If you’re wondering what to know before replacing your roof, understanding the process can make it easier to make better decisions about materials, contractors and the overall scope of the project.
For homeowners in Riverside and throughout the Inland Empire, a new roof is a significant investment. Your roof needs to protect your home from Southern California’s heat, strong sun, seasonal rain and wind while also complementing the style of your home.
Before you choose a roofing material or sign a contract, here are some important things to know before replacing your roof.
Make Sure You Actually Need a Full Roof Replacement
Not every roofing problem requires a completely new roof.
A localized leak, damaged flashing or a small area of missing shingles may sometimes be repaired. However, widespread deterioration, recurring leaks, damaged roofing materials or problems affecting multiple areas of the roof may make replacement a more practical long-term option.
Signs that it may be time to consider replacing your roof can include:
- Missing, cracked or curling shingles
- Recurring roof leaks
- Water stains on ceilings or walls
- Sagging or visibly damaged areas
- Widespread deterioration
- An aging roof that is nearing the end of its expected service life
The best way to determine whether you need repairs or replacement is to have the roof inspected by an experienced roofing contractor.
Choose a Roofing Material That Makes Sense for Southern California
One of the biggest decisions you’ll make is what roofing material to install.
Tenco Construction Company installs several types of residential roofing systems, including asphalt shingles, tile roofing and flat or low-slope roofing systems. Each option has different advantages depending on the home’s design, roof slope, budget and long-term goals.
Southern California’s climate also matters. Roofing materials here are exposed to strong sunlight, UV radiation, heat and seasonal Santa Ana winds. Current Southern California roofing guides consistently emphasize climate, roof pitch, fire considerations, durability and energy performance when comparing materials.
Rather than simply asking, “What is the best roofing material?”, ask which material makes the most sense for your particular home.
Understand What a Roof Replacement Actually Includes
Homeowners often focus on the visible roofing material, but a roof is a system made up of several components. Knowing what to know before replacing your roof includes understanding what happens beneath the visible shingles or tiles.
A complete roof replacement may involve removing the existing roofing, inspecting the roof deck, replacing damaged materials, installing underlayment, addressing flashing and ventilation, installing the new roofing system and cleaning up the property afterward.
This is one reason two roofing estimates can look very different even when both contractors appear to be quoting the same roof.
When reviewing an estimate, make sure you understand exactly what work is included.
Ask What Happens if Damaged Roof Decking Is Found
One of the most important things to understand before replacing your roof is that the condition of the roof deck may not be completely visible until the existing roofing materials are removed.
The decking provides the structural surface beneath the roofing system. If sections have been damaged by moisture, leaks or deterioration, they may need to be repaired or replaced before the new roof can be installed properly.
Before work begins, ask your contractor:
- How will damaged decking be identified?
- Is any decking replacement included in the estimate?
- How will additional repairs be priced?
- Will you be notified before additional work is performed?
Knowing the process ahead of time can help prevent surprises once the old roof is removed.
Pay Attention to Underlayment, Flashing and Ventilation
The shingles or tiles may be the most visible part of your roof, but some of the most important components are underneath or around them.
- Underlayment provides an additional layer of protection beneath the roofing material.
- Flashing helps direct water away from vulnerable areas such as roof intersections, walls, vents and other penetrations.
- Ventilation helps manage heat and moisture in the attic and roofing system.
These details can have a major impact on the performance and longevity of the finished roof, so they should be part of the conversation when reviewing a roofing proposal.
Compare the Scope of Work, Not Just the Bottom-Line Price
It can be tempting to choose a roofing contractor based on the lowest estimate, but two bids may include very different scopes of work.
One estimate may include tear-off, disposal, new underlayment, flashing work, ventilation improvements and cleanup, while another may not include all of those items.
California’s Contractors State License Board recommends getting multiple written bids and comparing them based on the same plans, specifications and scope of work. (CSLB)
Instead of asking only, “How much does the roof cost?”, also ask:
- What materials are included?
- Is removal of the existing roof included?
- Is disposal included?
- What happens if hidden damage is discovered?
- What type of underlayment will be used?
- Is flashing replacement included where needed?
- How will ventilation be addressed?
- What warranties are included?
A detailed estimate makes it easier to compare contractors fairly.
Understand the Roofing Warranty
Roofing warranties can vary considerably, so don’t assume every warranty provides the same protection.
There may be separate coverage for the roofing materials and for the contractor’s workmanship.
Before signing a contract, ask:
- What does the manufacturer’s warranty cover?
- How long does the coverage last?
- What is covered by the contractor’s workmanship warranty?
- Are there exclusions?
- Is the warranty transferable if you sell the home?
A reputable roofing contractor should be able to explain the warranty clearly before installation begins.
Know What to Expect During the Installation
Roof replacement is a construction project, and homeowners should expect some temporary disruption.
There will typically be noise while the existing roofing is removed and the new system is installed. Materials may be delivered to the property, crews will need access around the home and there may be debris during the tear-off process.
Tenco’s current roofing process includes an initial inspection, detailed estimate, installation and a final inspection and cleanup.
Before installation day, ask your contractor where materials will be placed, how landscaping and property will be protected, how cleanup will be handled and approximately how long the project is expected to take.
Make Sure Your Roofing Contractor Is Properly Licensed
Roofing installation should be handled by a qualified contractor.
California requires contractors performing covered construction work to hold a current license through the Contractors State License Board. Homeowners can verify a contractor’s license directly through CSLB before hiring them. (California Contractors State License Board)
In addition to verifying licensing, ask about:
- Roofing experience
- Insurance
- Workers’ compensation coverage
- Written estimates
- References or reviews
- Installation procedures
- Warranties
- Cleanup procedures
Choosing the contractor carefully is just as important as choosing the roofing material.
Ask About Current California Roofing Requirements
Roofing requirements can change over time, particularly when it comes to building and energy standards.
California’s 2025 Building Energy Efficiency Standards apply to permit applications submitted on or after January 1, 2026. (California Energy Commission)
Requirements can also vary based on the home, project and local jurisdiction.
You shouldn’t have to become an expert in building codes yourself. Your roofing contractor should be familiar with the requirements that apply to your project and be able to explain them.
Think About Your Home, Not Someone Else’s
The roofing system that works best for one home may not be the right choice for another.
A tile roof may complement one home’s architecture, while asphalt shingles may make more sense for another property. Flat and low-slope roofs require roofing systems designed specifically for those conditions.
Homeowners in Riverside and nearby Inland Empire communities such as Moreno Valley, San Bernardino, Temecula, Rancho Cucamonga and Corona should also consider local heat, sun exposure, roof pitch and the design of the home when choosing a roofing system.
The goal isn’t simply to install a new roof. It’s to choose a roofing system that fits your home and is installed correctly.
What to Know Before Replacing Your Roof: Questions to Ask Your Contractor
Knowing what to ask your roofing contractor before work begins can help you understand exactly what you’re getting.
Consider asking:
- Do I need a complete roof replacement or would repairs be sufficient?
- Which roofing material do you recommend for my home, and why?
- What is included in the estimate?
- Will the existing roofing be completely removed?
- What happens if damaged decking is discovered?
- What type of underlayment will be installed?
- How will flashing and ventilation be handled?
- What warranties are included?
- How long is the project expected to take?
- How will my property be protected during installation?
- Who handles cleanup and disposal?
- Are permits or inspections required for my project?
A contractor should be able to answer these questions clearly before you sign an agreement.
