How do I know whether my roof needs repair or replacement?
Isolated damage may be repairable, while widespread deterioration, repeated leaks or problems beneath the shingles can point toward replacement. Age is useful context, not a diagnosis. Have the roof condition and repair feasibility assessed before choosing the scope.
What affects the cost of an asphalt roof replacement?
Roof area, pitch, access, number of existing layers, shingle selection and flashing details affect the price. Damaged roof decking can add work once the old roofing is removed. Compare written estimates that identify the same materials and explain how concealed damage will be priced.
Are impact-resistant shingles worth considering in Minnesota?
Impact resistance is worth comparing where hail is a concern, but a laboratory rating does not make a roof hail-proof. Compare the exact product rating, appearance, installed price and written warranty exclusions. Ask your insurer directly whether your selected product qualifies for any policy discount.
What should be included in a roof replacement estimate?
Look for removal and disposal, the named shingle and roof-system components, underlayment, flashing, ventilation work and property protection. The proposal should also explain cleanup, concealed decking repairs and the separate material and installation warranty terms.
Can new shingles be installed over the old roof?
That depends on the existing layers, roof condition and applicable installation requirements. A tear-off allows the roof deck and concealed details to be inspected before new roofing is installed. Compare the complete scope rather than treating an overlay and a tear-off as equivalent bids.
How long does roof replacement take?
Roof size, complexity, weather and any concealed damage affect the installation schedule. Ask for a project-specific estimate that distinguishes material lead time from days of work at your home, including how weather delays and unexpected repairs will be handled.
How long does an asphalt shingle roof last?
There is no single lifespan that applies to every shingle roof. Product selection, installation, ventilation, weather exposure and maintenance affect its useful life. A warranty term is not a prediction of replacement age; assess the roof condition rather than relying on age alone.
