Ice dams are formed when heat from the inside of a home escapes into the attic and warms the roof decking during the winter. This heat, combined with heat from the sun, can melt snow on the roof. Melting snow on the upper roof and in the valleys then runs down toward the eaves as water. When it reaches the cold eaves and gutters it refreezes. The continual thaw and re-freeze process creates ice dams. The result is water backing up under the roof shingles or behind fascia board where it can soak through the roof decking or wall sheathing, causing damage to attics, ceilings and walls.

There is no benefit to hand-nailing shingles. None of the leading shingle manufacturers recommend hand-nailing. Some roofing companies promote this technique, but the technique itself is not what is important to a quality installation. What counts are the skills and training of the installer. Our factory-certified installers use pneumatic nailers which are often more efficient and consistent than hand nailing.

We highly recommend the removal of the old roofing material before installing new asphalt shingles. The removal allows a professional to inspect the condition of the existing wood deck and all related roofing components to find any defects so that they can be fixed. Once all repairs are done, new shingles can be installed evenly and effectively. If the old shingles are not the same size and shape and are not laying flat without buckles or curls, the new roof will likely look much like the old roof and experience premature leaks due to further cracking or buckling.

Over the lifetime of the roof, the excess granules that are not fully embedded into the shingles during the manufacturing process, will wash away. Normally this is not cause for concern unless large areas of exposed asphalt start to appear, in which case immediate attention is required.

No. Inside the building there is no difference between asphalt shingles, wood roofs and metal roofs. This is because most metal roofs float over the roofing deck, providing an air space that deadens sound waves. Also, modern building codes make buildings more resistant to noise than in the past. On the outside of the home, some metal roofs are slightly noisier.
