"Contracted Federal Building and Roofing with Richard and his team after Listening to Richard's suggestions during the estimate. Had bad water damage to many Rafter Tails as well as a severe leak in the garage, Had several Contractors out for estimates some wanting to go a much more expensive route to repair the damaged wood on the Rafters as well as suggesting a complete Torch down on the entire roof which was not needed, which came with a less than desirable Warranty along with higher costs. Richard gave me peace of mind with his knowledge and suggestions which in turn provided a much longer Warranty and cheaper more effective route to repairing the damaged Rafter tails,all at a very reasonable price compared to other estimates. Any Contractor should have been able to provide me with these suggestions and alternatives but failed to do so. Richard and his team were Professional, polite,cleaned up thoroughly each and every day and completed the job on time as scheduled."

"They were kind and efficient. I had to be diligent and push them to do a water test of the roof or else they would have diagnosed it with the wrong issue. But other than that, they were able to perform the work and solve the issue. It ended up needing a flashing maintenance rather than to re-do a whole portion of my roof (big difference... $1,500 vs. $4,500)"

Roofing FAQs, answered by experts

While you don’t have to let roofers inside your home, it is proper etiquette to offer the use of your restrooms. And if it’s a hot day, it’s polite to invite the roofers into your house to cool off and have a chilled drink.

You should avoid choosing a metal roof if your home has a weak structural support system, as metal roofs can be heavier than roofs made of other materials. If you're in a region prone to frequent hailstorms or high winds, you also need to be aware that denting may occur.

Most roof leaks occur where shingles meet or where there are sealants or seams in the materials. This is common around skylights and at any point there is a break in the roof such as corners and edges. Roofing materials are incredibly strong and resistant when overlapping, but any change in that can cause gaps where water can enter.

Whether you should choose a flat roof or a sloped roof depends on your particular situation. Flat roofs tend to be less expensive to install. However, sloped roofs have longer lifespans and stand up better to heavy snow and other inclement weather.

Keep in mind that even a flat roof needs to have a slight slope, usually around 1/2 inch for every foot. If it is completely flat, water will pool and cause damage, either from weight or leakage or rot.

The most common slope, or roof pitch, for a shed is 4:12 or four inches of height for every horizontal foot. For areas that experience heavy snow loads, a steeper roof of 6:12 or 9:12 is best.
