Common Types of Roofing Problems

Reputable roof repair companies in Ontario can help with the following issues.

Roof Leaks

One of the most common roofing problems is leaking, which can have many causes. Your homeowners insurance might pay for repairs if the leak happened because of an accidental event. Don't wait long to address the issue, as a roof leak can rapidly become a major and costly problem. Signs to look out for include water damage near your skylights, chimney, gutters, flashing, or vents.

Standing Water

Standing water can happen on any roof type, but it's most common on flat roofs. When collected water can't drain, it can cause algae, mold, mildew, and rot. Failure to fix the problem can lead to a sinking roof. The water can seep into your home's support system and be a health risk to you and your family.

Storm Damage

Severe storms, such as tornadoes, can cause damage to your roof.

Shingles safeguard your roof against moisture and debris. Your roof is vulnerable to wear and tear with compromised shingles. Damaged flashing is another common problem after storms. If compromised, the seams that secure your roof and any protruding structures separate. This results in several moisture problems.

Clogged Gutters

Your gutters and roof are susceptible to issues when gutters go without cleaning. The longer you don't address the blockage, the more water infiltrates your roof system. Excess debris can cause damage in your roof and harm to fascia boards.

Poor Ventilation

Your entire home needs sufficient ventilation to manage moisture and facilitate healthy airflow. Insufficient ventilation promotes issues with mold development, maintaining your home temperature. It can damage sheathing, rafters, shingles, and insulation. Inadequate ventilation can also contribute to health issues and increase your energy bills.

Factors To Consider When Choosing a Roof Repair Company in Ontario

Roof repairs can be a big cost. We recommend considering the following criteria when researching Ontario roofing companies:

  • Cost and payment options: Secure a detailed estimate up-front and discuss financing options. Ensure you understand the terms and what's included. Get any financing agreements in writing.
  • Material quality: Roofers shouldn’t cut corners. Ask what materials they'll use.
  • Past project photos: Obtaining before and after photos can help you confirm their work qualityexperience.
  • Qualifications: Ask the roofing company for proof of proper licensure and insurance before they do any work.
  • Reputation and reviews: Look at reviews on the Better Business Bureau, Trustpilot, and Google Reviews to get customer insights and find out if the company has had any legal issues.
  • Safety measures: Roofing work is dangerous, and the company you choose should put safety first. This is another reason to verify proper certifications and insurance, so the company is responsible if someone is injured.
  • Timeline: Confirm that the roofer can complete the work when you need.
  • Warranty: Quality roofers offer materials and workmanship warranties. It's important to confirm the contractor is a preferred partner and authorized dealer for the shingle manufacturer, as manufacturers often only honor warranties from approved installers.

How Much Does It Cost To Repair a Roof?

Tackle roof repairs promptly, because these are far cheaper than paying for a full roof replacement. Most homeowners pay an average roof repair cost of $856 in Ontario. Variables such as pitch, materials, roof features, repair type, and location affect pricing. Small holes and minimal shingle replacement are on the lower end, while a sagging roof and extensive roof replacement are on the higher end.
