JAF Roofing provides two warranty options: a labor and material warranty, and a material-only warranty. We recommend the labor and material warranty, as it covers complete replacement of faulty materials at no additional cost to you. The material-only warranty, while less comprehensive, covers only the materials and involves minimal costs.

Granules in your gutters can be a cause for concern. These ceramic granules protect asphalt shingles from water and light damage. As shingles erode due to environmental factors, they lose granules. This loss accelerates roof deterioration, potentially compromising your roof's integrity and lifespan.

Curling shingles are indeed a cause for concern. This curling occurs when the oils in the shingles evaporate, causing them to shrink. As a result, the underlying plywood becomes exposed, allowing water to penetrate and potentially damage the wood decking. This can lead to water infiltration in your property, necessitating prompt attention.

We do not recommend installing a new roof over an existing one. While this approach may seem cost-effective initially, it often leads to higher long-term expenses. It can significantly reduce your new roof's lifespan, potentially by half, and increase energy costs. The additional layer impedes proper airflow, causing shingles to overheat and deteriorate faster. This practice may also void warranties in many cases.

Approximately 99% of roof leaks occur at penetration points such as chimneys, vents, flashing, and air conditioning units. These leaks are often the result of installation errors. Proper installation and waterproofing of these areas, which we refer to as flashing detail, is crucial. At JAF Roofing, we dedicate a significant portion of our installation time to ensuring these penetration areas are correctly sealed and waterproofed.
