Roof Repair in Denver: Can Cleaning Make A Roof Last Longer?


January 3, 2018

Roof repair in Denver can be pricey, depending on the job. To avoid this expense, many homeowners make an effort to take good care of their roof so it lasts for as long as possible. There are a number of ways to keep a roof in good shape so you can protect it from damage. One way is to get the roof cleaned by a professional on a regular basis. Here’s what you need to know about roof cleaning and how it affects the lifespan of shingles:

Cleaning Removes Black Spots

Black spots will start to develop on shingles over time. Many homeowners believe this is a sign that the roof is nearing the end of its life, but that’s not always the case. These black spots are actually a type of algae that is spread by airborne spores. Shingles become trapped underneath this algae, stuck in a moist and warm environment until the roof has been cleaned. If it’s not cleaned right away, the moisture and heat trapped underneath the algae could damage the shingles or shorten their lifespan.

Pressure Washing Can Damage Roofing Material

Regular cleanings will typically extend the life of shingles, but it’s important to note that high pressure washing is not an appropriate way to clean a roof. High pressure washing can actually damage the asphalt shingles or significantly shorten their lifespan. Before hiring a roofing company, be sure to ask whether or not high pressure washing will be used when the roof is cleaned. If it will be, find a different roofer that is more knowledgeable about caring for shingled roofs.

The Proper Cleaning Method

The Roof Cleaning Institute of America and the Asphalt Roofing Manufacturers Association recommends using a “soft wash” method of roof cleaning. Soft washing involves using low pressure nozzles attached to a pressure washing machine.  A biodegradable chemical that removes algae, mold, and mildew will be applied to the roof using these special nozzles.

Since the roofer will be using a low pressure machine, there’s no need to worry about shingle damage. There’s also no reason to be concerned about how the chemicals used in a soft wash will affect landscaping. None of the chemicals used in a soft wash will hurt your plants, so you don’t need to protect landscaping prior to a roof cleaning. Learn which surfaces are safe to clean with a pressure washer.

Removing this algae will ensure that the shingles do not deteriorate due to moisture and heat. With regular roof cleanings, homeowners can keep their shingles looking their best while also extending their life span!
