If you’re looking for a cost-effective alternative to a traditional chimney, consider having a dummy chimney installed. Dummy chimneys can either be aesthetic-only or fully functional and can be installed on both new and older homes. Whether installed to match your neighborhood’s aesthetic or to vent your chimney, dummy chimneys are made out of a Glass-Reinforced Plastic (GRP) core, then covered with brick or stone slips to look like a traditional chimney.

You cannot replace granules that have been lost off shingles. The granule embedding process is part of shingle manufacturing, and once the bond holding the granules to the shingles has been lost, the granules are gone for good. Shingles with granule loss must be fully replaced to continue offering adequate protection.

You shouldn’t put a new roof underlayment over an old one for a few reasons. Old felt must be removed in order to assess the condition of your roof decking, such as rotting wood or other structural issues. Also, if your roofer doesn't install a fresh layer of felt as is required by shingle manufacturers, your warranty may be voided. Finally, old underlayment removal is often included in the cost of roof repair or replacement, so there's no real benefit to leaving it on before installing a new layer.

Hip roofs tend to cost a bit more than other common styles of roofs. Because of the complex labor needs required to build a hip roof properly, you can expect to spend more on labor if you choose to go with a hip roof over a less complicated roof style.
