Zinc Sulfate Monohydrate 35% Zn - 50 lb Roof Moss Control Powder

Clean Gutters Stay Cleaner When the Roof Stops Feeding Them Moss

A gutter cleaning job can look finished at the downspout and still fail from above. Roof moss breaks loose, slides into the trough, packs around outlets, holds moisture, and brings the customer back to the same clog cycle.

Zinc Sulfate Monohydrate 35% Zn gives professional roof cleaning and gutter cleaning crews a contractor-size treatment option for moss-prone roofs. The 50 lb powder bag supports commercial service routes, property maintenance work, and repeat roof moss treatment programs where smaller retail containers do not make operational sense.

Key Benefits at a Glance

Industrial Moss Control Powder for Roof Cleaning, Gutter Cleaning, and Property Maintenance

Zinc Sulfate Monohydrate 35% Zn is a water-soluble powder supplied in a 50 lb bag for industrial use. The guaranteed analysis is 35.00% zinc and 17.00% sulfur, derived from zinc sulfate monohydrate. The powder format gives contractors flexibility for label-directed moss treatment workflows on compatible roof and exterior surfaces.

For gutter cleaning contractors, the value is simple: moss on the roof can keep sending debris into the gutter system even after the gutters are cleared. Treating moss as part of the maintenance plan helps crews offer a more complete service around the full rain-carrying system: roof surface, gutter trough, outlets, downspouts, and drainage path.

For roof cleaning crews, maintenance teams, and property managers, the 50 lb bag is built for repeat work, multi-property routes, and moss-prone service areas where annual or seasonal maintenance is part of the plan. Use only according to applicable label directions, local rules, surface compatibility, and safety requirements.

GutterAll in Damascus, OR supports cleaning contractors, roof maintenance professionals, property managers, and exterior service crews with moss-control supplies, pickup, local delivery, and nationwide shipping.

The Service Opportunity: Treat the Roof, Not Just the Gutter

Many gutter clogs start above the gutter. Moss holds moisture on the roof surface, breaks apart during rain, and drops organic material directly into the trough. When the outlet gets packed, the customer sees overflow even if the gutter was recently cleaned.

This product helps contractors position moss treatment as part of a stronger maintenance visit. The customer gets more than a cleared gutter; they get a plan for the roof growth that keeps creating the mess.

Best use cases include moss-prone roofs, shaded rooflines, Pacific Northwest maintenance routes, annual gutter cleaning programs, HOA service work, rental property maintenance, and commercial exterior cleaning programs.

Best Uses for Roof and Gutter Cleaning Crews

How Zinc Sulfate Fits a Professional Moss-Control Workflow

Zinc sulfate monohydrate is water soluble. In professional moss-control use, the powder may be applied according to label directions in a manner that allows moisture to carry zinc across the treatment area, or dissolved for a controlled liquid application where appropriate.

Treatment planning should account for roof material, gutter material, slope, drainage path, nearby plants, waterways, storm drains, and weather. Do not use this product where runoff could enter ponds, streams, water supplies, or storm drains connected to waterways.

Do not use on roofs with copper gutters, copper downspouts, or copper flashing. Zinc sulfate can corrode copper. Confirm compatibility before treating any roof system.

Who Uses This Product?

Professional Application Planning Guide

3. Do not use on roofs with copper gutters, copper downspouts, or copper flashing.
4. Put on proper PPE before handling powder, including respiratory protection, eye protection, gloves, and protective clothing.
5. Plan runoff containment so treatment does not enter ponds, streams, storm drains, water supplies, or valued landscape areas.
6. Remove heavy moss or debris first when physical cleaning is required for proper roof and gutter drainage.
7. Apply only by an appropriate method and rate for the surface, equipment, weather, and label directions.
8. Allow treatment time before brushing, rinsing, or removing dead material, based on the site plan and conditions.

Contractor Tip

Sell the maintenance plan, not just the cleaning. Show the customer the roof moss that is feeding the gutters, explain how loose moss reaches outlets and downspouts, and offer roof moss treatment as part of a complete rain-carrying-system maintenance visit.
