide you additional waterproofing protection at vulnerable areas of the roof. The flashing details are basically made of metal or TPO material and they can be secured in place using fasteners

Final touches

Once the membrane and flashing details are installed any remaining finishing touches like sealing seams applying protective coatings are completed to ensure the roofing system is completely watertight and durable. Our final inspection will be conducted to verify the integrity of your installation and address any potential issues.

So above all you need to know that proper installation is very important to ensure optimum performance and longevity.
