Summer humidity in the Twin Cities and across Central Minnesota brings more than muggy air—it brings hidden challenges
In Minnesota, a roof has to perform under weather conditions that push roofing materials and roof construction methods
For many Eagan homeowners, the roof is one of the most expensive parts of the home to repair
If your roof has isolated damage, such as a few missing shingles, a repair may suffice. However, widespread curling, cracking, or granule loss often signals the need for a full replacement. Shingles that appear “bald” or have patches of discoloration indicate aging and vulnerability to leaks. At Twin Cities Siding and Roofing, we assess shingle wear to determine if targeted replacement is an option or if a more extensive solution is needed.
Given the city’s variable weather conditions, we recommend high-quality asphalt shingles from brands like CertainTeed or GAF, which offer enhanced durability and wind resistance. These shingles are designed to withstand high-impact conditions, including hail and strong winds. Additionally, architectural shingles provide better insulation and aesthetic appeal compared to standard three-tab shingles. Our team helps homeowners choose styles and colors that match their home’s design while offering maximum performance.
We use GAF shingles, an innovative roofing product made with NEX® Polymer Modified Asphalt Technology. Its lifespan varies depending on several factors but typically lasts between 20 to 30 years.
Accurate and seamless shingle installation is key to a durable roofing. Twin Cities Siding and Roofing offers expert shingle replacement, and other roofing solutions.
Our team is highly-skilled and works with precision and care. Whether it is a simple shingle replacement or a full roof replacement, we guarantee a work that lasts. Call us today at (651) 571-9557, and receive a free consultation.
