A residential roof consists of various materials that are important for the roof's longevity. For instance, there is usually an underlayment material placed on top of the deck of the roof before materials such as shingles or tiles are attached. The underlayment provides an extra layer of protection for the deck and can deter the deterioration process throughout the years. Failing to get any of the materials on your roof repaired quickly when problems arise can lead to severe damage that will likely require new roof construction. If you need more information about the problems and concerns that you should be aware of about your roof, continue reading this article.
Unappealing Dark Streaks on the Roof
You might be wondering what the dark streaks are on your roof, and you should know that they are likely due to algae spreading. Algae can be detrimental to shingles, so it is important to make sure the algae is removed as soon as possible. Don't try to remove the algae with a pressure washing machine, as it can release water that is powerful enough to cause damage to your roof. For example, the powerful water can cause shingles to loosen up or move out of place. It is actually wiser to hire a professional to remove the algae so it can be done in the most cautious and thorough way possible.
Installing New Shingles Over the Old Ones
There is a roofing technique that can be used to repair a roof on a low budget, which is called re-roofing. Basically, you can save money because the old materials that are on your roof will not be removed before the new materials are installed. The roofers will have less labor and the job will get done a lot faster. However, it isn't in your best interest to invest in re-roofing to save money, as the old materials can cause untimely wear to the new materials. For example, if there is water trapped beneath the old shingles, it can make the new ones deteriorate faster than they should.
Keeping Moisture Exposure Under Control
After your roof is repaired, try to do what you can to prevent untimely damage. You can start by keeping moisture in control, by regularly getting the rain gutters cleaned. If leaves or debris crowd the gutters, rainwater can get trapped and create a moist environment on the roof. Moisture can also lead to mold growth, mildew, and soften up the wooden deck.
