Roofing is the trade that keeps water, wind and heat out of a building, and it is one of the most failure-sensitive scopes on any project — a roof that leaks or blows off undoes the work of every trade beneath it. Roofing contractors install and service low-slope commercial systems (single-ply TPO, PVC and EPDM, modified bitumen and built-up roofs), steep-slope residential systems (asphalt shingle, metal, tile and slate), and the flashing, insulation, drainage and waterproofing details that make the assembly perform. This directory lists roofing companies across North America — browse by region, compare firms, and shortlist the ones whose system expertise, manufacturer certifications and warranty backing fit your project.
Every listing links to a full company profile with contact details, service areas, trade categories and, where available, certifications and year founded. Because roofing systems are chosen for local climate — hail, wind uplift, snow load, UV and freeze-thaw all drive the specification — the regional pages are the fastest way to find firms that build the right assembly for where your project sits.
What roofing contractors actually do
The trade divides by system and by building type. Commercial low-slope roofers work with membrane systems and are usually certified by the manufacturer whose warranty they install — a distinction that matters, because a 20- or 30-year system warranty typically requires a certified applicator. Steep-slope and residential roofers handle shingle, metal and tile, where flashing detail and ventilation determine how long the roof lasts. Restoration and service firms focus on repairs, recoats and storm response rather than full replacement.
Choosing a roofer is about matching the system to the exposure and the firm to the system. Manufacturer certification, wind-uplift and hail ratings, safety record for fall protection, and a track record of standing behind warranty work all belong in the evaluation. On re-roofs, experience keeping a building watertight and operational through the work is as important as the install itself.

Frequently asked questions
What does a roofing contractor do?
A roofing contractor installs and services the roof system that keeps water, wind and heat out of a building - low-slope commercial membranes (TPO, PVC, EPDM, modified bitumen, built-up) or steep-slope residential systems (asphalt shingle, metal, tile, slate) - along with the flashing, insulation, drainage and waterproofing details that make the assembly perform.
Why does manufacturer certification matter for commercial roofing?
On low-slope commercial roofs, the long-term system warranty (often 20 or 30 years) usually requires a manufacturer-certified applicator. Using a certified roofer is what makes that warranty valid, so it is one of the first things to confirm when the roof's expected service life is part of the value of the project.
How do I choose the right roofing contractor?
Match the system to the exposure and the firm to the system. Check manufacturer certifications, wind-uplift and hail ratings for your climate, the firm's fall-protection safety record, and its track record of standing behind warranty work. On re-roofs, experience keeping a building watertight and operational through the work matters as much as the install.
Does climate change which roof system I should use?
Yes. Hail, wind uplift, snow load, UV exposure and freeze-thaw cycling all drive the specification, which is why the same building might get a different roof assembly in different regions. The regional directories are the fastest way to find firms that build the right system for your local conditions.
What is the difference between roof replacement and roof restoration?
Replacement removes and rebuilds the roof assembly. Restoration and service firms focus on repairs, recoats and storm response to extend the life of an existing roof rather than replacing it. Which path makes sense depends on the roof's age, condition and remaining warranty.
