Commercial hail restoration

Diesel Works

After hail damage, Velco installed a TPO retrofit over the existing metal roof, replaced the guttering, and repainted the building exterior.

The retrofit was chosen to improve roof insulation, slow heat transfer into the shop, and suit the building’s low roof pitch.

Why Velco chose a TPO retrofit

Insulation and shop comfort

The retrofit gave Velco a way to improve insulation over the existing metal roof. The goal was to slow heat transfer from the roof into the shop.

Low-pitch drainage

Velco chose TPO for this low-pitch roof with water shedding in mind. The restoration scope also included replacement guttering.

Ease of cleaning

Ease of cleaning was another reason for choosing a membrane on this building. The project also included repainting the exterior as part of the hail restoration.
