Roof Shingle Replacement: Four Things To Keep In Mind

Posted on: 31 August 2020

It is a huge decision to replace your entire roof, but it is also a decision that often needs to be made at some point in time. When the time comes for this decision to be made, you must ensure that the roof shingle replacement is done right so that new problems are not created and you are able to get the most out of your new roof. Here are four things that you should keep in mind as you go about replacing your roof shingles.

Do Not Install New Shingles Over Your Existing Roof

Years ago, it was not at all uncommon for homeowners to install new shingles over the old shingles. However, over time, it has become known that this is actually a very bad move to make. In doing this, you are prevented from performing repairs that are needed below the older shingles, making it more difficult to locate and fix leaks that develop down the road. In addition, adding an additional layer of shingles to the roof adds extra weight to the overall structure. Another issue that results in installing another layer of shingles is shortening the lifespan of the new shingles.

Avoid Skimping on the "Extras"

There is a lot more to developing a solid roof barrier than the shingles. For instance, you also require felt underlayment, flashing around the chimneys and vents and in the valleys, and a drip edge along the eaves. When these extra items are skimped on or not correctly installed, the shingles can fail early on and leaks can occur. Therefore, you will want to ensure that the roofing contractor you are working with uses them.

Inspect and Repair the Decking

Over the time it takes for your roof to need to be replaced, there is a good chance that your roof deck suffered some damaged. In order to determine the condition of the roof deck wood, the roof will need to be stripped down completely. At this time, the entire decking needs to undergo an inspection so that any broken or rotted wood can be replaced.

Don't Forget the Attic Ventilation

To ensure that your roof lasts as long as possible, the attic will need to be ventilated. In doing so, you will minimize the temperature that builds up beneath the shingles as well as the excessive overheating that can occur over time. In terms of attic ventilation, this refers to the installation of attic fans and a whole-home ventilation system, in addition to proper insulation.
