"This is the second time we use Richard and his team at Federal Building & Roofing, and they have been excellent. This time, due to the many homes with roof damage from the heavy winds/rain, it took a bit longer to schedule, but he got it done on a Saturday, and right in time before more rain. Professional, Good Quality Work and Dependable."

"Highly recommended! Adam Tweedy and his team repaired our 'cool roof' and three patio decks in just two days. The crew was efficient, careful with our furniture, and the installation was impressive. The roof passed the water test, proving its quality. An added bonus: they didn’t need to remove our solar panels, saving us time and money. For a reliable, water-tight roof at a reasonable price, call Reign Roofing!"

"All went well, roof looks great! People walked in the neighborhood and would comment that the progress was looking good. I picked Hoyt out for 4 bids. The city inspector said when I asked him if they did a good job, he said yes and he would recommend them."

"Eric came out for the estimate and provided the various options and what he would generally provide. He was patient (Unlike Skyline Roofing)in our vacillation between concrete tile and composition shingles (Provided samples for both types)and also a delay in schedule due to tenting for termites. His price estimate was in line with other estimates (Except iRoof which was almost twice as much as everyone else) He provided a complete package without me asking, including radiant barrier sheathing, roof vents, new flashings, replacement of dry rot wood (included in the overall price) etc. There was a delay in the start date due to rain (Rain in SoCal?) The first day his crew (very friendly) showed up early and did not waste any time tearing off the 40 year old concrete tile roof. Second day they completed the tear off, did some structural repairs I had asked for and started sheathing (required due to the original spaced sheathing construction) Third day (Friday)completed sheathing, building department inspection (permit etc all handled by Eric) and began installation of the felts and composition shingles. They returned on Monday to complete the roof and clean up, with final building department inspection on Tuesday. Very pleased with the final product and the clean up that the crew did. We are now ready for El Nino!"

Roofing questions, answered by experts

Yes, moss can be dangerous for your roof if left in place to grow without treatment. The moss soaks up and holds moisture. Having a constantly damp roof could lead to problems with rot for the parts of the roof that consist of wood. Additionally, a patch of thick moss may draw insects and birds, which could damage the roof. Thick moss could block the roof’s drainage system. Water then may back up after a rainstorm and cause further damage that could eventually lead to roof repair expenses or the cost of roof replacement.

Copper roofs last an average of around 100 years, making it one of the longest-lasting types of roofs. It’s significantly more expensive than an asphalt shingle roof, but it also lasts three to four times as long, providing great value for the money. You can extend the life of your copper roof by carrying out routine maintenance, like scheduling annual cleaning and roof inspections.

There are several pros and cons of flat roofs. One disadvantage of flat roofs is that you lose potential attic space because it's flat. Flat roofs tend to pool water and because they lack an angle, any leak in the roof—usually due to a bad seal—has the potential to let in a lot of water. They don’t work well in climates with snow. Flat roofs are also structurally weaker than sloped roofs.

The most important thing to remember when laying shingles is to work from the bottom of the slope to the top. This leaves you with a top overlap that directs runoff from one row to the next until it reaches the eave for disposal. You should also make sure you follow the manufacturer's instructions and the local building code for nailing patterns and frequency so all of your hard work stays put through varying weather conditions.

Yes, but it won't be as effective as installing it as part of a new roof because it won't be as water-resistant. However, a drip edge installed after the fact is better than no drip edge at all.
