The best in the business at roof leak repair
There are many different causes of roof leaks. When you hire a roofer to fix it, they will be viewing the project through a very narrow lens and may not consider all the intersection points and other mitigating circumstances. So that recommendation to replace your roof could be a very costly unnecessary expense. With expertise in finding and repairing leaks throughout the home and building envelope, our roof leak detection specialists look at all factors that may cause your leak so that our roof leak repair team fixes more than just the surface level issues — we’ll fix your roof leak, for good.

Types of Roof Leaks
Whether you live in a rowhome or free-standing house, in Philadelphia or D.C., we have experience detecting and fixing roof leaks in all kinds of homes. Common roof types include:
Flat Roof Leaks
A flat roof is one of the most common types of roof. Flat roof leaks can develop from a multitude of issues, including old age, penetration and intersection points, a damaged membrane, and more.
Shingled Roof Leaks
Shingled roof leaks have their own unique sets of issues and circumstances such as damaged flashing, clogged gutters, unsealed areas between roof sections, and age.
Fiberglass Roof Leaks
Fiberglass roofs are a popular choice as a walkable roof surface. While they are intended to have a long lifespan and be low maintenance, if they weren’t installed or maintained properly, you may find yourself with a leak.
Roof Deck Leaks
There are a variety of structure types and waterproofing methods for rooftop decks. Roof deck leaks can develop from a multitude of issues including age, weight, deferred maintenance, and connection points to other structures.
Mystery Leaks
Leaks inside your home can sometimes be coming from sources independent of the roof directly above. Potential issues at the property line, connection points to other structures, as well as intersection points of unlike materials, can all mask the source of a leak.

Yes, we fix all kinds of interior and exterior leak issues, whether it's your roof leaking, your ceiling, or anywhere in your home. Our Leak Detection process covers every possible cause in order to find exactly where the leak starts and what it affects. At the end of the process, we repair your ceiling to restore your home to its original condition.
Look for ceiling stains, peeling paint, damp insulation, or water spots in your attic. You may also notice missing shingles, mold growth, or a musty odor after rain.
Most of the time, no. Many roof leaks can be repaired without a full replacement. We determine whether the issue is localized or part of a larger roofing problem before suggesting next steps.
Roof leaks usually stem from aging materials, damaged shingles, cracked flashing, clogged gutters, or poor sealing around vents. Look for these warning signs:
Brown ceiling stains
Peeling interior paint
Damp insulation in your attic
Unexplained water spots
Most roof leaks require isolated repairs rather than a full roof replacement. If a roofer has recommended that you replace your roof, we recommend getting a second opinion from a leak specialist. It could save you countless thousands!
Place a bucket to contain the drip, move furniture and rugs away from the area to prevent water damage, and set up a fan to dry any dampness. Read our guide for more information on emergency leak management and what to expect from your Leak Detection appointment.
We break our process down into distinct phases to ensure accuracy and high-quality results:
Initial Leak Detection: This on-site investigation typically takes between 2 to 8 hours.
Comprehensive Reporting: You receive a detailed Leak Report within approximately 14 business days.
Water Intrusion Repair Phase: Average repairs take 1 to 2 days to complete. Extensive structural work might require a couple of weeks.
Weather Testing: After we complete the repairs, we wait for 3 to 4 weather events to pass. This waiting period proves the leak is fully resolved before we perform cosmetic drywall repairs.
Learn more about our leak detection and repair process.
We'll likely open a viewable area (cutting a hole in the ceiling) on the interior where your leak is presenting. This allows us to explore how the leak is behaving in order to find the root cause of the leak.
We don’t work directly with your homeowner’s insurance, but we will work with you if you are getting reimbursed. If you need extra time to figure out the details with your insurance or are waiting for a check from them, we can adjust or pause with you to make the process as smooth as possible.
We stand by our expertise. If the exact same leak reappears after our repair, we will return to repeat the Leak Detection process free of charge. If we find any issues with our workmanship, we will correct them for free. If we discover completely new, contributing factors, we will provide a clear estimate for those additional repairs.
