Why Moriarty Roofing?

I am proud to say that I was born and raised in Peterborough. Our repuation matters because our work reflects on not only the the business, but also my own personal reputation. Moriarty Roofing has been serving Peterborough and the Kawartha Lakes area since my father formed the company and our reputation for friendly, reliable, work, and attention to service is still in tact.

More Reasons for Moriarty Roofing....



​We are proud of our history and our reputation. It was once said that if you want to find a good contractor look in an old phone book. If the number is still in service, that’s a good sign. You will be hard to find a roofing company in Peterborough area that was in the phone book over 40 years ago. It doesn’t happen often, but stuff happens – especially with our unpredictable weather nowadays. You want the comfort of knowing that your roofer will be still around if you should ever need warranty repairs.




We stand behind our work. All roofing, siding, soffit, fascia, and trough repairs have a life time warranty. The reason is, if it’s our workmanship – we want a chance to make it right. If it’s due to defective products, we want to help you with your warranty claim if we can.

Attention to Detail


Most roofing companies will provide you with the option of Ice and Water shield for an additional price. Where we differ is, we provide two rows of ice and water shield because it only makes sense. Ice and water shield is designed to protect your roof in the event of an ice damn. Damming usually occurs at the point where the wall and the roof meet. Since your roof overhang is likely 18” to 24” and a single row of Ice & Water Shield is only 36”, that doesn’t leave much protection. With two rows you are protected by as much as 5’ – just in case you need it.

Do it once, do it right!
