Roof repair in Potomac.

Potomac's estate roofs are large, steep and broken up by dormers, deep valleys and the occasional turret. Every one of those features is a flashing detail, and on a big footprint there are dozens of them. A failed step flashing at a dormer or a worn valley can leak for months before it shows inside, because water travels along the framing a long way from where it enters.

Materials raise the stakes. Slate, cedar shake and standing-seam metal each need their own repair methods, and patching them with the wrong material or technique causes more problems than it solves. We inspect every slope, including the back planes you can't see from the driveway, document the damage in photos and give you a written quote that spells out the repair for your roof's material.

Potomac is unincorporated, so permits run through Montgomery County rather than a city office. A small repair generally doesn't need one; a larger job that replaces decking or a large share of the roof can, and we check and pull the county permit when it's required. Many Potomac communities have HOAs that regulate roofing materials, profiles and colors, so we match the repair to what's on the house and what the guidelines allow.

Even premium roofs take storm damage. Montgomery County saw damaging winds and tree damage in the June 2012 derecho, hail returns most summers, and heavily wooded lots mean fallen limbs. That damage is often covered by homeowners insurance, and on a large roof we photograph and document every affected slope so your adjuster sees all of it.
