Elastomeric Roof Coating Restoration on a Multi-Section Low-Slope Residential Roof in Sedona, AZ

Project Overview

A residential property owner in Sedona reached out to us looking for a smarter alternative to a full roof replacement. Their low-slope roof sections were aging and showing the early signs of weathering — worn surfaces, vulnerable flashings, and transition points that needed attention before real problems developed. We recommended a professional elastomeric roof coating system combined with targeted waterproofing repairs, giving the homeowner a cost-effective restoration that extended the life of their existing roof without starting over from scratch.

Problem: Aging Low-Slope Roof Sections with Vulnerable Flashings and Drainage Points

The property’s low-slope roof sections had reached a stage where normal weathering was starting to create real risk. Flashings, drains, scuppers, roof penetrations, and membrane transition points all showed signs of wear — the kinds of details that hold a roofing system together but are also the first places water finds its way in when maintenance gets deferred. The homeowner wanted to get ahead of the problem rather than wait for an active leak to force their hand.

Low-slope roofs in Sedona face a demanding combination of intense UV exposure and monsoon-season moisture that accelerates surface wear over time. Letting that wear go unaddressed on a flat or low-slope system is a reliable path to water intrusion, and the cost of repairing the damage it causes inside the home is almost always far greater than the cost of proactive maintenance. The goal here was clear: restore the surface, reseal the vulnerable points, and protect the investment without a full replacement.

Solution: A Multi-Step Elastomeric Roof Restoration with Reinforced Repairs

We started with a full pressure wash of all roof surfaces to remove dirt, oxidation, and debris and prepare the substrate for proper coating adhesion. From there, we worked through every vulnerable area — inspecting and waterproofing all roof penetrations, vents, and openings, resealing flashings, drains, scuppers, membrane splits, and transition points, and addressing the exterior scupper connections to improve water management off the roof. In areas that needed extra durability, we installed polyester reinforcement fabric before the coating went down.

Once the repairs and prep work were complete, we applied the Polyglass PolyBrite 25 elastomeric roof coating in two coats according to manufacturer specifications. The elastomeric system creates a seamless, flexible membrane that expands and contracts with the roof through temperature cycles — an important quality in northern Arizona where temperatures swing significantly between seasons. We also performed maintenance on the additional low-slope sections of the property that were not receiving the full coating application, followed by complete site cleanup.

Result: Extended Roof Life and Renewed Confidence in Sedona’s Climate

When we finished, the homeowner had a refreshed, seamless roofing surface across the low-slope sections of their property — with every flashing, drain, penetration, and transition point properly sealed and protected. The elastomeric membrane improved the roof’s overall resistance to UV exposure and weather, directly addressing the deterioration that had been building up on the surface and at the vulnerable edges and details.

The practical win here was avoiding a full replacement while still getting a real, lasting improvement in protection. The completed restoration is backed by our 2-year labor warranty, and the homeowner left the project with a roof that was ready to handle Sedona’s climate for years to come.
