Street by street
GlenEagles dates from the 1990s, so original roofs there are at replacement age, and the steep pitches make it the priciest re-roof in town per square.
Sunset Ridge, Fireside and Heartland are mostly 2010s and 2020s builds on first roofs. The question there is whether the builder's fastening was the high-wind pattern, and a roof inspection answers it before the first tab lifts.
The older streets east of downtown, around Cochrane Heights and the East End, mix eras, so the quote starts with a look at what is on the roof now.
Permits
A like-for-like re-shingle is not structural work, and structural changes are where permits attach. The Town of Cochrane's Safety Codes office confirms what a job needs, at 403-851-2573 or safety.codes@cochrane.ca, and we sort it out before the job starts.
