A roof problem rarely stays small for long. What starts as a minor leak or a few missing shingles can quickly turn into water damage, mold, and costly structural repairs if it's left unaddressed.
Some roofing companies will tell you that you need a full replacement when a repair will do the job just fine. At T. Simpson Roofing, we'll always give you an honest assessment and recommend the solution that actually makes sense for your roof and your budget. It's how we've built trust with homeowners across Barrie, Newmarket, and Central Ontario for over 30 years.
Dealing with an emergency? We aim to respond the same day or next day. Call Us Now
Your roof rarely fails all at once. Most problems start small and show up as subtle warning signs before they become serious. Here’s what to watch for:
Discolouration or damp patches inside your home are a strong signal that water is finding its way in somewhere above.
Damaged shingles leave your roof deck exposed and vulnerable. Even a small gap is enough for water to get in.
Moisture buildup in the attic is often the first sign of a roof issue, long before any visible interior damage appears.
Granule loss means your shingles are deteriorating and losing their ability to protect your home.
Flashing around chimneys, vents, and skylights is a common entry point for water when it cracks, separates, or corrodes.
Poor roof condition affects insulation and ventilation, which often shows up first on your heating and cooling costs.
High winds, hail, and ice can cause damage that isn't always visible from the ground but can worsen quickly if left unchecked.
We'll come take a look and give you an honest assessment. No pressure, no obligation. Just a clear picture of what's going on with your roof.
From minor fixes to significant storm damage, our team has the experience and expertise to handle it all. Here’s what we do:
A leaking roof needs to be addressed fast. We locate the source of the problem (not just the symptom) and fix it properly so it doesn't come back. Whether it's a single entry point or multiple areas of concern, we make sure the job is done right.
Barrie, Newmarket, and the surrounding region can see serious weather. High winds, hail, heavy snow, and ice storms can all cause significant roof damage. We assess the full extent of the damage and restore your roof to full working order and we can help with your insurance claim if needed.
Missing, cracked, or curling shingles leave your home exposed. We replace damaged shingles with materials that match your existing roof and perform to the same standard.
Flashing around chimneys, skylights, vents, and roof edges is one of the most common sources of leaks. Over time it can crack, lift, or corrode we reseal and replace flashing to stop water from finding its way in.
Flat and low-slope roofs require a different approach. We repair blistering, cracking, pooling, and membrane damage to keep your flat roof watertight and performing properly.
Damaged soffit, fascia, and eavestroughs can compromise your roof's drainage and ventilation. We repair and replace these components to protect your roofline and keep water moving away from your home.
When something goes seriously wrong, you need help fast. We aim to respond the same day or next day and we serve emergency calls across Barrie, Newmarket, and all of Central Ontario.
Less than 2% of roofing contractors in North America earn this designation. It means every job we do is held to the highest standards in the industry.
Most completed repairs are backed by a 1-year warranty so you have peace of mind that the job was done properly.
Since 1992, we've been protecting homes across Central Ontario. We know this region, its climate, and what it takes to fix a roof that lasts here.
If your roof repair is a significant investment, we offer flexible financing options to help make the process manageable.
Roof repairs can feel uncertain. Here are the answers to the questions most homeowners ask when getting started with us.
For most standard repairs, we can get you booked in on the initial call with a technician scheduled within one to three days. Larger repairs that require a sales representative to quote and supplies to be ordered are typically scheduled within one to two weeks. We'll give you a clear timeline when you call so you know exactly what to expect.
That depends on the age of your roof, the extent of the damage, and whether the issues are isolated or widespread. We'll give you an honest assessment and recommend whichever option makes the most sense for your situation and your budget.
We do our best to match your current shingles as closely as possible. Keep in mind that older shingles may have faded over time, so there can occasionally be a slight variation but we'll always let you know upfront.
It depends on the cause of the damage. Storm damage, falling debris, and other sudden events are typically covered by home insurance. Wear and tear generally isn't. We work directly with insurance providers and can help you navigate the claims process.
If we uncover additional issues during the repair, we'll stop and walk you through what we've found before proceeding. You'll always know what's happening and why. No surprises.
Yes. For emergency repairs we aim to have someone out the same day where possible, or the next day at the latest. During periods of high demand such as after a major storm when call volumes are high, response times may be slightly longer, but we work through every request as quickly as we can and we'll always be upfront with you about timing when you call.
During the March 2025 Ice Storm we had a large tree fall onto our roof. T. Simpson Roofing came to repair the roof and replace the shingles, eavestrough, soffit and fascia. His crews were very professional and did an excellent job in a timely manner. We are very happy with the results and would definitely recommend them.
We found an issue on our roof late on Friday afternoon, not a big repair job but one that was headed to a bigger issue if not repaired. We Googled roofing companies, found T Simpson, sent them a message even though we were not sure if job too small for them. They responded within the hour and had someone here on Monday morning. Service Tech was professional and courteous, everything looks like new again and problem solved before winter. Highly recommend them.
T.Simpson Roofing recently repaired a large area of our leaking porch roof by replacing the compromised sheathing, installing ice shield and new shingles . The work was professionally completed at short notice and in one day by a very knowledgeable Ken Simpson.
I highly recommend T. Simpson Roofing for their 5 STAR customer service from quote to installation. Thanks for a great job.
Very professional and a pleasure to do business with. I had my entire roof done by T. Simpson just over 5 years ago, so when the ice storm damaged my roof, I called Terry and he came over promptly to assess the damage and give me an estimate. Once I got the tree off the roof, I called back and within a week they came and completed the work in less than a day. They do excellent work and do it safely.
Tim and Ken were great in coming to my house for an emergency roof leak after a big rainfall. They came here fast after being called, and were professional, kind, and extremely knowledgeable. I will definitely contact them again for any roofing needs!
