Low-Slope Roofing That Handles Sun and Water

Shadowfax Roofing & Solar installs and replaces flat roofing systems including TPO and PVC for homes in Campbell, California.

When your home in Campbell has a flat or low-slope roof, whether on the main structure, an addition, or a covered patio, the roofing material needs to handle standing water, intense sun exposure, and temperature swings without cracking or peeling. Shadowfax Roofing & Solar installs flat roofing systems using TPO and PVC membranes that are built for durability, heat resistance, and long-term water protection.

These materials are applied in large sheets that are heat-welded at the seams to create a watertight surface. TPO is a single-ply thermoplastic membrane known for flexibility and UV resistance, while PVC offers similar performance with added chemical resistance and seam strength. Both materials work well in sunny, weather-variable climates and can support rooftop solar installations when the roof structure is designed to handle additional load.

If your flat roof in Campbell is showing wear or you need a replacement that will last, request a flat roof evaluation with Shadowfax Roofing & Solar.

How Flat Roof Installation Protects Your Home

Installation begins with removing the old roofing material if needed, inspecting the roof deck for damage or soft spots, and ensuring proper drainage so water does not pool. The new membrane is rolled out across the surface in Campbell, trimmed to fit, and seams are welded together using heat tools that fuse the material into a continuous barrier. Flashing is installed around edges, penetrations, and roof-mounted equipment to prevent water entry.

After installation, your flat roof will shed water more effectively, resist cracking from sun exposure, and provide a clean, uniform surface that does not require frequent patching or resealing. You will notice that leaks stop, interior ceilings remain dry, and the roof holds up better during rainstorms. The surface also reflects more heat than darker materials, which can reduce cooling costs during warm months.

Proper installation includes checking for adequate slope or drainage paths, securing all seams and edges, and testing the surface for weak points before the job is finished. The work does not include structural reinforcement unless the deck requires repair, and any rooftop equipment or solar panels are factored into the layout during installation.

What You Should Know About Flat Roofing

Homeowners often ask about material differences, how long flat roofs last, and whether they can support solar panels.

What is the difference between TPO and PVC?
Both are single-ply membranes that perform well in sun and heat. TPO is lighter and more flexible, while PVC offers stronger seam welds and better resistance to oils or chemicals. Either material works well for residential flat roofs in Campbell.
How long does a flat roof last?
TPO and PVC roofs typically last 20 to 30 years depending on installation quality, maintenance, and exposure to extreme weather. Proper drainage and regular inspections help extend lifespan.
Can I install solar panels on a flat roof?
Yes. Flat roofs can support solar panels using weighted or ballasted mounting systems that do not penetrate the membrane. The roof structure must be strong enough to handle the added weight.
What happens if water pools on the roof?
Standing water accelerates wear and can lead to leaks over time. Proper installation includes creating slight drainage paths or installing tapered insulation to move water toward drains or edges.
When should I replace my flat roof?
Replacement makes sense when you see recurring leaks, visible cracks or bubbles in the membrane, or water damage inside the home. Aging roofs that are nearing the end of their expected lifespan should be evaluated before problems worsen.

If your flat roof in Campbell is leaking, aging, or needs replacement before you add solar panels or other equipment, Shadowfax Roofing & Solar can install a durable TPO or PVC system that handles local weather and protects your home for decades. Get in touch to schedule your flat roof evaluation.
