Common Types of Roofing Problems

Ontario roofing companies can repair roof problems such as leaks, standing water, storm damage, clogged gutters, and poor ventilation. Keep reading to learn more about common roofing issues.

Roof Leaks

Leaking is among the most common roofing issues homeowners face. Your homeowners insurance might pay for repairs if the leak happened because of an accidental event. Don't wait long to fix the issue, as a roof leak can quickly turn into a major and expensive problem. Water damage around your vents, flashing, gutters, skylights, or chimney is a common sign of a leak.

Standing Water

Standing water can happen on any roof type, but it's most prevalent on flat roofs. When pooled water doesn't drain, it can cause algae, rot, mold, and mildew. Failure to fix the problem can result in a sinking roof. The water can leak into your home's support system and pose a health hazard to your family.

Storm Damage

Severe weather, such as tornadoes, can damage your roof.

While one or two missing shingles may seem insignificant, shingles safeguard your roof against water and debris. Without that protection, your roof is more susceptible to wear and tear. Flashing can also be compromised by storms. This separates the seams between your roof and any protruding structures, leading to moisture penetration.

Clogged Gutters

Leaving your gutters clogged isn't good for them and your roof. Water gets built up into your roof system the longer your gutters are blocked. Excess debris due to clogged gutters can cause roof holes, leaks, and damage to fascia boards.

Poor Ventilation

Sufficient ventilation throughout your home regulates moisture and allows for healthy air circulation. Inadequate ventilation promotes issues with mold development, regulating your home temperature. Potential consequences include damage to rafters, sheathing, insulation, and shingles. It may also lead to higher energy bills, and your family may experience health issues.

Factors To Consider When Choosing a Roof Repair Company in Ontario

Roof repair can be a big expense. Evaluate the following factors before choosing a roofing company:

  • Cost and payment options: Obtain a detailed quote up-front and ask about the financing options they offer. Ensure you understand the terms and conditions and get any agreements in writing.
  • Material quality: Making sure the roofer is using the quality materials for your project is important. Find out what materials they'll use.
  • Past project photos: Getting before and after photos can help you confirm their skills.
  • Qualifications: Ask the roofing contractor for proof of proper licensure and insurance before they perform any work.
  • Reputation and reviews: Search companies online, such as on Trustpilot and the Better Business Bureau, to get a sense of their work quality and if they've had any legal issues.
  • Safety measures: Roofing work is dangerous, and the company you choose should focus on safety for everyone on the jobsite. This is another reason to verify proper certifications and insurance, so the company is responsible if someone is injured.
  • Timeline: Check that the contractor can finish the work on time.
  • Warranty: A reputable roofing company will provide materials and labor warranties. Ask if the contractor is a preferred partner and authorized dealer for the shingle manufacturer—most manufacturers only honor the warranty if an authorized installer installs the roof.

How Much Does It Cost To Repair a Roof?

Fixing your roof is typically far cheaper than getting a new roof, so don't delay repairs until the problem becomes severe and you need a full roof replacement. Most homeowners pay an average roof repair cost of $839 in Ontario. Factors such as pitch, materials, roof features, location, and repair type influence your final cost. Minor punctures and replacing a few shingles are on the price range’s lower end, while a sagging roof and a full roof replacement are on the higher end.

Frequently Asked Questions About Roof Repair in Ontario

How long does it take to repair a roof?

Roof repair timelines depend on the issue and size of the project. Most residential repairs finish within 12 days. Bigger commercial buildings may need more time.

What kind of license should a roofing contractor have?

Roofers need a state general contractor or roofing license with the Contractors State License Board if the state mandates it. Not all states require roofers to have licenses at the state level, but they may at the local level, so check with your municipality.

What should you do if your roof starts leaking?

Contact a professional roofing company as soon as you see a leak. Avoid trying to release the leak yourself. Have a contractor visit your home immediately to survey and remedy the issue.

What’s the best roofing material?

The most durable and long-lasting roofing materials include clay, metal, concrete, cedar, and slate. Metal roofs have become more popular recently because of how well they hold up to wear and tear. Talk to a roofing specialist about the best roofing material for your home.

How can you tell if a roofing company is legitimate?

Any reputable roofing company will have no issue showing it's licensed and insured. Many quality service providers obtain a license with the local Roofing Contractors Association. Reading customer reviews and looking at photos of previous work can also help you assess the company.
