Preparing a Roof Deck and Deciding What to Do with It

Preparing a Roof Deck

Whether you decide to replace the entire roof, part of it or to roof over whatever is already in place, you will need to prepare the deck in the best way possible. The reason for this is that the durability and appearance of the new roof is partly determined on the quality of the actual deck. When you prepare the deck, make sure to do relevant things in the right order, i.e. before the new roof goes on.  For an example: maybe you and your wife have been discussing installing a new skylight or looking to have ridge ventilation installed. Make sure to do these changes before installing the new roof shingles in order to achieve the best possible results. If you are planning for a tile roof, install any TV antennas before the roof work starts. On the other hand, if you are looking to install solar panels – make sure to lay the new roof first as solar panels goes on top of the roof. If you need smaller jobs done such as installing new gutters or repairing them, maybe adding new drip edges – try to have this done at the same time as the roof decking work are being done. The reason for this is that new drip edges should always be installed to go along the eaves before you lay the underlayments and along the rakes after it has been done.

Deciding the Best Way Forward

When you are planning to re-roof, many people wonder whether they should tear of the existing roof or roof over it. This is probably the first decision you will have to make. Now, if you are not a professional roofer, it might be difficult to decide what the best option is. The easiest option is obviously to use the existing roof as the deck for the new roof. This option will not only save you time and a lot of hassle not having to strip the old shingles off but it also provides an extra layer of insulation which will save you on heating costs. However, whether you can roof onto the existing roof or not depends on a few things.

  • Check the condition of the existing surface and sheathing
  • Check whether the old and new roof surface materials are compatible
  • Check how many roofs the building already supports
  • Check the manufacturer’s recommendations for the material you want to use
  • Check all the local building codes and requirements in your area
