FAQs

How often should I have my roof cleaned?

We recommend having your roof professionally cleaned every 1 to 3 years, depending on the local environment, the type of roofing material, and the presence of moss, algae, or debris. In the Pacific Northwest, where damp conditions encourage moss growth, annual maintenance is often ideal. Regular cleaning helps preserve the integrity of your roof, prevents costly repairs, and maintains your home’s appearance. Skipping cleanings can lead to moisture buildup, mold, and premature aging of roofing materials.

Is soft washing safe for my home’s exterior?

Yes—soft washing is a gentle yet highly effective cleaning method specifically designed for delicate surfaces like siding, stucco, painted wood, and roofing materials. Unlike pressure washing, soft washing uses low pressure combined with eco-friendly cleaning agents to remove dirt, algae, mildew, and stains without the risk of damaging surfaces. It's not only safe but ideal for preserving the finish and longevity of your exterior materials while achieving a thorough, deep clean.

What’s the difference between moss removal and liquid moss treatment?

Moss removal is the physical process of clearing moss from surfaces, typically by brushing or gentle scraping combined with rinsing. This is perfect for thick or established growth. Liquid moss treatment, on the other hand, is a preventative and curative solution that kills moss spores at the root level and helps prevent future regrowth. At Surface Renewal LLC, we often recommend using both together—removal followed by treatment—for the most effective and long-lasting results.

How does professional gutter cleaning protect my home?

Clogged gutters can lead to a variety of problems, from roof leaks and water damage to foundation issues and landscape erosion. Our gutter cleaning service ensures that rainwater flows away from your home properly, reducing the risk of overflow, basement flooding, mold growth, and even pest infestations. We also check for signs of wear or damage and remove all debris, so your gutter system works efficiently year-round, especially during heavy rains or storms.

Why should I seal coat my asphalt driveway or parking lot?

Seal coating creates a protective barrier over your asphalt surface, defending it against UV rays, rain, oil spills, and general wear and tear. Over time, exposure to the elements can cause asphalt to dry out, crack, and break apart. Seal coating not only restores its dark, polished look but also extends its lifespan by preventing moisture penetration and chemical erosion. For businesses, it also boosts curb appeal and enhances safety for vehicles and pedestrians.
