The most expensive roofing shingles are typically the most durable. They are premium products, with superior durability and designed for specific conditions (e.g. impact-resistance, fire-resistance), as well as with particular features (e.g. solar shingles)
Many cheap shingles are lower quality, and come with shorter warranties – this is why roofing experts advise you to avoid purchasing the cheapest products you can get. If you are on a budget, you should rather find roofing materials that provide the best quality-price ratio. Asphalt shingles are probably the best example, especially if we think about their popularity.
On the other hand, you should not buy the most expensive shingles just for the sake of buying them, because you will do nothing but throw your money on the window.
In general, you should not purchase shingles for your roof before consulting with a materials specialist from Denver roofing companies. There is a lot of information on the internet about all the roofing materials, but only an expert roofer can recommend you the best solution, after inspecting your building and/ or the existing roof. A professional Interstate roofer has the right experience to suggest the best roofing solutions based on several factors: price, manufacturer’s warranties, the local climate, aesthetics etc.
