"Precision Roofing were fine. They did the job and the roof has been fine, it's been raining a lot and it's been okay. I have no complaints as far as that is concerned. My main thing was having the roof repaired and they did it. I may use them again."

"After years of wear and several heavy storms, our old roof finally started showing serious signs of damage. Shingles were missing and we began noticing small leaks inside the house. We contacted Dalmatia Roofing for a full roof replacement, and their team responded quickly. They inspected the roof carefully and explained the entire replacement process in a clear and professional way."

Roofing FAQs, answered by experts

A roof pitch multiplier is an accurate way to calculate roof square footage, and it’s handy for purchasing the correct amount of materials. To determine your roof pitch multiplier, you'll need to calculate the roof slope, square it, and add it to 144. Next, find the square root of the total and divide it by 12. The answer is your roof pitch multiplier. Once you know the roof pitch multiplier, multiply it by the total square feet of your building to determine the total roof surface area.

Walking on any roofing material is dangerous, so you should avoid it if you can, but if the need arises, you should know that you can walk on a concrete tile roof without damaging it. Try to step on the bottom portions of the tile that are supported by the lower layer, and distribute your weight evenly across both feet and hands, if possible.

A standard roof can hold a live load of about 20 pounds per square foot. However, gable roofs often have steeper-than-average slopes, so calculating their weight capacity can be challenging. If the slope of your gable roof is greater than 4:12, the live load needs to be decreased to allow for a larger dead load. Ask your roofer exactly how much weight your roof can support.

A chimney cap costs about $300 on average to install, with prices ranging from $75 to $1,000. The final cost depends on several factors, including the professional you hire, the accessibility of your chimney, the cap's material and size, whether any repairs are needed, and if it requires custom fabrication. Chimney caps are usually made from galvanized steel, stainless steel, or copper. Copper caps are the most expensive, followed by stainless steel and then galvanized steel. Excluding labor, average material costs are around $100 for galvanized steel, $250 for stainless steel, and $600 for copper. You may also face additional costs, such as hiring a chimney sweep to clean the chimney before the cap is installed.

The cost to install a drip edge on an existing roof runs about $1 to $3 per linear foot, which comes out to between $150 and $1,000, with an average cost of $575. These are just averages; the total project price can vary depending on the type of drip edge chosen and whether you hire a professional for the installation. Factors like roof size, complexity, and labor rates also play a role in determining the final cost.
