The answer is a clear no. At Courtney Roofing Inc., we believe in doing the job right to prevent old issues from resurfacing. Often, a roof replacement is necessary because of existing problems that an old roof system couldn’t resolve. The best approach is to remove the old roof, inspect the roof deck, and address any structural issues, such as areas damaged by water. Leaving an old roof in place can compromise the new installation, leading to potential issues with water leaks, mold, or worsening existing problems. For both safety and quality, installing a new roof over an old one is never advisable.

Exposure to the sun, especially on the southern side, plays a big role in how quickly your roof ages. This is why we offer a maintenance program Roof Check for our clients. After your new roof is installed, regular maintenance can help prevent unnecessary wear over time. Just as your car requires regular upkeep, so does your roof. Constant exposure to weather means it needs ongoing care to stay in top condition.

I have a leak will I require to reroof?

The need for a roof replacement depends on its condition, age, and the level of maintenance it has received. For instance, if no regular maintenance has been done and a leak has spread, causing damage such as rotting sheathing, a full roof replacement may be necessary. To make the best decision, it’s always wise to consult with a trained, Roof Check Certified professional who can assess the situation and provide a reliable opinion before any conclusions are made.

  I have had Courtney Roofing provide services on three occasions over the recent past.  One flat roof replacement, one roof vent repair and most recently, a new singled roof on a small addition.  My experiences with Courtney demonstrate a true commitment to quality work, customer relations/service and fair/competitive  pricing.  I won't hesitate contacting them for future roofing needs.

Residential Repairs

Don’t put off roof repairs. A leak can cost you thousands of dollars to fix if there is water damage inside your home. In London, Ontario one of the most common problems is ice damming, when a blocked eaves trough causes water and ice to build up along the roofline.

Leaks can also be caused by faulty installation, weather damage or the age of shingles. If you have a low-sloped roof or a sky light, water can pool, causing leaks.
