We safely cleaned the asphalt shingles of these Office Condos using our non-pressure soft wash system. Kleen Roofs takes care of both residential and commercial roofs. Since Wyoming is a suburb on Grand Rapids it is in our service area which covers all of Western MI. Black Streaks had started to take over on these roofs, making the building look bad, and starting to ruin the shingles. Not only do we remove the black streaks, but we keep them from returning for years. Call Kleen Roofs Today if you own a commercial building that has a dirty roof. We can safely clean it, and return the great look of the building.
