Yes! All Collis roofing contractors are certified by all major roofing manufacturers.
How long has Collis been in business?
Since 1991, over fifteen years now!
Does Collis subcontract their labor?
NO! All of our roofing professionals are employed by our company! Occassionally we bring in subcontractors for woodwork etc..., but all of our roofers are Collis employees.
Will Collis be removing my current roofing system?
In some cases we may remove the current system and in some cases we may not. It all depends on what we find when we take a look at the current wear and tear.
