Every roof works as a system of layers, and the shingles or panels on top are only the part you can see. Under them sit underlayment, decking, flashing at every wall, chimney and valley, boots around the pipes and vents along the ridge, and a leak usually starts where one of those pieces fails. Good roof repair in Maplewood starts by tracing the water back to where it gets in, since water runs along rafters and decking before it shows up inside.
Roof trouble in Maplewood tends to come from one of three places: weather, age or a detail that was done wrong when the roof went on. Storms lift and crease shingles, bruise them with hail and drop limbs on the roof. Age shows up as curling, cracking, bald shingles and dried out pipe boots, while bad details show up as leaks at flashing, valleys and skylights no matter how new the roof is.
It helps to know a little about the roof before you talk to a roofing contractor. Write down where the stain or drip is, when it shows up and how old the roof might be. Say what kind of roof it is, whether asphalt shingle, metal, tile, slate, cedar or a flat roof, since the repair depends on the material. You do not need to know the cause, only what you are seeing.
