4 Things You Should Know About Algae On Asphalt Shingles


Are you tired of the unsightly asphalt shingles on your roof that are damaged from algae spores? Depending on the extent of algae damage, you might need to get the entire roof replaced. However, it is also possible that repairing and pressure washing the roof will be sufficient. This article has a list of information that you might find helpful in regards to your asphalt shingle roof.

1. Why Algae Spores Destroy Asphalt Shingles

Algae spores are detrimental to asphalt shingles because they consume limestone. Asphalt shingles are made mostly of limestone, so they can develop holes when algae consume it. Those holes will get larger until the problem is fixed. Waiting too long for to get damaged shingles repaired can cause the roof deck to deteriorate from exposure to outside elements.

2. The Price to Get Asphalt Shingles Repaired

You must keep in mind that a repair will only be possible if the roof deck is not in too bad of shape. For instance, if algae have deteriorated the asphalt shingles to the point of the roof deck developing holes, you might need to get the entire roof replaced. If only the shingles have suffered damage, you can get them replaced. Repairing a 10x10 foot area of asphalt shingles is estimated at a minimum of $100.

3. What Pressure Washing Might Cost

You can rent pressure washing equipment and clean algae spores on your own for as little as $40 per day. However, it is ideal to leave pressure washing your shingles to a professional because the powerful water can cause damage if handled incorrectly. Professional pressure washing is estimated to cost a minimum of $0.08 per square foot. The slope of your roof will also affect the overall price, as a steeper roof can make the task more complex for the contractor.

4. Ideal Replacement Roofing Materials

If you end up needing a new roof and don't want to use asphalt shingles again, you can opt for metal. The great thing about a metal roof is that it can mimic shingles, only without the risk of getting damaged from algae spores. A rubber roof is another option that you can consider, as it is a great material when it comes to resisting damage from rainwater exposure. Get in touch with a contractor to find out if algae spores have damaged your asphalt shingles beyond repair and to discuss alternative roofing materials.
