Roofing Across the Garden City
James Roofing repairs and replaces roofs across St. Catharines for homeowners, landlords and businesses. We handle asphalt shingle roofs, flat roofs, commercial roofing, eavestrough, siding and attic insulation. Call (289) 683-9727 or request a free estimate, and we will inspect the roof and lay out your options.
St. Catharines has some of the oldest housing in Niagara. Downtown, on Western Hill and in Merritton and Port Dalhousie you find century brick homes, many with steep roofs, chimneys and more than one layer of shingles. When those roofs are torn off, sections of plank decking usually need replacing and chimney flashing needs to be rebuilt. Many older homes also have small flat sections over porches or rear additions that have been tarred over for years and need a proper membrane. We would rather fix the deck and flashing once than send you a crew every spring to patch the same spot.
The north end, closer to the lake, filled in after the war with bungalows and 1960s and 1970s subdivisions. Those homes are exposed to wind and lake-effect weather off Lake Ontario, and many are on aging second roofs with poor attic venting. Near Brock University, a lot of houses are rentals, and landlords need durable roof work done on schedule so tenants stay dry. From a single leak to a full tear-off, we will tell you what the roof actually needs and what can safely wait.

Common Roofing Problems in St. Catharines
-
Century Home Layers
Older homes often carry two or more shingle layers over plank decking. We strip to the boards, replace rot and start fresh instead of adding another layer.
-
Tarred Flat Sections
Porch roofs and rear additions are often patched with tar year after year. We replace them with a modified bitumen membrane and proper flashing up the wall.

Lake Wind Up North
Homes near Port Weller and Port Dalhousie catch storms off Lake Ontario. Secure fastening and sealed edges keep the shingles where they belong.

I am beyond happy with the work that James Roofing did at my rental property. I had water damage from an incompatible roofing system that was put on by the previous company. From the beginning of my project, James was happy to answer any questions I had about proposed solutions and always made sure I understood all options available. The job was done when he said it would be, and on time. The crew was very polite with my tenants and cleaned up 100% after their work was done. I will be calling James Roofing again when my main roof needs replaced.

Honestly great experience from start to finish. I got the run around from a few other roofers before finding James Roofing. He was prompt in returning my phone calls, worked me in a few days earlier than originally planned and fixed the leak in my roof immediately and for a fair price. Would highly recommend to anybody looking for good, honest work

Questions
Roofing in St. Catharines: common questions
Still unsure about something? Call us and talk to someone who actually works on roofs.
(289) 683-9727Do I need a building permit to re-roof in St. Catharines?
Most residential re-roofs that replace like with like do not need a building permit. Structural work, such as new rafters or reframing, may. We will confirm with the City of St. Catharines before the job starts.
Can you put new shingles over my old ones?
We do not recommend it on older St. Catharines homes. A second or third layer adds weight, hides rotten decking and makes the next replacement harder. A full tear-off lets us inspect the deck and fix problems before they spread.
Do you work with landlords and rental properties?
Yes. We coordinate access with your tenants, schedule the work to limit disruption and walk you through what we found and what we fixed, so you have a clear record for the property.
Do you do commercial roofs in St. Catharines?
Yes. We repair and replace flat and low-slope commercial roofs with modified bitumen, TPO and EPDM, and we clear commercial lots in winter. Call (289) 683-9727 for a free estimate.
