St. Helens Is Our Home, And We Take Care of It

We’re not just another company that serves St. Helens, we live here. We know the neighborhoods, the weather patterns, the Douglas firs dropping needles on your roof every fall, and the moss that takes over every winter. We’re the team your neighbors already trust. Meet our team.

St. Helens homes face a relentless cycle of moisture, shade, and organic growth. Left untreated, moss and algae shorten your roof’s lifespan, clogged gutters cause costly water damage, and dirty siding drags down your home’s value. Our soft wash roof cleaning, professional gutter cleaning, and full exterior washing services stop the damage before it starts.

Whether you’re on Columbia Boulevard, near the courthouse, out by McNulty, or up in the hills, we know your area, we know your roof, and we’ll take care of it right.

Reviews from homeowners in St. Helens

Great Price

They did a great job cleaning the moss from my roof and 4yrs worth of debris from my gutters. Communication was great! In fact, he contacted me and asked if he could even come an hour early, which was welcomed. Super friendly and quick. He finished the whole job in less than 90 minutes. I absolutely would recommend them to anyone!

Thank you, NJM Roof and Gutter Cleaning! Camron was quick to get us on the schedule for a gutter clean out. He powered through the job even though it was raining. Can’t beat the price! St Helens, Oregon, full of hidden gems!

Efficient Work

From the estimate to the execution, everything was excellent. Received estimate and the next week work was scheduled. I received a house washing, window cleaning and gutter cleaning. Very responsive, great communication and fast efficient work. My house was VERY filthy and it looks as close to brand new a 20 y/o house can. Both gentlemen are professional, knowledgeable and personable. Price for all the work was fair and industry standard. I highly recommend NJM and they now have a long term customer!
