Roof Replacement Built to Code, Warranty, and GAF Pro Field Guide Standards

Rockville, MD homes are exposed to driving rain, strong winds, seasonal temperature swings, and aging roofing systems. Many homes in the area have had multiple roof replacements over the years, and improper installation is one of the most common reasons roofs fail early.

Capitol Improvements provides professional roof replacement and roofing services in Rockville, with a focus on proper installation, local code compliance, and long-term performance.

Roof Replacement in Rockville: A Real Project Example

A Rockville homeowner contacted us after recurring leaks during heavy, wind-driven rain. Although the roof had been replaced previously, our inspection revealed major installation failures:

• No ice and water shield at the eaves
• No drip edge installed
• Gutter guards bolted directly into the roofline
• Rotten plywood along the eaves allowing water intrusion

Our Solution

We performed a full tear-off and installed a complete roofing system, including proper underlayments, code-compliant drip edge, decking replacement where needed, and gutter guards that do not penetrate the roof.

Because the roof was installed to manufacturer specifications, the homeowner qualified for a GAF lifetime warranty.

Installed to the GAF Pro Field Guide — Every Roof, Every Time

Capitol Improvements is a GAF Master Elite contractor, and every roof we install follows the GAF Pro Field Guide, which serves as our installation bible.

The Pro Field Guide defines:

• Proper nailing patterns
• Ice and water shield placement
• Underlayment and flashing standards
• Drip edge and edge metal requirements
• Ventilation specifications

Following these standards is required for warranty eligibility and long-term roof performance. We do not deviate from these specifications.

Mid-Century Modern Roof Replacement in Rockville, MD (20854)

This mid-century modern home in Rockville’s 20854 area required a full roof replacement due to improper flashing and rotting T1-11 wood siding. Our team replaced the entire roofing system and installed new step flashing and apron flashing where the roof meets the siding to properly protect the structure and prevent future rot.

Because the home features an exposed rafter entryway, we custom-fabricated metal flashing to maintain the architectural design while ensuring the roof and siding are fully protected. The result is a durable, properly flashed roofing system built to last.

This Rockville home in the 20851 area required replacement of a flat roof over a bump-out addition that was not properly tied into the existing shingled roof. The transition between roofing systems had failed due to improper flashing.
