WeatherWatch leak barrier is an adhesive roofing underlayment. It is installed at all eaves and valleys. It is important that roofers install this correctly. The severe thunderstorms in Rockville bring driving rains that can blow moisture below the shingles. This prevents the water from contacting the roof sheathing. Ice damming is the primary reason roofers install leak barriers. Every year in Rockville, MD several snowstorms occur. The freeze/thaw process can cause water to be blocked from the gutters below the roofing surface. It can soak the edges of the roof sheathing causing damage over time. The leak barrier seals to the drip edge around the perimeter of the roof protecting the roof sheathing from moisture. No Rockville roof is complete without a properly installed leak barrier.  Ask your roofer how they plan to install a leak barrier so you can be confident your roof is protected.

Pipe collars can be overlooked by most roofers in Bethesda. The standard pipe collars at your local Rockville hardware store will generally only last 7-10 years before leaking or dry rotting. The Ultimate Lifetime Pipe Collars are designed to last 50 years which is the same timeframe as your new roofing warranty. Roof penetrations such as these are often the cause of most leaks, so it is important to use a quality roofing collar. Ask your Rockville roofer about Lifetime Pipe Collars.

FeltBuster Roofing Underlayment is a synthetic underlayment that performs better and is more durable than traditional roofing felt underlayments. The climate in Rockville, MD has extreme heat and severe cold weather depending on the time of year. Those extremes can cause traditional roofing felt to become brittle and damaged over time. Most synthetic underlayments come with a high price tag, but FeltBuster is an affordable option to get the performance of a synthetic roof underlayment without exceeding your roofing budget. Many Rockville roofers use standard felt paper. Be sure to discuss which underlayments are being installed with your roofer. Often the lowest roofing estimates from roofers don't include quality underlayments. 


All Rockville roofers will have different methods of protecting your landscaping.

It's also important that your roofer uses caution around windows and siding. Roofing tar can be difficult to clean from these surfaces. The driveway should also be protected.

GAF roofing requires 9 square inches per linear foot of net free ventilation on eaves and 18 square inches of net free ventilation on ridge locations. Snow Country Exhaust Vent is a common product roofers use in Rockville to achieve this requirement. Many homes in Rockville have soffit vents that provide the correct intake needed. For homes that don't have adequate intake, GAF Cobra IntakePro can be installed in the roofing system. It's important that your ventilation is corrected by your roofer to ensure your roofing warranty is intact. Always ask your roofer how they plan to achieve this.

Not all Rockville homeowners want asphalt or standing seam meatal roofing. Many prefer the look of cedar or slate roofing. Real Cedar and slate roofing aren't commonly used now that high quality syntheic products from EcoStar are available. Not all roofers are experienced with these roofing products, so be sure to ask your roofer if they are comfortable with synthetic roofing products. We recommend the Majestic Niagra Slate andMajestic Niagra Shake product lines from EcoStar. Click the links above to learn more about syntehic roofing in Rockville, MD. Some HOA's actually require these roofing products.

Hiring any contractor can be difficult. Especially when it comes to hiring roofers in Rockville. Always make sure you're hiring a roofer that is licensed and insured. The roofing contractors relationship with the manufacturer is very important if you want to make sure your warranty is intact. A roofer certified by the manufacturer will generally ensure your warranty is active. There are many other things to consider when hiring a roofer. Every homeowner must decide what else is important to them when hiring a roofing contractor. Communication, pricing transparency, clean up, and integrity should also be considered. Online reviews are a great starting point when condsidering a roofer in Rockville. It is also recommended to contact several references. Any reputable contractor should be able to provide a long list of references for you to contact. To most people, their home is their biggest investment. You should feel confident that the roofer you select will act in a professional manner and provide your Rockville home with a quality roofing installation. 


Our company specializes in GAF Roofing Products. This is the main roofing product line we offer. This level of focus has allowed us to become one of the leading GAF roofing installers in Rockville. We are proud to be part of the GAF Roofing Contractor Program. Proper installation is the most important part of any roofing project. We strive to exceed expectations on every roof installation! Selecting the right Rockville roofing product is just as important as the roofer installing it. 


One of the most common issues with roofers in Rockville, MD is they attempt to reuse existing flashing. This is common on chimneys and roof to wall connections. Existing flashing may have damage that can't be seen, so it is important for every roofer to replace all flashing during a new roof installation. Many roofers in Rockville don't install flashing correctly when attaching to masonry. The flashing must be cut into the mortar and sealed to prevent the new roof from leaking. We commonly find roofers install the new flashing without bending it into the mortar and then caulking. Over time this method will fail leaving the Rockville homeowner having to repair their new roof. Be sure to ask your roofer how they plan to address the flashing on your new roof install. ​


Most roofs in Rockville can be completed in 1-2 business days. This should always be discussed with your roofer prior to moving forward with your roofing project. Your roofer should also check the weather prior to removing your existing roof. Larger homes may take 2-3 days. If plywood damage is found it will need to be replaced before the new roofing can be installed. This can also cause some delays if there is significant damage. Overall, roofing is one of the fastest home improvement projects.

Roofing repairs may be an option for your Rockville roof. If your roof is less than 10 years old and has missing shingles or a roof leak, repairing it may be your best decision. Things to consider.... Roofing shingles fade over time so cosmetically any new shingles will have a slightly different apperance. If your roof is over 10 years old, the long term costs will be higher after you invest in repairs and then need a replacement in the future. Your roofer should discuss your options before you decide on a roof replacement. Roof repairs generally range from $1,000-$3,000. This could go toward the cost of a new roof with a 50 year warranty. If you plan to stay in your home long term roof replacement is generally the best long term option to protect your home and save money. Be sure to weigh both options before hiring a Rockville roofer.
