Leak repairs in Saint Leonard start at $350 for a simple fix. We find the source with a water test or thermal scan, repair the damage, and warranty the work. If the repair costs more than 30% of a replacement, we'll tell you.

Wind damage doesn't always look obvious from the ground. Lifted shingles, broken seals, exposed nail heads. You can't see any of that without getting on the roof. Our Saint Leonard inspector does a full 27-point inspection, free of charge.

New roof installation on new construction means getting the ventilation right from the start. We calculate intake and exhaust requirements based on attic square footage and install the right combination of soffit vents and ridge vent. Saves you money on cooling bills in Maryland.

Our Saint Leonard crews install Timberline in the full system configuration to qualify for Golden Pledge warranty. ASTM D3462 and D7158 Class H certified.

Flat roof leaks usually happen at penetrations, seams, or flashing details. We locate the source, repair it properly, and coat the surrounding area. If the membrane is shot, we'll recommend replacement. Not a band-aid.

TPO is our most-requested commercial membrane in Maryland. Reflective, energy-efficient, and it welds together at the seams for a watertight bond. We install 60-mil and 80-mil systems with 15-20 year manufacturer warranties.

Improperly sized gutters cause fascia board rot and foundation erosion. We calculate gutter capacity using the rainfall intensity formula: roof square footage x pitch factor x rainfall rate (inches/hr for Saint Leonard). Standard 5" K-style handles 5,520 sq ft of effective roof area. Bigger roofs or steeper pitches need 6" gutters with 3x4" downspouts. We hang with hidden hangers screwed into rafter tails every 24".

Infrared moisture scanning available for Saint Leonard commercial and flat roof inspections. Thermal imaging locates trapped moisture in the insulation layer without cutting core samples. We use Flir E8 cameras to map wet areas, then core sample only the suspect zones to confirm. Saves time, reduces disruption, and gives you a precise repair scope instead of a guess.

Emergency tarping is the first priority. We cover the exposed area to stop water entry, then schedule the permanent repair once conditions allow. We don't charge extra for emergency tarp jobs. It's part of the repair cost.

A skylight installed wrong will leak. The flashing has to integrate with the shingle courses. Step flashing on the sides, headwall flashing on top, and a sill pan underneath. We use manufacturer flashing kits because they're engineered to work with the skylight frame.
