This home was suffering from algae and lichen growth. There are three major types of growth when it comes to roofs which are lichen, moss, and algae. Usually when there is moss and algae present its safe to assume that there is a leak already present in the roof and the moss and algae started growing as a result, but lichen is usually the one out of the three to cause a leak due to the way the roots grow. They tend to grow deep into the shingles and penetrate the decking layer. These roots give water a path to follow that leads straight into your attic and your home.
Due to the severity of the leak, a roof replacement was needed, so that is exactly what we did. First, we ripped up the old shingles and inspected the decking layer below. There were a few sheets that were rotting from the leaks and these needed to be replaced but the rest of the decking layer was in good condition, because of this we were able to save the customer money by using the existing decking layer.
Once the rotted sheets were replaced we laid down we moved on to installing the decking tape, Sealeron Ice and Water, and a synthetic underlayment. These three layers add extra protection to the roof and they also insulate the roof increasing the energy efficiency of the home.
Finally, we can install the shingles and this customer decided on our IKO Dyansty Castle Gray Shingles. Whenever we install shingles we start at the bottom edge to make sure that they are layered properly and that water is redirected properly. Now that the shingles are installed this customer can be certain that their home will be safe and sound all year round.
