Most jobs run smooth: crews show up on time, work cleanly, and finish when promised. Staff like Chris, Aaron, Mike and Myles handle customers with care and explain work clearly without pushy sales tactics. Estimating sometimes lapses, and one reviewer felt a separate protection fee should have been listed upfront. Named installers and managers (Chris, Aaron, Mike, Myles, John, Ramon) earn repeated praise for professionalism and attention to detail. Shingle, skylight, flashing, and roof replacement work stands out. Pricing sits mid-range compared to bigger competitors. Long-term customers report roofs holding up well years later.

The owner personally manages projects, answers calls directly, and follows up after completion with photos or site checks. Work quality is remarked upon for detail and durability: one customer returned after three years with an unrelated concern and Randy resolved it immediately at no charge. Multiple reviewers note the crew leaves sites cleaner than they found them and sticks to promised timelines even in extreme heat. Materials are carefully matched for color.

Multiple repeat clients return years later, trusting them with second roofs. The business has repaired roofs damaged by competitors and earned consistent praise for cleanup so thorough yards are left cleaner than before arrival.

Andrew typically quotes same-day and has crews mobilized within 24 hours, with thorough cleanup a consistent plus.

One older complaint about months-long delays and radio silence may no longer reflect current operations. The 4-person crew moves quickly (full reshingles in 2 days), explains options clearly, and often patches damage free before major work begins.

Reviewers highlight composite deck expertise, roof repairs, and full-scope additions. Sam and the crew keep job sites tidy and work through design changes flexibly. Yet the 18% one-star rating suggests inconsistency: some jobs don't meet stated skill levels, and a few clients report disconnects between promises and delivery.
