Asphalt shingles are the most common residential roofing material in America — and Dons Roofing Repair has repaired thousands of shingle roofs throughout Lake Mathews, CA. From missing shingles to complex system failures, we fix it right.
Asphalt shingle repair seems straightforward — lift and replace a damaged shingle, seal a flashing joint, apply roof cement to a crack. But shingle repairs done poorly create more problems than they solve. Improperly nailed shingles blow off in wind. Mismatched materials create visible patches that stand out and accelerate differential aging. Roof cement applied as a cure-all creates a brittle, cracking mess that fails within a few seasons.
Dons Roofing Repair approaches shingle repairs with the same rigor as a full replacement. We assess the full scope of damage before recommending any repair, match replacement materials as closely as possible to the existing installation, and complete work that performs and weathers properly for years after we leave.
Shingle repair is the right answer when damage is isolated to a specific area, the surrounding roofing materials are in good condition with several years of remaining life, and the cost of repair is substantially lower than replacement. We always provide an honest assessment — if the roof is near end-of-life and the repair cost approaches 30-40% of replacement cost, we'll tell you directly and recommend the more economical path forward.
One of the challenges of shingle repair is matching the existing installation. Shingle products change over time, and an exact match is often impossible after a few years. We work to achieve the closest possible visual and functional match, sourcing materials from the same manufacturer family and color line when available. For larger repair sections, we can sometimes use material salvaged from less-visible roof areas to create better matches on the primary slopes.
No-Cost shingle roof inspection and repair estimate — same day availability, honest assessment.
The original flat-profile asphalt shingle — 20-25 year lifespans. Many 3-tab products are being discontinued, making matching more challenging but not impossible for our experienced team.
The most widely installed shingle today — multi-layer construction with a dimensional profile and 30-40 year warranties. Wide product availability makes matching much more achievable.
Class 4 rated shingles with reinforced construction for hail resistance. Matching requires sourcing from manufacturers of impact-rated products — we stock and work with all major brands.
