Project Summary

The Challenge

The homeowners at Creek Court in Cotati were ready for a fresh start. The roofs above units 67 through 77 had given the complex years of faithful service, but time had quietly done what time always does. Decades of sun, rain, and seasonal change had taken their toll, and it was time for something new.

Once our team got to work, the project revealed a story the old roof had been keeping to itself. A significant amount of dry rot was hiding beneath the surface, more than anyone could have known from the outside. Aging homes often carry these kinds of surprises, and this was a moment that called for extra care, not shortcuts.

Our Solution

Rather than rush past the dry rot to stay on the original timeline, we adjusted our schedule to give the repairs the time and attention they deserved. Our team treated and replaced every section of compromised decking before a single new shingle went down. It was the right thing to do for the homeowners, for the buildings, and for the decades of protection ahead.

Once the structure was sound, we installed GAF Timberline HDZ shingles in Weatherwood across the entire complex, paired with new gutters to complete the system. The result is a roof and water management package designed to protect Creek Court for years to come.

Materials Used

This project was completed using GAF Timberline HDZ shingles in Weatherwood, a premium architectural shingle from one of the most trusted names in the roofing industry. The Weatherwood color brings a warm, natural blend of soft browns and grays that complements the wooded Cotati setting and gives the entire complex a refreshed, timeless appearance. As a Class A fire-rated product, GAF Timberline HDZ delivers the kind of long-term performance Sonoma County homeowners deserve, with the dimensional depth and curb appeal of a true architectural shingle.

A complete new gutter system was installed as part of the project, working hand in hand with the new roof to carry water safely away from the buildings. A roof and gutter system installed together is one of the best ways to protect a home from the slow, quiet damage that water can cause over the years.

Beneath the surface, our team also used replacement decking and dry rot repair materials wherever they were needed. The dry rot discovered during the project was significant, and rather than rush past it, we took the time to restore the structural foundation of the roof before installing a single new shingle. The result is a roof system that is truly new from the deck up, built to protect the families at Creek Court for decades to come.

Process

The project unfolded over ten days with a steady, careful rhythm. Our team removed the existing roofing across the full complex, then completed a thorough inspection of the decking beneath. As dry rot was uncovered, those areas were addressed before moving forward, with the schedule adjusted so every repair received the proper time.

With a sound foundation in place, our crew installed the new GAF Timberline HDZ shingles in Weatherwood, working unit by unit to maintain a clean and consistent appearance across all of units 67–77. New gutters were installed as part of the same project, finishing out a complete water-shedding system for the complex.

The job site was kept tidy throughout, and the work was completed with the kind of attention to detail that a multi-unit project deserves.

Results & Benefits

The Creek Court complex now stands with a brand-new roof system built on a foundation that has been carefully restored. The Weatherwood color brings a warm, natural tone that suits the wooded surroundings beautifully, and the architectural depth of GAF Timberline HDZ shingles gives each unit a refined, dimensional look.

More important than the look, the homeowners gained something that matters even more: confidence. Confidence that the hidden problems were found and fixed, not papered over. Confidence that their homes are protected from the elements of time, weather, and everything in between. As homes grow older, their roofs do too, and the families at Creek Court can rest easy knowing Crandall handled the next chapter the right way.

The before-and-after contrast tells the story on its own: an aging, weathered roof gave way to a fresh, dimensional new system built to last.
