Complete roof replacement
One contractor for shingle, tile and low-slope roofs.
The best roof is not chosen from a brochure. We look at roof slope, deck condition, drainage, heat exposure, rooftop equipment, architecture and budget—then walk you through the systems that actually fit your property.

Properties we reroof
Built for homes, multifamily properties and active businesses.
Every property changes the plan. Occupied sites, rooftop equipment, drainage, access, noise, landscaping and daily cleanup are considered before work begins.
Multifamily & HOA
Phased work, resident communication, protected entrances and repeatable specifications across buildings.
Commercial buildings
TPO, PVC, modified bitumen, self-adhered systems and restoration options around equipment and penetrations.
Mixed roof properties
Correct transitions between steep-slope shingles or tile and patios, dead valleys or low-slope additions.
Start with roof pitch
Slope determines which systems belong on the roof.
Final specifications must follow the adopted code, local requirements and the selected manufacturer’s listed installation instructions.
Asphalt shingles
Asphalt shingles are permitted at 2:12 or greater. Roofs from 2:12 to under 4:12 require the code-prescribed special underlayment application. Zenith does not install shingles below 2:12.

Standard clay and concrete tile begin at 2½:12. From 2½:12 to under 4:12, code requires a double-underlayment application; 4:12 and steeper uses the standard prescribed application.
Learn about tile replacementMembrane roof systems
Roofs below steep-slope covering limits need a listed low-slope assembly selected for drainage, deck, use and existing conditions—not shingles or standard tile forced onto the wrong pitch.
Explore low-slope roofingImportant: Below 2½:12, standard clay or concrete tile is not used unless a specifically approved/listed assembly allows it. Existing reroofs and unusual assemblies may require project-specific review.

Heat-welded single-ply roofing often considered where oils, grease or chemical exposure affect system selection.
Learn MoreTorch-Down
APP modified-bitumen systems with robust multi-ply details for compatible low-slope applications.
Learn MoreSelf-Adhered
Multi-ply modified-bitumen roofing installed without open-flame application where the assembly is appropriate.

Real installation conditions
We design around the entire roof—not just the field membrane.
Skylights, drains, walls, HVAC curbs, vents, conduit, edges and transitions determine whether a new roof performs. The proposal should explain how those details are rebuilt and tied into the selected system.
A clear replacement process
From inspection to final documentation.
Inspect & measure
Identify the roof systems, slopes, drainage, penetrations, layers, deck and access conditions.
Compare options
Explain appropriate systems, scope differences, materials, limitations and upgrades.
Prepare & install
Protect the property, remove or prepare existing roofing, address approved deck work and install to specification.
Verify & close out
Complete detail checks, cleanup, photos, maintenance guidance and applicable warranty documentation.
Roof replacement FAQ
Questions property owners ask before choosing a system.
How do I know which roofing system is best?
We start with slope, deck, drainage, existing materials and property use. Then we compare only systems that fit those conditions.
Can shingles be installed below a 2:12 slope?
No. Zenith does not install asphalt shingles below 2:12. Low-slope areas require a compatible listed membrane assembly.
Can tile be installed below 2½:12?
Standard clay and concrete tile are not used below 2½:12 unless a specifically approved/listed assembly permits it. Low pitches need project-specific review.
Do you replace residential and commercial roofs?
Yes. We work on homes, multifamily properties and commercial buildings using steep-slope and low-slope systems appropriate to each structure.
Can you combine systems on one property?
Yes. Many buildings have shingle or tile pitched areas plus low-slope patios, additions or dead valleys. Those transitions must be designed as part of the complete roof.
