Receiving a new roof installation is quite an investment, so it’s a prudent move to ensure certain warranties come with it.

Anything from defective materials or improper installation may lead to rapid despair of your roof, with the other house components to follow. However, it’s never a bad idea to keep track of the fine print of a warranty, as a simple repair or upgrade to your home’s exterior might void it altogether.

If you don’t have the contract in front of you right now, then check out these common reasons a roofing warranty faces rejection.

Installing the New Roof Over an Old One

In some cases, installing a new roof over an existing layer can be labor and cost-effective. However, having multiple layers may void your roofing warranty.

Two layers of shingles add weight, bearing down on the structure and wearing down its integrity. Heat expands more slowly with a double layer of shingles, decreasing the overall lifespan of your new install.

In short, the upfront labor and cost savings might not outweigh the financial repercussions down the road.

Adding Skylights

Skylights are an excellent way to add comprehensive natural light to any roof. Unfortunately, installing a skylight window might void your roofing warranty.

Any roofing project that requires significant structural work is shaky grounds for a warranty as leaks and issues have a greater chance of arising more often.

Installing a Satellite Dish

Installing satellite dishes is a general way of plugging a lot of entertainment into your home, but your roofing warranty may have some stipulations. Much like skylights, satellite dishes and antennas may compromise the integrity of your roof, resulting in a failed warranty request.

In some cases, your full warranty won’t be rejected, just the areas where the antenna or satellite sits.

Improper Installation

Manufacturers of roofing materials have quite specific warranty rules for installation. Anything from the length of the nails to the number of nails per shingle may account for a voided warranty. Avoid DIY roof repairs, as they can void your warranty and end up costing you more money in the long run.

So, to keep your warranty in check, be sure to find and contact a reputable exterior contractor dedicated to craftsmen-level installation.

Pressure Washing

Never try to clean your roof with a pressure washer. Not only is this very damaging to your shingles, but it can void your warranty. Shingles are not designed to withstand that amount of pressure at close range, and power washing can dislodge granules that protect your roof from UV ears. If you need your roof cleaned, call a professional roofing company to clean it properly.

Improper Ventilation

A critical part of your roof is proper ventilation. This helps your roof last as long as possible. Ventilation works by allowing a continual flow of air through the attic, which prevents moisture accumulation and hot roofs. If you don’t have proper ventilation, then your roof can suffer:

• Too hot roof, which overheats the shingles
• Mold and mildew growth
• Ice dams

These problems can void your roof warranty.

What Should Your Roofing Warranty Cover?

Most roofing warranties last around 25 years, depending on the materials and shingle manufacturer. Companies like Trinity Exteriors provide workmanship warranties that cover anything that we might have done wrong or overlooked during the installation process. Manufacturer warranties will cover any defects or problems that occur during the manufacturing process.

If you aren’t sure if your roof’s damage is covered under warranty, call a professional to determine if the problems are a result of manufacturing or workmanship problems.
