Frequently Asked Questions

I have heard that pressure washing can damage my roof. What is your process to make sure that it doesn’t?

Tile Roofs

Tile roofs are inspected at the time of estimate. Tile roofs can be cleaned with air alone or with gentle pressure washing. Most times tile has moss, which creates pressure in the tiles, allowing the tile edges and corners to crack and split. Debris is not good on tile, as it causes moss growth and can cause leaking. All valleys will be cleaned out to ensure proper drainage of water running off the roof surface. Most tile roofs require tile taping on joint seams routinely every three to five years. Yearly maintenance for debris removal.

Renewal Tile Treatment

Renew is a two-in-one complete chemical. Renew seals concrete, protecting it from moisture, which leads to cracking and pitting of the concrete tile. Renew can also be sprayed as a Moss Treatment. Retarding the growth of moss is what Renew does best. Renew can be sprayed on clean or dirty tile to remove or prevent the growth of moss, as well as cleaning the roof surface behind itself in between rain cycles.

Will your process leave a mess?

Roof cleaning is typically a messy process. We provide total clean-up from top to bottom. By cleaning and treating in two separate appointments, the house is rinsed twice to ensure no spots are left or missed. We double check all work to ensure top quality. Depending on the amount of roof run off, a fine dirt comes off the roof. The more black pore mold, fungus and debris, the more there is to clean. We rake and rinse the mess up. Our motto is “We Never Leave A Mess.”

What if I need repairs?

Repairs can be assessed at time of roof inspection. After the roof is cleaned, we can tell you the exact shape it is in. We can replace and repair any roof. GotMoss has over 15 years of roofing experience and is a licensed, bonded, and insured roofing contractor. GotMoss backs up all work with a five-year roof certification. If the roof is beyond repair and cannot be certified, it will be passed up for re-roofing. This is why we inspect all roofs for key signs at the time of the initial proposal. Inspection includes: ridge-cap, shake condition, venting, flashing, and valleys.

How often should I clean my roof?

With proper maintenance, such as keeping your roof free of debris, you should expect to repeat this process every three to five years. Routine gutter cleaning is recommended at least once a year.
Debris adds heat and causes rot and decay as well as moss. Routine rinsing of your roof and watching for any loose or missing shakes will extend the life of your roof. Be aware that wind storms around the Puget Sound are notorious for blowing various materials off, so periodically walk around and visually inspect your roof for these items.
We offer maintenance programs for moss and debris control for all types of roofs, decks, fences, and concrete surfaces.

Do I need to be at home?

No, your duty as a homeowner is to make sure all windows and doors are closed completely. All vehicles should be moved away from the house and out of the driveway, as we have hoses running around the house and don’t want to damage your vehicles. Please be sure to advise us of any cars, boats, campers, or anything that you do not want to get wet. We walk the perimeter of the house and look for planter boxes, furniture, tools and move them away, as this helps to make the clean-up process more efficient. The more items out of the way, the easier clean-up will be.

We strongly recommend that you schedule any other projects, such as window washing or house painting, after the roof is cleaned and treated
