Why Mercer Roofing Is Sheridan’s Preferred Roof Repair Company
Sheridan homeowners call us because we understand what these roofs actually are. Not a single one of them is a cookie-cutter suburban roof. Most are pre-1970s farmhouses with original board sheathing, barns with corrugated metal that has been patched for decades, and outbuildings that have two or three layers of roofing stacked on top of each other. Our Roof Repair team has torn off more skip sheathing in this part of Placer County than we can count.
Grant Whitlock leads our crew, and he has made the Threshold Standard the backbone of how we operate. Every technician is background-checked, identity-verified, and arrives in a clean uniform with a photo ID badge. The name and photo are sent to your phone before we pull up. That is non-negotiable. For homeowners who are often alone, or have young kids, or simply do not want a stranger at the door without proof of who they are, this is the differentiator that matters most.
Founded in 2000 and part of the Threshold Group family of home-service companies, Mercer Roofing is independently owned and operated. We dispatch crews to Sheridan daily across the Highway 65 corridor, and because we specialize in the older rural stock here, we carry the right materials in our trucks: plywood decking, ice and water shield, drip edge, and ridge venting suited to valley-floor heat.
Flat Roof Repair in Sheridan
Flat roof repair in Sheridan is a different animal than what suburban crews in Lincoln or Rocklin deal with. Here, flat roofs are usually on equipment sheds, porches, carports, and the occasional mid-century addition, and most are built with rolled roofing or modified bitumen that has been baked by 105°F-plus summers and then pounded by atmospheric river rain. The combination is brutal. The underlayment gets brittle, seams lift, and water finds the nail holes. A typical Sheridan flat roof patch runs $475 – $950 depending on the square footage and how deep the decking damage goes.
When Sheridan flat roofs fail
The pattern we see over and over again is a roof that looks tired but holds through summer. Then the first real winter storm hits, and a ceiling stain appears. Standing water sits on the low slope, seeps through a separated seam, and saturates the insulation board underneath. By the time you see it inside, the decking is already soft.
What a proper flat roof patch includes
We do not just spread sealant over the problem. We cut out the damaged section, inspect the decking below for rot, replace it if needed, apply a new membrane patch with proper bonding, and seal all edges. If the decking is too far gone, you need a full section replacement, which is where the written price matters. You approve every dollar before we cut anything.
Shingle Roof Repair in Sheridan
Shingle roof repair in Sheridan often exposes more than the damaged shingle. Because so many farmhouses on acreage have had layer stacked on layer over original skip sheathing, a three-shingle patch can become a small tear-off in the field. Loose granules, curling edges, and cracked shingles from valley-floor heat are the visible problems. The hidden one is the rusted drip edge or the failed underlayment underneath. Expect to pay $425 – $1,200 for a typical shingle repair here, and up to $1,850 if the decking underneath needs replacement.
Why patch repairs fail in Sheridan
Skip sheathing with three layers of old asphalt shingles does not seal at the nail holes. Water gets in through the same holes again. We have pulled off patches that were only weeks old and found the original leak still running. That is why we inspect first, then give you a written price that reflects what we actually found.
What we install instead
When we replace shingles on Sheridan homes, we use GAF, CertainTeed, or Owens Corning architectural shingles with a proper starter strip and ridge vent when the structure can support it. Most of these old farmhouses have zero ridge venting, and heat exhaustion is what cracks the shingles in the first place. We include ice and water shield in valleys and drip edge on every replacement because the winter storms here demand it.
Trusted Brands We Service in Sheridan
We install and repair shingles from GAF, CertainTeed, and Owens Corning, and we keep stock on our trucks for the most common Sheridan scenarios: architectural shingle bundles, repair-grade flashing, ice and water shield, box vents, and rolled roofing for flat sections. Because our crews are dispatched specifically to this part of Placer County, we are not running back to a distant supply yard mid-job. The materials show up with us, and the repair happens in one visit. You will know the brand going on your roof, and it will be named on the written estimate.
Common Roof Repair Problems We See in Sheridan Homes
- Multiple shingle layers hiding UV-cracked shingles. Three layers over skip sheathing is common on pre-1970s farmhouses, and a shingle that looks fine in August cracks and leaks after the first January storm. Patch repairs over this fail fast because the nail holes never seal.
- Rusted corrugated metal ridge caps on barns and outbuildings. The caps pull away from the original board sheathing over years of thermal expansion, and water gets in around the ventilation cupolas. Standard residential flashing kits don’t fit; these need custom-cut metal and proper sealants.
- Missing ridge and soffit venting causing heat-cooked shingles. Attic heat in a Sheridan summer regularly exceeds 130°F without proper venting, and asphalt shingles crack and curl from the underside. Adding ventilation is part of repair, not an upsell.
- Failed drip edge letting water behind the fascia. Early farmhouses often have no drip edge at all, and the water runs down the fascia board, rot follows, and the body of the roof slowly separates from the walls. Once the fascia goes, the repair scope expands quickly.

FAQs About Roof Repair in Sheridan
Because 105°F-plus summer heat cracks the asphalt shingles and dries out the underlayment, but the cracks are small and the roof is dry through fall. The first atmospheric river of winter pushes water through those dried-out seams and nail holes, and suddenly there is a ceiling stain. The leak did not start in winter; it started the previous August when the shingle cracked. Call (743) 200-8347 for a free inspection and we will find the cracked shingles before the next storm.
Yes, and we do it regularly. The rusted ridge caps and the penetrations around cupolas need custom-cut metal flashing, not a standard residential kit. We remove the rusted panels, inspect the original board sheathing underneath, replace rotted sections, and install new metal with proper gasketed fasteners and sealants. Written price first, every time.
In Placer County, when a repair crosses a threshold of square footage or involves structural decking replacement, the building department may require compliance with current code, which for old layered roofs usually means a full tear-off down to the decking. We find out before work starts whether your repair will trigger that, and we write the allowance into the contract. No surprise tear-off, no change order you did not approve.
A square is 100 square feet of roof area. Most Sheridan farmhouses run 18 – 28 squares, and barns can double that. The quote matters because materials are priced per square, and a repair that requires replacing decking across three squares costs far more than one square. We measure everything during the inspection and give you a line-item written price.
Yes, on every shingle repair where the decking is exposed, and on every valley repair. Ice and water shield seals the nail holes and the critical seams that leak during atmospheric river storms, and drip edge keeps water from running behind the fascia. These are standard on our repair scope in Sheridan because the winter rain demands them. Call (743) 200-8347 for a free estimate on your repair.
Only if we find damage that was not visible before the roof was opened, and only if you approve the change in writing. We do not open a roof and then hand you a surprise invoice. Every allowance is written into the contract before we start, and any change order is priced and signed before we touch that section. Call (743) 200-8347 and we will walk you through exactly how the estimate works.
