4 Common Causes for Leaks in Metal Roofs

1) Poor Installation:

The first thing you should always do when you have a leak is to check the roofing material and make sure that it is installed properly. If you have a metal roof, then the first thing to check is to make sure the nails are not missing and that they are not hitting any of your shingles. A leak can occur if there are too many nails in one spot or if they are too close together. If this is the case, water will be easier to penetrate through the shingles and into your home.

2) Weather Conditions:

If your home is located in an area where there is frequent rain or snowfall, then your metal roof may be susceptible to leaks due to weather conditions such as wind gusts and heavy rainfall causing water runoff which could lead to leaks in your home's interior walls or ceilings.

3) Damaged panels or shingles:

Damaged panels or shingles can lead to leaks in your metal roofing system. When there is damage to a panel or shingle, it will not be able to protect the underlying structure from weather damage like hail storms or high winds that could cause leaks in your metal roofing system if they strike unprotected parts of your home's exterior walls.

4 Tricks To Find Leaks in Metal Roofs:

1) Look for water stains on your ceiling:

If you have a leak, you'll see water stains on your ceiling. These stains will be in a circular pattern around the leak, and they'll be darker than the rest of the ceiling.

2) Listen for dripping sounds:

Metal roofs are often placed over concrete patios or decks, so if there's a leak, you'll hear it dripping onto something below - usually into buckets or pans placed under the problem area to catch the water.

3) Check for dampness on walls and floors:

You may notice damp spots on walls where water has seeped through cracks in flashing or around electrical outlets or pipes that penetrate through your roof's surface layer of shingles (called torn-off tabs).

4) Use a moisture meter:

Moisture meters can help you locate potential problems in your roofing system before they become major issues. They work by measuring how much moisture is in the air around them, which makes them ideal for detecting water leaks inside your home or business. Since metal roofs are particularly susceptible to water damage, this is an important tool for any metal roofer!
