ROOFING FAQ


Can I install a new roof on top of my old one?

Never, you void the warranty of your new roof and the result is not aesthetically pleasing. If the old roof is not removed you cannot inspect for dry rot and other issues properly. The moisture from the old roof gets trapped and will cause the new roof to age faster.



Why does one side of my roof age faster?

The south side of a roof typically ages faster due to sun exposure. The UV rays will break down the material over time.



Is there a roofing material that prevents moss?

Yes, we provide high-grade shingle material that prevents the growth of algae and moss. Our shingles provide a self-contain time-release.



Is it okay to power wash my roof?

Power washing voids warranty and causes the shingle material to lose its granules which leads your roof less protected from the elements.



How do I know when my shingle roof needs to be replaced?

You will know when your shingle roof needs to be replaced when the shingles are curled or crawled, if the granules are missing and there are bare spots. You will also need to replace your shingle roof if the shingles are broken or missing, buckling shingles and damaged flashings.
