Having milder winters are good and bad if you ask me. Why is it good if you ask; first of all there isn’t a big load of snow sitting on your roof and your furnace is not working day and night to keep your house warm. A roof that is due for a replacement isn’t capable of shrinking in cold temperatures as much as a new roof. Shingles do shrink and expand when there is a change in the temperature. During summer shingles do expand and after ten or fifteen years of expanding and shrinking causes major wear and tear. If you take a closer look at your roof , you can see the lines are starting to appear more and more before the curling begins.
If you ask why the milder winters are bad for your roof; the answer is simple. The shingles are not designed to stay under the direct heat from the sun. Winter is a good time for them to cool of but they have no break from the sun, it will eventually start to curl up and you would need to replace your roof more often.
A year ago just before the weather got warmer we faced a wind storm that damaged a lot of homes in different parts of the town. That is a perfect example for unpredictable weather. The shingles were not ready to expand and bound properly before the wind took them for a ride. For two months straight we were doing repairs in different parts of the town. Majority of the roofs were in rough shape and they should have been replaced previous year but replacing a roof can be expensive and homeowners should be prepared for the necessary repair costs.
It is highly recommended to hire a professional roofing contractor in your area to inspect your roof before and after winter. Age of the roof does not necessarily mean that it will protect you mother nature.
