The answer to 'shingle replacement or shingle replacement' is that shingle replacement is generally a more comprehensive and permanent solution compared to shingle replacement. Shingle replacement involves fully removing and replacing all the shingles on your roof, while shingle replacement typically only addresses specific damaged or worn shingles.
Shingle replacement provides a number of benefits, including a longer lifespan for your roof, improved weather protection, and a more uniform and aesthetically pleasing appearance. It's often recommended if your roof is older, has widespread damage, or you're looking to update the look of your home. The downside is that it's typically more expensive upfront compared to spot repairs. Shingle replacement, on the other hand, is a more cost-effective option if you only have a few problem areas on your roof.
