Don’t forget…Chimney’s are Part of Your Home too!

Homeowners tend to maintain only what can be easily seen. It’s not until a problem develops do we realize there’s a roof on the house. What can be even worst is the lack of attention given to a chimney.

There are different types of chimneys on roofing systems.  I thought I’d focus more on the more common brick chimney.

Brick chimneys are an important part of your home maintenance due to the moisture and condensation brought out by the heat and air conditioning from the inside and the heat and cold temperatures from the outside.

The brick chimney has a metal counterflashing installed at the base of the chimney for protection. If the counterflashing is not cut into the mortar joint the caulking will loosen and moisture will make its way inside of the building. If the flashing is not constructed of aluminum, painted steel or galvanized steel, over time it will rust. If you’ve ever touched rust, the orange color steel particles end up on your fingers. Ultimately, it will run down your roof and stain the shingles. That is an undesirable sight.

Showalter Roofing sprays the chimney with a seal coat or silicone so the chimney remains water resistant. Some bricks are more porous, and will absorb additional water than other bricks.  The chimney cap is made from concrete that too can break up over time.  If water gets its chance to get inside the chimney cap, the chimney will need to be tuckpointed or completely replaced. A costly issue.  There are coatings which protect against water penetration called Crown Coat, a great product that Showalter frequently uses.

This summer, be sure to look on top of the roof. Be sure to check your shingles and the chimney.


Algae, Algae Everywhere!

Algae has been an issue since the develpment of fiberglas shingle.

Algae has been an issue since the development of fiberglass shingle.

Over the past 20 years more and more roofs have been attacked by an algae that has always been around. It was not imported from another country and our climate is pretty much the same as it has always been.  So where did this creature from the black lagoon come from? This black or green staining on roofs has been the source of frustration for many of us homeowners. We have this beautiful home and landscaping and then there is this grungy, grody, ugly roof. It’s like detailing a beautiful car and leaving the wheels covered with grease and road tar.

It all started when shingle manufacturers began using fiberglass as the base mat for making shingles. Because it is much thinner than the rag base material once used, they chose to use limestone as a filler to “beef up” the shingles. Guess what one of algae’s favorite foods is? Yep, this cheap and plentiful filler has now become the food source of the ever present algae spores floating through the air.

However, metal poisons the algae and it does not grow when a metallic substance is introduced to the fiberglass shingle roof. Just like the picture shows, the metal antenna stand has killed the algae below it and the roof is clean. The best way to get rid of algae is to let mother nature and copper strips installed at the top of your roof do the work over time. Some will tell you to use a diluted bleach mixture to clean the roof, but that can harm landscaping and damage the shingles. Don’t even use power washer and shingles in the same sentence. That can make a bad situation worse as your shingles go flying across the neighborhood from the power washer blast!

While is Down for Maintenance…

Maintenance is an essential part of any good roofing system…and website. If you need to contact us due to the bad weather today, we’re still here to help.


In the meantime, I thought this would be a great opportunity for you to view my blog and read a few articles. Because this is a blog and not a website, I go into more detail on subject matters such as ‘do it yourself’ checks on your roof.

There are many pictures on the site and if you click on the blogroll or websites, you’ll have plenty to view.

As you know, our new metal roofing division is well under way. Here is a vaulted barrel roof we just finished. What a great way to add beauty and value to your home. As soon as we make some improvements on our website you will be able to see many more examples of the creative work of our sheet metal “artists”.
