Commercial Roofing Services We Offer

From large scale to small scale projects, we strive to offer a number of commercial roofing services to keep our customers taken care of, including:

Commercial Roof Replacement & Installation

Your commercial roof is one of the biggest investments for your business; we want to make sure it lasts! We work with business owners to find the most cost-effective options for their roofs. We want you to feel confident in your roof without feeling pressure to spend on roofing services you don’t need. When the time comes for a new roof or replacement, we’ll work with you to find the best solution to fit your needs.

Commercial Roof Repairs

We offer roof repairs to help keep your roof in good shape so that it will last as long as possible. Roof repairs are very effective in improving the longevity of your roof, sometimes even extending its lifespan by years. Our team can inspect your roof and let you know how much life is left in your roof as long as it’s properly taken care of. 

Commercial Roof Maintenance

Proper maintenance is another effective way to prolong the life of your commercial roof. Our team of roofing specialists can create a checklist to ensure your roof is properly maintained and that small issues don’t turn into big problems later on.

The Types of Commercial Roofs We Install

Modified Bitumen Roofing

Modified bitumen roofs can be installed with a torch-down or cold adhesive system. This is a great alternative when your commercial property has low VOC requirements. Let’s just say that modified bitumen is less smelly than asphalt heated to 425ºF, which is required for built-up roof installations.

EPDM Roofing

EPDM roofs are made of a thin rubber membrane that is durable and waterproof. This is a great material for flat or low-slope roofs and is a popular choice for businesses because it is very cost-effective. It is also quite simple to install but requires professional attention, especially if installed on a larger roof.

TPO Roofing

TPO is a single-ply membrane used on commercial roofs to protect your building from leaks. It has heat-reflective benefits and is considered a “green option” that can help your building be more energy efficient at an affordable price.

Flat Roofs

Flat roofs are durable, functional, and versatile. That’s why they are such a popular option for commercial buildings. They are also easy to maintain so you can continue your business affairs without having to worry about your roof. We’d be happy to go over the best flat roof options for your building that will fit your business needs and budget,
