How Should a Sagging Roof Be Fixed?

Sagging roof

Your roof protects your home from extreme weather conditions like high winds, flooding, and heavy snowstorms. Depending on your roofing material, a roof can last up to 50 years or more. However, roof issues can still arise. 

If you notice curves, dips, line slags, or a not-so-straight roof, you may have a sagging roof. Many factors can lead to a sagging roof, ranging from the wrong materials to age, improper installation, and more. 

A sagging roof doesn't always pose an immediate threat, but it's still an issue homeowners should take seriously. For fixing a sagging roof, you'll want to call for professional storm damage repair services in Atlanta, GA. 

Sagging Roof Causes

Let's look at common causes of sagging roofs and how to fix them: 

Water Damage

One of the main functions of roofs is to safeguard your home from problems like heavy rains or snow. However, a poorly maintained and designed roof can quickly lead to water damage and mold growth on your roof, exterior walls, and more. 

Shingles and similar materials allow for water to run off. Inspecting your shingles at least once a year is essential, with many experts recommending it twice a year. You'll also need to install any metal flashing on your roof's junctions and valleys to redirect water. 

Two other factors can contribute to this water damage and, as a result, your sagging roof: 

  • Your gutters: Clogged or broken gutters cause water to pile up, seeping inside your home. 
  • Poor ventilation: When your attic lacks proper airflow, moisture builds up under your roof. This extra moisture creates more water permeation. This process also quickens the deterioration of your shingles due to summer heat building up. 

To fix the sagging, homeowners can install angled braces to support weak or undersized rafters. Attaching chains to your wall plates, linked with a turnbuckle, also offers a solution. 

However, your roofing contractor may need to use jack posts if you have a severely sagging roof. 

Weight-Related Sagging 

Contractors design your roof to handle a maximum weight; anything beyond this can trigger sagging. For many roofs, too much snow and ice cause sagging. 

To prevent excessive ice and snow, have a professional team clear away your roof regularly. While you can try handling the issue yourself, many safety risks exist. Additionally, you can end up damaging your roof more. 

Inherent design flaws can also lead to weight-related sagging, like: 

  • Undersized rafters 
  • Not enough rafters or collar ties
  • Improper sheathing

Many solutions exist, and a roofing contractor can help you find the right one. For example, you may need to install new rafters or reinforce your current sheathing. Your existing shingles may even be too heavy for your roof, so you may need to replace them with a lighter material.
