Homeowners in Hemet often ask a crucial question before replacing a roof: Will the new system meet local building codes and wind/hail requirements? The short answer: yes—when your project is properly permitted, specified, and installed by a licensed contractor who knows Riverside County and City of Hemet rules.
At Inherited All Seasons Roofing, our Hemet Roofing Experts experts recommend proven materials, compliant installation methods, and thorough documentation so your roof passes inspection and protects your home for the long haul.
Quick Answer (What You Need to Know)
- Codes that apply: City of Hemet amendments to the 2022 California Residential Code (CRC), California Building Code (CBC), ASCE 7-16 wind design maps, and California Title 24 (Energy Code) for reflectivity/ventilation. WUI (Wildland-Urban Interface) rules may also apply depending on your location.
- Wind resistance: Choose shingles or assemblies tested to ASTM D7158 (Class H) or D3161 (Class F), use proper 6-nail patterns, ring-shank nails, edge metal, and secure underlayment. Our Hemet Roofing Experts experts recommend documentation that clearly states the wind rating.
- Hail resistance: While large hail is uncommon in Hemet, UL 2218 Class 3 or Class 4 impact-rated shingles or metal systems add durability and may qualify for insurance discounts.
- Fire rating: California jurisdictions commonly require a Class A roof covering. We specify Class A assemblies for Hemet homes.
- Permits and inspections: Pull a roofing permit, schedule mid-roof and final inspections, and keep manufacturer and code documentation on hand.
What Codes and Rules Apply in Hemet?
Your roof must comply with:
- City of Hemet building department requirements (local amendments and inspection procedures).
- 2022 CRC/CBC for roofing materials, installation, ventilation (CRC R806), flashing, and roof decks.
- ASCE 7-16 wind design maps adopted by the CBC; local officials publish the design wind speed and exposure category used for permitting.
- California Title 24, Part 6 (Energy Code): In many Inland climate zones, cool-roof performance (solar reflectance/thermal emittance) can be required or provide compliance credit for reroofs. Our Hemet Roofing Experts experts recommend verifying the exact requirement at the start of the project.
- Wildland-Urban Interface (WUI) and Class A: Many areas require Class A roofing for fire resistance. We standardize Class A assemblies unless the jurisdiction states otherwise.
- HOA/CC&R rules when applicable.
Inherited All Seasons Roofing coordinates with the City of Hemet to confirm the latest local amendments before we finalize your scope and submit for a permit.
Wind Design: How We Build for High Gusts and Santa Ana Events
While Hemet is inland, roofs still see gusty Santa Ana winds and seasonal storms. Performance comes from the whole system—not just the shingle.Our Hemet Roofing Experts experts recommend:
- Shingle wind ratings: Use products tested to ASTM D7158 (aim for Class H) or ASTM D3161 (Class F). Many premium shingles provide enhanced sealing technology and can qualify for higher wind warranties when installed with 6 nails per shingle and specified accessories.
- Nailing and fasteners: 6-nail patterns as required by manufacturer and code for higher wind zones; ring-shank, hot-dipped galvanized nails for superior pull-through resistance.
- Deck and sheathing: Verify sheathing thickness and nailing schedule. Replace damaged OSB/plywood and use correct edge/field spacing. In higher wind exposures, tighter nailing schedules may be required by the inspector.
- Starter, hip/ridge, and edge metal: Factory starter strips at eaves/rakes, properly overlapped hip/ridge caps, and ANSI/SMACNA-compliant drip edge at eaves and rakes for uplift resistance and water management.
- Underlayment: High-traction synthetic underlayment installed with cap nails per manufacturer; self-adhered membranes at vulnerable areas (valleys, transitions, low-slope tie-ins). Proper lapping and fastening is critical for wind.
- Flashing and penetrations: Step and counter-flashing at walls, new pipe boots, sealed fasteners, and cricket/saddle details behind wide chimneys.
- Attic ventilation: Balanced intake/exhaust per CRC R806—helps shingle life, reduces heat buildup, and supports Title 24 compliance. We calculate net free ventilation area and specify baffles where needed.
Documentation matters. Our package includes product data sheets, ICC-ES reports or UL listings, and manufacturer instructions to demonstrate compliance during inspection.
Hail Resistance: Smart Upgrades Even If It’s Rare
Big hail isn’t frequent in Hemet, but choosing resilient products is still a wise investment.Our Hemet Roofing Experts experts recommend:
- UL 2218 impact-rated shingles (Class 3 or Class 4) for the best protection against occasional hail and wind-blown debris. Class 4 is the top tier.
- Stone-coated steel or standing seam metal systems with documented impact ratings where aesthetics and budget align.
- High-density underlayments that cushion impacts and improve secondary water shedding.
- Insurance-friendly documentation that lists UL 2218 ratings—useful when discussing potential premium credits with your carrier.
Note: Some tile products are robust, but many aren’t UL 2218-rated. If you prefer tile, we’ll discuss attachment methods, underlayment upgrades, and impact expectations in detail.
Title 24 and Cool Roof Options for Hemet Homes
California’s Energy Code can require or credit cool-roof materials—especially in hotter inland zones like Hemet. Our approach:
- Verify your specific climate zone and whether steep-slope cool-roof values are prescriptive for your project type (new build vs. alteration).
- Offer shingle lines with cool-roof granules (cool colors), reflectivity/thermal emissivity documentation, and CRRC listings.
- Balance energy performance with HOA aesthetics and budget.
Our Hemet Roofing Experts experts recommend cool-rated shingles that meet both the energy targets and the wind/impact specs above, so you don’t have to compromise durability for efficiency.

- Permit-ready scope: A clean submittal with product cut sheets, wind/impact ratings, and a clear installation plan reduces delays.
- Crew execution: Trained installers follow manufacturer instructions to the letter—nail patterns, fastener type, flashing details, and ventilation ratios are verified on site.
- Quality control and inspections: We schedule required inspections (sheathing/mid-roof if applicable, and final). A lead foreman walks the job with a checklist before every inspection.
- Closeout documentation: You receive warranty registrations, product data sheets, and photo logs. This packet is helpful for resale and insurance.
