How can I tell if my roof needs a repair or replacement?

The common factor is the age of your roof. If it’s less than ten years old, you may not need to replace it yet. Unless of course, you have storm damage. Excessive wear on signs like shingles and flashing may also indicate that you should get a replacement instead of repairing an older installation with more leaks in its seams and dips underlayment caused by shrinkage over time from weather exposure.
