Answer:

5. If a shingled roof is discolored does it need replacing?

NO. Concerning asphalt shingles, when looking at the condition, the color, or discolor, has very little to do with the shape the shingles are in. The discoloration you are seeing may be tree sap, tree spores, or other organic materials, which have embedded themselves in the shingle, trapped moisture, and have rotted and mildewed, therefore causing the discoloration you see on many homes. This in no way destroys the integrity or affects the performance of the shingle.

Many new, high-end shingles have been treated with an anti-mildew agent that slows the mildews growth, but the product is still too new to see if it prevents it completely for the life of the shingle.

If you are selling your home or would just like your home to be more attractive there are pressure washing companies that can clean this discoloration from the roof of your home. I recommend the new "low-pressure" or "fog" systems that may take off less of the asphalt material on your shingles.

I have been told by roofing experts, the best way to tell the condition of shingles is by looking at the lower corners of the tabs. If this portion is curled it means that the roof may need to be replaced soon. Generally, the worse shape the shingle is in, the more curled they will be. This is a part from the obvious, such as shingles falling off, hanging by one nail, splitting, etc.
