Reroofing is a fairly big job so homeowners are often looking for ways to do it faster and more affordably. One option is to install new asphalt shingles over your existing shingles. This is obviously a lot faster because there is no need to rip off all the old shingles. However, this isn’t always a good solution or even feasible. Here are some of the things which need to be considered.
Algae is actually pretty amazing because it is able to live on a variety of surfaces – including the asphalt shingles on your roof. If you see algae growing on your asphalt shingle roof or see black streaks, it is probably because the algae is eating the limestone filler which is typically found in these shingles. Luckily, the algae doesn’t harm the shingles, but it does look unpleasant.
Before you set about cleaning algae from asphalt shingles, you should read any warranty information about your shingles. Many shingle manufacturers will void the warranty if you use certain cleaning methods, such as a pressure washer. There is good reason for this: if you get too close to the shingles with the pressure washer, the high pressure could damage them.
Even if your roof shingles aren’t under warranty anymore, it is probably best to play it safe and not use a pressure washer. Instead, the best method is to get up on your roof with water and scrub brush or garden hose with a sprayer attachment.
What You Need to Clean Algae from Your Roof
To safely clean algae from your roof, you will need the following supplies:
- A cleaning agent
Asphalt shingles are one of the most common roofing materials. They are affordable, fairly simple to install, and come in many different colors and styles. One of the other benefits of choosing asphalt shingles over the other types of roofing common materials is that they have a long lifespan. Most asphalt shingles can last up to 20 years, and there are some which can last 25 to 30 years. The lifespan of asphalt shingles can vary drastically though depending on the climate. In areas like Colorado where the summers are warm and winters are cold, asphalt shingles will be lucky to make it much past their guaranteed lifespan.
No matter what kind of asphalt shingles you have or how well they are taken care of, they will eventually need to be replaced. Since this is a big job, you will not want to do it if it is not completely necessary. Luckily, it is fairly simple to tell when an asphalt shingle roof needs to be replaced.
Look for Curling and Cuffing
As asphalt shingles age, they start to warp. You will be able to notice the edges of the shingles curling upwards or see cuffing in the shingles. This might be visible on just some or all of the shingles.
