<h3>From roof repairs to installation, roofing professionals handle a wide variety of services.</h3>
Here is a list of <a href="https://www.diamondcertified.org/industry-overview-roofing-101/" target="_self">common roofing services</a> requested of contractors by homeowners:
Metal Roofing Installation <a href="https://www.diamondcertified.org/guide/the-typical-cost-of-a-metal-roof/" target="_self">Metal roofing</a> is a popular choice for its durability, flexibility, and number of colors and styles. Once known as tin roofs, metal roofing is available as copper roofing, aluminum roofing, steel roofing, stainless steel roofing, corrugated roofing, standing seam metal roofing, metal shingle roofs and metal panel roofs. Metal roofing is weather-resistant, lightweight and portable. It’s often used on residential buildings, commercial buildings and industrial buildings.
Steel Roof Installation Steel roofs are a good choice for harsh climates and as a design element for modern homes. Most steel roofs are installed as rolled roofing, standing seam roofs or metal shingles. Some steel shingles mimic the appearance of slate shingles, wood shingles and tile shingles.
Roof Panel Installation Whether made of corrugated metal or translucent fiberglass, roof panels are good choice for homes, greenhouses and patio covers. Metal roof paneling comes in a variety of colors and styles. Roof panel installation is often quick and attractive, and the lightweight panels are a good choice for commercial or residential roofing.
Roof Repairs Common roof repairs are required to fix improperly installed gutters, roof leaks, missing shingles, roof flashing leaks, skylight flashing, roof valley flashing, roof ridge vent damage, gutter problems and nail holes. Most roofing contractors provide emergency roof repairs and roof maintenance.
Roof Shingle Installation Roof shingles, including those made by Owens Corning, CertainTeed, IKO, Tamco, Celotex and GAF-ELK, are made of individual, overlapping roof shingles. Most are laid in rows with the top shingles overlapping the lower shingles. Roofing shingles are typically made of asphalt, but they can also be metal shingles, stone shingles, tile shingles or wood shingles. Roof shingles come in a variety of colors and styles.
Flat Roofing Repair &amp; Installation Unlike sloping roofs, flat roofs are horizontal or nearly horizontal to the building. They may be residential or commercial roofs, and they’re often made of tar and gravel, rubber roofing, membrane roofing or metal roofing. Many buildings incorporate flat roofing so they can support HVAC systems, living roofs/Green roofs and living areas on the roof surface.
New Roof Installations New roof installations on new homes and existing structures are a complete replacement of existing roof structures. New roofs are recommended for existing homes that have leaky roofs that regular roof repairs won’t fix. New roofs are installed by roofing contractors and may include tile roofs, rubber roofs, shingle roofs, wood shingle roofs, and metal roofs.
Roof Replacement Roof replacements are the removal and reroofing of an existing building. <a href="https://www.diamondcertified.org/really-need-new-roof/" target="_self">Roof replacement is an alternative to roof recovering</a>, and is often called reroofing. Reroofing can change the shape or style of an existing roof, and it may incorporate new roofing systems or roofing materials to update and add value to a home or building.
Rubber Roof Repair &amp; Installation Rubber roofing, often installed in rolled roofing form or liquid rubber roofing, is a specialized roofing cover for roof repairs or new roofing. Rubber roofs may be a good choice for roofs that leak or for flat roofs. Rubber roofs are often installed on commercial and industrial buildings, but they’re available as rubber roof shingles and recycled rubber roof tiles for residential homes.
Roofing Tile Installation Clay tiles, solar roof tiles, slate roof tiles, concrete roof tiles, plastic tiles, cedar tiles and ceramic tiles are all popular <a href="https://www.diamondcertified.org/video-tile-roof-maintenance-expert-tip/" target="_self">roofing tile</a> choices. They are long-wearing, unique and often sustainable roofing options. Roofing tiles are available in many styles, including flat tiles, imbrex and tegula tiles, Roman tiles, mission or barrel tiles, interlocking roof tiles, and interlocking pantiles.

Do you have a lot of questions about your upcoming roofing project or roofing in general? You’re not alone. Below, we answer several commonly asked questions about roofing repair and replacement, as well as hiring and working with a professional roofer.&nbsp;
<h3>Q: How do I know if I need a new roof or roof repairs?</h3>
A: Quality roofing contractors will inspect your roof and help you <a href="https://www.diamondcertified.org/really-need-new-roof/" target="_self">decide whether repair or replacement is the best solution</a>. Smaller areas of damage and minor leaks may be fixed with simple roof repairs. Extensive missing or damaged shingles, rotting roof boards, high energy bills, water stains on interior ceilings and walls or large roof leaks may indicate that a roof replacement is needed.
<h3>Q: What roofing materials can I choose from?</h3>
A: There are several types of roofing materials that are popular among local homeowners, including: Asphalt shingles are a common choice for new roofs. They’re reasonably priced, they range from simple three-tab shingles to durable architectural shingles, they come in many colors and types, and they’re easy to repair. Asphalt shingles have a shorter lifespan (about 15 to 30 years) and aren’t as environmentally-friendly as some other roofing material choices.
Wood shingles and wood shake roofing are usually made from cedar wood. They often blend in with a natural environment, weather to an attractive gray color, and are easy to repair and replace. Wood shingle roofing can last 30 to 50 years if it’s maintained properly. However, wood shingle and shake roofing can be expensive ton install and <a href="https://www.diamondcertified.org/diamond-certified-experts-how-to-maintain-your-roof/" target="_self">requires more maintenance</a> than other types of roofing.
Tile roofing is a popular choice for new roofs because it’s durable and attractive. Roof tiles can be made from concrete or clay and come in several colors and styles. Tile roofing is easy to maintain, fireproof and very durable. Tile roofing can be expensive and heavy, and it’s generally a better choice for new homes because of the structural requirements due to the weight of the material. Tile roofing can also be fragile and repairs can be complicated.
Metal roofing, including copper roofs, steel roofing, aluminum roofing and tin roofs, is becoming a common choice. While it can be expensive to install, metal roofing is very durable and will outlast other roofing materials. It’s lightweight, it comes in many colors and it has a long lifespan—at least 50 years in most cases.
Slate roofing is a beautiful and unique choice. It’s fireproof and low maintenance, and it lasts years longer than other roofing materials. However, slate roofing can be expensive because it requires specialized installation and more maintenance than other types of roofing.
<h3>Q: How do I know which type of roof is the best choice for my home?</h3>
A: Each home is different, just like the needs of the homeowners. Your roofing company can help you choose the best roofing material and roof style for your home, budget, and unique wishes.&nbsp;
<h3>Q: How long will it take to reroof my house?</h3>
A: Roof replacement can take a few days to several weeks, depending on the size of the home and the roofing materials used. Weather and the skill and experience of the roofing contractors can also have an impact on the speed of the reroofing process.
<h3>Q: Should I choose tear-off reroofing or a roof-over roof construction?</h3>
A: Some roofing contractors will install a new roof on top of your existing roof, which is known as a roof-over or roof overlay. This can save some money on the roofing project since there are no costs for roof removal. However, other roofing companies recommend removing the old roof before installing the new roofing material, which is known as tear-off reroofing, for a better quality roofing job. Talk to your local roofer about your specific reroofing needs.
<h3>Q: Are there eco-friendly roofing materials and methods I can choose from?</h3>
A: Yes. A new roof with good insulation can make your home more energy efficient and keep it more comfortable. There are also several ways to make your roof installation more eco-friendly. First, find out if your roofing contractor can recycle old roofing materials. Some roofing contractors dispose of old roofing shingles and materials in a more environmentally-sensitive way. It’s also possible to choose eco-friendly roofing materials for your new roof. From Green roofs (roofs that are partially or completely covered with vegetation) and environmentally-friendly composite shake roof shingles to recycled shingles and metal roofing, there are many environmentally-friendly roofing options your roofer can offer.
<h3>Q: What happens if someone gets hurt while working on my roof?</h3>
A: When you hire legitimate roofing contractors with the correct license, liability coverage and workers’ compensation insurance, you won’t have to worry. Workers’ compensation insurance covers every employee of the company in the case of accident or injury. You will not be held responsible for damages. Make sure you ask your roofing contractor to show you a copy of their active workers’ compensation policy.
