Mr Patch Roofing and Maintenence | Roofing Services in Daly City, CA 94014

Signs of roof deck rot in our area include spongy spots you can feel when walking on the roof, sagging sections, or interior water stains. The persistent fog and moisture here can trap under shingles. Mr Patch conducts a thorough inspection to assess the damage. We then carefully remove the affected shingles, replace any rotted decking with new, treated plywood, and ensure proper sealing and ventilation to prevent future moisture issues, restoring your roof's strength.

Sun-damaged shingles are very common in Daly City due to intense UV exposure. We start with a detailed evaluation. Often, isolated damaged shingles can be carefully replaced to match your existing roof, which is a cost-effective repair. However, if the damage is widespread and the shingles are near the end of their lifespan, we'll provide an honest assessment and discuss replacement options that offer better sun resistance and longevity for our local climate.

We recommend bi-annual maintenance, especially in spring and fall. Our service includes clearing debris from valleys and gutters that hold moisture, checking for loose or damaged shingles from wind and sun, inspecting flashings around chimneys and vents, and ensuring attic ventilation is adequate. This proactive approach helps prevent moisture buildup that leads to rot and catches small issues with shingles before they become major leaks, saving you money in the long run.
