"This was my second project with HEXAGON CONSTRUCTION and by far the largest and most complex. (Replacing an old, clay tile roof on a three story house is no job for a rookie.) HEXAGON’s owner, Eli Vatkin, is what everyone should be looking for in a contractor. He’s knowledgeable, reasonably priced, trustworthy, responds promptly to any concerns that you have during the project, keeps you apprised of its progress, finishes on time, and generally aims to please. His contracts were straightforward and “by the book.” On top of that, he’s a genuinely nice guy. Rarely will you find all these qualities in a contractor—and I’ve been around long enough to know. "

"We spoke with a few contractors to determine the best fit for our needed repairs. Aaron M. from Modern Roofing came & fully inspected the damages inside and out. He was able to determine that our roof, designed in 1997, had a flaw in the flashing and tile placement . We discussed the scope of work needed to fix the flaws properly. Aaron was so nice, kind, knowledgeable, articulate, and compassionate that he was able to completely put our minds and anxiety (caused by others) at ease so adequately that the repairs started the next day. Aaron was superb in his communication with us and overseeing the repairs. His employees were very courteous as well as highly skilled in their trade. Aaron also implemented a higher level of safety due to our disabilities & visiting grandchildren. The work performed on our house completed to a very high standard. Aaron was an absolute pleasure to work and we look forward to working with him and Modern Roofing in the future. "

FAQs for asphalt shingle roofing installation and replacement projects in Monrovia, CA

Roofing professionals can usually install a medium-sized asphalt shingle roof in two to three days. Installation time increases if your roof is particularly steep or difficult to access or has features like chimneys or skylights that roofers must work around.

Three-tab asphalt shingles usually have the lowest upfront cost of any roofing shingle material. They’re sturdy and typically last 15 to 20 years. However, they may have a shorter lifespan in especially hot or cold climates. Talk to a local roofing professional about the best materials for your climate. In some cases, materials with a higher upfront cost may save you more on repairs or replacements in the long run.

Start by multiplying the length by the width of your roof to calculate the square footage. Most shingle replacement costs $4 to $12 per square foot for materials and labor, depending on factors like the material and the slope of your roof. Once you know the size of your roof, you can calculate a rough estimate of total costs or contact a local roofing professional to provide you with a custom quote.

Asphalt shingles are generally considered to be a low-maintenance item. However, cleaning your asphalt roofing can help prolong the lifespan and keep it looking fresh. If you’re comfortable with DIY and have the proper equipment, you may be able to clean your asphalt shingles yourself. However, if you have an especially high or steep roof, it’s usually safer to hire a professional roof cleaner.
