R & R Roofing | Roofing Services in Manteca, CA 95336

Proper roof pitch is critical for water drainage in our area. During a new installation, we calculate the ideal pitch for your home to ensure water flows efficiently into the gutters, not over them. We also integrate correctly sized gutter systems and ensure seamless integration at the roof edge (eave) to handle heavy rain and prevent the overflow that can damage your home's fascia, siding, and foundation.

Absolutely. Skylight leaks are often due to failed or improperly installed flashing—the metal seal around the unit. When we perform a roof replacement in Manteca, we remove the old skylight flashing entirely. We then install new, high-quality flashing integrated directly into the new underlayment and shingles, creating a watertight seal. This addresses the root cause, not just a temporary patch, giving you a leak-free skylight.

We take a proactive, local approach. First, we ensure the roof deck has proper slope for drainage. Then, we install a robust ice and water shield in vulnerable areas (like valleys and around penetrations) and use high-quality synthetic underlayment for an extra moisture barrier. Finally, we pay meticulous attention to details like step flashing where the roof meets walls, and we size and pitch your new gutters correctly to manage heavy runoff, preventing the overflow and leaks common in our region.
