Complete Guide to MSR Roll Roofing: 1 Minute to Mastering Your Roofing Options

MSR roll roofing, short for Mineral-Surfaced Roll roofing, is a cost-effective and practical roofing material designed for low-sloped residential and commercial structures. Unlike traditional shingles, MSR roll roofing comes in long, wide rolls, typically 36 feet long by 36 inches wide, making installation much faster and more accessible for DIY enthusiasts and professionals alike. It is constructed from asphalt, fiberglass, and mineral granules, creating a weather-resistant and durable surface commonly used on sheds, garages, porches, and certain low-pitched home roofs where standard shingles may not perform as well.

Types of MSR Roll Roofing:

1. Self-Adhering MSR: Features an adhesive backing for easy installation, minimizing the need for additional adhesives or fasteners.
2. Nail-On MSR: Requires the use of roofing nails for secure attachment, making it suitable for slightly steeper slopes.

Installation Process:

MSR roll roofing installation entails careful surface preparation, precise measuring and cutting, and proper overlapping of rolls to prevent leaks. Start by cleaning the roof deck thoroughly. Lay the roofing roll across the surface, aligning it with the lower edge. For nail-on types, secure with roofing nails along the edges and center. For self-adhering versions, gradually peel away the protective backing as you apply the roll. Each layer should overlap the previous one by at least 2 inches to ensure water tightness. Finish with roofing cement at edges and seams for added protection.

Pros and Cons:

1. Pros: Quick installation, affordable material cost, ideal for low-slope surfaces, easy repairs.
2. Cons: Shorter lifespan (typically 5-10 years), limited aesthetic appeal compared to shingles, not suitable for steep slopes.

From a designer’s perspective, the utilitarian nature of MSR roll roofing is both a strength and limitation. While it serves well for functional buildings, integrating it seamlessly into your overall property aesthetic requires careful consideration. To enhance visual appeal, coordinate the roof’s color with exterior paint, or install trim and architectural details for balance. For those planning sheds or garages as part of their 3D floor planner project, specifying MSR roll roofing can be a budgeting advantage, but always evaluate regional climate and building codes before final selection.

Tips 1:

Always check local building codes before installing MSR roll roofing, as some areas prohibit its use on residential residences due to durability concerns.

FAQ

Q: What is MSR roll roofing made of?

A: MSR roll roofing is composed of asphalt, fiberglass matting, and mineral granules, providing weather resistance for low-sloped surfaces.

Q: How long does MSR roll roofing typically last?

A: The average lifespan is 5-10 years, depending on installation quality, climate, and regular maintenance.

Q: Can MSR roll roofing be installed over existing shingles?

A: It is generally recommended to remove old roofing before installing MSR roll roofing to prevent uneven surfaces and moisture issues.

Q: Is MSR roll roofing suitable for residential roofs?

A: Primarily, MSR roll roofing is used for sheds, garages, and outbuildings. Its use on main residential roofs is often limited due to its shorter lifespan.

Q: What is the minimum slope requirement for MSR roll roofing?

A: MSR roll roofing works best on roofs with slopes from 2:12 to 4:12. Steeper slopes may require alternative materials for proper drainage and longevity.
