A roof shows distress through visible signs that point to trouble below the surface. MDS Roof Doctors technicians start by noting the symptom, then trace the path of water or wind to the actual failure under the shingles or panels. Each service addresses one common pattern of damage so the fix matches the problem exactly.
Homeowners can first clear gutters of debris and note any interior ceiling marks after heavy rain. These observations help our crews decide whether the issue stays at the surface or requires lifting shingles to reach the underlayment. The services below cover the full range of roof conditions found on American homes. Every service below is available from MDS Roof Doctors across the USA.
Water stains on ceilings usually trace back to a break in the underlayment or a nail that has backed out. Our technicians lift the surrounding shingles, replace the damaged felt, and reseal the penetration so moisture stops migrating into the attic space.
Missing or curled shingles expose the felt to sunlight and wind-driven rain. Technicians remove the affected course, install new shingles with proper offset, and check the nails on adjacent rows to prevent further uplift along the same slope.
Dents or loose fasteners allow water to enter at the seams. Crews tighten or replace the screws with neoprene washers, apply compatible sealant along the ridge, and check for corrosion that has spread from the original puncture.
Hail leaves fractures in the granule surface while wind lifts tabs at the edges. Technicians walk the slope, mark every impact point, and replace the compromised shingles rather than patching so the roof regains uniform wind resistance.
Rusted step flashing or separated counter flashing lets water run behind the wall. Technicians remove the old metal, install new pieces with correct overlap, and integrate them with fresh underlayment to direct water back onto the roof plane.
Annual checks reveal soft spots in the decking or clogged valleys before leaks appear inside. Technicians probe suspect areas from the attic, photograph granule loss on the surface, and note any ridge vent damage that affects overall ventilation.
Sagging sections or separated joints cause overflow that soaks the fascia and soffit. Crews realign hangers, replace rusted elbows, and verify that downspouts discharge water at least five feet from the foundation.
When multiple layers have failed or the deck shows widespread rot, replacement becomes necessary. Technicians strip to the rafters, install new underlayment and ice-and-water shield at the eaves, then apply fresh shingles or panels with updated ventilation.
Start with the most obvious sign. Interior water marks after rain point first to leak repair. Missing or curled shingles along one slope call for shingle repair. Dents on metal panels or loose screws indicate metal roof repair is required.
Check the perimeter next. Rusted flashing around chimneys or valleys shows the need for flashing repair. Hail craters or lifted tabs after storms require storm damage repair. Sagging gutters that spill water onto the roof edge need gutter repair. Widespread granule loss and soft decking mean roof replacement is the remaining option.
