1

Commercial Roofing

What types of commercial roofing systems do you work with?
We install and service TPO, PVC, EPDM, Modified Bitumen, metal, shingle, and tile roofing systems.
How long does a commercial roofing project take?
Small buildings (5,000–10,000 sq ft): usually 1–2 weeks in good conditions. Medium (10,000–50,000 sq ft): often 2–4 weeks depending on complexity. Large (50,000+ sq ft): a month or more, sometimes phased so parts of the building stay usable.
What warranties are available?
Manufacturer warranties of up to 30 years plus our workmanship guarantee.
Will I receive a written report after the inspection?
Yes. You’ll receive a digital inspection report complete with annotated photos, identified issues, and prioritized recommendations for repair or maintenance.
How do I know if I need a full replacement vs. repair?
If leaks are recurring, insulation is saturated, or the membrane is at end-of-life, replacement often lowers total cost of ownership. We inspect and provide a side-by-side repair vs. replace analysis.
What common signs indicate urgent roof problems?
Watch for:
  • Cracked or blistered membrane
  • Ponding water or clogged drains
  • Loose or deteriorated flashing
  • Visible stains or mold inside
Early action on these red flags prevents small issues from becoming business interruptions.
Do you work with HOAs and property managers?
Absolutely. We provide detailed reports, budgeting guidance, and maintenance plans for HOAs, commercial property managers, and facility directors.

Gutter Guards & Rain Gutters

How long do rain gutters last?
Aluminum lasts 20–30 years, steel up to 50, and copper can last 50+ years with proper maintenance.
Do I need gutters if I live in a dry climate?
Yes. Even in dry areas, gutters protect your foundation during occasional storms and prevent water damage.
What are gutter guards and do they really work?
Gutter guards help prevent clogs from leaves and debris. They reduce maintenance but still need occasional cleaning.
Can clogged gutters cause roof or foundation damage?
Yes. Overflowing water can lead to roof leaks, fascia rot, mold growth, and foundation erosion.
What type of rain gutters are best for my home?
It depends on your climate, budget, and style preferences. Common options include aluminum, copper, vinyl, steel, and seamless gutters.
3

Concrete Tile

How long do concrete tiles last?
Concrete tiles typically last 50+ years with proper installation and minimal maintenance. Many tile roofs installed in the 1960s are still performing excellently today.
Are concrete tiles heavy? Will my roof support them?
Modern concrete tiles weigh 2–4 lbs per square foot. We perform a structural assessment during inspection to ensure your roof can safely support the weight.
Do concrete tiles require special maintenance?
Concrete tiles require minimal maintenance — just annual inspections and occasional cleaning. No painting, sealing, or coating required.
What’s the cost difference compared to asphalt shingles?
While the initial cost is higher, concrete tiles provide better long-term value through energy savings, durability, and increased home value. Financing options available.
Can concrete tiles withstand earthquake damage?
Yes. Concrete tiles are engineered to flex and move with seismic activity. Proper installation with seismic clips ensures excellent earthquake resistance.
Do concrete tiles help with energy efficiency?
Absolutely. Concrete tiles provide excellent insulation, reducing cooling costs by 10–15% in summer and heating costs in winter. The thermal mass helps regulate temperature.
4

Synthetic Slate Roofing

What is synthetic slate roofing made from?
Synthetic slate is typically made from recycled rubber, plastic polymers, or engineered composites designed to mimic the appearance of natural slate while being lighter and more impact-resistant.
How long does synthetic slate roofing last?
Most synthetic slate products are rated to last 40 to 50 years or more. Many come with 50-year or even lifetime warranties, depending on the brand and installer.
Is synthetic slate more affordable than real slate?
Yes. Synthetic slate is significantly more affordable than real slate in terms of material, labor, and structural support costs. It offers the same high-end look without the weight or price tag.
Does synthetic slate require roof reinforcement?
In most cases, no. Because synthetic slate is much lighter than natural slate, it doesn’t require additional structural reinforcement — making it ideal for retrofits and modern homes.
How does synthetic slate perform in extreme weather?
Synthetic slate is engineered for durability. It’s resistant to hail, wind, UV rays, and temperature extremes. Many products are Class 4 impact-rated and Class A fire-rated.
Is synthetic slate roofing eco-friendly?
Yes. Many brands use recycled materials in their production, and their longevity reduces landfill waste. The lighter weight also reduces transportation emissions.
5

Clay Tile

Are clay tiles energy efficient?
Absolutely. Clay tiles provide excellent thermal mass and insulation, helping maintain comfortable indoor temperatures and reducing energy costs.
Can I walk on clay tile roofs?
Walking on clay tiles is not recommended as they can break. Our professionals use specialized equipment and techniques for safe roof access during maintenance.
6

Metal Roofing

Is metal roofing suitable for California’s climate?
Absolutely. Today’s best metal roof and insulation combinations reflect the ultraviolet spectrum, keeping a home cooler in hot, sunny areas. Metal is resistant to moisture — preventing mold and mildew in coastal regions — and has fire-resistant qualities.
How much attic insulation is needed for a metal roof?
Your climate zone dictates the levels of attic insulation needed. The US Department of Energy offers a map that shows what to expect in your area.
How much does a metal roof cost in California?
Every property is different — it depends on the material, style, and size of the roof. Ballpark figures: standing-seam metal roofs may cost $10–$15 per sq ft; metal shingles or tiles $7–$12 per sq ft; corrugated metal panels $5–$8 per sq ft.
Are metal roofs noisy when it rains?
No. Modern metal roof insulation comes with solid sheathing, which significantly reduces noise. In fact, they can be quieter than traditional roofs.
Do metal roofs require maintenance?
Regular inspections and cleaning to remove debris are usually sufficient to keep them in excellent condition.
7

Flat Roofing

How long does a flat roof last?
It depends on the material. Built-up and modified bitumen roofs typically last about 15–20 years, EPDM around 20–25 years, and TPO or PVC membranes about 20–30 years with proper installation and maintenance.
What is the best flat roofing material for my property?
It depends on your budget, building use, and climate. TPO and PVC are popular for energy efficiency and heat-welded seams; EPDM is durable and economical; modified bitumen holds up well to foot traffic. We’ll recommend the best fit after an inspection.
Do flat roofs leak more often than pitched roofs?
Flat roofs don’t shed water as quickly, so proper drainage, flashing, and professional installation matter more. A well-installed, well-maintained flat roof performs reliably — most leaks trace back to poor drainage or aging seams.
How much does a flat roof cost to install or replace?
In San Jose, the cost typically ranges from $8.00 to $15.00 per square foot for residential properties. For a standard 1,500-square-foot home, expect to pay between $12,000 and $22,500. Because of San Jose’s climate and California’s strict Title 24 energy codes, costs here are roughly 10–20% higher than the national average.
Are flat roofs energy efficient?
Modern flat roofing materials reflect UV rays, reducing cooling costs and improving energy efficiency.

Skylight Installation & Repair

How long does it take to install a skylight?
Most residential projects are complete in 1–2 days. Commercial projects can take longer, depending on the size and scope. Roof complexity and the type of skylight being installed are also considerations.
Can you install a skylight on my sloped roof?
Skylight installation is possible on most sloped or flat roof structures. During your no-obligation consultation, we assess the feasibility and recommend the best placement options for your preferred design.
9

Emergency Roof Tarping

How long can I keep an emergency tarp on my roof?
Most emergency roof tarps can last between 30 to 90 days when professionally installed, though it depends on the specific conditions at your San Jose property. We encourage owners to schedule permanent repairs as soon as possible.
Does insurance cover the cost of emergency tarping in San Jose?
In most situations, a homeowner’s policy will include coverage for loss-mitigation services like tarping. Deductibles and other factors determine how much you’ll pay — that’s outside our control, but we can provide the necessary documentation for your claim.
Can I install an emergency tarp on my own?
Although it’s possible, many insurance policies require it to be done by a licensed and insured contractor. Working on a damaged roof can be dangerous, but our team is trained and equipped to ensure a safe installation.
