Why Choose Our Roof Cleaning Services

We use an appropriate cleaning approach based on the roof surface and its condition, targeting dark streaks, algae, moss, and other buildup that can make a roof look old or neglected. We take care around roofing materials, siding, landscaping, and gutters throughout the process.

Individualized Attention

Just as every customer is unique, so is every project. We treat each client and their project individually, always keeping their priorities in mind. For some that might include curb appeal, while others might prioritize a particular view or the design of a room. Listening is an essential part of how we work.

Ongoing Communication

No one likes to be kept in the dark when their money is on the line. We’ll keep you informed through every step of the process, answer your questions and make sure you and our team share a common understanding of the next steps for any project. Our subcontractors are part of the team — a group of trusted professionals we work with on an ongoing basis.

Accountability and Professionalism

What we start, we finish. Zepp Construction guarantees that we will stick with your project until the last detail is complete. Our attention to detail covers not only every aspect of the job site, including leaving it clean during and after construction, but also the paperwork involved on the business side.

Transparency

We won't pretend every project goes exactly to plan. What we will guarantee is honest pricing before we start, a straight explanation if anything changes along the way, and a team that treats you like a partner, not a bystander, when it does. It's not irresponsible to say we don't know something exactly yet. It's irresponsible to pretend we do.

WHY HOMEOWNERS CHOOSE US

Straight talk, solid builds

Real feedback from homeowners we’ve built for across Washington

We had Zepp Construction out for seasonal roof and gutter maintenance. The roofs (house and pump house) look excellent and I am very appreciative that there wasn't any ground mess left behind. I was fully anticipating needing to blow off at least the asphalt and sidewalks around the house when he was done, but you can't even tell he was here other than the roofs look pristine. And the price was very fair. We will definitely utilize this seasonally for maintaining our roof and gutters.

Great people, Great work, and just all around best contractor in Grays Harbor. Hands down.
Tryly Oliver
Zepp Construction brought specifics to my attention before and during the building process that as a consumer I would have never thought of or realized.
