The roofing industry has changed quite a lot over the years. These days, homeowners are rarely opting for the standard, 3-tab shingles that were so popular a few decades ago. Instead, they are going with architectural shingles, and in some cases, with even more eco-friendly options like green roofing or slate. Whether you're shopping around for a new roof or are thinking of having repairs made to your current roof, it pays to be educated. Learn the basics on this blog, where we discuss roofing in the modern world. We explore various roofing materials, roofing techniques, and how to find the right roofer.
The roofing contractor you hire to replace your roof is there to serve your needs and do everything in their power to ensure you receive excellent service, but there are some things that the contractor cannot do for you. The goal of the contractor is to ensure you have a structurally sound roof to protect your home, so anything that goes against this goal is a no-go. Learn about some of the things your contractor will probably not do.
1. Keep Old Shingles in Place
Replacing a roof is an investment, so some homeowners often look for ways to save money. One seemingly feasible way to go about the process is to skip the demo and keep the old shingles in place. Unfortunately, a contractor cannot always do this for you. When you install new shingles over old shingles, you can create pockets for moisture accumulation. The pockets of moisture can break down the new shingles and open the door to water intrusion concerns.
2. Forgo Moisture Protection
Shingles are important, but they are the last step when it comes to moisture protection. To keep moisture out, you need to also install a moisture barrier under the shingles. Again, while being cost-conscious is important, a contractor will not attempt to help you save by forgoing this protection. You might save upfront, but if you do not have this barrier installed, your new roof will not last very long and you can look forward to significant water damage inside your home.
3. Reuse Flashing
Flashing is the thin layer of metal you often see around dormers and chimneys or any other place where a roof pane meets another surface. The goal of this addition is to keep water out. Flashing has a lifespan that is very closely aligned with the lifespan of roofing materials. That being said, when you replace the roof, you need to replace the flashing. Subsequently, a contractor will never reuse the flashing on your roof.
4. Not Address Repairs
Sometimes installing a new roof is only a part of the solution. With a very old roof, there may be issues with the roof's structural support system. As long as this damage remains, the integrity and durability of the roof will constantly remain in question. A qualified contractor will not simply ignore this damage and move forward with the install. Instead, they will ensure that the roof is in good condition to ensure the replacement is complete.
When you work with a professional roofing replacement contractor, you can rest assured that your new roof has been installed correctly.
