3 Potentially Costly Mistakes To Avoid When Replacing Your Roof

Maintaining your home requires a great deal of effort. From washing the exterior siding and outdoor living spaces to cleaning out the gutters, the various tasks required to ensure your home is clean and functional may seem overwhelming. The roof is one area of your home that requires a good amount of maintenance, as well. Unfortunately, it is not meant to last forever, even with ongoing cleaning and repairs. Considering that  it can cost you thousands of dollars to replace your roof, ensuring your roof is replaced in the best manner possible is imperative. Here are a few mistakes to avoid when it is time to replace your roof.

Mismatching Shingles

If you or your contractor purchases roofing materials and shingles from different suppliers or manufacturers, you will end up having mismatched shingles across your roof. You may end up having mismatched shingles if you are only purchasing a few new ones to replace old, worn, or missing shingles, too.

Mismatching your shingles can be a problem for many reasons. The colors will not align with the other shingles on your roof, which affects the look of your home. Different manufacturers may have different specifications for the way their shingles are shaped and sized. This means your shingles will vary in color, size, and shape across your roof, increasing the risk of leaks and water damage.

Layering Shingles

Also known as reroofing, layering new shingles on top of old ones can be helpful if you need to cut costs. Not only does this layering of shingles reduce time to repair your roof, but it also decreases labor costs because less removal is required. Unfortunately, layering shingles on top of old shingles can become a mistake if it is not done correctly.

During a reroofing, or laying of shingles over existing ones, the underlayment of your roof is not inspected and replaced. Without inspecting and replacing this underlayment, you may be leaving behind moisture that can lead to extensive water damage and even mold growth.

Reroofing with new shingles over old ones also increases the weight on your roof. This extra layer of shingles will add a good amount of weight, which places stress on not only your roof, but your home in general.

Finally, it is important to note that some states have specific building codes and regulations to follow in regards to roofing. In many instances, building codes will permit reroofing, but only two layers are allowed. Make sure your contractor pulls the appropriate permits if you are going to consider reroofing your existing roof.

Using Old Flashing

There are many components to your roof. While shingles are imperative, the flashing is also important. The flashing consists of metal pieces that are installed along and across your roof lines, helping to move water off the roof. This protects the roof and roof's underlayment from water, prolonging the lifespan of your shingles and entire roof.

Over time, the metal flashing will wear down. The sun, heat, freezing temperatures, wind, debris, rain, hail, sleet, and snow place enormous stress on the metal flashing across your roof. A lot of this stress is not very visible, so you and your contractors may decide the flashing is still in good condition as you are replacing the shingles.

You may be able to save time and money by using your roof's old flashing during the roof replacement, but this can be risky. When you are investing in a new roof, make sure to invest in new flashing, as well. This will reduce your roof's risk of future water damage.

Replacing your roof is a big expense, but it can be a great investment for your home. This guide will help you avoid costly mistakes during the replacement of your roof. Contact a company that offers roofing services for additional advice.
