Is Your Previously Overlaid Roof Telegraphing? If So, Do Something About It

by Wade Black

If you previously added a second layer to your roof, you may notice a few strange things on it, including bumps, bubbles, and even waves. These strange problems may be due to telegraphing. Telegraphing occurs when damaged shingles, rusty nails, and other imperfections on your roof show through the layers above them. Telegraphing can expose the foundation of your roof to various issues, including weather damage. Learn how telegraphing changes the structural integrity of your roof and how you can settle it below.

Why Does Telegraphing Occur?

When roofing systems age, they can disrupt the safety of your entire home. To prevent problems with weather, insects, and other obstacles, some homeowners choose to save money by using a technique called overlaying. Overlaying allows you to cover your old roofing material with new material instead of replacing it outright. Although overlaying can save you money now, your choice may not be a wise investment later.

Overlaid roofs can telegraph if they go unchecked or contain damaged or improperly installed material. Telegraphing can change the surface of your roof by making it appear bumpy, lumpy, and wavy. The old material beneath your new shingles could be saturated with water, tested by time, or even deteriorated by excessive wear and tear. If you don't remove the damaged material from your roof before you lay down new shingles, it can push through to the surface later on. 

Telegraphing roofs eventually leak or blow off during windy conditions. The exposed material beneath your telegraphed roofing shingles may also deteriorate quickly, which allows additional moisture and pests to enter your residence. You can keep these problems in check by fixing your roof properly.

How Do You Fix Your Telegraphed Roof?

The first method for smoothing out your telegraphed roof is to hire a roofing contractor. A roofer can remove the multiple layers of material from your roof and examine the surface below it. If the exposed foundation lacks integrity or shows signs of damage, a contractor can remove it and install fresh material in its place. 

A contractor can also use stronger roofing replacement material to strengthen your roof. You may choose to use asphalt, slate, or even metal material to reinforce your roof. The material chosen for your home should protect it from moisture, pests, and weather damage in the years to come.

Additionally, consider having your replaced roof inspected in the fall. Even new roofs can fall prey to freezing temperatures in the winter. An inspection helps you avoid problems before they set in.
