Our Reviews

From the initial contact with Ryan through to the finished projects, this team of professionals were spot on. The crews were great, the workmanship flawless and the pricing was fair. The whole experience with this company was over the top. I highly recomend them.

Greg was very helpful throughout the entire process. The crew that came out was extremely polite and professional too. I would highly recommend them if you are in need of a roof repair or replacement.

Custom Contracting was great throughout the whole process, from communicating with the insurance company and making sure we were satisfied. I would recommend this company to anyone. Great customer service and always there to answer any questions!

Greg from Custom Contracting went out of his way to answer questions, bring shingle samples to our home for review, and ensured all the details were taken care of. His crew did a phenomenal job at completing our roofing project in 1 day. They were professional, courteous and cleaned up with no trace they had been there. Would definitely hire Custom Contracting again.”

Roof Shingles

Residential roof replacements and repairs in St. Catharines are Custom Contracting’s top priority. Our shingles all adhere to stringent technical specifications and requirements mandated by our motto to only bring the best of roofing shingles to St. Catharines. We are the only roofer with a WindProof shingles certification as well as a 50 year limited warranty ensuring that you have peace of mind.

Emergency Roof Repair

Sometimes, extreme weather and/or accidents happen. Custom Contracting is here to keep you covered. With an endless array of styles and colours, we can guarantee we’ll find a style to match your St. Catharines shingles. Our goal is to ensure you receive the highest standard of roofing and shingles around and that the work we do will be made to last.

Roofing Carpentry

After years of degradation, subpar shingles might cause your plywood to get wet. That is key to recognize when you do since plywood makes up the foundation for your roofing and a roof with fragile plywood is a serious hazard to your home. At Custom Contracting, we are more than willing to perform a thorough inspection to determine if a plywood replacement is necessary. Feel confident with our Custom Contracting Guarantee ensuring you that your roof will be made to last.

Metal Roof Flashing

Roof flashing is a thin layer of metal installed on roofs to direct water away from vulnerable areas of your roof such as the walls, chimney and roof valleys. At Custom Contracting, our local St. Catharines-based team will replace your roof and chimney flashing at ZERO additional cost to you. No hidden costs, no fees, simply roofing done right.

Roof Accessories

Builder-grade roofing generally has plastic vents which are vulnerable to degradation over time and eventually collapse. Custom Contracting vents are metal alloy-designed to ensure that your St. Catharines roofing stands the test of time. We’re ready to install any additional accessories out of our wide array of stock, simply contact your project manager for more info today.

Roofing Insulation

Your attic has a huge role to play in maintaining your roofing. For instance, big and expansive attics provide roofs with the ventilation key to keeping your plywood in pristine condition. After performing a thorough inspection FREE of charge, our proper insulation can help you save on bundles of energy by keeping cold air in during summers and out during winters for a better roof and a better bank account.
