What are the Different Types of Roofing Materials for Flat and Sloped Roofs?

Roof life is the most crucial consideration when selecting roofing material because it determines the roof longevity. The roof is a hefty investment; its durability ensures good recovery of the amount invested. Untimely roof replacement is the last thing that homeowners would consider, and only roofing experts like the ones you find at Patriot Roofing & Construction can evaluate whether it is at all necessary. Instead of replacing the roof, there are many ways to restore it, which are more cost-effective solutions and works well. Repairing the roof will ensure that the roof lasts its full life and defers the replacement.

Different Types of Roofing Materials

If you must replace the roof, then instead of sticking to the old roofing material, you can think about using something new that enhances the performance or better suits your budget. It would require gathering information about different types of roofing materials and even understanding the style and architecture of the building that influences the selection. The color and style of the roofing material must match with the overall architecture of the building. Asphalt shingles are the most versatile and affordable roofing material that matches with almost all kinds of architecture and style. However, ranch and cottage style buildings would require a different type of roofing material that goes well with the Mediterranean and European style of buildings. Again, the roofing material for bungalow-style buildings will be quite different from that of buildings constructed in the lines of French style.

Which Roofing Material is Right for You?

Protecting buildings from the vagaries of weather is the primary purpose of roofs that must have an effective system for draining water, and the roofing material contributes to its performance. Built-up roofs made from tar and gravel have excellent water-resisting properties, but newer materials like thermoplastics can also be perfect for flat roofs. Sloped roofs with a pitch or gradient not more than 3 in 12 are suited for using roll roofing, metal sheet roofing tar and gravel roofing. To install shingles or tiles on the roof, the slope must be at least 4 in 12 or higher to ensure the effective draining of rainwater.

You can cover the roof with the material that matches your style and budget and customize it for your needs. The options available when selecting the roofing material for flat roofs will become clear on going through this article.
