Look at the roofing selection at a local store or building supplier and you’ll see a LOT of choices. How do you know which product is the best for your home?
In addition to the color and style, serious thought should be given to the warranty. Below are some of the different factors you’ll need to consider with your shingle warranty.
The Basic Warranty
Regardless of which roofing shingles you choose, they should comply with government standards and have a minimum warranty that the shingle will perform as promised. Warranties usually range from 15 to 40 years, but due to advances in technology there are an increasing number of shingles available with a lifetime warranty.
While roofing shingle warranties are often considered “standard”, there can be significant differences in warranty coverages between similar shingles. Perhaps most importantly, some warranties only cover the cost of the shingles, but not the labor needed to remove the old roof and install the new one. While this kind of warranty may be less expensive up front, you will want to be clear on what is promised so you don’t have a nasty surprise later.
Also, check to see if the manufacturer will pay the full cost of new shingles or if you will only be reimbursed for the cost you incurred for the shingles you used. Prices rise. Warranties don’t always rise along with them.
It’s important to note that most shingle manufacturers have specific installation instructions. Improper installation of your roofing shingles can void your warranty.
High winds can be very damaging to shingles. Powerful gusts will rip the shingles from your roof, but even weaker winds can cause costly damage.
Shingles will lift, even if only for a second, in strong enough winds. This can be the start of two problems. First, when the shingle lifts, debris and moisture can blow in under the shingle. Once the shingle returns to its original position, it traps the debris and moisture.
If there is too much moisture, it could leak through your roof and damage your home. The trapped debris also keeps the tile from lying perfectly flat, which lets in more moisture and debris.
Wind also causes shingles to warp, which not only lets in more moisture and debris, but can also cause shingles to crack or break.
Algae Resistant Warranty
Algae growth is a common roofing problem that causes dark streaks on your roofing shingles. The algae can be cleaned away, but it will likely return, especially if you live in a humid climate. If you have had algae problems before, you should look for algae-resistant coverage on your shingle warranty.
When you’re shopping for new shingles, read the fine print carefully before you buy. Talk to a your contractor. Most have products they recommend and trust and can steer you in the direction of the best shingle for your roof.
