Summers Are More Fun with a Backyard Deck

When I was growing up, my family home had a backyard deck. I didn't realize how much I loved it until I later moved into my own home that didn't have one. We used to have family over for outdoor gatherings and cook out on it. It was covered, so if it rained, it never ruined the party! As a teenager, one of my favorite ways to relax was to go outside onto the deck and listen to the rain fall on its roof. The sound was so soothing. After enduring one summer in my new home with no deck, I was determined to have one installed quickly. I found a local contractor who got the job done quickly and accurately, and my house now feels like a "home!" I decided to start a blog to share what I learned during the deck construction process along with some other tips!

About The Harm Of Algae & Moisture To Asphalt Shingles

Has your roof become horrible to look at because the asphalt shingles have black stains and are curled up? You are likely dealing with an algae and moisture problem that should be repaired before the inside of your house is damaged. Find out below about the harm algae spores and moisture can cause to asphalt shingles, as well as what a roofer can do to fix the problem.

What Makes Algae & Moisture Bad for Asphalt Shingles?

Algae spores are bad for asphalt shingles because it leads to a roof that is unappealing due to the black streaks that they leave. However, the most harmful thing about algae spores is that they are able to deteriorate the asphalt shingles. The spores basically consume the limestone that is in the shingles, which can leave holes in them. Algae spores are able to survive by having access to moisture.

When there is too much moisture on asphalt shingles, your roof can quickly deteriorate. The curled up shingles from moisture causes the roof deck to be exposed to rain water and the ultraviolet rays of the sun. Your roof deck can end up with water damage that leads to mold. The mold can get inside of your house if you don't invest in a prompt roof repair.

How Should a Roof with Algae & Moisture Damage Be Repaired?

A roofer will have to remove all of the damaged shingles that are curled up. He or she will also remove shingles with damage from algae spores consuming the limestone. Your roof will then have to be pressure washed to get rid of the black streaks from algae.

The next step will be to get rid of the moisture problem. If there are trees near your roof, they may be blocking the shingles from getting sunlight. A lack of sunlight can be a problem when it rains because it takes longer for the water to evaporate off of the roof, which is why the trees must be trimmed. The roofer will also make sure that your house is equipped with functional rain gutters that are not clogged or leaning. Rain gutters can overflow and create moisture problems when they are full of debris.

Don't allow algae and moisture problems to destroy your asphalt shingles and cause you to spend money on a new roof. Speak to a roofer like one from Fredericksburg Builders so he or she can make the necessary repairs as soon as possible!
