Your West Covina Roofing Stormwater Checklist Before Rain

Where These Checklist Items Come From

Each group below comes from a West Covina, Los Angeles County or National Weather Service record.

The City publishes stormwater requirements for construction sites, and this checklist keeps only the roofing items. It covers roofing materials and debris, and leaves other construction activities to those documents.

The City also publishes an LID screening checklist, which sorts stormwater planning by project category. LID means low impact development. Not every roof replacement needs an LID plan, so ask the City about your project.

Keep Materials On Site and Covered

Bundles, rolls and fuel belong on your own property, contained and covered when not in use.

The City hosts a small-construction BMP flyer for work sites like yours. BMP means best management practices, and several of the flyer's practices apply directly to roof work. The flyer says building materials and fuel must be contained and covered on site.

1. Confirm bundles and rolls sit on your property, not on the street.
2. Confirm every stack is covered when work stops or rain moves in.
3. Confirm fuel cans and loose building materials stay contained and covered.
4. Check who applies for a right-of-way permit before anything sits on the street.
5. Walk the property at the end of the day and note any uncovered stack.

Cover the Debris Bin and Sweep Around It

Tear-off debris belongs in a covered bin, and someone sweeps the ground around it daily.

Tear-off means removing the old roof covering, and that debris carries grit, nails and paper. The City's flyer says to always cover dumpsters with a rollback tarp. The word always matters here, so ask who keeps that cover over your bin.

The City's General NPDES Notes set stormwater requirements for construction sites in West Covina. They require sites to contain wastes and pollutants during an unanticipated storm. They also require one controlled temporary disposal area, kept separate from stormwater runoff.

1. Confirm the bin always has its rollback tarp cover in place.
2. Check that the ground around the bin is swept at the end of each day.
3. Agree on one controlled temporary disposal area, away from runoff and the storm drain.
4. Confirm perimeter controls surround the bin and any portable toilet.
5. Check who holds the right-of-way permit if the bin sits on the street.

Protect the Storm Drain at Your Curb

Ask who keeps protection around the nearest storm drain for the whole job.

Untreated runoff from a work site can reach creeks, rivers and the ocean. The City's flyer says storm drains must be protected at all times. Gravel bags and straw wattles are the low barriers the flyer names.

Never place anything in a public storm drain yourself. Ask the crew or the City who installs and maintains these controls.

1. Confirm gravel bags or straw wattles protect the storm drain nearest your curb.
2. Confirm perimeter controls surround the work area as well.
3. Keep your own vehicles off the controls, because tires can damage them.
4. Ask who removes caught sediment before the next rain.
5. Check that absorbent material or a wet/dry vacuum stays on site for spills.

Keep the Hauling and Disposal Records

Save the records that show where your old roof material went.

West Covina's current waste-diversion forms point to Athens Services or a City-approved self-haul path. They also request disposal records and flag permits for bins placed on the street.

Which path applies depends on your particular project, so start with the City's current form. Published forms change over time, so an older copy may not match today's requirements.

1. Read the City's current waste-diversion form before anyone orders a bin.
2. Ask whether Athens Services or an approved self-haul path fits your project.
3. Ask for disposal records and keep them in your project file.

Check the Forecast Before the Roof Opens

Look up the local forecast and current hazards before anyone opens up the roof.

The National Weather Service office in Los Angeles posts local forecasts, radar and current hazards. Search your own location on that site instead of trusting an old printout. A forecast is general guidance, not a promise about conditions at your address.

1. Check the local forecast and current hazards the day before work starts.
2. Look at the radar again on the morning the crew opens the roof.
3. Recheck the forecast before late-day work continues on an open roof.
4. Ask your roofing team what weather stops work for the day.
5. Ask whether covers stay on site, since the City's notes address an unanticipated storm.

Check the Roof and Gutters Before Winter

Los Angeles County tells residents to check roofs for leaks and clear rain gutters before winter.

West Covina sits in Los Angeles County, California, and that County winter guidance is a useful starting point. Keep your own share of the work at ground level, and leave ladders and roof access to the crew.

A small roof repair before the season starts can save you a wet ceiling later.

• Look for stains or drips on your ceilings before the rain starts.
• Ask your roofing team to clear leaves and grit from gutters and downspouts.
• Watch where water spills when the downspout runs.
• Note any loose flashing or slipped shingles you can see from the ground.
