What does commercial roofing in Riverside cover?

Commercial roofs are different from house roofs. Most are flat or nearly flat, cover a large area, and carry equipment such as air conditioning units, vents and drains. Water has fewer places to run, so every seam and penetration matters.

Our commercial roofing work includes:

  • Leak repairs and seam repairs.
  • Roof coatings that extend the life of an aging roof.
  • Section replacements and full re-roofs.
  • Drain, scupper and flashing repairs.
  • Roof inspections for owners, landlords and buyers.

Typical buildings include small retail units, offices, warehouses, restaurants and multi-unit apartment buildings.

Which commercial roof systems are common in Riverside?

Single-ply membranes (TPO and PVC)

White or light-colored sheets with heat-welded seams. They reflect heat, which suits the Inland Empire climate.

Built-up and modified bitumen

Layers of felt and asphalt, or rolled sheets, common on older buildings. They can be repaired and coated.

Spray foam and coatings

Used to add a reflective, waterproof surface over a sound roof, or to seal an aging one.

Metal roofing

Used on many warehouses and light industrial buildings.

The right choice depends on your building, the roof deck, your budget and how long you plan to own the property. California's energy code includes cool roof requirements for many commercial re-roofs, which is why reflective surfaces are common. Your contractor should explain which rules apply to your roof.

Repair, recoat or replace: which is right for my commercial roof?

  • Repair suits isolated leaks on a roof that is otherwise sound.
  • Recoat suits a roof with a sound deck and dry insulation but a worn surface. It needs a moisture check first.
  • Replace suits a roof with wet insulation, widespread failure or leaks that keep returning.

We check for trapped water before recommending a coating, since coating over wet insulation wastes money. For a house-sized job, see roof repair in Riverside. If you want a written, documented opinion first, start with a roof inspection in Riverside.

Commercial pricing depends on the details of the building. Common factors are:

  • Roof area and the system you choose.
  • The condition of the deck and insulation.
  • Access, including hoisting equipment and staging areas.
  • Rooftop equipment that must be worked around or raised.
  • Drains, edge metal and flashing that need replacement.
  • Permit and code requirements, including cool roof rules.

Timing ranges from a day for a leak repair to several weeks for a full re-roof on a large building. Work can be done in phases so the building stays open. Weather pauses the job, because a roof cannot be left open to rain.

What should I expect on the day, and when should I call?

Before work starts, expect a plan for roof access, safety, noise and the areas of the parking lot or yard that will be used for materials. Tenants should be told in advance. When the work is done, the crew clears debris and sweeps the area for nails and fasteners.

Call when you see stains on ceiling tiles, standing water on the roof after rain, bubbling or open seams, or when you are buying or leasing a building and want to know the roof condition. A leak above inventory or equipment is worth a call right away.

Ask any roofer for proof of license and insurance, including workers' compensation coverage for the crew. See all of our work on the Riverside roofing home page.

Questions about roofing in Riverside

How long does a commercial roof last?

It depends on the system, the quality of the install and how well the roof is maintained. Many single-ply and modified bitumen roofs last roughly a couple of decades with care. Regular inspections, clean drains and quick repairs of small leaks make a big difference in how long a commercial roof lasts.

Can my business stay open during a re-roof?

Usually, yes. Most re-roofs are done from the top, and work can be phased in sections. There will be noise, and some areas around the building may be blocked off for safety and materials. Tell us your business hours and busy times so the work can be planned around them.

What is ponding water and does it matter?

Ponding is water that stays on a flat roof more than a day or so after rain. It adds weight and speeds up wear on the roof surface, and it often points to drain problems or low spots in the deck. A roof inspection can show whether it needs a drain fix, extra drains or a new slope.

Can a flat roof be coated instead of replaced?

Sometimes. Coatings work when the deck is sound, the insulation is dry and the existing roof is stable. Coating over wet insulation or a failed roof wastes money. We check for trapped moisture first and explain if a coating, a repair or a replacement fits your roof.

Does a commercial re-roof need a permit?

Commercial re-roofing generally needs a building permit, and some projects have energy code or structural requirements as well. Confirm the rules with the City of Riverside building department. A roofer who works in the area should be able to explain the steps and tell you who applies for the permit.

Do you work with property managers and landlords?

Yes. We work with owners, property managers and tenants, and we can give a written scope, photos of problem areas and a quote that you can share with the building owner or your insurer. Tell us who needs to approve the work so the schedule and paperwork fit your process.
