    Roofing St.Catharines – Dedicated Professionals Prepared to Help You

    At D’Angelo & Sons, we have been assisting St. Catharines’ residents in installing and repairing roofs for over 40 years. We are dedicated to quality workmanship and the use of quality materials because a leaky roof compromises the energy efficiency of your home, increasing heating and cooling costs. A damaged roof also compromises the structure of your home, can cause mould problems, can cause slip and fall accidents, and is a fire hazard.

    We do not compromise on quality, both in terms of materials and workmanship. We endeavour to complete all our projects on time, within budget, and to the highest quality standards. We have an in-house bin service for cleaning up upon project completion. Contact us today – we are always ready to help.

    St.Catharines Roof Replacement

    Different types of roofs have different lifespans. The roofing material will start to deteriorate when the roof nears the end of its lifespan, causing leaks and other issues. An old roof will also not be covered by the manufacturer's warranty. You also need to replace your roof if there is extensive damage, sagging (which indicates structural damage), sun damage, and leaks that will not go away.

    Some St. Catherines residents opt for DIY roof replacement, but working at heights is dangerous. Hiring a professional for the job saves you money since you do not have to buy the tools, equipment, and supplies needed for the job. With DIY, you also risk problems with your home insurer and voiding the manufacturer’s warranty. At D’Angelo and Sons, we have been replacing roofs for over 40 years. We have a strong local presence and can advise on the best roofing materials and local regulations. We endeavour to complete the project safely, on time, and within budget.

    St.Catharines Roof Leaks

    Roof leaks are caused by failure to properly maintain and inspect the roof, which leads to such problems as the caulking drying out and cracking, missing shingles, inadequate under-roof ventilation, and raised roofing nails. The age of the roof also contributes to leaking. As the roofing material ages, it starts to disintegrate. As sealant ages, it can no longer stop moisture around roof protuberances like roof vents and chimneys. Leaks can also be caused by heavy wind and rain, debris on the roof, and condensation in the attic.

    At D’Angelo and Sons, we have 40+ years of experience fixing leaks. You should call us to fix roof leaks immediately you notice them to avoid damage to the framing, slip and fall accidents, mould growth, damage to the ceiling and the attic, and electrical damage. Leak detection is not obvious. We look at the more obvious leak points, such as open seams and missing flashing, follow the stains on the ceiling, inspect the on-roof surface, and do tests using a garden hose. Our roofers are experienced, and they have the right tools and supplies to detect and fix roof leaks.

    Metal Roofs

    Metal roofs are common in commercial and industrial buildings in St. Catharines. Metal roofs are popular for their longevity, which is usually 50+ years. They are energy efficient, keeping homes warm during the winter months and cool in the summer months. These roofs are lightweight and environmentally friendly since they can be recycled, easy to maintain, and available in a variety of colours and profiles. Metal roofs are also fire, pest, and moisture-resistant. These advantages have also endeared metal roofing in St. Catharines to homeowners.
    At D’Angelo & Sons, we offer several metal roofing services to commercial, industrial, and residential clients. We do roof inspections to pinpoint the problem, after which we will either recommend repairs or replacement. We apply and reapply galvanized zinc and other coatings to metal roofs to increase their longevity. We are committed to quality, both in terms of the materials we use and workmanship. We offer an industry-leading 25-year workmanship warranty, while most other roofing companies in St. Catharines are offering 10-year warranties. Our roofers are certified, meaning you will not have a problem with the manufacturer’s warranty. We do thorough cleanup after all our projects.

    Flat Roof Repair St.Catharines

    While flat roofs give you many benefits, such as extra space, energy efficiency, and ease of installation and maintenance, they have some unique problems. The small slope prevents water from flowing away efficiently after rain or snowfall, causing ponding. Ponding is a significant risk if not properly addressed. It causes damage to the coating, destroys the membrane, causes leaks and collapse, encourages the growth of invasive plants, and weakens the structural integrity of the roofing insulation and the roof deck.

    At D'Angelo and Sons, we fix ponding issues by ensuring the drain lines are free of dirt and debris. We also fix tears and punctures on the membrane as well as leaks, blistering, and shrinkage. When you hire us, we begin with a thorough inspection to pinpoint the problem. We will then give you a customized solution and a quote. We only use the highest quality materials, which we will haul to the site in our dump trucks. All our flat roof services are executed by an in-house team – we do not outsource. We are committed to quality workmanship, timely project delivery, leaving the site as clean as we found it, and adherence to safety standards.

    Emergency Roof Repair St.Catharines

    At D'Angelo and Sons, the most common roofing emergencies we get called for are tree damage, fire damage, lightning strikes, and holes in the roof due to pest and animal damage. Other common causes of roofing emergencies are the exposure of the decking, attic space, and underlayment following high winds, hurricanes, tornados and other weather events, and ice dams.

    When you get a roofing emergency, you should prioritize your family's safety and look out for immediate danger like structural instability and downed power lines. You should then call emergency services and your roofing contractor. As you wait, take the time to document the damage for insurance purposes and to cover your belongings in heavy-duty plastic sheeting. Our operations, administrative, and accounting team is available around the clock for emergency roof repairs. We are committed to getting to the site as quickly as possible with all the materials, tools, and equipment that may be required for a permanent fix. We maintain high safety and workmanship standards when fixing your roof.

    Roofers in St.Catharines with Exceptional Values and Professional Approach

    We are a family-owned and operated business that believes in honesty, reliability, hard work, and customer satisfaction. We do not compromise on safety. Our roofers undergo regular safety training, we adhere to the provisions of the Occupational Health and Safety Act, and we have the necessary safety gear.

    I needed several windows replaced, a new side door, all siding / soffits / eaves / flashing replaced on the house, and the gables re-sided on my garage. D'Angelo's pricing was competitive - add to which, windows and doors are manufactured locally and working with a single service provider to coordinate all the activity rather than try to do that myself was really convenient.

    Very happy we decided to go with D’Angelo & Sons for our new roof. Easy quote process & was able to schedule the work in a very timely fashion, squeezing it in just before the snow came. Roofing crew were great, hardly even knew they were there and they did an awsome clean up job once the work was complete. Rochelle was very professional and a pleasure...

    D'Angelo and Sons did my roof last year and I was very pleased; they were well organized, came when scheduled and worked quickly. The roof looks great. This year, a storm damaged my roof. Carlos Vassallo came out and assessed the damage quickly and gave me an estimate. After dealing with the insurance company for months, we finally got the go ahead...

    I am very pleased with the repair to my window capping that Steve F did today. He did excellent work and took the time to fix the problem and make it look fantastic. The problem was more complicated than it looked and he was careful to both protect my siding and windows as well as replace the capping perfectly. I would also like to thank the receptionist at D'Angelo...

    We recently made the decision to fully replace our roof after losing many shingles to a windstorm. D'Angelo & Sons was very prompt in their response to our query and we had an appointment for an estimate a few days later. David was great; he was punctual and friendly. He patiently explained to us the condition of our roof and showed us pictures so we could see for ourselves. We feel secure in our decision in choosing D'Angelo & Sons for our new roof.

    When we set out to replace our roof this year, we vowed not to make the same mistakes we did the first time. We researched, asked multiple questions, and Glenn was always there for us and happy to answer any questions we had. There are many, many roofers out there, and choosing D'Angelo was the best choice we could have made. The crew was pleasant and efficient, and also happy to answer any question. We would highly recommend D'Angelo to anyone that asks. I'll be calling Glenn in the spring to discuss our eaves and fascia!

    My experience with D'Angelo and Sons was altogether positive. From my initial contact with Taylor, we were set up with an appointment with Josh two days later who gave us a full overview of what was needed and the cost. We had two other estimates and found D'Angelo to be comparable in price for the work that needed to be done. They estimated the project would start within 2-3 weeks dependent on weather and their projected timeline was accurate. Jenn was our project manager and she maintain a high level of communication with us throughout the project to ensure that we were aware of what was happening. From first contact with the company to the completion of the project, there was a high level of communication and transparency in the work they were doing. It's been almost 8 weeks since the project was complete and we've been through several significant weather events without issue. I appreciated the level of customer service that was provided by Taylor, Josh and Jenn (and roofing team) and their level of communication throughout the project.

    My sincere thanks to Steve (Sales) for your patience with all our questions and Brad (PM) for keeping us in the loop every step of the way. Chad, you and your crew did a great job to get the siding replaced and the work area cleaned up, before our backyard birthday party as promised. Rocky - thanks for going the extra mile to make sure the lighting was done just right! This is our second project with D'Angelo & Sons, which again, was delivered the project on time and on budget. More important than the asthetic improvement from the new siding (which you were right about, Steve!), the house is noticably more comfortable inside, due to the air barrier and insulation added. If I hear of anyone looking for a good contractor for roofing or siding work, I will definitely recommend D'Angelo & Sons.

    We had a massive project on our 3 storey 130year old Victorian Home. Roof replacement, siding, windows, soffits, fascia, eavestrough and other cladding and capping as required. The crews arrived on time, they worked safe at heights and steep roof pitches, they were kind & courteous, and cleaned up after each job was complete. As a home inspector, I found the workmanship to be top notch and would recommend them to any of my clients if they required work to their home.
