Interlock Metal Roofing is proud to be members ​with the following roofing industry partners​.

The Interlock team was a pleasure to work with from beginning to end. Undertaking the re-roof of a 108 year old home is a major process and investment. After speaking to many other roofers, we realized that Interlock offered the best value proposition and we felt like they were going to be able to deliver on what they promised. Our salesperson, John Mondschean displayed his extensive experience in roofing, by taking the time to listen to our goals, preferences and concerns, offering solutions and working with us to achieve the desired outcome.

John was responsive every request and stuck with us even after the contract was signed. We appreciated that he was always available to answer questions, give us updates and even bringing color samples over one afternoon for us to double-check our selection. John embodies integrity and service.

Cool Roof Coating

All Interlock Lifetime Metal Roofing Systems are protected with the Alunar® Coating System.

The cool roof pigment technology helps reduce heating and cooling costs for your home.

Alunar Coasting System diagram

Interlock’s (IR) reflective surface can help reduce your attic's temperature during summertime heat, saving you up to 25% on your cooling costs†.


The Alunar Coating System is a full 70% PVDF coating incorporating a unique acrylic blend and 70% polyvinylidene fluoride (PVDF). Designed as a premium finish to provide outstanding color stability, gloss retention, exceptional abrasion resistance, scratch resistance, and chemical resistance. Alunar is also formulated to be used in coastal environments. This high-performance coating is engineered to reduce the carbon footprint and lower the heat island effect.


Alunar uses infrared (IR) reflective or “cool” pigments to comply with industry energy conservation initiatives. Using “cool” pigmented coatings can help reduce energy consumption for conditioned living spaces.
